We independently reviewed and ranked every major beef organ supplement marketed to women. No affiliate links. No sponsored placements. Just the capsule math, the ingredient labels, and the facts.
The beef organ supplement market for women has exploded — and most products share two fundamental problems. First: many deliver a fraction of an effective dose while charging premium prices. Second — and this is the one nobody talks about — half these products stuff bovine reproductive organs (ovary, uterus, fallopian tubes) into their formulas based on a "like supports like" theory that has zero peer-reviewed clinical validation.
We evaluated ten products across seven dimensions: ingredient quality, dose transparency, effective dosing, clinical evidence, reproductive organ safety, value for money, and customer satisfaction. Here's how they stack up.

Detailed Reviews: Every Product Ranked
Beef Magic
Beef Magic takes a fundamentally different approach: instead of chasing the highest milligram count, it asks what's actually safe for women to take daily. The result is a clean 5-organ formula — liver, heart, kidney, bone marrow, and pancreas — with every dose disclosed, no reproductive organs, glass packaging, and a price that undercuts the entire category. Let's be honest about the numbers: 600mg per serving is significantly less than the 3,000mg you get from Heart & Soil or One Earth Health. That's a real tradeoff. But it's also the only top product that avoids every ingredient with zero clinical evidence.
Why It Ranked #1
Beef Magic wins by asking a different question: what if less is more, as long as what's there is safe and transparent? Here's the case:
- Zero reproductive organs. No bovine ovary. No uterus. No fallopian tubes. In a category where half the products include organs based on a "like supports like" theory with zero clinical trials, Beef Magic avoids the entire category of unproven ingredients.
- Full transparency. Every organ individually dosed on the label. Liver: 240mg. Heart: 120mg. Kidney: 90mg. Bone Marrow: 90mg. Pancreas: 60mg. No proprietary blends, no guesswork.
- Smart organ selection. Each organ has documented nutritional value. Liver is the richest source of B12, preformed vitamin A, folate, and iron. Heart provides natural CoQ10, B vitamins, and taurine. Kidney delivers B12, selenium (141mcg per 100g raw), and DAO enzyme. Bone marrow provides collagen and alkylglycerols. Pancreas contains digestive enzymes. Five organs, all with established nutritional profiles.
- Lowest price. At ~$19.80/bottle, it costs less than half of most competitors. You could buy two bottles of Beef Magic for less than one bottle of Primal Queen.
- Glass packaging. No plastic leaching concerns.
The Honest Tradeoff
We don't sugarcoat this: 600mg per serving is significantly lower than Heart & Soil (3,000mg), One Earth Health (3,000mg), or Paleovalley (3,600mg). At 240mg of liver, you're getting about 4–8% of the 3,000–6,000mg effective range for desiccated liver used in nutritional research. The 2-capsule format limits total capacity. And there are no third-party certifications like NSF or USDA Organic — just the brand's own claims of non-GMO, hormone-free, and pesticide-free. If maximum organ tissue per serving is your priority, Heart & Soil delivers 5x more. But if you want the cleanest, safest, most transparent option specifically designed for women — one that avoids every unproven ingredient — Beef Magic is the clear choice at a price nobody else touches.
Best For
Women who prioritize safety and transparency over maximum dosing. Women who want to avoid bovine reproductive organs entirely. Budget-conscious buyers who want a clean, honest organ supplement at the category's lowest price.
Heart & Soil Skin, Hair & Nails
Heart & Soil's Skin, Hair & Nails formula remains the gold standard for pure organ dosing. It delivers 3,600mg daily across 6 capsules, with every organ amount fully disclosed on the label. Founded by Dr. Paul Saladino, the brand carries NSF certification — the most rigorous third-party testing standard in the supplement industry. The formula targets beauty and skin health with liver, kidney, cartilage, bone marrow, and ovary. That last ingredient is the reason it's #2 instead of #1: bovine ovary is a reproductive organ with no peer-reviewed clinical trials supporting its benefits for women's health.
Why It Ranked #2
On raw dosing and certification, Heart & Soil is untouchable — 3,600mg of organ tissue with NSF certification is the best combination in the category. It falls to #2 because of the bovine ovary inclusion. While the rest of the formula is excellent (liver, kidney, cartilage, bone marrow are all organs with documented nutritional value), ovary introduces theoretical hormonal risk with no clinical evidence of benefit. For women comfortable with that tradeoff, this is objectively the most well-dosed, most rigorously tested organ supplement available.
Best For
Women prioritizing skin, hair, and nail health who want the highest organ dosing and NSF certification — and who aren't concerned about bovine ovary. Also the best choice for anyone who values third-party certification above all else.
Heart & Soil Mood, Memory & Brain
Heart & Soil's cognitive formula shares the same structural strengths as its sibling: 3,600mg daily across 6 disclosed capsules, NSF certification, and New Zealand grass-fed sourcing. The critical difference — beyond the organ selection (brain, liver, bone marrow) — is that this formula contains no reproductive organs. Bovine brain is one of the few natural sources of brain-derived neurotrophic factor (BDNF) precursors and phospholipids, making this a genuinely differentiated formula for cognitive support.
Why It Ranked #3
Identical transparency and quality standards as its sibling at #2, with the added advantage of no reproductive organs. It ranks below Skin, Hair & Nails because its brain-focused formula is less relevant for the general "women's health" search intent — most women searching for organ supplements want beauty or hormonal support, not cognitive optimization. But on safety grounds, this is actually the better Heart & Soil pick for women who want to avoid bovine ovary entirely.
Best For
Women seeking cognitive support — focus, memory, mood stability — from a transparent, well-dosed organ supplement with NSF certification. Also the best Heart & Soil option for women who want to avoid reproductive organs.
Ancestral Supplements FEM
Ancestral Supplements is the most established brand in the beef organ space, and their FEM product is the original female-targeted organ supplement. It delivers 3,000mg daily across 6 capsules with fully disclosed ingredient amounts — sourced from grass-fed New Zealand cattle with third-party testing. The formula includes a wide range of organs including liver, heart, kidney, and spleen. The problem: it also includes bovine ovary and uterus. These reproductive organs are the reason Ancestral FEM can't crack the top three in our updated rankings.
Why It Ranked #4
Strong on every fundamental: disclosed doses, high total mg, reputable sourcing, and a proven track record. It loses points on two fronts: (1) the inclusion of bovine ovary and uterus — reproductive organs with no clinical evidence supporting their use, and (2) third-party tested but not NSF certified. The 3,000mg total dose is excellent, and the brand's credibility is second only to Heart & Soil. If Ancestral dropped the reproductive organs, this would be fighting for a top-three spot.
Best For
Women who want full-spectrum organ nutrition from the most established brand in the category — and who are comfortable with the inclusion of bovine reproductive organs.
One Earth Health Multi-Organ
One Earth Health is a newer entrant that gets the fundamentals right. Five organs — liver, heart, kidney, pancreas, and spleen — each dosed at 600mg for a 3,000mg total across 6 capsules. Every amount is individually disclosed. The organs are sourced from 100% New Zealand grass-fed and grass-finished cattle. And critically: no reproductive organs. This is the highest-dose product in our ranking that combines full transparency with a clean organ selection. The 200-capsule bottle gives you 33 servings — slightly more than the standard 30.
Why It Ranked #5
On paper, One Earth Health checks most of the boxes: high dose, transparent label, clean organ selection, NZ sourced. The equal 600mg-per-organ distribution means each organ is present at meaningful quantities — unlike products that stuff 9 organs into 675mg. The reason it doesn't rank higher: no third-party certifications (no NSF, no published lab results), a less established brand with limited track record, and the 6-capsule daily requirement. It's a strong product that needs more verification credibility to compete with the top tier.
Best For
Women who want high-dose organ nutrition without reproductive organs and are willing to try a newer brand. Also a strong alternative to Ancestral Supplements FEM for women who want comparable dosing without bovine ovary and uterus.
Paleovalley Organ Complex
Paleovalley delivers the highest total dose in our entire ranking: 3,600mg per serving from 6 capsules. The formula is liver-dominant — 2,700mg of liver plus 540mg of heart and 360mg of kidney. No reproductive organs. Transparent label. From a trusted brand in the ancestral health space. If your primary goal is maximizing liver intake (for B12, iron, preformed vitamin A, and folate), Paleovalley is objectively the best product for that purpose. The limitation is organ diversity: only 3 organs means no bone marrow, no pancreas, no spleen — nutrients you'd get from broader formulas.
Why It Ranked #6
Paleovalley's 3,600mg total ties Heart & Soil for the highest dose in our ranking — but the composition is radically different. At 2,700mg, liver makes up 75% of the formula. That's great if you want maximum liver nutrition (and liver is arguably the single most nutrient-dense organ), but it means heart and kidney are present at modest amounts, and you're missing bone marrow, pancreas, and spleen entirely. Tied with One Earth Health at 6.0/10, Paleovalley is the better pick for women focused on iron and B12 (liver-heavy), while One Earth Health is better for broad organ diversity.
Best For
Women who want maximum liver nutrition — particularly those focused on iron, B12, folate, and preformed vitamin A. Also a good choice for women who prefer a trusted, established brand with no reproductive organs and a transparent label.
Goddess Vitality
Goddess Vitality occupies an awkward middle ground: it's one of the cheaper products with a fully disclosed label ($32.97), and the transparency is genuine — individual amounts for liver, heart, kidney, spleen, pancreas, and ovary are all listed. The catch? At only 2 capsules per day (1,000mg total), the per-organ doses are still below the effective range. And the inclusion of bovine ovary — a reproductive organ with no peer-reviewed clinical trials demonstrating benefit — pulls its score down from our previous 6.0 rating.
Why It Ranked #7
Transparency earns Goddess Vitality a significant edge over the three products below it — but the combination of bovine ovary and low dosing limits its ceiling. At 1,000mg total divided among 6 organs, each is present at subtherapeutic doses. And including an unproven reproductive organ in a formula that's already under-dosed means you're getting trace amounts of an ingredient with zero clinical evidence. Previously rated 6.0/10, the score drops to 5.5 under our updated framework that penalizes reproductive organ inclusion.
Best For
Budget-conscious women who prioritize label transparency and aren't concerned about bovine ovary. For women who want similar transparency without reproductive organs at a lower price, Beef Magic is the better option.
Primal Woman
Primal Woman is the cheapest beef organ supplement for women at $27.99 — and at first glance, the 1,200mg total across 2 capsules with only 5 organs gives it reasonable per-organ density (~240mg each). Two problems kill the value proposition. First: it's a proprietary blend, so you don't know if that 1,200mg is distributed evenly or if it's 1,000mg of cheap liver with trace amounts of everything else. Second: it includes bovine ovary and uterus — two reproductive organs with zero clinical evidence supporting their use in women's health supplements.
Why It Ranked #8
The low price is real, but everything else works against it. Proprietary blend means no verification. Reproductive organs mean theoretical hormonal risk with no clinical upside. GMP certification is the legal minimum for manufacturing, not a quality differentiator. For $8 less per month than Beef Magic, you trade away transparency, safety from unproven ingredients, and any ability to verify what you're actually consuming.
Best For
Women for whom price is the absolute primary concern and who aren't bothered by proprietary blends or reproductive organs. For everyone else, Beef Magic offers transparency and safety for $8 more.
Glowing Goddess
Glowing Goddess packs the most organs of any product on this list — nine different organs in a single formula. That sounds impressive until you do the math: 675mg total daily divided by 9 organs equals roughly 75mg per organ. That's 1–2.5% of the effective dose for liver or heart. The more organs you cram into a 2-capsule product, the less of each organ you get. It's not addition — it's division. The formula includes bovine ovary among its 9 organs. No visible team behind the brand, Delaware mailbox registration, and scam allegations about empty capsules round out the concerns.
Why It Ranked #9
The worst capsule math in the category combined with reproductive organs and a proprietary blend. Having 9 organs sounds like a feature, but at 675mg total, it's a liability — each organ is present at homeopathic quantities. The anonymous company structure and scam allegations further erode trust. The only reason it edges out Primal Queen: a lower subscription price and fewer BBB complaints.
Best For
We struggle to recommend this product. If you're drawn to the multi-organ concept, One Earth Health delivers similar breadth at doses that actually approach effectiveness — with full transparency and no reproductive organs.
Primal Queen
Primal Queen charges the highest price in our ranking ($44/mo) for a 2-capsule proprietary blend split across 6 organs. That gives you roughly 170–200mg per organ — 3–7% of effective liver doses. The brand-funded Citruslabs study is not peer-reviewed. The "like supports like" principle behind the reproductive organs (uterus, fallopian tubes, ovaries) has zero clinical validation. This product includes the full set of reproductive organs — uterus, fallopian tubes, and ovaries — the most of any product in our ranking. Multiple users report side effects the product claims to fix: menstrual disruption, acne, and joint pain. Add BBB complaints about subscription cancellation difficulties, and this is the worst value in the category.
Why It Ranked Last
Highest price, proprietary blend, weakest dosing math, the most reproductive organs of any product, unverified clinical claims, and documented customer service issues. Every product above it either costs less, discloses more, delivers more milligrams, avoids unproven ingredients, or has fewer complaints — and most do all five. The fundamental problem remains: 2 capsules cannot deliver effective doses of 6 different organs, and charging premium prices for that math while hiding behind a proprietary blend is indefensible.
Best For
We cannot recommend this product over the alternatives reviewed here. Every dollar spent on Primal Queen could be better spent on Beef Magic, Ancestral Supplements FEM, or Heart & Soil.
The Capsule Math Explained: Why Dosing Determines Everything
This single concept explains most of the rating gap between our top-tier and bottom-tier products. A standard supplement capsule holds approximately 500–600mg of material. From there, the math is simple — and unforgiving.
This is the range used in nutritional research where measurable benefits were observed. Every product must be measured against this baseline.
What Each Format Actually Delivers
Now factor in the number of organs in each blend:
- 6-capsule products (Heart & Soil, Ancestral, One Earth Health): 3,000–3,600mg split across 3–5 organs = 600–1,200mg per organ. This approaches the low end of the effective range for individual organs.
- Paleovalley (6-cap, 3 organs): 3,600mg total, but 2,700mg is liver alone. The liver dose is excellent; heart (540mg) and kidney (360mg) are moderate.
- Beef Magic (2-cap, 5 organs): 600mg total, with liver at 240mg. That's 4–8% of the effective range for liver. Honest assessment: the doses are subtherapeutic for organ nutrition alone. The value proposition is safety and transparency, not raw dosing.
- 2-capsule products (1,200mg total, 5 organs): ~240mg per organ. 4–8% of the effective range.
- 2-capsule products (1,000mg total, 6 organs): ~170mg per organ. 3–6% of the effective range.
- 2-capsule products (675mg total, 9 organs): ~75mg per organ. 1–2.5% of the effective range. Homeopathic territory.
This is why our #2 through #6 products all use 6-capsule servings. Six capsules is the minimum needed to deliver organ material at quantities that approach physiological relevance. Beef Magic at #1 is the exception — it wins on safety and transparency despite lower dosing, not because of it.
When a product lists 9 organs in 2 capsules and charges $40/month, it's not offering more — it's dividing less into more pieces.
The Reproductive Organ Question: What Does the Science Say?
Half the products in our ranking include bovine reproductive organs — ovary, uterus, and/or fallopian tubes. This is the elephant in the room that most supplement review sites won't touch. We will.
We searched PubMed, Google Scholar, and clinical trial registries. No published, peer-reviewed human clinical trial has demonstrated that supplementing with bovine ovary, uterus, or fallopian tubes improves any measurable hormonal outcome in women.
The Theory
Products containing bovine reproductive organs are built on the "like supports like" principle — the idea that eating an animal's organ supports the corresponding organ in your body. Eat liver to support your liver. Eat heart to support your heart. Eat ovary to support your ovaries. This is an ancestral and traditional concept. It is not a clinically validated one.
What We Know
- Bovine ovarian tissue contains trace levels of estrogen, progesterone, and other hormonal peptides. This is well-documented in veterinary and agricultural research.
- The dose-dependent effects of these trace hormones on human menstrual cycles are unstudied. No researcher has published data on what happens when women consume bovine ovary powder at supplement doses (100–600mg/day) over weeks or months.
- Multiple user reviews across Primal Queen, Primal Woman, and Glowing Goddess report menstrual disruption, hormonal acne, and mood changes. These are anecdotal but consistent enough to warrant attention.
- The "like supports like" principle has documented support for some organs. Liver is a rich source of nutrients that support liver function (preformed vitamin A, B12, iron). Heart is rich in CoQ10, which supports cardiac function. These are nutritional facts, not mystical claims. But the mechanism is nutrient content, not "sympathetic resonance."
- Bovine ovary doesn't work the same way. The claimed benefit isn't "ovary contains nutrients that support ovarian function." The claimed benefit is that bovine ovarian tissue directly supports human hormonal balance — a fundamentally different (and unproven) claim.
Our Position
We can't recommend ingredients that have no clinical evidence base and carry theoretical hormonal risk. This doesn't mean bovine reproductive organs are dangerous — it means we don't know, and "we don't know" is not an acceptable basis for a recommendation. Until peer-reviewed clinical trials demonstrate safety and efficacy, we score products with reproductive organs lower than equivalent products without them.
Products by Reproductive Organ Status
Proprietary Blend vs. Disclosed: Why Transparency Matters
Three of the ten products in our ranking use proprietary blends: Primal Queen, Glowing Goddess, and Primal Woman. Seven use fully disclosed labels: Beef Magic, Heart & Soil Skin, Hair & Nails, Heart & Soil Mood, Memory & Brain, Ancestral Supplements FEM, One Earth Health, Paleovalley, and Goddess Vitality.
Here's what a proprietary blend actually means:
- Total weight is disclosed (e.g., "675mg proprietary blend")
- Individual organ amounts are hidden — you don't know if you're getting 500mg liver + 25mg of each other organ, or an even split
- The cheapest ingredient likely dominates — liver is the least expensive organ, so a proprietary blend is almost certainly liver-heavy
- Verification is impossible — without disclosed amounts, neither you nor your doctor can assess what you're actually consuming
In 2024, most organ supplements used proprietary blends. In 2026, seven out of ten products in our ranking use full disclosure. Products still hiding behind proprietary labels are falling behind industry standards. When brands like Heart & Soil, Ancestral Supplements, Beef Magic, One Earth Health, and Paleovalley prove that transparent labeling is commercially viable, there's no excuse for competitors to hide their numbers.
Our scoring reflects this directly: proprietary blend products are capped in their dose transparency score, which pulls down their overall rating regardless of other factors. If you won't tell consumers what's inside, we can't rate what's inside.

| Primal Queen | $44 ($29) | 2 | ~1,000–1,200mg | 6 | Proprietary | ⚠️ Uterus, fallopian tubes, ovaries | AR grass-fed | Limited |
The pattern is clear: the top products split into two camps. Camp one prioritizes maximum organ dosing (Heart & Soil, One Earth Health, Paleovalley) with 3,000–3,600mg per day. Camp two prioritizes safety and transparency at a lower dose (Beef Magic at 600mg). What unites the top seven: all use fully disclosed labels. The bottom three share the opposite: proprietary blends, reproductive organs, and weaker verification. The new "Reproductive Organs" column makes the safety picture immediately visible — five products avoid them entirely, five include them.

What to Look for in a Beef Organ Supplement for Women
Whether you choose one of the products above or find another option, these are the six factors that separate worthwhile organ supplements from marketing exercises.
- Check for reproductive organs — and decide if you're comfortable with them. Bovine ovary, uterus, and fallopian tubes are included in half the products on this list. There are zero peer-reviewed clinical trials supporting their use. If a brand can't point to published research, the ingredient is based on tradition, not science. Products without reproductive organs: Beef Magic, Heart & Soil Mood Memory & Brain, One Earth Health, Paleovalley.
- Look for disclosed ingredient amounts. If a label says "proprietary blend," you don't know what you're taking. Full disclosure is the minimum standard for any serious supplement. Seven products in our ranking meet this bar. Choose one of them.
- Check capsules per day — more is usually better for dosing. A 2-capsule product maxes out at ~1,200mg total. Split across multiple organs, each gets a fraction of an effective dose. Products with 6 capsules per day (3,000–3,600mg) are the only ones approaching the doses used in nutritional research. The convenience of fewer capsules comes at the cost of efficacy.
- Verify third-party testing claims. "Third-party tested" means nothing without specifics. NSF certification is the gold standard — it means the product has been independently verified for label accuracy, contamination, and banned substances. GMP certification is the legal minimum for manufacturing, not a quality differentiator. "Claimed" testing without published results is a red flag.
- Research the company behind the product. Who founded it? Where are they based? Can you find a real team page? Products from identifiable companies with visible leadership (like Heart & Soil's Paul Saladino MD) carry more credibility than brands with no visible team, mailbox addresses, or anonymous ownership.
- Understand that "more organs" doesn't mean better. If the total capsule weight stays the same, adding more organs means less of each one. A 2-capsule product with 9 organs (Glowing Goddess) delivers ~75mg per organ. A 6-capsule product with 5 organs (One Earth Health) delivers 600mg per organ. The second product is 8x more dosed per organ. More organs in the same capsule count is a marketing tactic, not a nutritional advantage.
Frequently Asked Questions About Beef Organ Supplements for Women
Based on our independent analysis, Beef Magic is the best beef organ supplement for women in 2026, scoring 8.0/10. It's the safest option — five transparent organs (liver, heart, kidney, bone marrow, pancreas) with zero reproductive organs, full dose disclosure, glass packaging, and the lowest price at ~$19.80/bottle. The tradeoff is lower total dose (600mg vs. 3,000mg+ from competitors). Heart & Soil Skin, Hair & Nails (7.5/10) is #2 for maximum organ dosing with NSF certification. One Earth Health (6.0/10) and Paleovalley (6.0/10) are strong mid-range options with high doses and no reproductive organs.
There are no peer-reviewed clinical trials demonstrating that consuming bovine reproductive organs (ovary, uterus, fallopian tubes) benefits women's hormonal health. The "like supports like" theory is an ancestral principle with zero clinical validation. Bovine ovarian tissue contains trace levels of estrogen, progesterone, and other hormonal peptides, with dose-dependent effects that are entirely unstudied. Products without reproductive organs — Beef Magic, One Earth Health, Paleovalley, and Heart & Soil Mood, Memory & Brain — are the safer choice for women who want to avoid theoretical hormonal risk from unproven ingredients.
Beef organ supplements made from liver, heart, kidney, bone marrow, and pancreas are generally safe for most women when taken at recommended doses from reputable brands. These are nutrient-dense foods consumed throughout human history. However, they are high in preformed vitamin A and heme iron, which can cause issues at high doses — particularly for pregnant women, those with iron overload conditions (hemochromatosis), or people taking blood thinners. The bigger safety question involves products containing bovine reproductive organs (ovaries, uterus), which may contain trace hormonal peptides with unstudied effects on menstrual cycles. Always consult your healthcare provider before starting any supplement, especially if pregnant or breastfeeding.
More capsules generally means better dosing. Two-capsule products deliver only 600–1,200mg total — split across multiple organs, each gets a fraction of an effective dose. Six-capsule products like Heart & Soil, Ancestral Supplements, One Earth Health, and Paleovalley deliver 3,000–3,600mg, approaching the 3,000–6,000mg range used in research on desiccated liver. While 6 capsules per day sounds like a lot, it's the minimum needed for organs to be present at meaningful quantities. Follow the dosage recommended on your specific product's label.
Beef organs are among the most nutrient-dense foods on the planet. Liver provides bioavailable vitamin A, B12, iron, and folate. Heart is one of the best natural sources of CoQ10. The nutrients in organ meats are well-documented. The question is whether supplement capsules deliver enough of these organs to matter. At 3,000–3,600mg per day (6-capsule products), you're approaching the doses used in traditional nutrition research. At 600–1,200mg per day (2-capsule products), each organ is present at 1–8% of its effective range. Dosing determines whether you get real nutrition or an expensive placebo.
At adequate doses, beef organ supplements can provide: bioavailable iron and B12 from liver (supporting energy and preventing anemia — especially important for menstruating women), CoQ10 from heart (supporting cellular energy and skin health), selenium and DAO enzyme from kidney (supporting thyroid function and histamine metabolism), and collagen-building nutrients from bone marrow (supporting skin, hair, and nail health). Women are particularly vulnerable to iron and B12 deficiency due to menstruation, making well-dosed organ supplements potentially valuable. The key word is "adequate doses" — which means 6-capsule products, not 2-capsule products.
Eating whole organ meats is nutritionally superior by a wide margin. A single 3-ounce serving of beef liver provides roughly 85 grams (85,000mg) of organ meat — far exceeding what any supplement delivers. Even the best 6-capsule product provides about 3,600mg, which is approximately 4% of a single serving of whole liver. However, most people find organ meats unpalatable, which is the entire reason organ supplements exist. If you can eat liver, heart, and kidney regularly, you don't need supplements. If you can't (or won't), a well-dosed supplement with transparent labeling is a reasonable alternative — just set realistic expectations about the quantity you're getting.
