HelloPharmacist Scorecard of Georges St Pierre's Warrior by Heart & Soil

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Georges St Pierre's Warrior contains 2 active ingredients: bovine liver and bovine heart. Bovine liver is organ tissue that delivers nutrients including vitamin A and iron.

Bovine heart similarly provides organ-sourced nutrients. The capsules also contain gelatin as an inactive ingredient.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Liver Extract's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: strength and recovery.
  • We looked for evidence on: Chronic fatigue syndrome (CFS), athletic performance, muscle recovery, stamina.
  • The closest evidence on file: Liver Extract is rated "Possibly Ineffective" for Chronic fatigue syndrome (CFS) (Natural Medicines).

The evidence for bovine liver in chronic fatigue syndrome is rated possibly ineffective — meaning it doesn't appear to help. For hepatitis C, we don't have enough reliable evidence to rate it either way.

We hold no effectiveness data for bovine heart.

The evidence, ingredient by ingredient Liver Extract

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

No adverse reactions from bovine liver have been reported, but a thorough safety evaluation hasn't been done. The main concerns are source quality: liver extract comes from raw animal liver at slaughterhouses, potentially from sick or diseased animals, and there's a theoretical risk of contamination with diseased tissue in products from countries where BSE (mad cow disease) has been found — though no human BSE cases from liver extract have ever been reported.

Bovine liver delivers very high levels of vitamin A and iron, which can be harmful at high doses or with prolonged use. Pregnant people should avoid it unless their doctor advises otherwise, since excess vitamin A may harm a developing baby.

Safety during breastfeeding hasn't been well studied — talk with your doctor or pharmacist before using.

Side effects, ingredient by ingredient Liver Extract

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Liver Extract.
  • The most serious interaction on file is rated Minor.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 3 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you start, double-check warfarin (Coumadin) — the vitamin K content could reduce its effectiveness. Also verify any iron supplements or iron-containing medications you're taking, since this product contains heme iron and combining them could increase your iron load.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

This product might appeal to people interested in organ-based nutrition, but the evidence doesn't support it for chronic fatigue or hepatitis C. If you take warfarin or iron supplements, check with us first.

The biggest caution is source safety — know where your liver extract comes from, and talk with your pharmacist about whether this brand addresses those concerns.

General Statements

Fall down seven times get up eight Everyone falls down in life, but a Warrior always stands up to fight again. And to summon the strength to stand back up every time demands the best nutrition. This is why I demand animal organs like the heart and liver, which pound for pound, are the most nutritious and powerful foods to exist.

All alpha predators instinctively know this, which is why when wolves and lions kill an animal, they eat the heart and liver first. Our warrior ancestors also knew the power of these foods, seeking them above all others. I believe 100% in the power of these foods. I believe they will give you the strength to get back up when life knocks you down and allow you to live your life as a true warrior. Georges "Rush" St-Pierre

Bovine Liver2 drug types · 3 drugs

Iron

Liver extract can contain heme iron. Taking liver extract with iron-containing medications or supplements may increase total iron intake and could increase the risk of gastrointestinal adverse effects or excessive iron accumulation. The risk is greater with high doses, prolonged use, or in individuals with hemochromatosis or another iron-overload disorder. Review the iron content of the liver extract and the total elemental iron dose. Avoid unnecessary duplicate iron supplementation and consider monitoring ferritin and transferrin saturation when clinically appropriate.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Liver extract products may contain small and variable amounts of vitamin K. Theoretically, starting, stopping, or substantially changing the amount of liver extract used could reduce the anticoagulant effect of warfarin and lower the INR. However, this interaction has not been directly studied or reported in humans, and the vitamin K content of liver extract products is generally not standardized. Consider monitoring the INR after a meaningful change in liver extract use.

Georges St Pierre's Warrior by Heart & Soil: Common Questions

Does Georges St Pierre's Warrior by Heart & Soil interact with any medications?
Yes. Based on its ingredients, Georges St Pierre's Warrior has a known interaction with 3 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Georges St Pierre's Warrior contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does this actually help with fatigue or energy?
The evidence doesn't support bovine liver for chronic fatigue syndrome — it's rated possibly ineffective. We don't have effectiveness data for bovine heart either, so we can't tell you it will boost your energy.
Is it safe if I'm pregnant or breastfeeding?
If you're pregnant, avoid it unless your doctor tells you otherwise — bovine liver contains very high vitamin A, which could harm a developing baby. For breastfeeding, safety hasn't been well studied, so talk with your doctor or pharmacist for personalized advice.
What's the concern about contamination?
Liver extract comes from raw animal liver from slaughterhouses, possibly from sick animals. There's also a theoretical risk of BSE (mad cow disease) contamination if the liver came from certain countries where BSE has been reported, though no human cases from liver extract have ever happened. Check the label to see where the product sources its liver.
Can I take this if I'm on a blood thinner like warfarin?
Liver extract contains vitamin K, which could reduce how well warfarin works by lowering your INR. The effect hasn't been directly studied, but it's a real concern — definitely run this by your pharmacist before starting.
What if I'm already taking iron supplements?
Bovine liver contains heme iron, so combining it with iron supplements could push your total iron intake too high. This raises the risk of stomach problems or iron buildup, especially over time or at high doses. Check with your pharmacist first.
