Heart & Soil is an animal organ supplement brand. The company claims to sell “The Most Nutrient Rich Supplements On The Planet,” and that their supplements are sourced exclusively from grass-fed animals.

But are organ meat supplements actually healthy, or are these just marketing claims? Are grass-fed animal products healthier than conventionally-raised? Do Heart & Soil supplements contain any questionable additive ingredients? And how do real users rate and describe the effects of these supplements?

In this article we’ll answer all of these questions and more as we analyze the ingredients in Heart & Soil supplements based on medical studies to give our take on whether or not they’re likely to be healthy.

Ingredient Analysis

The ingredients in Heart & Soil’s Warrior supplement are shown above.

Grass-fed heart and grass-fed liver sourced from cattle are the two active ingredients.

Organ meat is nutritionally rich, and may prevent nutritional deficiencies that are common even in high-income countries. A 2023 medical review documented that organ meats are rich in vitamin A, vitamin b12, iron, zinc, folate, selenium, choline and essential fatty acids.

Animal products sourced from grass-fed animals tend to be more nutritionally complete than animal products sourced from conventionally-raised animals, as we documented in our article on is Muscle Milk good for you.

Large-scale studies have presented some potential concerns about organ meat consumption.

A meta-study published in the European Journal of Epidemiology reported an association between organ meat consumption and bladder cancer risk.

High organ meat consumption was associated with increased risk of non-alcoholic fatty liver disease (NAFLD) in a 2023 population study.

We’re not suggesting that organ meat causes these health issues. These are just associations, but they may be worth speaking with a doctor about prior to regularly consuming organ meat.

The only inactive ingredient in Heart & Soil is gelatin, which is non-toxic and safe.

Overall, we consider Heart & Soil to have a clean formulation, and likely to have more pros than cons for the average American consumer.

The brand’s supplements are also Informed Sport Certified, which ensures a lack of contaminants and label accuracy.

The fact that Heart & Soil uses exclusively grass-fed animal organs and has this third-party certification makes the brand healthier than the majority of organ meat supplements in our opinion.

We Tried Heart & Soil Ourselves

As the author of this article, I wanted to try Heart & Soil supplements myself to share my thoughts on their effects.

I generally try to eat grass-fed animal organs at least once a month, but often forget to, and it had been nearly a year since I last ate organs when I got this supplement.

The convenience alone is a major plus for those (like me) who try to eat organs for the health benefits but dislike the taste.

The pills themselves are slightly larger than average, and you have to take six for a serving. This is no problem for me but it may pose a problem for older individuals.

I noticed a slight improvement in energy levels when taking this supplement, but I don't really consume organs to "feel" anything specific; just to support optimal health.

Overall, I may purchase Heart & Soil Beef Organs again and I'd rate the supplement 8/10. 

Questionable Health Claims

There are a number of questionable and uncited health claims on the Heart & Soil website.

The brand suggests that their “Firestarter” supplement can “Spark Your Weight Loss”:

The only active ingredient in this supplement is bovine kidney fat, and there is no explanation for how eating kidney fat would “spark” weight loss, nor is there any research citation proving such.

Heart & Soul suggests that their “Whole Package” supplement can improve blood flow and reproductive health in men:

There is no citation for either of these claims.

At the time of publishing this article, we can’t locate any clinical trials on any Heart & Soil supplements, so we don’t understand how the brand can make specific health claims given that most of their formulations are proprietary.

Customers Rate Heart & Soil

Amazon is a better resource for honest customer reviews than a brand’s website in our opinion.

Bone Matrix is the only Heart & Soil supplement currently sold on Amazon. It’s been reviewed over 190 times with an average customer review rating of 4.7 out of 5 stars.

The top positive review from a verified purchaser comes from a user named “Alex L” who gives the supplement a 5/5 star rating and claims it improved athletic endurance:

“My bones haven't been the strongest and my doctor says I have to get more calcium…The past year I've felt discomfort during these long hikes in my joints so I looked for something that could supplement my joints and bones. With this, I've already been feeling better on my long hikes and I feel stronger which is the best part. I take a few of these a day now and so far I've had no problems! I highly recommend it.”

The top negative review is from a user who gave the product a 1/5 star rating without leaving a comment.

Heart & Soil has a 4.5 out of 5 star rating on Facebook.

Conclusion

In the category of organ meat supplements, we consider this brand to be one of the best options because of its sourcing, certification and clean formulations free of unhealthy additives.

Most of the customer reviews we came across while researching this article were positive.

Buying whole organ meat and cooking at home may be cheaper per-gram than buying Heart & Soil, and in this article we included several organ meat cooking recipes.

There are several uncited and questionable health claims on the Heart & Soil website, including the suggestion that one of the supplements sold by the brand causes weight loss.

Meta-studies on organ meat consumption and health are mixed, but this is a type of food that has been consumed for centuries and is known to be nutritionally rich.
