Heart & Spleen Benefits

Beef heart is an excellent source of most B vitamins, as well as phosphorus, potassium and zinc. Additionally, beef heart is loaded with anserine, carnosine and taurine, all of which support the immune system, enhance blood flow and promote cardiovascular health.

Heart is also rich in coenzyme Q10 and l-carnitine, which improve energy, mitochondrial function, blood sugar regulation and insulin sensitivity.

Beef spleen is the best source of highly-absorbable heme-iron, making it the perfect food for people with iron deficiency or anemia.* Additionally, spleen is an excellent source of Vitamin C, selenium and peptides (including splenin, tuftsin and splenopentin) that help boost your immune system.

MK Supplements Heart & Spleen - Features

Why Beef Heart & Spleen

Heart and spleen are among the most nutrient-dense foods on the planet, and something our ancestors and early humans ate regularly for millions of years. 

MK Supplements' Grass-Fed Beef Heart & Spleen is from 100% pasture-raised New Zealand cattle. Unlike other manufacturers, we use a gentle freeze-drying method (instead of heat) to turn fresh organs into a powder before filling it into gelatin capsules.

Additionally, we don't use hexane or other harsh chemicals to defat our organ meats.

Instead, you get what we consider nature's ultimate multivitamin: a high-quality supplement that offers all the benefits of consuming fresh, grass-fed organ meat (without the strong taste).

  • Instructions

    Take four capsules per day, or up to eight capsules per day if you suffer from severe micronutrient deficiencies or have increased nutritional requirements (e.g., due to your active lifestyle). Children can take two capsules per day, depending on their weight. Consistent and long-term use produces the best results. Ask us if you need help determining the right dosage.

  • Benefits

    Heart & Spleen is a foundational supplement for any diet or health status, helping to fill nutritional gaps and improve energy, mood, exercise performance, libido and more.

  • Dosage Matters!

    We offer Heart & Speen and Grass-Fed Beef Liver as separate products (rather than combining them into a single capsule) to ensure that every dose contains a sufficient amount of organ meat. When taken together, these two supplements provide an ideal supply of the key nutrients that many Americans are deficient in, such as Vitamin A (retinol), Vitamin B12 and iron. 

  • Quality

    All of our supplements are rigorously tested for purity and heavy metals by third-party labs. Here's a copy of the test report of our latest batch. If you have questions about it, please let us know.

  • Ingredients

    All of our supplements are 100% free of additives, allergens, antibiotics, hormones, GMOs and pesticides. They’re freeze-dried and non-defatted to provide pure nose-to-tail nourishment for you and your family.

Heart & Spleen’s diverse micronutrient profile provides the building blocks for a wide range of bodily functions, supporting the metabolism, immune system, brain, reproductive organs, mental health and more.

  • Important Note

    Many synthetic multivitamin supplements contain significantly higher concentrations of vitamins and minerals. That's because your body doesn't absorb most of those nutrients due to their poor bioavailability. However, the nutrients in freeze-dried organ meats are highly absorbable, so you don't need excessive amounts. Additionally, it's virtually impossible to overdose on nutrients from real-food sources. So don't worry about getting a little more Vitamin A or iron than your body may need.
