    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.

    MK Supplements Hert & Spleen Nutrients

    Nutrients in Heart & Spleen (Per Serving)

    Jam-packed with valuable micronutrients like folate, heme-iron, riboflavin and Vitamin B12 (as well as many others), it's the perfect natural multivitamin.

    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. Plus, its synergistic combination of vitamins and minerals can naturally boost energy levels by supporting mitochondria (the part of every cell responsible for energy production).

    • 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.

    • Immune System

      Spleen-specific peptides (splenin, tuftsin and splenopentin) and heme-iron are critical for optimal immune function. Selenium is a cofactor for the body’s antioxidant defense (glutathione peroxidase, thioredoxin reductase).

    • Muscle Recovery

      The amino acids found in Heart & Spleen speed up muscle recovery after intense exercise.

    feel good

    I purchased 2 different products. with these 2 and another ***** product , I was taking all 3 every day. I started getting itchy. I took a few days off . Now I'm only taking 1 each day. I did love the energy the 3 doses gave me and I believe they we very integral to getting me off of my drug of choice ... carbs. I plan to take them forever.

    Bioavailable Nutrients - Heart & Spleen and Liver

    I'd been trying to move away from synthetic vitamins and minerals that are readily available in stores but terribly hard on the body to process when I came across MK Supplements. Knowing that I'm consuming a naturally nutrient-dense supplement that provides me with bioavailable vitamins and minerals my body can actually absorb is fantastic. It also feels good knowing that the company prides themselves on the quality of their products from start to finish, which is made obvious in the sourcing/processing of their supplements as well as their environmentally conscious packaging.

    I like the 45 day supply and glass bottle, this and liver are the multivitamin for me and my 12 and 14 year old boys. If you are a woman with heavy flow period, liver and spleen are going to help a lot with that highly recommended. Thank you MK!
