A Chinese Proverb says "Eat the organ you want to heal."
As such, the list below highlights the notable attributes of each organ (in alphabetical order):
ADRENALS are the one to go to if you are chronically fatigued. Following the like for like, this offal can help support your adrenal glands. We recommend eating it with a source of vitamin A like liver, and then it will support your body’s healthy adrenal hormone production.
BONE MARROW is incredibly nourishing with benefits including building immunity, repairing wounds, helping with digestion and even fighting cancer. Along with liver, bone marrow is one of the best offal to launch your organ journey! It is an amazing food to build health, especially during pregnancy.
Mothers-to-be will benefit greatly from its easy-to-digest and absorb, concentrated nourishment.
It contains many fat-soluble vitamins missing from most people's diets, such as vitamin K2 (as MK-4), vitamin A, omega-3, and amino acids like glycine, proline, and hydroxyproline. It also contains hyaluronic acid (well known in the beauty industry) and glycosaminoglycans.
Bone marrow also contains collagen. In the bone marrow, collagen provides structural support to the cells that produce blood cells and helps to maintain the strength and elasticity of the bones.
HEART is one of the richest sources of CoEnzyme Q10 (CoQ10), a nutritional powerhouse for the mitochondria. It is rich in B1 (thiamine), B2, B3, B12, copper, niacin, zinc, and iron. Heart also contains twice as much collagen and elastin than other muscle meat (therefore it is rich in the amino acids glycine and proline), which are essential for connective tissue health, joint health and digestive health
Heart is great for energy and endurance, as well as the heart in general.
KIDNEY is extremely high in vitamin B12. A 3 oz slice yields more than 10 times the daily requirement. Kidney is the best organ for omega-3’s. It is also high in selenium, iron, copper, zinc, and the enzyme DAO.
DAO is an enzyme that helps break down excess histamine in the body, therefore, kidney is highly recommended for those who suffer from symptoms related to the overproduction of histamine.
Kidney is the best known food source of selenium, an essential mineral we must get through our diet.
LIVER is the earth’s original (and most superior) multi-vitamin. It is known to be one of the most concentrated sources of vitamin A of any food. It is a great source of vitamins D, E, K, B2 (riboflavin), B3 (niacin), B7 (biotin) B9 (folate), B12, C, zinc, copper, phosphorus, selenium, iron and manganese. In terms of variety and density of micronutrients, no other whole food stacks up. The nutrients in liver are the most bioavailable.
Liver is one of the few dietary sources of bioavailable vitamin K2 (not to be confused with K1, the much less bioavailable plant-based version) and hyaluronic acid. Getting sufficient amounts of vitamin K2 is important for calcium absorption.
Like heart, liver is also a rich source of coenzyme Q10 (CoQ10), an important antioxidant that can help improve mitochondrial function, promote healthy aging and longevity, and improve brain and heart health.
PANCREAS is high in phosphorus, vitamins B2, B5 & B12.
It is also rich in enzymes which help to digest and break down fats, proteins, and carbohydrates.
If you suffer from digestive issues, pancreas is one to try!
SPLEEN is the organ richest in heme-iron, the most well absorbed form. It has 5x more heme iron than liver! Aside from iron, spleen is a great source of vitamins B3 & B12, and vitamin C. Also pantothenic acid, potassium and zinc.
Spleen is supportive for allergies, immune and blood deficiencies.
TESTICLES are a good source of zinc which helps support a healthy level of testosterone. If you feel like your libido needs bolstering, try testicles! Not only that, zinc also supports your reproductive system, immune system and helps your thyroid and metabolism function properly.
THYMUS is a good source of protein, vitamins B5 & B12, pantothenic acid, phosphorus and selenium, and a very good source of vitamin C. It is also one of the better organs for vitamin E.
Thymus stimulates the production, maturation and activation of T-cells, a type of white blood cell. Therefore, it is recommended for a healthy immune system.
