  • All Known Essential Minerals

    Minerals (nutrients) are inorganic substances (contain no carbon) that are necessary for normal body function and development.

    Macrominerals

    Macro-minerals are needed in large doses (approximate recommended daily intake, milligrams (mg) per day ): 

    1. potassium, K (3500 mg) - metal, ions are necessary for the function of all living cells; 
    2. chloride, Cl− (3400 mg) - essential electrolyte in all body fluids; 
    3. sodium, Na, natrium (2400 mg) - metal, essential for all animals and some plants;
    4. calcium, Ca (1000 mg) - metal, essential for living organisms, produced in supernova nucleosynthesis;
    5. phosphorus, P (1000 mg) - in the form of the phosphate is required for all known forms of life; 
    6. choline (425 - 550 mg) - essential vitamin-like (vitamin B4) nutrient, synthesized in human body, but not sufficiently;
    7. magnesium, Mg (350 mg) - metal, essential for all known living organisms;

    Trace Minerals

    Trace minerals are needed in very small amounts (recommended daily intake, milligrams (mg) or micrograms (mcg) per day: 

    1. iron, Fe (15 mg) - metal, found in nearly all living organisms;
    2. zinc, Zn (8 - 11 mg) - metal, essential for humans and other organisms;
    3. manganese, Mn (5 mg) - metal, toxic essential trace element;
    4. fluorineF, fluoride ion, F− (3 - 4 mg) - a beneficial poisonous element, essential for bone solidity;
    5. copper, Cu (2 mg) - metal, essential to all living organisms;
    6. iodine, I (150 mcg) - a key component of thyroid hormones;
    7. selenium, Se (35mcg) - toxic in large doses, essential micronutrient for animals;
    8. chromium, Cr (30 mcg) - chromium (III) is questionably essential for humans.

  • Choline Recommended Intake from Seeds and Fruits

    Choline is an essential vitamin-like (vitamin B4) nutrient, synthesized in human body, but not sufficiently.

    The recommended adequate intake (AI) of choline is set at 425 milligrams (mg)/day for women and 550 mg/day for men.

    Choline deficiency causes muscle damage and abnormal deposition of fat in the liver, which results in a condition called nonalcoholic fatty liver disease. Genetic predispositions and gender can influence individual variation in choline requirements.

Vitamin B12 Cobalamin

Vitamin B12, also called cobalamin, is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system, and the formation of red blood cells. It is involved in the metabolism of every cell of the human body, especially affecting DNA synthesis, fatty acid and amino acid metabolism.

No fungi, plants, nor animals (including humans) are capable of producing vitamin B12. Only bacteria and archaea have the enzymes needed for its synthesis. Proved food sources of B12 are animal products (meat, fish, dairy products). Some research states that certain non-animal products possibly can be a natural source of B12 because of bacterial symbiosis.

B12 is the largest and most structurally complicated vitamin and can be produced industrially only through a bacterial fermentation-synthesis. This synthetic B12 is used to fortify foods and sold as a dietary supplement.

Vitamin B12 consists of a class of chemically related compounds (vitamers), all of which show pharmacological activity. It contains the biochemically rare element cobalt (chemical symbol Co). The vitamer is produced by bacteria as hydroxocobalamin, but conversion between different forms of the vitamin occurs in the body after consumption

B12 aids in lowering homocysteine levels and may lower the risk of heart disease. 

Recommended daily amount: 2.4 mcg

Example sources: fortified cereals, doenjang and chunggukjang (fermented soybeans), nori (seaweed).
