Functions and diversity of vitamins

  1. In case of a disorder of the absorption of nutrients, the functioning of phase 2 of the liver should be improved. In addition, the stocks of antioxidants, such as vitamins A and C, must be replenished. In addition, vitamin supplementation is necessary of vitamins B2, B6 and B11 and include zinc, magnesium, molybdenum, manganese, taurine, glycine and carnitine. Most vitamins in supplements are synthetic, which means that they are precisely copied in a laboratory, partly for practical reasons. The disadvantage is that synthetic vitamin pills contain up to 90% pure filler and often have an absorption capacity of less than five percent. It is therefore much better to get a supplement of vitamins from food.


  1. Packaging of foods and nutritional supplements usually states the RDA (recommended daily amount). However, dosages are often higher in these supplements, which are available as tablets, capsules, powders, or drops. One does not get too much of most vitamins, which is why a higher dose is not uncommon. However, keep in mind that vitamins A, D, E and K are already partly stored in our adipose tissue. As a result, one should be more careful when supplementing with these vitamins at a high dose, because the body already (partially) meets the need.

Vitamin A

  1. This fat-soluble vitamin, also called retinol, produces the pigment rhodopsin, which allows us to see in the dark. It also ensures sufficient growth, stronger bones and healthy skin. This vitamin, as an antioxidant, also prevents damage to cell membranes and plays an important role in the prevention of cancer. Older people in particular need vitamin A in addition to vitamin D. Low vitamin A levels can be caused by a diet low in fats - mouth and ear infections. However, too much vitamin A is harmful to the liver. The active form of vitamin A is retinol.

Provitamin A

  1. This not yet complete vitamin, also called beta-carotene, protects the cells against free radicals as an antioxidant.

Vitamin B

  1. All B vitamins are water soluble, involved in the release of energy from food and have a function in the nervous system. Vitamin B11 also plays a role in the production and breakdown of homocysteine ​​in the body. Vitamin B6 is responsible for the transport of magnesium into the cell, so that it can be used for the production of ATP. Vitamin B3 is a precursor to NADH which, like ATP, is a form of energy storage. This vitamin colors the urine more yellow. It increases HDL and lowers triglyceride levels and total cholesterol. Vitamin B5 supports the adrenal glands in the production of (nor) adrenaline and the symptoms of deficiency are remarkably similar to those of ME and multiple allergies. Vitamin B1 plays a role in the formation of the hormone acetylcholine. Vitamin B2 is required for the normal combustion processes of the cells. Taking vitamin B6 in the morning converts tryptophan into serotonin. In case of a vitamin B12 deficiency, oxygen is not passed to the cells as well (sighs).

Vitamin C

  1. This water-soluble vitamin, also called ascorbic acid, helps white blood cells fight infection and is essential for proper wound healing. It is also good for the heart and helps in the absorption of iron and it can prevent cataracts when ingested 350 grams of vitamin C. Like the amino acids lysine and proline, it is not produced by the body and must therefore be present in food on a daily basis. Vitamin C is an indispensable factor in the formation of connective tissue. This vitamin is usually synthesized from corn syrup, sometimes from cane or beet sugar. A symbol of a vitamin C deficiency is fatigue.

Vitamin D

  1. This fat-soluble vitamin, also called calciferol or ergosterol, is formed from cholesterol and acts as a hormone and antioxidant. This substance is good for strong bones and to maintain muscle strength. It also helps to maintain resistance and is good for psoriasis patients. This vitamin is closely related to phosphorus (it prevents excessive secretion of it by the kidneys) and cholesterol. Older people need less vitamin D, but a high need for vitamin A. Most of the vitamin D that the body uses is formed under the skin by exposure to sunlight. Take vitamin D3 capsules with olive oil. Cod liver oil contains the correct ratio of vitamins A and D. To convert cholesterol into vitamin D, sufficient magnesium, vitamins A and K are needed, otherwise too much calcium will enter the blood, causing it to float in the blood. If calcium (calcium) is not processed properly you get weak bones. A vitamin D blood test (active form calcitriol) is a perfect blood test to determine if there is enough magnesium and calcium in the blood.

Vitamin E

  1. This fat-soluble vitamin, also called toceferol, increases the action of vitamin A in the body and, unlike the other fat-soluble vitamins, appears to be stored for only a short time. This vitamin, which is a manifestation of vitamin A, may slow the aging process and slow the development of mild Alzheimer's.

Vitamin F

  1. This non-official fat-soluble vitamin has evening primrose oil as an active ingredient and is also called efamol.

Vitamin H

  1. This water-soluble vitamin, also called biotin (vitamin B8), is necessary for various biochemical processes in the body.

Vitamin K

  1. This fat-soluble vitamin, also called phyllo (K1) or menaquinone (K2), is produced by bacteria in the colon. From there it is absorbed into the bloodstream through the wall to become one of the various blood clotting factors in the blood. Because the pancreas contains a high level of vitamin K, vitamin K may have to do with the control of blood sugar. According to a study conducted at the University of Maastricht, vitamin K2 is effective against cardiovascular diseases. It helps remove calcium from the blood vessels and joints and absorb calcium into the bones. In addition, according to another study, an adequate amount of vitamin K2 would reduce the risk of prostate cancer by 35%.

Influencing the absorption capacity of vitamins

  1. An increased absorption takes place through simultaneous supplementation of vitamin C and vegetable foods that contain iron. The same thing happens when you combine vitamin D and calcium in a meal. Viewed as a group, the B vitamins improve the absorption of each B vitamin individually and vitamins A, C and E appear to improve the absorption of selenium.
