VITAMIN F

Vitamin F - antiholesterinovy ​​vitamin (unsaturated fatty acids linoleic, linolenic and arachidonic) - a fat-soluble vitamin, is composed of unsaturated fatty acids derived from food. Vitamin F in the scientific and patent literature, brochures and technical documentation called lipid formulations containing essential fatty acids, particularly gamma-linolenic acids.

Leaving polyunsaturated fatty acids traditional name "vitamin", they should be, from the biochemical and pharmacological point of view, be identified as a group of biologically active compounds with a paravitaminnym and paragormonalnym action. , In favor of their ability to say when administered to eliminate avitaminozopodobnye phenomenon. In favor paragormonalnogo actions of polyunsaturated fatty acids in the presence of the enzyme prostaglandinsintetazy demonstrates the ability to transform into prostaglandins, leukotrienes, thromboxanes, and other powerful intracellular mediators of hormonal effects.

• The biological role of vitamin F
  Unsaturated linoleic acid type are essential for the body. In the evolution of the body dramatically decreased ability to convert linoleic acid commonly found in vegetable fats, in gamma-linolenic, so the gamma-linolenic acid is an essential and must come from food or in food supplements.

  Gamma-linolenic acid (GLA) - polyunsaturated fatty acid linoleic type belonging to the family of omega - 6 as the first double bond is at her sixth carbon from the methyl end. Gamma-linolenic acid, as well as other polyunsaturated fatty acids, is an energy substrate in the process of breathing and the intracellular part of the phospholipid membranes of animal cells. With a lack of food it is a violation of the functioning of biological membranes and lipid metabolism in tissues, leading to the development of pathological processes, such as dermatitis, liver disease, atherosclerosis develops.

  Vitamin F oblabaet antiallergic properties. Gamma-linolenic acid can be transformed through the dihomo-gamma-linolenic acid to prostaglandin E1. It is known that prostaglandins E1 inhibit the first phase of the release of histamine, such as granules of mast cells, and cropped allergic bronchoconstriction induced by histamine, and also have a warning sensitization effect as inhibitors of histamine.

  Functions of Vitamin F:

  • Involved in the synthesis of fat (especially saturated fat), cholesterol metabolism.
  • Anti-inflammatory and antihistamine effects.
  • Effect on spermatogenesis.
  • Of prostaglandins.
  • Stimulation of the immune defense.
  • Wound healing.
  • In close cooperation with vitamin D promotes the assimilation of calcium and phosphorus, which is essential for bone tissue.
   

• Metabolism of vitamin F
  Essential fatty acids are absorbed in the small intestine, as well as other fatty acids, and are transported in the chylomicrons to the authorities. The tissues are used to form the most important lipids contained in biological membranes and have a regulatory activity. The metabolism of their double bonds restored.

  If linoleic acid in the body is enough, two other fatty acids can be synthesized. Excessive carbohydrate intake increases the need for vitamin F.

  The body stores this vitamin in the heart, liver, kidneys, brain, blood, and muscle.
   

• Symptoms of vitamin F
  The most common deficiency of vitamin F manifests itself in early childhood education (for children up to one year), which may be due to insufficient intake of the diet, malabsorption and infectious diseases. Clinic hypovitaminosis in children manifests retarded growth, weight loss, peeling skin, thickening of the epidermis, the increase in water consumption by reducing urine output, loose stool.In adults, also noted the suppression of reproductive function, cardiovascular and infectious diseases. There may be diseases of the skin (especially eczema), hair, brittle nails, acne.
   

• Indications for use of vitamin F
  • Different types of dermatitis (eczema - good results primrose oil treatment, seborrhea, acne, cracked, including anal).
  • Eczema in babies.
  • Allergic diseases.
  • Autoimmune inflammatory diseases.
  • Prevention of phlebitis.
  • Diabetes.
  • Lipid disorders.
   

• Symptoms of overdose of vitamin F
  Toxicity in vitamin F not, but excessive intake can lead to weight gain.

  You should not omega-3 fatty acids, as they have property they thin the blood and can cause bleeding.

  Hypervitaminosis of vitamin F manifested by pains in the stomach, heartburn, skin rashes, allergic and is associated with an overdose of unsaturated fatty acids.

  An excess of omega-6 fatty acids interfere with omega-3 to perform its role and is able to provoke such inflammation, like asthma or arthritis.
   

• The need for vitamin F
  Daily vitamin F is measured in milligrams. The daily requirement for vitamin F for adults is about 1000 m g, corresponding to 20-30 g of vegetable oil.
   

• Food sources of vitamin F
  The best natural sources: Vegetable oils from the ovary wheat, linseed, sunflower, safflower, soybean, peanut, almond, avocado, oatmeal, corn, brown rice, nuts. Twelve teaspoons of sunflower seeds or eighteen slices of pecan can cover the daily requirement for vitamin. All vegetable oils should be the first cold-pressed, unfiltered, nedezodorizovannye (ie kept their smell).
   

• Interaction and features
  Especially vitamin F - zhirorastvorim, very sensitive to light, heat and exposure to air, which causes the formation of toxic oxides and free radicals, and therefore for the protection of vitamin F should be taken with antioxidants (vitamin E, beta-carotene, and selenium).

  Its effect is enhanced with zinc and vitamins B6 and C.
