Vitamin B6 (pyridoxine). Protein metabolism, brain function. Insufficiency leads to irritability, depression, anemia, weak immunity.

Vitamin B5 (pantothenic acid). Metabolism of fats, proteins, and carbohydrates. In case of deficiency: fatigue, depression, skin problems.

Vitamin B3 (niacin, nicotinic acid). Exchange of fats and carbohydrates, support of the nervous system. In case of deficiency, pellagra (dermatitis, diarrhea, and dementia).

Vitamin B2 (riboflavin). Energy production, skin health, vision, and metabolism. Insufficient levels lead to cracks in the corners of the mouth, dry skin, and light sensitivity.

Vitamin B1 (thiamine). Carbohydrate metabolism and maintenance of the nervous system. In case of deficiency, the disease beriberi, weakness, disturbances in the functioning of the heart and nervous system.

Sulfur. Synthesis of amino acids, collagen, and detoxification. A deficiency leads to problems with skin, joints, and delayed healing.

Pyrrolysine. A rare amino acid found in bacteria, involved in methane metabolism. It is not used for therapeutic purposes.

Selenocysteine. It is part of antioxidant enzymes, important for the thyroid gland and cell protection. In case of deficiency - increased fatigue, weakness, thyroid function disorders. Used in selenium deficiency, for immune support and antioxidant protection.

Cysteine. Contains sulfur, participates in the synthesis of glutathione, collagen, and detoxification. A deficiency leads to brittle hair, weakened immunity, and poor skin. Prescribed for intoxications, skin problems, and for hair and nail growth.

Arginine. Participates in the synthesis of nitric oxide, improves circulation and immunity. In case of deficiency — weakness, decreased libido, slow wound healing. Used for erectile dysfunction, vascular diseases, and to stimulate immunity.

Tyrosine. Precursor of dopamine, norepinephrine, and thyroxine, improves focus and mood. Deficiency leads to fatigue, depression, and decreased concentration. Taken during stress, depression, and reduced thyroid function.

Serin. Participates in the synthesis of DNA, phospholipids, important for the immune and nervous systems. Deficiency leads to decreased cognitive function and weakened immunity. Used to improve memory and in neurological disorders.

Proline. Key component of collagen, important for skin, joints, and blood vessels. Deficiency leads to weakness of connective tissue and slow healing. It is prescribed to improve the condition of the skin, joints, and in cases of osteoarthritis.

Glycine. Brake neurotransmitter, improves sleep, calms, protects the liver. In case of deficiency - irritability, insomnia, memory impairment. Used in cases of stress, sleep disorders, and intoxications.

Glutamic acid. Exciting neurotransmitter, involved in memory and learning. Deficiency leads to decreased cognitive function and fatigue. Used for fatigue and neurological disorders.

Glutamine. Nutrition for immune and intestinal cells, accelerates recovery. In case of deficiency - weak immunity, gastrointestinal problems. Prescribed after injuries, in case of ulcers, and in the syndrome of increased intestinal permeability.

Aspartic acid. Participates in DNA synthesis, energy production, and urea formation. Deficiency leads to fatigue and decreased mental activity. Used to enhance endurance and during mental strain.

Asparagine. Supports nitrogen balance and CNS function. Deficiency - irritability, weakness, metabolic disturbances. Used during mental exertion, stress, and physical exhaustion.

Alanine. Participates in glucose metabolism and energy exchange. A deficiency results in reduced energy and muscle weakness. Used during exertion, diabetes, and for muscle support.

Histidine. Involved in the synthesis of histamine, tissue healing, and growth. Deficiency leads to anemia, weakness, and skin issues. Used in cases of anemia, allergies, and peptic ulcers.
