Threonine. Necessary for the synthesis of collagen and immunoglobulins. Deficiency results in weak immunity and digestive disorders. Prescribed for digestive issues and weakened immunity.

Lysine. Important for growth, immunity, and calcium absorption. Deficiency leads to herpes, weakness, and slow recovery. Used for herpes, stress, and to accelerate tissue regeneration.

Valin. Amino acid BCAA nourishes muscles and improves recovery. In case of deficiency - fatigue, muscle weakness. It is prescribed during physical exertion for muscle growth.

Isoleucine. BCAA amino acid regulates sugar and restores muscles. Deficiency - dizziness, weakness, low endurance. Used during workouts, diabetes, and after injuries.

Zeaxanthin. Concentrates in the retina, protects against UV and blue light. In case of deficiency - deterioration of vision, increased risk of macular degeneration. Used for the prevention of age-related retinal degeneration and for protecting the eyes from screens.

Resveratrol. Antioxidant, slows down cell aging. In case of deficiency (in diet) — increased oxidative stress. Prescribed for inflammations, cardiovascular diseases, to protect blood vessels and promote longevity.

Melatonin. Sleep hormone, regulates biorhythms, restores immunity. Deficiency - insomnia, fatigue, disruption of circadian rhythms. Used for sleep disorders, shifting time zones, immune system disorders.

L-carnitine. Transports fatty acids into the mitochondria, increases energy production. In case of deficiency - fatigue, obesity, muscle weakness. Prescribed for obesity, physical exertion, cardiac problems.

Caffeine. Stimulates the CNS, increases alertness, concentration, and endurance. When lacking in the diet - fatigue (in those accustomed). Used to boost energy, sports goals, and eliminate drowsiness.

Berberine. Alkaloid with antimicrobial and hypoglycemic effects. Used in type 2 diabetes, obesity, to lower cholesterol and inflammation.

Betaine. Participates in the methylation and protection of the liver, regulates homocysteine. Deficiency leads to fatty liver infiltration and increased homocysteine. It is prescribed for fatty liver disease, metabolic disorders, and methionine deficiency.

Curcumin. Powerful anti-inflammatory action. Used for chronic inflammation, gastrointestinal disorders, and joint diseases.

Glutathione. The main antioxidant of cells, involved in detoxification and restoration. Deficiency leads to rapid fatigue, oxidative stress, frequent illnesses. Used in cases of intoxication, aging, autoimmune and chronic diseases.

Cholesterol. Builds cell membranes and hormones, necessary for the brain and vitamin D. In case of deficiency - depression, hormonal disorders, weakness. Used as dietary support for low levels of steroid hormones.

Phytoestrogens. Plant compounds that mimic the action of estrogens. When there is a deficiency, symptoms (hot flashes, osteoporosis) intensify in women during menopause. They are prescribed for menopause, hormonal imbalance, and the prevention of osteoporosis.
