Winter Supplement Guide: How to compensate for lack of sun, strengthen immunity and maintain energy. Recommendations specially adapted to Lithuania's climate.

In Lithuania, winter means: lack of sun (UVB rays are almost absent November-February), cold and damp weather (cold season), short days (seasonal fatigue, worse mood), fewer fresh local vegetables and fruits. For athletes this is a double blow — less vitamin D, weaker immunity and worse mood reduce motivation to exercise.

Vitamin D3 5000 TV + Vitamin C 2000 mg + Zinc 25 mg. This trio is the most powerful legal protection for the immune system. There is data on a 30-40% lower risk of colds.
Vitamin D3 + Omega-3 + Magnesium. All three substances are related to serotonin production and mood regulation. For mood support during the dark season.
B group vitamins in the morning + Creatine. B group participates in energy metabolism. Creatine improves brain function and reduces mental fatigue.
Creatine + Protein + Vitamin D3. In winter we naturally move less. Creatine helps maintain strength, protein — muscle mass, D3 — testosterone level.
