If you have low immunity, it is important to take care of a proper diet, physical activity and general lifestyle. Strengthening immunity is an important aspect of health, so it is also worth consulting your doctor.

Vitamin C (ascorbic acid) and vitamin D3 are popular supplements that can help boost immunity. Here is some basic information about them:

Vitamin C (ascorbic acid): it is known for its antioxidant action, helps protect the body from cell damage. It can help increase the body's resistance to infections, shortening the duration of a cold or relieving its symptoms.

Ascorvita 1000 is a preparation containing 1000 mg of vitamin C per tablet, which is a relatively high dose, it should not be used long-term. Ascorvita MAX is a dietary supplement in the form of tablets, which contains vitamin C with the addition of vitamin D and zinc.

Vitamin D3 (cholecalciferol): is important for bone health, but also affects immune function. It helps in the absorption of calcium and keeping it in adequate amounts in the body, which is important for a healthy immune system. It can be especially beneficial during periods of exposure to sunlight deficiency because the body produces vitamin D in response to sun exposure. https://www.gdziepolek.pl/produkty/83622/vitrum-d3-forte-kapsulki/apteki
