Vitamin A + D3 Alkaloid

Vitamin A + D3®


1 capsule contains:

  • Vitamin A (in the form of retinyl palmitate) – 500 µg (1667 IU);
  • Vutamin D3 (cholecalciferol) – 10 μg (400 IU).

Vitamin A helps maintain the skin and mucous membrane healthy, it is essential for good vision and the normal function of the immune system.

Vitamin D helps regulate the absorption/use of calcium and phosphorous; it helps maintain healthy bones and normal muscle function. Vitamin D deficiency may cause osteomalacia ( weak bones) in adults and osteoporosis in elderly persons.

Vitamin D helps regulate the normal concentration of calcium in blood and keeps teeth healthy. It also contributes to the normal function of the immune system.

Vitamin D is essential for normal growth and development of bones in children.

Vitamin D acquires hormonal activity when cholecalciferol (Vitamin D3) is converted into 1.25 dihydroxyvitamin D3 (calcitriol) in the liver and the kidneys. Vitamin D3 is the only vitamin in the body which can be produced by exposing the skin to sunlight (UVB). Yet, the modern lifestyle – spending long hours indoors along with the widespread use of sun-protection products result in deficiency in 1.25 dihydroxyvitamin D3, essential for bone building and immune system boosting.


Alkaloid’s Vitamin A+D3 capsules are used as dietary supplements for children and adults with increased need for these vitamins.
