What is Swanson's Vitamin D3 1000 IU?

Vitamin D3 1000 IU from Swanson is a dietary supplement in capsules based on cholecalciferol (Vitamin D3), the most valued form of vitamin D.

Features of Vitamin D

Vitamin D is the sunshine vitamin, since our body can synthesize it from skin exposure to the sun’s ultraviolet radiation.

However, in countries away from the equator, the amount of radiation received is not enough to meet daily vitamin needs, making it an essential vitamin.

Vitamin D deficiency leads to the development of rickets, osteomalacia, and disruptions in the normal functioning of the immune system.

Vitamin D helps with:

  •  The normal absorption and use of calcium and phosphorus.
  •  The maintenance of normal calcium levels in the blood.
  •  The normal functioning of muscles.
  •  The maintenance of teeth in normal conditions.
  •  The normal functioning of the immune system.
  •  The process of cell division.

Vitamin D helps maintain bones in normal conditions.

Why buy Swanson’s Vitamin D3?

Vitamin D insufficiency is very common in Europe and worldwide, reaching levels of up to 40% in Europe.

Supplementing with vitamin D3, especially in winter, or when work or study limits skin exposure to the sun for most of the day, is important.

Swanson’s Vitamin D3 1000 IU provides a high concentration of Vitamin D that covers daily vitamin needs.

Who is it for?

  •  People who eat little oily fish and have low sun exposure. 
  •  Everyone except during summer season.
