A natural, bioavailable vitamin D3
THERASCIENCE Laboratory has rigorously selected a bioavailable form of vitamin D3 for its superior absorption and assimilation in the body, in order to guarantee optimal efficacy.
The vitamin D used in our formulas is natural, present in cholecalciferol (D3) form, recognized for its bioavailability and optimal assimilation by the body. This is the form naturally produced by the skin under the action of UVB rays. This form stands out for its superior bioavailability compared to vitamin D2 (ergocalciferol). Vitamin D3 is fat-soluble, allowing it to be efficiently stored in the body and to maintain an optimal blood vitamin D level.
The vitamin D3 used in PHYSIOMANCE® D-Nat 1000 is produced from sheep’s wool, with lanolin, also known as « wool wax ». Vitamin D3 is obtained by exposing lanolin to UVB radiation with a wavelength similar to that of sunlight. This triggers a natural photochemical conversion reaction, similar to the one that occurs in our body, producing vitamin D crystals that no longer contain lanolin. As a result, the vitamin D thus obtained is perfectly natural and of high purity.
