LONG-LASTING SUPPLY: Limited sunlight can affect daily Vitamin D levels, especially during colder months or indoor lifestyles. Each tablet provides 4000IU of Vitamin D3, making it a practical option when natural sources of this vitamin are limited. Each bottle contains 400 vitamin D tablets, lasting for 14 months (1+ year supply). Just take 1 Vitamin D 4000IU tablet a day!
Cholecalciferol – A Widely Used Form of Vitamin D3: Vitamin D is naturally produced through biological processes in response to sunlight and is found in specific dietary sources such as oily fish, mushrooms, and eggs.

Sourced from Lanolin, cholecalciferol is a naturally occurring form of Vitamin D3 and is known for its bioavailability.
