- THE JOURNEY OF WEIGHTWORLD: Born from a passion for food supplements, WeightWorld has been growing since 2006. With nearly two decades of experience, the brand offers a wide range of products, including vitamins, minerals, plant-based supplements, devices, and more. Now reaching multiple countries, the focus remains on developing products that evolve with changing needs while staying true to the values that started it all.
- CHOLECALCIFEROL – GENTLE 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. However, meeting daily requirements through sun exposure and diet alone can be challenging. Sourced from lanolin, cholecalciferol is a naturally occurring form of vitamin D3 known for its bioavailability.
- 400 TABLETS - 1+ YEAR SUPPLY: Limited sunlight can affect daily Vitamin D levels, especially during colder months or for those with predominantly indoor lifestyles. Each tablet provides 4000IU of Vitamin D3, making it a practical option when natural sources are limited. Each bottle contains 400 vitamin D tablets, lasting for 14 months (1+ year supply). Simply take 1 Vitamin D 4000IU tablet per day to suit a modern, busy lifestyle.
