Best Vitamin D3 is a food supplement with vitamin D3, cholecalciferol, in convenient drops. Every drop provides 1000 IU (25 µg) of vitamin D3, and the suggested serving is 2 drops a day after a meal.
The skin makes vitamin D when it is exposed to sunlight. In the UK, between October and early March the sun is not strong enough for that, which is why the NHS advises everyone to consider taking a daily vitamin D supplement during autumn and winter.
Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus and to normal blood calcium levels. It contributes to the maintenance of normal bones, teeth and muscle function, to the normal function of the immune system, and has a role in the process of cell division.
Vitamin D is fat-soluble, so it comes dissolved in oil with natural vitamin E as the antioxidant. A 30 ml bottle holds about 900 drops, which is 450 servings at 2 drops a day.
A balanced diet and a proper lifestyle remain what matters most. A food supplement is an addition to them, never a replacement.

Vitamin D is found in oily fish, eggs and fortified foods, and the skin makes it in summer sunlight. A varied diet is the foundation; a supplement can complement it.
Vitamin D3, cholecalciferol, is the same form of vitamin D that the skin produces in sunlight. In Best Vitamin D3 it comes from lanolin, the natural wax of sheep's wool.
Vitamin D does not dissolve in water, so it is supplied in oil. Natural vitamin E, tocopherol, is added as the antioxidant that protects the formula in the bottle.
Every drop contains 1000 IU, which is 25 µg of vitamin D3. The suggested serving is 2 drops a day after a meal, and the 30 ml bottle holds about 900 drops.
Best Vitamin D3 contains vitamin D3 alone, without vitamin K2 or other vitamins, so it is easy to combine with the rest of your routine. Check the labels of any other products you take so the total intake stays within the recommended servings.
Every batch of BestLab supplements is tested at J.S. Hamilton, an independent accredited laboratory, for microbiological purity, heavy metals and gluten.
