What is the difference between vitamin D2 and vitamin D3?
Vitamin D2, also known as ergocalciferol, is found in plant-based foods. On the other hand, vitamin D3, or cholecalciferol, is more commonly found in animal produce. D3 is considered the preferred ingredient in vitamin D supplements as it has been found to be better at raising blood calcifediol levels, the main circulating form of vitamin D in the body.
Who would benefit from taking a vitamin D3 supplement?
Individuals who may benefit from taking a vitamin D3 supplement include vegetarians or those on a dairy-free diet, as D3 is primarily found in animal produce. Additionally, people living in countries with limited sunlight for extended periods, such as the UK, could benefit from an alternative source of vitamin D.
What are the side effects of a vitamin D deficiency?
A lack of vitamin D can have significant side effects, including adverse effects on bone, muscle, and tooth health. It is crucial for maintaining healthy bones and teeth and plays a vital role in supporting muscle function. Additionally, vitamin D is involved in cell division and contributes to the normal utilisation of calcium and phosphorus in the body.
Why is vitamin D3 recommended as a supplement?
Vitamin D3 is often recommended as a supplement because it helps raise levels of calcifediol, the main circulating form of vitamin D, more effectively than vitamin D2. Since many people obtain most of their vitamin D supply from sunlight, those living in regions with limited sun exposure for extended periods can benefit from vitamin D supplementation, especially during darker months. It is particularly important for vegetarians and individuals on dairy-free diets to ensure adequate vitamin D intake.
What should my vitamin D levels be?
The normal range of serum vitamin D is 30-50 ng/mL (75-125 nmol/L) or 40-60 ng/mL (100-150 nmol/L). The higher end has been shown to help improve athletic performance and reduce injury risk (REF).
Why does this Vitamin D Spray contain Vitamin K2?
