Vitamin D Frequently Asked Questions
Where does our vitamin D come from?
Nutri Advanced use the cholecalciferol (vitamin D3) form of vitamin D which is the form your body makes in response to sunlight. This is sourced from sheep wool, also known as lanolin.
How long would I need to take vitamin D for?
Our body naturally makes large amounts of vitamin D when the skin is exposed to sunshine but living in the UK we tend not to get enough exposure. Therefore it is ideal to supplement with a maintenance dose of 1000-2000iu long term or especially between the months of October to March when our exposure to sunlight is low.
What are the signs and symptoms of vitamin D deficiency?
Typical symptoms include the following:
- muscle/joint pain and weakness
- tiredness or fatigue
- bone pain
To find out if you have a deficiency, a simple blood spot test can be carried out.
At what age should you start taking vitamin D?
Vitamin D can be taken from birth. Ensuring children get their daily requirement of vitamin D is imperative as deficiency can cause a condition called rickets.This is a condition that affects bone development in children causing the bones to become soft and weak, leading to bone deformities. The daily requirement for children is 400-600iu but the daily optimum is 1000iu.(1)
What other nutrients does vitamin D support?
Vitamin D works best alongside some other nutrients known as cofactors. The most important nutrients include magnesium, vitamin K, zinc, boron and vitamin A.
Which vitamin D supplement should I take?
Vitamin D as cholecalciferol (vitamin D3) is the best way to supplement as this is the form made by the body in response to sunlight.
Why do you include vitamin K in your supplements?
Vitamin D and vitamin K are two nutrients that work very closely together. Whereas vitamin D helps with calcium absorption, vitamin K is important in making sure that the calcium derived from food and supplements is used in the bones.
Is it vegetarian/vegan?
Vitamin D3 is certified vegetarian but not vegan as it is derived from sheep wool.
Is your Vitamin D range Kosher/Halal certified?
We do not hold Kosher/Halal certification for our vitamin D.
