Re: Is it better to take a Vit D supplement by itself or in a Multivitamin ?
Most multi's only have 200 to 400 IU of Vit D. Most people benefit more from taking 1000-5000 IU a day of Vit D. I take 5000 IU a day in D3. So I would say take it separate or in addition to your multi. Keep in mind that Vit D is a fat soluble vitamin, so it requires fat in order to be absorbed. For that reason, you should take it with food, ideally with your largest meal of the day because it will have the most fat.
