Katie D My daughter and I take a vegan supplement which has 100% vit d in. Will we be taking too much vit d if we take this as well or do you have a dha supplement without vit d?
Vegetology Hi, the combined level of Vitamin D3 from taking both Opti3 and VegVit is 400iu. While that is twice the European Nutrition Reference Value (NRV) for Vitamin D (which is 200iu), many countries actually recommend 400iu and indeed many health professionals recommend much higher doses. The recognised upper safe limit for Vitamin D is 4000iu, so ten times the amount you will be taking.
