Yes, I cook the carrots and sweet potatoes lightly

I buy my supplements from
www.vitaminworld.com
I purchased the Vitamin B-Complex 50 and Vitamin E 400IU
The pitcairn book will tell you how much vitamin B-complex to give. It's a very small amount per day or you can put it in the recipe. I prefer to put it in the recipe. As far as the vitamin e, you can use one vitamin e 400IU for a whole recipe.
I don't use a multi-vitamin..It's not necessary when you use the healthy powder mix, vit e, and vit b-complex.
