I just took one ALA capsule 400mg and it is making my throat burn and upsetting my stomach. Why is this happening? I ate first I had 2 cups skim milk, 1 banana, 2 cups juice, 8oz. chicken and 1 cup applesauce as my pre workout meal. I took it on a full stomach. I also had my multi-vitamin, vitamins E & C. Any reason for this. THANX.
