I had a severe vitamin D deficiency... I searched for a product without soy in it, due to my allergies. Finally found your combo oil, which brought my numbers up, but caused digestive upset (several digestive tract issues). When I switched to your capsules, the stomach upset ceased (at least from the vitamins). Due to autoimmune issues I need to take vitamin D at 10,000 iu, for life. So, I am very grateful I found you and your products.
