Question: I listened to the "truth" series and learned so much that helped me really understand what my body needed to be healthy. You really dispelled some important myths for me. It was a real relief to know I didn't need as much protein as I'd been taught. Everything you said helped me understand why I felt worse when I was eating the way Dr. Perricone suggests...high protein, loads of fish oil. I ordered two supplements you suggested. I like the probiotic. I ordered the ISO D3 too. I have to say I do not feel my best when I take it and I wonder if it has something to do with the soy. I was really curious why you chose this D3 when soy is such a common allergen. I'd love to hear your thoughts. Thanks for sharing your knowledge. Kyla
Answer: Hello Kyla,
The Isoflavones in Iso-D3 are indeed derived from soy, but are NOT the protein component nor are they the fat component of the soy bean. They are from the family of bioflavonoids - substances that are not considered allergenic or detrimental as soy protein and oil are. These isoflavones are probably the most beneficial components of the legume (beans) family. Metagenics are very aware of the soy allergy issue, and any allergenic substance are carefully removed. However, in cases of severe soy sensitivity it might be wise to observe your symptoms as they relate to ingestion of the product (Iso-D3) or to eliminating it for a few days, just to be certain. If it causes any reaction (very rare!), I would recommend to take it for 2-3 days of every week (at higher doses), then giving the immune system a break for 4-5 days, repeating this cycle weekly. This can be modified according to any changes in reactivity that might occur, if any.
At the worst case scenario, we have a very good alternative form of D3 that is fish-oil derived (certified pure of toxins), if that is an option you would not mind. I personally don't like fish oil for various reasons, but some people don't find it offensive in such a small amount.
Sincerely, Dr. T.
