Where is your soy sourced for your products? Is it GMO or organic? Thank you.
Hi DCS. Thank you for your question. At present, we only have one product that is derived from soy. Phosphatidylserine was first introduced by prescription in Europe in the 1980's, and at that time I was reading many research papers about it. In the medical literature, in fact, I could find nothing that worked better for improving memory. Back then, the only source for phosphatidylserine was bovine, but the mad-cow epidemic changed all that. Since then, manufacturers have learned how to make phosphatidylserine from soy lecithin, and now nearly all PS products comes from highly refined extracts of soy lecithin. For most of those years, GMO soybeans did not even exist.
Nevertheless, the world continues to change, and we have been monitoring the GMO status of phosphatidylserine for some time, now. Although there have been assurances that no GMO proteins are present in soy derived phosphatidylserine (all proteins are removed in the purification process), we have not seen any certification, yet, that the soybean starting material is free of GMO's. Hence, the purification and testing that is conducted on the final product, phosphatidylserine, still seems to be the best safeguard against GMO's.
Even so, we do not wish to subsidize GMO practices in any way, and for this reason when Lidtke learned of the availability of phosphatidylserine derived from non-GMO sunflower, we took steps to acquire it. I have reviewed the claim that the sunflower lecithin (from which our soon-to-be-available phosphatidylserine is derived) is non-GMO, and we have now received the certification. The cost for this raw material is about 25% higher than for non-sunflower phosphatidylserine, but it should not add that much to the price of the finished product.
I estimate that our sunflower-derived product will be available in the next few weeks (February 2014) and you only need to specify the sunflower-source phosphatidylserine when ordering. If customers prefer the sunflower-derived formula, then we will offer it exclusively. Let me know if I can be of further help!
