Hi Rich, Have the methylation protocol supplements changed from the ones offered on the Prohealth site? see link.. https://www.prohealth.com/shop/product.cfm/product__code/PHK39 I wanted to order them here on the Prohealth site, but I wanted to make sure these are the right supplements for the current protocol. I know that the Phosphatidyl Serine can be ordered separately since it is not included in the 4 pack above. I am asking because I read on another site that the following is the current protocol?.... 1. General Vitamin Neurological Health Formula : Start with ¼ tablet and increase dosage as tolerated to 2 tablets daily 2. Hydroxy B12 Mega Drops : 2 drops under the tongue daily 3. MethylMate B : 3 drops under the tongue daily 4. Folinic acid : ¼ capsule daily 5. Phosphatidyl Serine Complex : 1 softgel capsule daily (or lecithin) Thanks, I appreciate your help!!!
