jenbooks, Thanks for the explanation. I will do some reading on it. P.s. do you know when jarrow will be carrying out the tocotrienol-complex without the glycine you mentioned before? I always notice remarkable anti-inflammatory effects from the product. I recently read something about tocotrienols inhibiting prostaglandin 2 or offsetting the 3 types of PG favoring 1 and 3. I have D6D impairment so it might be a good idea to start supplementing with it again.
