I found the pure prgnenalone powder through recommendations on this forum which is on the site ark of wellness. I noticed a big difference in th quality and I can manipulate the dosage easier. I only take it with a meal at breakfast or at least before noon. I've had only positive experiences with it like j. and I am a middle age female. Long Natural Health carries pregnenalone in capsule form with rice starch as the only additive. Apparently I should consider looking into the life extensions vitamin k though. I didn't mean to give you bad advice and I have been taking it for months with seemingly no problems.
