Research-based product
When I was copyediting research articles for refereed neurology journals, I came across some research on curcummin. I consulted with a doctor and the doctor recommended Longvida, I did some background investigating and communicated via email with one of the original researchers on the team that developed Longvida. I am pleased with the product. Longvida is the only product that I have discovered that has been shown by peer-review research to be formulated to cross the blood-brain barrier (some other formulations use piperine, but I believe the the efficacy of this is questionable). All the fantastic claims made by distributors of non-Longvida curcummin are marketing hype because there is no hard research showing that the curcummin in the myriad of products out there crosses the blood-brain barrier. As a "side benefit," after starting on Longvida, I very quickly noticed a personal effect of "mood enhancement." Because I was not expecting anything of this sort from the product, I would eliminate "placebo effect" for this result. It was only after experiencing this that I looked into the possibility of such an effect resulting from curcummin. The reason I purchase the powder form of Longvida is that the standard dose of 500 mg per capsule supplied by every distributor that I have found is more that what the original research used, and, thus, the distributors are selling you more product than you need (and making more profit by doing so). The original researchers used 80 mg curcummin, for which you need 320 mg of the Longvida formulation and not 500 mg. Yes, I had to buy a scale, and, yes, it's a bit of a hassle to measure it out every day, but that's just who I am. I recommend Nootropics Longvida curcummin because they have the integrity to offer the most trustworthy formulation of curcummin in the form that allows me, the consumer, to determine my own dosage, even though Nootropics makes less profit in the bargain.
