Review: thankful for such a cheap supplement that I get real results from! - Why did you pick this product vs others?: I was happy to find a 100mg tablet, most are higher. I split them in half to take 3-4 times a day as Dr Mercola suggests, as being water soluble it passes through quickly. There's been some studies casting some suspicion on higher doses, and these small tablets let me keep it low, and even cheaper. I split two tabs each morning, and leave them on the counter to easily take throughout the day. Since taking this my energy has evened out, and my drowsy afternoons leading to naps have pretty much stopped, I'm so relieved. I hope the mitochondrial and brain benefits are true, but regardless I'm seeing real results and will continue!
