L-Serine Capsules (Third Party Tested) - 2,000mg Servings Used in Clinical Study, 180 Count, 500mg per Capsule (L Serine Amino Acid for Serotonin Production and Brain Support) by Double Wood

At 66, I’m all about keeping my mind sharp, and these L-Serine capsules deliver. The 2,000mg servings make it easy to match clinical study doses, and I’ve noticed improved focus and mental clarity after a few weeks. Love that it’s third-party tested, so I trust the quality. Great choice for brain support and overall mental wellness!

Noticed especially better memory retention and thought process!! Very helpful!!

I have been using L-Serine for a few months, and I find it to be a quality product. I can say that I feel somewhat more “plugged in” to what is going on around me, and with others. Having read about the effects of L-Serine as an Alzheimer’s preventative medication, I will continue to rely on the product.The product seems to be working for me!

I am a 68 Year old woman, and I take a lot of supplements, some of them because I can actually feel the results (like magnesium for leg cramps or melatonin to help me sleep, etc., probiotics and krill for intestinal health), others because I am deficient (Vitamin D for one), and others because I have researched them and although you can't necessarily tell immediately, they have excellent effects (antioxidants keeping me well or helping me fight something coming on, others helping my digestion, or heart or brain health, etc.), and quite a few other supplements, like several for my arthritis and general inflammation.Nevertheless, for the past 2 years I have been waking up tired. I used to wake up energetic (despite being low thyroid, which is the only thing I take prescription medication for - T3 and T4) and ready to start the day. Not tired. So I have been searching for something to help change that. And of course, I was having what I assumed were typical memory issues that older people suffer with, like not being able to find the exact word I wanted, or the name of an actor I could picture, and so on.Doctors have been useless, and blood tests have not been helpful either. They say idiotic things like, well, now you are getting older . . . .So when I heard about L-Serine, I thought, well, I already take phosphatidylserine and pregnenolone, so I will research L-Serine. I checked out the research on the National Institute of Health, and liked the idea of a neuroprotector, and especially appealing was that they found it helps with sleep. I have an overactive bladder, and it's not terrible in the daytime, but at night I wake up about every 2 hours although I am usually able to get right back to sleep. But I have of late also been sleeping 9-10 hours. My Fitbit says less, I suppose because it is counting the time I am up. Still, it's a lot of lost time, at least to me.After taking two capsules twice daily for less than a week, I was AMAZED at my results! Suddenly, I could wake up after 7 or 7-1/2 hours WIDE AWAKE, no longer tired, thinking about going back to sleep and begrudgingly staying up after nine or ten hours in (and out of) bed. I am absolutely ecstatic.It has been 2 weeks now, and I am still thrilled, and expect to continue taking this supplement. THANK YOU DOUBLE WOOD!!I am a purchaser of this product, did not receive it free. And this is a legitimate review from a customer unaffiliated with the company.

This has been one of my favorite hacks, 2 capsules before bed. I find I sleep consistently and all through the night instead of occasionally waking up and having trouble falling back in the middle of the night

IT IS A QUALITY PRODUCT!

Reports are coming out that suggest more research is needed before this supplement should be considered safe."We are trying to say, be cautious," said lead researcher Xu Chen, an Alzheimer's disease researcher and assistant professor of neuroscience at the University of California, San Diego. "If you're trying to prevent Alzheimer's disease or cognitive decline during aging, serine might not help you and, in fact, might be doing something bad."

Very happy with this product. My husband's memory has improved. My mother, who is 90, has absolutely started to remember more and has a better attention span in spite of increasing stress in her life due to my father's decline. I take it too, to make sure my memory stays intact.
