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!

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.

I have tried so many things for a peaceful night’s rest. And while most can get me to fall asleep quickly, none have helped me to stay asleep. This supplement has done that for me after two weeks. I make sure to take two in the morning for clarity and two at night before bed. I’m very happy with this company. I also take their Huperzine capsules which has been life changing for me in terms of memory and focus. Also great for lucid dreaming.The only reason I’m giving 4 stars instead of five is because I find the 2000mg label to be misleading. The dosage is 4 capsules. This makes the potency exactly the same as every other brand available. Someone in another review wrote that he was happy to find this in a higher dose. That’s not actually true. Serving sizes for the other brands are 1 capsule.

Good product

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

Great 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."

I ordered this product because Dr. Sanjay Gupta recommends it in his book, "Keep Sharp," as being shown in current scientific research as promising for helping with mental acuity as one ages. He also characterizes it as being safe and very affordable, unlike many other products making similar claims currently on the market, So I thought, why not? Based on my experience with his journalism for CNN and his books on health issues, I trust Sanjay Gupta to be scientifically knowledgeable, honest, and veryconcerned with our nation's well-being. My experience with this product is very good; no adverse effects, and I feel quite sharp mentally, which is my main motive for taking it. I think anyone with similar concerns might well want to give it a try and stay tuned for ongoing research reports on its effectiveness and general outcomes.
