Premium L-Theanine, Alpha-GPC, Lion’s Mane & Phosphatidylserine – Cognitive & Mental Focus Support Supplement – Made in The USA – 150 Capsules

Why did you pick this product vs others?:This is an excellent product, and I primarily requested it for the theanine—which is fantastic for brain health. My main reason for using it, though, is how well it works alongside caffeine. The theanine really smooths out the typical side effects of caffeine, like jitteriness and nervousness.I take it with my preworkout during evening workouts, and it allows me to enjoy all the performance benefits of caffeine without the shakiness. Surprisingly, it also helps me wind down afterward and get a restful night’s sleep.This formula also includes alpha-GPC (a source of choline), which supports cognitive function, and lion’s mane, known for promoting focus and mood balance. Together, these ingredients help me stay mentally sharp during workouts and think more clearly throughout the session.Overall, it’s a well-rounded supplement for anyone looking to boost mental clarity, improve workout performance, and reduce caffeine-related side effects.

I really like this supplement. The quality and effectiveness have been excellent. The L- theanine has helped with my quality of sleep. I have had an overall improvement in my pain relief and my digestion. I like that this product is easy to swallow and doesn’t upset my stomach. I have also seen an improvement in my cognition. It is a good value for the money compared to other supplements. You get 150 pills which is a 5 month supply. I would recommend these supplements and would buy them again when I needed to buy this supplement again.

I've tried a few PeakPury nootropic stacks- most of them don't have any smell, but something in this one is aromatic. Nothing bad at all, if anything it's probably a testament to the variety of ingredients and freshness. There's a lot number and 04/2025 expiration printed clearly on the bottle.Good blend of ingredients here, and it's interesting that PeakPury makes such a variety of these nootropic style blends, sometimes with only a couple ingredients shifted around (lion's mane and l-theanine in this one interested me especially), though it would be very nice if they'd just list the quantities of ingredients in the "proprietary blend" for dosing transparency. My only other complaint is that the bottle advertises that it is lab tested, though I can't find anything about which lab or the results despite my best googling efforts. It'd be nice if they'd disclose that information.Anyway, that's not really out-of-the-ordinary, unfortunately, and it still seems like a quality product by all other metrics.

Maybe it's all in my head, but after taking a pill a day for the past week, I do feel better with a bit less forgetfulness than I had before. I know, it could just be wishful thinking, but I'm going to keep taking these as whatever helps me focus and decreases my absentmindedness is worth continuing...well, forever.I usually take no supplements whatsoever, but I heard good things about Lion's Mane and figured it was worth a shot to see if it had any impact on me. Of course, this has a lot more than just that and all combined is supposed to give people a stronger mental focus, which I sure could use at work and in life in general. And with 150 capsules at 1/day, it'll last 5 solid months. So great price for how much you get of this product.

I have used Lion's Mane supplements for about 6 months now, and I have noticed a definite improvement in my short term memory. My long term memory was always good, but as I got older I found I would forget something that I was just thinking about a few minutes earlier. Lion's Mane supplements have really helped improve that. The additional components of this supplement seem to help even more. I highly recommend this for mental clarity.

good price for "all in 1" supplement, that says it supports cognitive and mental focus, supports calm and mental energy. The title description says it is "made in USA" and I could not find that on the bottle and the company's website does not show list L-Theanine, Alpha-GPC, Lion’s Mane & Phosphatidylserine product, so if that matters to you, skip this product.

easy to swallow, tastless, helps the energy and doesnt hurt your stomach.helps with sleep too.

I started taking this hoping it would give me a little mental edge without the crash of caffeine-heavy alternatives. For the first couple of weeks, I actually noticed a decent bump in focus—less brain fog, easier time zoning in on work, and fewer “what was I doing again?” moments during long stretches at my desk. The blend felt smooth, without the jittery edge I usually get from energy supplements, which I appreciated.But somewhere around the third week, the effect started tapering off. Not entirely gone, but just… muted. I didn’t feel that same mental clarity or drive—it was like my brain adjusted and shrugged it off. I also wouldn’t describe the energy as “long-lasting”—I was definitely sharper in the mornings, but by mid-afternoon, it wore off. No crash, which is good, but also no staying power.I do like that the formula includes solid nootropic ingredients like Lion’s Mane and Alpha-GPC, and the capsules themselves are easy to take with no weird aftertaste. The 150-count bottle is generous, so you're set for a while without having to reorder.Bottom line: it's worth a try if you’re curious about nootropics and want a mild, caffeine-free focus boost—but just know the initial impact might not hold steady over time.
