Ergothioneine with Clinically Studied MitoPrime® - High Potency 30mg with 98% Purity - Fermentation-Based L Ergothioneine Supplement - Longevity and Immune Support - Third-Party Tested, 90 Capsules

Seller is good. Offered full refund when the product did not suit me. So you should definitely try it as it is risk free.

Arrived. Seems to do the job.

I suffer from brain fog and have been taking this for several months now and find that I see noticeable difference in my focus. I haven’t experienced any side effects and when I take it with my morning coffee feel very significant mental boost. For $19.95 You get a three month supply and it claims to have a 98% verified purity. I am no scientist, but I do know my body and anything that can give me an edge at work. I’m gonna try.

I am mid 50, feel tired in the afternoon very often. This supplement seems boomed up my energy level during daytime.

works well on neurological energy production.

I ordered this Ergothioneine MitoPrime® to see if I could reduce my caffeine intake without compromising my energy levels. And so far this appears to be a successful experiment. Simple but good ingredients, easy to take, and no negative effects. And less caffeine daily. Win win.

As a 30-something-yr-old new to L Ergo Theoneine, I’m already seeing noticeable changes in my focus. It’s realy helped me push through those mental marathons without feeling too drained. The taste is slightly weird, but it’s still tolerable . I haven’t experienced any severe side effects yet, although I do get a mild headache if I take too much. Overall, I’d definitely reccomend it to anyone looking for a mental boost without going overboard on caffeine which is the baseline here.

I find supplements incredibly difficult to review, as you generally need to go through a couple bottles or three to see results. BUT I've taken this supplement for a solid month now, and I haven't gotten sick or anything, so there's that. ;) I've got a supremely powerful attention deficit (diagnosed and only getting worse with age!), so I'm no stranger to this stuff...or anything designed to boost memory or cognitive function, really. So I'll keep going with this particular product and see if I notice any improvements, and then I'll try to remember to come back and edit/update my review!...which is funny b/c I know there's absolutely no way, nada, zero percent chance that I'll remember. ;)
