Phosphatidylserine - 400mg Formula - World’s First 50% Purity - Highest Purity in the US - Soy Free Phosphatidylserine Supplement - 90 Veggie Capsules

Have been using this product for a few months. I think it does add to overall health and good for the brain. I do take short break from taking it so it doesn’t become ineffective

This is the best form of serine to assimilate in the body. Works for mental clarity and a better mood. Give it a week or so to really notice better clarity. It will build with time. Make this as one of your improved mental focus products. It should be easily digested for everyone! Enjoy!

I’ve used a number of brands of this product and this one clearly works the best. Individual biology can vary so you simply have to try various ones until you find a good fit. For me this is the first one that I feel an actual effect from. Very subtle of course, but clearly there. The price point is good too, and that doesn’t hurt.

Seems alright

Excelente. Me ayudado bastante, eh sentido la diferencia en pocos dias. Mi cerebro lo necesitaba mucho.

Toniiq makes great supplements and this is no exception. I have a noticeable reduction in stress induced brain fog and an improvement in memory when taking this product. I have tried to stop after the bottle runs out but always go back.

Pleased with the packaging and product

If it wasn't for the Magnesium Stearate filler, it'd be a 5. Really a bummer that this bad filler is in here. Took it at 6pm and it helped relax before bed. Don't expect miracles. It's more to calm you down a bit.

I bought it for my mum. She has some supplements everyday. Hopefully working well.

If you're suffering from chronically high cortisol levels this product is a must have.
