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!

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.

Seems alright

Pleased with the packaging and product

I have used this supplement before from another manufacturer/supplier. It worked so well that I could remember song names and dates from my youth in the 60s. I am not a memory giant and never have been, so it was quit a delightful experience showing off my memory to my grandson as we discussed music of the days back then. I returned to trying this supplement again to see if it would help my 90 year old mother's memory. It has collapsed lately due to age and I suspect the pain medication she has to use now. The good news is that she is now remembering that she has seen a television show before when that hardly ever happened. We could watch the same show story several times before she would realize that she had seen it before. I do not know if this is related but her mood has improved and she can now enjoy a bit more complicated mystery shows and still keep up with the story line without getting so frustrated. We are both only taking one capsule per day for the last 30+ days. She has a very sensitive digestive system and has shown no stomach problems. It is good to watch her improvement. I have also noticed that I am 'up' to doing more things myself that require memory and learning, like getting my private pilot license at 70 years old. Being able to remember names is a nice side benefit also.

I have used Phosphatidyl Serine along with other cognitive supplements for quite some time, many brands in the past but the Toniiq product outshines the rest. Real point of this review is two folds: How was the service and what did the product do for me? Amazon's service is of course second to none and Toniiq is a very quality conscious and customer centric company with excellent service. I have found this Phosphatidyl Serine to be of very good quality, highly effective as a brain's performance enhancing nutrient, you can feel the effects in a few days if you keep taking it regularly. Keeps my memory sharp and makes thinking and ‘imagineering’ easier to flow. I can also feel my over all Brain function like focusing, improving as well. I think it is penetrating the brain cells and keeping them healthy from the inside out. It has also improved my comprehension, retention and retrieval of information and when you combine it with Bacopa, it makes difficult concepts easier to grasp. I would highly recommend it to people who want to keep their memory and over all brain function sharper and youthful.

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.
