What is Doctor's Best Natural Brain Enhancers with AlphaSize & SerinAid?

AlphaSize® (GPC, GlyceroPhosphoCholine) and SerinAid® (PS, PhosphatidylSerine) are phospholipid nutrients intensively researched for their benefits to diverse human brain functions.* These nutrients naturally complement each other: Alpha-GPC rapidly delivers choline to the brain across the blood-brain barrier and is a biosynthetic precursor of the acetylcholine neurotransmitter*; PS is an important phospholipid membrane component of cell membranes and plays a key role in cell cycle signaling* These nutrients support attention, learning, memory and other cognitive functions and can support brain health and mental performance*.

How does it work?

GPC: The body uses GPC (Glycerophosphocholine) to make at least three functionally diverse nutrients-choline, acetylcholine, and phosphatidylcholine (PC). These three GPC metabolites are needed for supporting healthy gene regulation, mental and visual performance, the brain's stimulation of voluntary muscles, and the non-conscious coordination of internal organ functions by the autonomic nervous system. GPC and its metabolites are fundamentally involved in growth, renewal and overall health maintenance, across the human lifespan.

PS: Best Natural Brain Enhancers provides the vital brain nutrient phosphatidylserine (PS) in a matrix of other phospholipids. PS is a building block for the brain's nerve cell connections (synapses).* More than 30 double-blind clinical trials document the benefits of PS for memory, learning, and other cognitive functions. PS also helped in coping with mental and physical stress.*

Caution: This supplement caused intense migraines.

I don't have a history of migraines, yet this supplement causes intense migraines. I took only 1 tablet daily for about 4 days. When I stopped taking it, no more migraines. It may not be for everyone.

My mom, God rest her soul

My mom wrote about phospholipids and I experienced the brain boost from the serine. GPC is the bioavailable form of choline which is Vitamin B-4, also known as Adenine). But I see that pre-work out powder has both GPC and CDP, another choline form. Then Solgar sells choline with inositol whatever that is and why it is with the choline I dont know.

Like Finding The Missing Puzzle Piece

I was diagnosed with chronic depression about a decade ago. The last 3 years symptoms have gotten much worse, bad enough that I need help daily to be moderately functional. I've spent 2 years trying a motley of supplements and nootropics, and alot of what I take regularly helps a lot. But this.... The first day I took this when it kicked in (less than 30 mins), I think I cried from joy or came close to it. My depression fog disappeared and I could..."see" how much clearer my mind was before the depression got so bad. I feel like I understand myself again, like everything is mentally in its proper place. I haven't felt in control of my mind like this in about 15 years. I've been taking these for a month and only take one a day, with all my other vitamins and supplements in the morning right before or after a cup of coffee. I haven't noticed any sort of side effect or adverse result whatsoever. I remember where my keys are, and what I have to do around the house, and I don't have to repeat things in convo 3 times to remember anymore. All my stress from being scatterbrained is gone so I can focus on just getting things done. ....I don't think this did all the heavy lifting, but it has definitely done what the other stuff has not. This was the final piece in my regimen to get me back to myself without going on antidepressants. I'm sure there are other brands that sell this nootropic blend. I've been using Doctor's Best for some of my other supplements for 3 or 4 years now. All through COVID, I've never had supply or delivery issues, the product is consistently effective and the price stays consistent and reasonable. I recommend this product specifically because the vendor company has proven itself to be reliable for me.

I could not tell if this worked

I took a chance by ordering these vitamins. It is a little unnerving to order something for the brain. But I'm okay, I just could not tell if these made a difference or not.

Turn your brain on

I've used several nootropics support my brain. I notice the difference when it's missing from my stack. Everyone should add this to enhance recall and problem solving capabilities.
