D-Serine - Amino Acid for Cognitive and Neuroprotection Support & Mood Enhancement - No Animal Content 90 Count 700mg Vege Capsules

Relentless Improvement is an approved brand of nootropics from the Reddit nootropics approved vendor list. Their main problem is they often discontinue products, so I'm not sure how long this is going to be around.The form of serine usually found from other vendors is L-serine, which is **not** the natural form of serine present in the body and brain.D-Serine is the correct isomer of serine present in the body and brain, and it's unusual to be able to find it available from anyone. Relentless Improvement so far seems to be the only source, so get it while you can!

D-Serrine is a fascinating Nootropic, if you are concerned about NMDA receptor hypofunction and want to take steps towards remediating it. I hope the company keeps this in stock and ensures quality. I will keep buying in size!

A a single capsule makes me sleep deeply with absolutely no grogginess the next morning. I have meaningful and enjoyable dreams. This is very simply the most effective sleep aid I have ever tried. Back ordered because of what I suppose must be high demand.

Took my first dose today and I feel uplifted.😀

Addressing the review left by user Grenlock:Your comments are not accurate. Serine is found as both l-serine and d-serine in the brain, and the equilibrium is maintained by an enzyme present in the brain known as serine racemase (SR) which racemizes (converts) l-serine into d-serine. Source: I am a PhD candidate nearing the end of my dissertation research on NMDA receptors. The wikipedia page for serine racemase appears to be quite accurate, if you're interested in knowing more.D-serine has shown efficacy in studies where it was used to augment exposure therapy for treating a variety of conditions such as social anxiety, PTSD, and fear of public speaking. The idea is that it facilitates the consolidation of the newly formed memory of how the anticipated negative consequences of the exposure to what you fear didn't actually happen. Some studies ssuggested that d-serine is more effective at this when the practice exposure to what you fear ends on a positive note as opposed to a negative one. Again, all d-serine is doing is making it easier to consolidate the memory of the experience into a long-term memory.The 700mg/capsule dosage allows for the same dose escalation which was used in various studies.

Not for me.

I plan to send off a couple of capsules to a lab to see what they contain. D-Serine is hard to find except as a powder which is hard to work with, so I'm glad I found this.

dont trust it
