Provides amino acid precursors for healthy neurotransmitter activity, supporting mental function and healthy mood*.

Age-related decreases in levels of several amino acids may influence cognitive function. Amino acids are important intermediates in the production of neurotransmitters in the brain and are involved in neuromodulating activities. l-Tyrosine is an amino acid naturally synthesized in the body. It is the precursor of the neurotransmitters l-dopa, dopamine, norepinephrine, epinephrine, supporting mood and mental clarity. DL-Phenylalanine provides a mixture of two essential amino acids, d-phenylalanine, and l-phenylalanine. In the body, l-phenylalanine converts to tyrosine, enhancing neurotransmitter support. A separate pathway allows both d- and l-phenylalanine to support levels of the compound phenylethylamine, a function not provided by l-tyrosine.

The serotonin precursor l-tryptophan is included to support emotional well-being, relaxation, and restful sleep. In a double-blind, placebo-controlled study, l-tryptophan supported healthy emotional processing and promoted a positive outlook in women. Taurine is considered an inhibitory amino acid, helping to maintain healthy glutamate and other excitatory amino acid activity in the brain. This provides neurosupportive action important for maintaining healthy brain cell function. Acetyl-l-carnitine plays an important role in multiple metabolic pathways in the brain. It also contributes to the production of the neurotransmitter acetylcholine and may support dopamine receptor function. As a result, acetyl-l-carnitine plays a role in memory, attention, mental clarity, and mood support.*

These Help!

Could be my imagination but I believe this, taken along with HTP-5, has made a difference in my cognitive clarity!

DC Person
No diff

I have been taking this for a solid month. Don't notice any change.

William Freedman
I have used other of your supplements and have been satisfied with them

Too early to tell. It was not an instant help but a little for the few days I started.

Helps my memory

I feel sharper and can remember things more quickly. Rids the brain fog. I love it and would recommend it to anyone having memory/functioning issues.
