questionmarkblueI am often asked what products we use to help restore proper neurotransmitter function. The honest answer is that every single person requires a different blend of amino acids and cofactors to optimize their neurotransmitter levels, so identifying just one or two formulas is not feasible. However, there are several formulas made by CHK Nutrition that are used quite often (to learn more, see What products do you use to rebalance neurotransmitter levels?). These two products are called NeuroReplete and CysReplete.

NeuroReplete and CysReplete often form the basis for amino acid therapy, as together they provide a balanced foundation on which we can build up a person’s neurotransmitter stores in order to restore proper neurotransmitter function. NeuroReplete provides L-tyrosine and 5-HTP in a 10:1 ratio along with other vitamins and minerals necessary to convert those amino acids into the catecholamines (dopamine, norepinephrine and epinephrine) and serotonin, respectively. CysReplete provides L-cysteine and selenium to help restore proper glutathione products, aid in proper neurotransmitter function and prevent the possible buildup of methyl-mercury in the brain.

We receive inquiries every week as to why a person can’t find these products at their local health food or supplement store. The reason is that all CHK Nutrition products, including NeuroReplete and CysReplete are only available through licensed health care providers. One of the reasons for this is that although amino acid therapy is fairly simple in theory, it is quite complex in action (to learn more, see Neurotransmitter Imbalances – A simple overview (3-part series)). Extensive training and clinical experience is necessary to use these formulas properly. Failure to do so often results in further neurotransmitter imbalance and an exacerbation of symptoms.  As such, CHK Nutrition has made the commitment to only offer their patented products through licensed health care providers, which means that you can’t find them at your local health food store.
