Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Amino acid and protein blends are sometimes used as adjuncts to support individuals with addictions to sugar or refined carbohydrates. The scientific rationale is based on the understanding that chronic consumption of sugar and refined carbs can dysregulate neurotransmitter systems—especially dopamine and serotonin—leading to cravings and mood disturbances. Several amino acids, such as L-tyrosine, L-tryptophan, and glutamine, serve as precursors for neurotransmitters and have been studied for their potential to normalize brain chemistry during withdrawal from addictive substances, including sugar.

Some small clinical studies and animal research suggest that supplementation with specific amino acids may help reduce cravings and withdrawal symptoms. For example, L-glutamine has been shown to reduce sugar cravings in anecdotal reports and limited trials, while L-tyrosine and 5-HTP (a serotonin precursor) may support mood stabilization and reduce the urge for sugar as a compensatory behavior. However, most studies are preliminary, lack large sample sizes, or are not specific to sugar/carbohydrate addictions but are extrapolated from research on substance use disorder. There is currently insufficient robust clinical evidence to recommend amino acid/protein blends as a primary treatment for sugar or refined carbohydrate addiction. More rigorous, large-scale human trials are needed to clarify efficacy and safety.
