Mucuna pruriens and Food Cravings

Weight issues are higher than normal across a range of mental health concerns.1 The dopaminergic system of the brain as it relates to unhealthy body weight is a common link among these conditions.

For example, Blum and colleagues observed dopaminergic reward circuits are disrupted in weight issues (as well as in drug dependence), contributing to unhealthy eating behaviors.2 Decreased D2 receptor availability has been found in subjects with these eating patterns, as well as in those with weight management problems.3 Both alcohol and carbohydrate bingeing are known to stimulate dopamine.4 Food cravings are part of unhealthy eating patterns. Joyner et al. have observed that food cravings are a significant mediator between such eating patterns and elevated BMI.5

Although many situations contribute to food cravings, genetics can play an important role.  Downs and colleagues have observed that individuals possessing a lack of serotonin and/or dopamine receptors and an increased rate of synaptic dopamine catabolism (due to a high catabolic genotype of the COMT gene) are predisposed to self-medicating. This COMT SNP, as well as others, can predispose individuals to weight issues via cravings, in an attempt to raise both dopamine and serotonin.6

The nutraceutical most studied to increase dopamine is velvet bean, Mucuna pruriens. Mucuna has a long history of use to increase dopamine.* Its seeds, in particular, contain up to 5.8% L-DOPA, immediate precursor to dopamine on the catecholamine pathway.*7 Mucuna ingestion is known to reduce food intake, body weight, and BMI.*8 It is also used to address male reproductive issues in both human and rodent models.9-11 In addition, aqueous extracts have been shown to demonstrate hypolipidemic effects.12 Mucuna in Procite-D™ provides L-DOPA as substrate for dopamine production.*

DL-phenylalanine Support for Aches & Discomfort, Appetite, and Mood*

DL-phenylalanine (DLPA) is a combination of the L form and the D form of the essential amino acid phenylalanine. L-phenylalanine is the amino acid initiating the catecholamine biosynthetic pathway, which includes dopamine.*

D-phenylalanine, an isomer of the L form, has been studied since the 1980s as an enkephalinase inhibitor.*13 Enkephalinase inhibition leaves the brain more of its endogenous opioid peptides such as enkephalin, endorphin and dynorphin. These are known to address aches and discomfort, as they are mu-opioid receptor agonists.*14 D-phenylalanine is also converted to β-phenylethylamine (β-PEA) via AADC (amino acid decarboxylase).15 β-PEA has excitatory action and may reduce appetite.16 DLPA has also been useful for various forms of low mood.*17

N-Acetyl-Cysteine and Oxidative Stress

Cysteine is the rate-limiting precursor to glutathione, master intracellular and hepatic antioxidant. NAC has shown efficacy in boosting glutathione, in reducing ROS (reactive oxygen species), and protecting neurons.*18 NAC was shown to attenuate the oxidative stress and alterations in glutathione metabolism associated with β-cells cytotoxicity, addressing some metabolic concerns.*19

Procite-D™ from Sanesco includes Mucuna, DL-phenylalanine, and NAC, along with neurotransmitter cofactors such as B vitamins, selenium and the catecholamine building block N-acetyl-tyrosine.* Procite-D is one of several Targeted Nutritional Therapy™ formulas included in the Communication System Management™ (CSM) clinical model.

A recent American Society for Nutrition poster presentation provides evidence that the CSM clinical model, in combination with clinician care, positively affects BMI, weight-related quality-of-life markers (comorbidities), and neuroendocrine markers related to weight. Among the weight-related comorbidities with statistically significant improvements are mood and reductions in  food cravings such as salt and sugar as well as aches and discomfort. All these factors may be addressed by ingredients found in Procite-D.*
