CarboxymethylcelluloseThickener
Carboxymethylcellulose was the second emulsifier (with polysorbate 80) in Chassaing et al. 2015 (Nature, PMID 25731162), which showed mucus-barrier thinning, a microbiota shift toward pro-inflammatory species, low-grade inflammation, and metabolic syndrome in mice. Chassaing 2022 (Gastroenterology, PMID 34774538) tested CMC directly in a randomized controlled human feeding trial and found reduced microbial diversity and bacterial encroachment into the normally sterile mucus layer in a susceptible subset of participants. EFSA's 2018 re-evaluation could not establish a safe level due to data gaps. For a purely textural excipient, the gut-barrier risk profile is unfavorable when safer thickeners are widely available.
Medium Chain Triglyceride OilCarrier
Fractionated oils rich in C8/C10 triglycerides used as neutral carrier or anti-sticking agent
Natural FlavorsFlavor
Broad regulatory category of flavor constituents derived from natural sources. Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents. 'Natural' is a regulatory definition (21 CFR §101.22), not a safety guarantee.
Guar GumThickener
Natural thickener derived from guar beans
Monk Fruit ExtractSweetener
Zero-calorie natural sweetener derived from the monk fruit (Siraitia grosvenorii)
Sea SaltFlavor
Basic food-grade salt used for taste in supplements
Sunflower Seed OilCarrier
Common vegetable oil from sunflower seeds used as a carrier in softgels for fat-soluble nutrients
Xanthan GumThickener
Natural thickener from fermented carbohydrates
How to Take It
Best taken in the evening
Take at night. Other amino acids compete for brain uptake, so a protein-heavy meal blunts it. Take it between meals, away from food.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
On the label
Mix the contents of one packet (38 g) in 8-12 oz cold water and consume.
Do not combine with St. John's Wort
Each of these raises serotonin activity on top of St. John's Wort, and together they can trigger serotonin syndrome — agitation, rapid heartbeat, raised blood pressure. Not without medical supervision.
