Polysorbate 80Emulsifier
Chassaing et al. 2015 (Nature, PMID 25731162) tested polysorbate 80 directly and showed it thinned the gut mucus barrier, altered microbiota composition, and induced low-grade inflammation and metabolic syndrome in mice. The strongest human evidence is for a related emulsifier rather than polysorbate 80 itself: Chassaing 2022 (Gastroenterology, PMID 34774538) was a controlled human feeding RCT of carboxymethylcellulose (CMC) that found microbial encroachment into the mucus layer — polysorbate 80 has not been tested in an equivalent human trial. In vitro work (e.g. Roberts 2010) shows polysorbate 80 enhances bacterial translocation across intestinal epithelium, and observational data link overall dietary-emulsifier exposure to IBD risk. EFSA is mid re-evaluation of polysorbates (E432–E436). For a supplement excipient with purely cosmetic function (improving the look/texture of soft gels and liquids), the gut-barrier risk profile is unfavorable when safer alternatives (sunflower lecithin, MCT carriers, gum acacia) are widely available.

Purified WaterSolvent
Water meeting USP specifications used as solvent/vehicle in gummies and liquids
Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
How to Take It
Best taken in the evening
The Magnesium in it is what pulls this toward the evening. Take it with a meal containing fat — the vitamin D in it absorbs poorly without one.
With a meal containing fat
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron
