An emulsifier that helps oil-based ingredients mix evenly in your supplement.
FDA GRAS and used in food for decades. Some animal studies at very high doses raised gut microbiome concerns, but supplement amounts are far below those levels.
Yes. It's used as a stabilizer in several vaccines at very low doses. The safety record is extensive.
At food/supplement doses, no meaningful effect. The animal studies showing microbiome changes used much higher concentrations.

Some ingredients build up over weeks. Others act fast.
The compound effect of consistent dosing.
Check the cautions section if you have a pre-existing condition.
Some ingredients you feel. Others just work in the background.
Consumer perception. Some people prefer products without synthetic emulsifiers, even safe ones.
Polysorbate 80 is derived from oleic acid (olive oil fatty acid). Polysorbate 20 is from lauric acid (coconut). Both are emulsifiers with slightly different properties.
True allergy is extremely rare. Some people with sensitivity to sorbitan-based compounds should be cautious.
Nonionic surfactant that reduces surface tension between oil and water phases, creating stable emulsions. Can also improve solubility of poorly water-soluble compounds.
Polysorbate 80 has emerging evidence.
Derived from sorbitol and oleic acid (often from olive oil)
Sorbitol is reacted with ethylene oxide, then esterified with oleic acid.
