Roll Call does not check drug interactions or assess personal safety.
Ethyl alcohol, used in liquid supplement formulations as a solvent to dissolve plant extracts and as a preservative to extend shelf life.
Why it’s used
Included for manufacturing reasons: it helps extract and stabilize active compounds in liquid tinctures and extracts rather than being taken for an effect of its own.
What the evidence says
There is no efficacy question here, since it functions as a formulation solvent and preservative rather than an active ingredient. The amount present in a typical dose of a tincture or liquid extract is generally small.
