What it does: It works by disrupting the metabolism and growth of molds, yeasts, and some bacteria, slowing or preventing microbial spoilage in products with higher moisture content.
How it is used: Commonly found in supplement options prone to moisture, such as gummies, syrups, and chewables, as well as in various processed foods and beverages to maintain freshness.
Natural sources and supplement forms: While sorbic acid occurs naturally in some berries, potassium sorbate used in supplements is synthesized and typically provided as a colorless, odorless powder or granule for easy blending.
Why it appears in supplement formulas: Potassium sorbate is selected to help preserve the quality, stability, and safety of moisture-sensitive supplements by guarding against microbial contamination and extending shelf life.
What to know before use: Most people tolerate potassium sorbate, but rare cases of mild skin or allergy-type reactions may occur, particularly with repeated or high exposure.
Interesting Fact
Preserving Freshness, Inspired by Nature
While potassium sorbate is produced synthetically for wide use today, its origin traces back to sorbic acid first found in rowan berries. This preservative is valued in supplements because it helps stop mold and yeast from growing, keeping products safe and effective for longer, especially in moisture-prone forms like gummies and syrups.
