Do You Keep Supplements In The Fridge? Here’s What The Experts Say

Many people wonder about the proper storage of dietary supplements — specifically, whether these products should be kept in the refrigerator. The answer isn’t a straightforward “yes” or “no” because proper supplement storage depends on the type of supplement, its formulation, and packaging guidelines. This article explores expert opinions on supplement refrigeration and demonstrates how trusted laboratories like Qalitex support dietary supplement manufacturers through advanced testing services to ensure shelf life, stability, and regulatory compliance.

Why Consider Refrigeration for Supplements?

Some supplements, such as probiotics or fish oils, are sensitive to heat, moisture, and oxygen exposure. Refrigerating these products can prolong their potency and prevent spoilage. However, many other supplements are formulated to be stable at room temperature and may degrade if refrigerated due to moisture buildup or condensation. As reported on MindBodyGreen, it ultimately depends on the specific supplement and manufacturer instructions.

Common Supplements That Often Require Refrigeration:

• Probiotic capsules and powders
• Fish oil and omega-3 supplements
• Liquid vitamins and tinctures

Supplements Usually Stored at Room Temperature:

• Multivitamins
• Most mineral supplements
• Herbal capsules and extracts in dry form

Expert Storage Recommendations

Experts advise checking the supplement’s label and manufacturer guidance to understand storage recommendations. If refrigeration is indicated, maintain a constant temperature and prevent exposure to light and moisture. Conversely, for products intended for room temperature, storing them in a cool, dry place away from direct sunlight is critical for maintaining their efficacy.
