Expired Vitamins: When to Discard and When to Keep
Translated & summarized from Maariv by baba
Expired vitamins and supplements may lose potency over time, with effectiveness depending on the product type and storage conditions, according to Dr. Maya Rozman. While minerals are stable, vitamins and especially Omega-3s degrade, particularly once opened. Dr. Rozman suggests discarding most supplements three years past their expiration date, and being especially cautious with Omega-3s.

Expired vitamins and supplements may still be usable, but their effectiveness depends on the type of supplement, how it was stored, and whether the packaging has been opened, according to Dr. Maya Rozman. The expiration date does not signify a sudden spoilage, but rather a gradual degradation of active ingredients, leading to a lower dosage than indicated on the label.
Dr. Rozman explains that the longer the time elapsed since the expiration date, the less active ingredient remains. She suggests discarding most supplements if they are three years past their expiration. The condition of the packaging is also crucial; an unopened container protects the supplement from moisture, oxygen, and light, which accelerate degradation. Once opened, exposure to air, moisture, light, and heat can significantly reduce the vitamin's potency.
Minerals like calcium, iron, and magnesium are chemical elements and are more stable than vitamins, meaning they do not degrade in the same way after their expiration date. However, Omega-3 fatty acids, found in fish oil supplements, are highly susceptible to oxidation. Oxidized Omega-3s can be found even before the expiration date, especially in liquid or opened containers. Dr. Rozman advises a stricter approach to Omega-3 expiration, recommending discarding them if past the date, particularly if the bottle has been opened.
