How Expired is Expired Vitamins and Supplements?

Most vitamins are considered safe for up to two years past their expiration date (unless they contain mold), but may become less potent over time. Unopened vitamin supplements are more likely to retain their potency because moisture, light, and oxygen are less likely to affect them. Pregnant women and people in need of regular supplementation due to deficiency should talk to their doctor before relying on expired vitamins. Technically, yes, vitamins do expire.

First of all, it’s important to note that the Food and Drug Administration (FDA) do not require supplement manufacturers to provide expiry dates on vitamin or mineral supplements. However, manufacturers generally list a shelf life of two years, provided vitamins are kept in their original packaging and stored in optimal conditions.

Expiration dates on vitamins reflect the day up to when a manufacturer can guarantee the supplement’s full strength (potency) and safety. Adhering to vitamin expiration dates ensures you get the nutrient dosage listed on the supplement and the nutrition you need.

The shelf life of a supplement depends on its form, its contents, and how someone is storing it. Factors that can contribute to vitamins losing potency include:

> extreme temperatures

> exposure to light

> exposure to oxygen

> pH levels

Chewable or gummy vitamins are more susceptible to moisture than capsules or tablets. Vitamins in tablet or capsule form may remain potent for several years.

Is it safe to take expired vitamins?

In general, it is relatively safe to take an expired vitamin supplement. It is unlikely to cause harm, as most expired medications and supplements do not usually become toxic, but only likely to lose potency.

Regarding supplements, a person should not take those that:

> show signs of mold

> have a strange odor

Immediately dispose of vitamins that look moldy or damp or have an unusual smell.
