Can I still take calcium tablets after they have expired?

Generally speaking, calcium tablets should not be consumed after their expiration date. The specific analysis is as follows:

The expiration date of calcium tablets indicates the period during which the ingredients remain effective and safe. After expiration, the content of effective calcium gradually decreases, making it unable to achieve the intended effect of calcium supplementation. Long-term consumption may lead to insufficient calcium intake, affecting bone health. Moreover, expired calcium tablets might undergo ingredient degradation, producing unknown impurities. Consumption of such tablets may irritate the gastrointestinal tract, causing discomfort such as nausea, bloating, abdominal pain, and even place a burden on other organs, contradicting the original purpose of calcium supplementation.

Before taking calcium tablets, carefully check the expiration date on the packaging and use only if within the valid period. After each use, promptly seal the bottle cap and store the tablets in a cool, dry, and light-protected place to avoid deterioration caused by moisture or high temperatures. If calcium tablets are found to be expired, they should be discarded immediately; do not risk taking them for the sake of saving. When needing calcium supplementation, purchase products within their expiration dates. If you have special health conditions, consult a doctor or pharmacist for advice and choose an appropriate method of calcium supplementation.
