Tag: Safe b12 dose

According to the National Institutes of Health, vitamin B12 has no established tolerable upper intake level, suggesting a low potential for toxicity. This is a crucial point for anyone asking, "Is it okay to take 10,000 mcg B12 daily?" as the body's natural absorption limits prevent harmful overload in most individuals.

The recommended dietary allowance for adults is just 2.4 micrograms (mcg) of vitamin B12, yet many over-the-counter (OTC) supplements contain 500 to 1,000 mcg or more. Understanding how much B12 should I take OTC requires looking beyond the label to consider absorption, individual needs, and specific health factors.
