Tag: 10000 mcg b12

Despite the recommended dietary allowance (RDA) for adults being just 2.4 mcg per day, some B12 supplements contain potent doses of 10,000 mcg or more. This vast discrepancy leads many to question the safety and necessity of such high intake.

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.
