Tag: B12 safety

The Recommended Dietary Allowance (RDA) for vitamin B12 for most adults is only 2.4 mcg, yet many supplements contain 1000 mcg or more. The question of whether **is 1000 mcg of B12 per day too much** requires understanding the complex absorption process rather than just comparing the numbers.

In the U.S. and U.K., vitamin B12 deficiency affects nearly 20% of adults over 60. While supplementation is common, it's crucial to ask: are there any negative effects of taking B12, especially in high doses?

Despite online claims suggesting otherwise, cyanocobalamin, a common synthetic form of vitamin B12, is widely considered safe for human consumption and is not toxic. The misconception stems from the presence of a minuscule, harmless cyanide molecule within its structure. This article explores the science behind its safety, dispelling the myth of its toxicity and clarifying how the body processes it effectively.
