Tag: B12 overdose symptoms

While a true vitamin B12 overdose is extremely rare due to its water-soluble nature, high intake from supplements or injections can cause unpleasant side effects such as headaches, fatigue, and even acne. It is crucial to understand these symptoms to manage your intake responsibly.

According to the National Institutes of Health, most adults need about 2.4 micrograms of vitamin B12 per day. But what happens if I take vitamin B12 daily in higher doses, as found in many supplements? While excess is generally considered safe for healthy individuals, understanding the full picture is crucial.
