What Do You Need Vitamin B12 For?

We’ve discussed vitamins and minerals in previous posts but this week I’d like to continue elaborating on some common vitamins myths and beliefs. How much Vitamin B12 should you eat daily and what is it best for?

People often take B12 supplements as energy boosters and while some studies have shown it may have minor effects in temporarily improving mood, this really hasn’t been proven. B12 is necessary for adequate nervous system function, memory and mood.

B12 is found in animal derived products such as poultry, meat, eggs and dairy. How long do the reserves last? If you eat meat about 2-3 times weekly, your B12 reservoir will last for years without new intake and supplementation is not necessary. Only those who are fully vegan really need to worry about daily supplementation (the amount in a typical over the counter B12 pill), while for everyone else, there’s no need to go above and beyond a healthy diet and/or daily multivitamin.
