So do people on metformin, people with absorption issues, and plenty of people who just chalk the tiredness up to a busy month
What is largely agreed on, however, is that B12 deficiency can reduce energy levels and therefore make it harder to stay active and maintain a healthy weight
This might result in increased body mass
For individuals with mild deficiency or low dietary intake, oral supplementation is often sufficient, with doses ranging from 1000-2000 mcg/day being effective (7)
