How does high-dose vitamin C intake impact vitamin B12 metabolism?
Answer
It may reduce the amount of vitamin B12 the body absorbs
High doses of vitamin C can interfere with the way the body processes vitamin B12. This interaction results in reduced absorption and metabolism of B12. To ensure optimal uptake of both nutrients and prevent the antioxidant properties of vitamin C from hindering B12 utility, it is recommended that individuals separate the intake of these two water-soluble vitamins by a window of at least two hours.
