This widely-used vitamin may cause acne

Too much of a good thing may be causing acne breakouts. Researchers at UCLA say having too much B-12 vitamin in your diet may be the source of acne for some.

The nutrient, which is found in meat, dairy and eggs, provides plenty of benefits — it can promote a healthy digestive system, increase energy and mood as well as prevent memory loss.But a new study suggests that having too much B-12 disrupts a type of skin bacteria related to acne.

Scientists tested skin samples from 10 people with clear skin who were told to take B-12 supplements. Within a week, one person developed acne.

The vitamin caused the bacteria commonly linked to acne start pumping out inflammatory molecules known to promote pimples.

Previous research dating back to the 1950s has suggested that vitamin B-12 supplements could contribute to some people's acne.

The researchers at UCLA say it's not clear what this means for people with acne or those who want to avoid it — so it's too soon to suggest avoiding supplements or foods that contain the vitamin.
