vitamin b12 injection overdose overdose: Side effects of taking too many supplements; know when to stop Vitamin B12 Overdose: How Much

Injections are used when patients cannot absorb Vitamin B12 properly through food or supplements

Patients with a history of allergy to vitamin B or cobalt should not receive this injection

As first described back in the 1950s, about one in ten people erupted in acne within days or even hours of getting an injection of vitamin B12, but it disappeared rapidly when the B12 shots stopped

Injections that rely on prescription medications are sometimes the exception to this rule, but patients who fail to modify their diet and exercise regimen tend to quickly regain weight when they stop receiving the injections
