“Vitamin B12 supplementation enhances DNA synthesis. However, the lack of this trace element is also bad – a person may develop optic neuropathy. In this case, the optic nerve suffers, which also leads to certain vision problems. So, a person can begin to see the world in black and white colors, ”explained doctor Monika Wassermann.
Doctors also noticed that before vision began to fall, patients complained for a severe headache. A sharp deterioration, and then – recovery within a few hours or even days.
Important detail: this relationship remains to be proven. So far, doctors have put forward only a hypothesis. “Of 86,813 people who reported taking vitamin B12, only 27 men and women reported this unusual side effect. More research is needed,” concluded Dr. Tariq Mahmud.
