A notable discovery from harward Medical School shows that vitamin B12 is involved in DNA production and supports nerve function, indirectly affecting sexual ability through mood, energy and nerve health.
B12 improves erectile function by producing nitric oxide (NO) - a neurotransmitter that dilates blood vessels, increasing blood flow to the penis. Men with B12 deficiency are at high risk of erectile dysfunction (ED), and adequate supplementation of B12 helps improve blood circulation significantly.
In addition, vitamin B12 also affects sperm quality. Research from the University of Tokyo (Japan, 2007) shows that after 3 months of B12 supplementation, sperm density increased by nearly 60%, along with improvement in mobility and shape. This makes B12 an important micronutrient in male reproductive support regimens.
Vitamin B12 deficiency not only causes chronic fatigue but also affects mood, leading to stress and reducing sexual desire. People who diet low in B12 (especially vegetarians, the elderly or people with stomach and intestinal diseases affecting absorption) are susceptible to energy loss, negatively affecting their physiological life.
Vitamin B12 supplementation sources can come from foods such as beef liver, salmon, eggs, milk or tablets, injections (as prescribed by the doctor).
However, according to Dr. Ranjith Ramasamy - a male expert at the University of Miami (USA), vitamin B12 supplementation requires a prescription and blood test, because excess B12 does not bring benefits and can cause mild side effects.
