Vitamin B12 for female fertility

It seems that adequate amounts of vitamin B12 are necessary for female fertility. Women with low levels of vitamin B12 may deal with ovulation changes. Furthermore, low levels of vitamin B12 may interfere with the development of the ovum.[1]

Additionally, vitamin B12 deficiency may lead to defective implantation. On the contrary, women with high levels of vitamin B12 seem to have higher chances of having a baby, in both natural pregnancies and in pregnancies after ART (Assisted Reproductive Technology) treatment.[2]

As high vitamin B12 levels are vital for female fertility, scientists suggest that women should take a higher daily dosage than the recommended. Women who want to conceive could benefit from taking up to 7 mcg of vitamin B12 a day.[3]

Certainly, women should check their vitamin B12 levels before conceiving and also in early pregnancy.

Other necessary vitamins for increased female fertility are omega-3 fatty acids, Coenzyme Q10, melatonin, iron, vitamin C, and vitamin D. More here.

Furthermore, vitamin B12 seems to be important for male fertility, as well. High vitamin B12 levels play a key role on semen quality and sperm physiology. High levels of vitamin B12 may increase sperm count, enhance sperm motility, and even reduce sperm DNA damage![4]

Vitamin B12 may protect semen quality, as it helps reproductive organs function properly, decreases oxidative damage to sperm, and also decreases semen impairment, due to inflammation!

Additionally, men should have adequate amounts of zinc and selenium for increased fertility.

The recommended daily dose of vitamin B12 is 2.4 mcg a day. But, women who want to conceive may benefit from taking around 7 mcg of vitamin B12 a day.
