Reading an article on 🍆💦 as Super Food which seemed to suggest Semen is a great source of "vitamin C, B12, ascorbic acid, calcium, citric acid, fructose, lactic acid, magnesium, zinc, potassium, sodium, fat, and hundreds of different proteins."
I had to read more about it and well, it does but not necessarily in enough quantities to make a huge difference. So do not forget your Vitamins just yet.
