Okay ladies. I am currently TTC baby #3 and I'm taking prenatals of course, Priobotic(to keep my PH level elevated, I have a very acidic environment, prone to infections) B Complex(B6, B12, Biotin, Folic Acid) what is something that helps fertility? That I can find at my local Walmart(on my way now lol) also my husband takes NO vitamins. I finally convinced his punk butt to take some. Haha! So what's the best vitamin/supplement for men? & remember it has to be at Walmart(no online things)

Please help!! Thanks!!
