1. It takes about 90 days to make sperm, so today already counts
Most men think fertility is a switch you flip the month you start trying. It is not. Sperm takes roughly 70 to 90 days to fully form, and every day of that window is shaped by what you put in your body. That means the version of you three months from now is being built right now. Foundations gives that window something to work with: eight clinically backed ingredients in one daily serving, made for men who would rather prepare than hope.*
