I was pretty deficient in Vitamin D, not uncommon in Northern Michigan. Optimizing it did not benefit me mentally, however it did greatly improve some chronic muscle/joint pains I was experiencing. I've not heard that it will benefit libido, but exercise boosts endorphins and testosterone which can boost libido.
