most people dont get vitamin d from the sun because i read in an article that you would need to not shower for 24 hours after sun exposure in order for the majority of the sun to turn into vitamin d.
also, i can see how vitamin d can help. i started drinking 2 vitamin d emergen-c’s everyday and i noticed feeling more normal after 3 or 4 days of no masturbation and drinking those. they definitely play a part… but they are by no means a cure.
