I've worked up to 5,000 mg of MSM (increased 1,000 mg each week) to treat melasma on my face. During the second week at 5,000 mg, I began experiencing some chest tightness and shortness of breath. Is this common? The only other medication I'm taking is Zyrtec daily for allergies.
Also, if I decrease my daily amount of MSM, will it still work on fading/eliminating the melasma? Will it just take longer at a lower dose?
