That is the same brand that i take, it is good to know, that you don't have to go to a deal of expense, to derive such great benefits.
I really happy for her.
You may have read that i have had urinary frequency my entire life and i am 49, up to 40x a day. It does seem to have slowed somewhat.
I will continue to take the MSM and hope for as good benefits as your sister.
I just think that is so great. She must be so much happier now.
