I struggled with body odor (it smelled like old lunch meat... To be so discriptive! ). I started taking flax seed for other reasons (fiber intake and hormones). The body odor receded, but I do not know why... Either because I was having more active bowel movements or it changed my hormones. I am just happy I don't stink anymore!
Now, my husband struggles from a sore back, and no, it is not related to a vitamin/ mineral or exercise issue... He stinks! Because he bathes only once a week. If he would only shower more I would not make him sleep on the sofa! Hence the back problem would be solved! LOL
