Do any of you ever get brittle and breaking nails? I get them every once in awhile and I think it's when I may not be getting enough protein. I think I should increase my soy bev. intake for starters. I'm not underweight by any means but I may be needing something more in my diet. I've been taking a multivitamin daily for a week or so. I had forgotten to take it for quite awhile. Appreciate any ideas.
