I am trying to look after my body esp since my eating disorder I want to gain weight and make long term changes, someone recommended kelp pills to increase my metabolism as I have found that I am putting weight on whenever I eat and I have to tell you I do not eat 3500kcal to gain a pound but what seems like a healthy day consisting on fruit and chicken salad makes me put on lbs. where can I get a kelp pills in uk, and what other vitamins can I take to make my periods come. did anyone else lose their periods and then they came back?
