After the first 3 weeks of taking Kelwell I had an improved skin condition, better sleeping, weight reduction (I lost 2 kgs) and higher energy levels which for a 90-year-old are big benefits. The magic is in the iodine (possibly minimal in my diet) stimulating my thyroid gland and hence my better metabolic rate. I have been taking Kelwell since the beginning of September 2013 and am very happy with the benefits I am experiencing!
