Hi, I have thinning outer eyebrows, nails slightly splitting and seldom itchiness on legs and under right rib cage. Also had a slight bump in the right centre of my neck for the last 1-1/2 years and get tired/lethargic when I eat spicy foods. I m on an all organic vegetarian lifestyle...no sugar, white flour, dairy or wheat, have been for years as I ve had allergies since I was a baby. I m thinking Thyroid catalyst from B12 and Iodine deficiencies ??? as I have not, until now, gotten much of either in my diet AND I have had gallstones in the past. Otherwise I feel good :) Thank you.
