Hi, my name is Vikas and I'm 28 years old. I have thyroid and dyspepsia(indigestion). My T3 and T4 are normal. My TSH is 5.75 which is slightly above the normal range and my vitamin D is 11 which is less than the sufficiency level. I'm on medication taking medicines - supplements suggested by my physian for thyroid and vitamin D. I'm planning to increase weight. I weigh 46 kgs, my height is 5.3. I researched a lot on internet about Optimum Nutrition serious mass gainer supplement. Please help.
