Dear Doctor, I have hypothyroidism. My TSH level is higher than the normal range. T3 and T4 are fine. I go to the gym regularly and like to lift heavy weights. I am taking pre-workout supplement - Nitrous Oxide. I heard that this is not good for me but I want to take some pre-workout supplement. What should I do? Should I take some other type of supplement for strength, energy, focus, endurance?
Hi. That is a very good question. Revert back to a nutritionist online for further queries -->
