Food supplements whilst on HT

I have just started my HT (Bicalutamide) on a six-month course; RT in three months time.

I usually take daily doses of Vit D, zinc and cod liver oil. Though I haven't been prescribed it, I know that calcium is often taken, and perhaps Vit C. I have also heard that increase in protein (macronutrients) is sometimes advised, though to cut back on carbs. I eat generous amounts of fruit and (steamed) veg (love them!), though not a big salad fan. What about sage tea (never heard of it until I saw it on one of the forums) and turmeric?

Obviously, I want to stay as healthy and strong as possible (I've made a vow to walk daily, come hail or shine) as the treatment kicks in, and I know I might get excess belly fat, so any other advice on supplements would be so appreciated. 

Thanks so much,

David
