@RuskinPrimal How many times should you drink the formula per week/day?

I'm 15 years old, 171 cm tall. My father is 193 cm and my mother is 166 cm. I have very little facial hair so far and I think I'm still in the middle of puberty.

My goal is to maximize my growth potential and reach my full adult height. What are the most evidence-based things I can do during puberty to support height growth?

Are there any nutrients that are especially important (protein, calcium, vitamin D, vitamin K2, magnesium, zinc, etc.)?

Are there habits that can reduce growth potential that I should avoid?

All according to primal diet of course

Its called Pityriasis Versicolor, why is that happening and how to get rid of it ?
