>>14249113>6k>"high dose"Retard alert. If you are deficient (which is like a 95% chance if you don't live near the equator and spend a lot time outside) 6k is nothing. People get prescribed (weekly) 100k pills when they are deficient. I've teen taking 10k for years without any trouble. For covid research, the patients were given daily 50k pills
OP google it if you must, but if you are deficient, 6k won't do shit. Do make sure to take magnesium and K2, and take it with your meals
