Let's go!!! Your body is adapted to natural foods. Your body is smart and won't digest the food particles with toxins on them cause the body will recognize it as food (the raw milk in this case) only if it's raw. Drinking grain fed milk is very good, just not perfect. So you'll be fine. I would recommend to wait until its room temp, then lot it rest at room temp for a couple of hours and then drink it so the enzymes and everything becomes active. If your still growing then you should drink I'd say minimum 2L/day. Btw I just found a giga Chad farmer that sells me more raw milk despite the laws in sweden.
