How much should I take each day?

We dose YOU by body weight, not a one-size serving. Adults: your weight in kg × 0.15 ml. Children 11 and under: weight × 0.2 ml. So a 64 kg adult is about 9–10 ml a day. The 300 ml bottle shows two reference servings (7.5 ml and 12 ml), but the body-weight formula is what we actually use — I'll work out your exact amount.
