Lactose Intolerance Pills Work Best in the Range You Can Probably Already Handle
Most lactose-intolerant adults can tolerate about 12 grams of lactose, roughly one cup of milk, without any pill at all, especially when consumed with food. Lactase enzyme supplements perform best at exactly these moderate doses (12 to 25 grams, or about one to two cups of milk) and become less reliable as lactose intake climbs higher. That creates a practical paradox: the pills are most effective in the range where many people already manage fine, and least reliable when you're pushing past your natural threshold. That doesn't make them useless. It means they're a tool for expanding your comfort zone with dairy, not a free pass to eat unlimited ice cream.
