Lactase tablets and post‑dairy blood glucose

Lactase tablets work only for lactose intolerance they break down the milk sugar (lactose) that can cause gastrointestinal symptoms such as gas, bloating, or diarrhea. They do not reduce the amount of carbohydrate (including lactose) that is absorbed as glucose, so they will not prevent a rise in blood‑sugar levels after dairy intake. If your glucose rises, the cause is the carbohydrate load from the dairy product. Strategies include: • choosing dairy with lower lactose or total carbohydrate (plain Greek yogurt, strained curd, paneer, cheese); • using smaller portions and pairing with protein, fiber, or healthy fat to blunt the glycemic response; • selecting lactose‑free milk, which still contains similar carbohydrate content but may be easier on the gut; • monitoring your glucose 12 hours after the dairy serving with a meter or CGM to see the actual impact and adjust portion size or product choice. In short, lactase tablets will not control the blood‑sugar spike; manage the carbohydrate content and timing instead.
