Buying advice

When choosing a lactose intolerance medicine, consider the severity of your symptoms, the amount of dairy you typically consume, and your budget. Products with higher FCC units are better for heavy dairy meals. For occasional mild symptoms, lower potency options like Lactaid or Kirkland are cost-effective. Always check for allergens and consult a healthcare provider if symptoms persist.
