Buying advice

When choosing a lactase supplement consider the enzyme potency (FCC units), dosage timing, and any dietary restrictions. Higher-dose tablets are useful for dairy-heavy meals, while chewable or fast-acting forms are convenient for on-the-go. Balance price with potency and look for vegan or allergen-free labels if needed.
