I've tried other things. Why GUT?+
Because you don't have to choose: GUT combines digestive enzymes, a probiotic and a prebiotic fiber in one formula, with every ingredient and its amount in plain sight. And if you don't love it, your first bottle has a 30-day guarantee from delivery.
What does it cost per day?+
GUT is $29.90 your first month (about $1.00 per serving), then $49.90/month (about $1.66 per serving). Save $35 on the first order versus the $64.90 one-time purchase. Based on 30 servings; excludes shipping and taxes.
What does it taste like? Are the capsules big?+
They're vegetable capsules you swallow with water: no powders, nothing to mix. If swallowing is hard, take one, sip some water, then the other.
