Vital
Our verdict
A gentle, traditional-herb digestive formula with added enzymes. It may suit adults over 60 with occasional bloating, gas or heaviness after meals. The doses are small, so it works best alongside the basics: fiber, water and movement.

What is Integrative Digestive Formula?
Integrative Digestive Formula takes a different approach from a typical probiotic. It is based on Traditional Chinese and Ayurvedic "warming" herbs, plus a small blend of digestive enzymes and medicinal mushrooms. Our guide to digestion after 60 explains why digestion slows with age.

Amounts per herb are not listed within each blend, and the total herb content per capsule is modest.
Does it work? What the research says
Ginger and alpha-galactosidase have the clearest evidence among these ingredients. The rest are traditional remedies with limited modern research. The sales page promises that heartburn and constipation become "simply not possible"; that is not a realistic expectation from any supplement.
That said, many customers report less bloating and more comfortable digestion, and it is a gentle option to try under the 90-day guarantee if you have occasional symptoms.

Digestion after 60Frequently asked questions
What is Integrative Digestive Formula used for?
It is a herbal and enzyme formula meant to support comfortable digestion and help with occasional heartburn, indigestion, gas and bloating.
Can I take it with probiotics?
Yes, they work in different ways and are commonly combined.
Is it safe with medications?
The licorice is deglycyrrhizinated (DGL), which avoids the blood pressure effects of regular licorice. Still, check with your doctor or pharmacist if you take prescription medicines.
How quickly does it work?
The company says some people notice a difference the first day. Give it at least four weeks to judge it fairly.
