Before And After Stories Directly From Our Customers

Amy B. Verified BuyerAge 44
★★★★★

Gentle but thorough

The oxygen-based formula works differently from harsh stimulant laxatives. Thorough, but without the cramping or urgency I have had from other products. It works gradually and predictably, so I can plan around it, and my regularity stayed better even after I finished the cycle.

★★★★★★

Start at two

A great product, but for me the recommended four capsules is far too much. One or two is plenty. I would start at two and see how you respond before going up.

★★★★★

Really works

Start with 2 and work your way up to 4 over the next few weeks. No taste, though the capsules are big. I am on my second bottle. It has definitely helped me debloat.

★★★★★★

Effective without stomach irritation

Very effective for occasional constipation and bloating. It works overnight and does not cause stomach irritation or acid reflux. Clean ingredients, and you can adjust the dose to what you need. I have it on auto-ship for my family. Well packaged in a dark glass bottle.
