After 40, the Belly Changed the Rules. You Can Change Them Back.

The menopause middle isn't a character flaw and it isn't permanent. When your hormones shifted, they quietly reprogrammed your gut to store fat at your waist — so no diet touched it. Rebalance the gut, and your body can start working with you again.

It Was Never Willpower. It Was Your Hormones.

As estrogen drops in perimenopause and menopause, your metabolism slows and the balance of bacteria in your gut falls out of sync with your hormones — telling your body to store fat right at your midsection.

That’s why ‘eat less, move more’ stopped working: it’s aimed at willpower, when the real lever is the gut underneath it.

Mary Lincoln “Great for reducing bloating!”

I am almost done with my fourth bottle. I started out taking twice the recommended dose just to jump start things, then went to the recommended dosage after I finished the first bottle. I've definitely noticed less bloating. I feel slimmer and have been told I look thinner. I've lost a couple of pounds, but not many.

Anonymous “Probiotics for weight management has helped me with the hunger”

Probiotics for weight management has helped me with the hunger. I eat once a day (dinner) and I haven’t been hungry at all. Last night I even ate half my dinner, took the dog out and when I came back I dumped the rest of dinner because my stomach was full. I was on the shots for two years and my insurance stopped covering them and the weight came flying back on very quickly, which is why I tried this and the hunger noise is going quiet finally.

Why This Works When Diets Didn't

This isn't another supplement that does nothing. It's a precision tool built for exactly this stage of life.

greater reduction vs. placebo in a 6-month human study (N=225).* 92% of women 45+ reported feeling better about their belly area after 3–6 months.

Choose the Plan Built to Actually Work

B420's results were measured over months, not days — so a single bottle can't tell you if it's working. The 3-month plan is the shortest honest test, which is why it's our clinically recommended starting point.
