SOUND FAMILIAR?
Your last checkup came with a number to watch
Your doctor said not to worry yet. Just keep an eye on it. But watching isn't a plan, and that number has a way of creeping up while you wait.
THE CHECKUP
THE AFTERNOON SLUMP
THE LATE-NIGHT RESEARCH
Real Stories, Real Results
Excellent 4.7 / 5
IT'S NOT YOUR WILLPOWER
You're doing the work. Your body changed the rules.
You walk more. You cut back on carbs. You read every label. And it still feels harder than it used to.
That isn't a lack of discipline. Metabolism naturally changes as we get older, and the habits that used to be enough often need a little extra support.†
WHY BERBERINE
One plant compound. Centuries of use. Decades of research.
Berberine is a natural compound found in the bark and roots of plants like barberry. It isn't a social media trend. It's a well-studied ingredient that fits into a routine of balanced meals and regular activity.
Centuries of traditional use
Berberine-rich plants like barberry have been part of traditional herbal practice for generations.
Decades of modern research
Today berberine is one of the most studied botanicals for metabolic health.†
Supports healthy glucose metabolism†
Including healthy blood sugar and cholesterol levels already within the normal range.†
THE ABSORPTION PROBLEM
Why so much berberine never gets to work
Here's what most labels won't tell you: berberine is famously hard for the body to absorb. Research shows only a small fraction of what you swallow reaches your bloodstream. Your gut pushes much of it right back out, like a bouncer at the door.
That may be why so many people try berberine and feel like nothing happened.
So we built Rayo around a simple routine: two capsules, made with olive oil, taken with a meal. Taking berberine with food is the most common recommendation, and it's exactly how Rayo is designed to be used.

YOUR DAILY ROUTINE
Two capsules. One meal. That's the whole routine.
No powders to measure, no bitter taste, no complicated schedule. Take your capsules with a meal you already eat every day, and let consistency do the rest.
WHAT TO EXPECT
Your first 90 days
Berberine works gradually. Here's how to build the routine, one step at a time.
-
WEEK 1
Start the routine
Take 2 capsules with your largest meal each day.
Some people start with 1 capsule for the first few days to see how their stomach responds.
-
WEEKS 2 TO 4
Make it a habit
Consistency matters most. Pair your capsules with a meal you already eat every day.
Tip: keep the bottle where you eat, not in the medicine cabinet.
-
MONTHS 2 TO 3
Give it time
Most berberine research looks at 8 to 12 weeks of consistent daily use.
That is why many people choose the 90 Day Supply. Individual results vary.

IS IT RIGHT FOR YOU?
Made for people who are ready to act, not just watch
Talk to your doctor first if you take medication (especially for blood sugar), have a medical condition, or are pregnant or nursing.
WHY IT MATTERS
It's not really about a number
It's about the life around it. Staying active, staying independent, and being there for the people who count on you.
Capsules vs. loose berberine powder
Berberine powder is the raw ingredient, and it's famously bitter. Here's why we put it in a pre-measured capsule.
| Rayo Supply | Loose powder | |
|---|---|---|
| Pre-measured serving, nothing to weigh | ||
| Made with olive oil | ||
| No bitter taste | ||
| No mixing or measuring | ||
| Easy to take on the go |
