The Science Behind It
Your microbiome, metabolism and gut lining move independently — covering one doesn't cover the other two. That is the entire reason these three formulas are taken together.
Probiotic (5-strain blend) — restocks the good bacteria. Berberine (1,200 mg) — supports the gut-metabolism axis. NAC (600 mg) — supports the gut's protective layer.
No proprietary blends where it matters and nothing watered down — every formula at a meaningful, research-informed dose.

Is It Safe?
One real interaction to know: berberine can amplify the effect of diabetes medication. If you take glucose-lowering medication, talk to your doctor before starting.
If you are immunocompromised, check with your doctor before adding a probiotic. Do not take berberine while pregnant or nursing.
Managing a condition? Check with your healthcare provider first — just to be safe.

Complete gut support takes all three.
Your microbiome, metabolism and gut lining move independently — covering one doesn't cover the other two. That's why these three come in one box.

★★★★★ Verified buyers of the three formulas in this protocol
“My experience with this probiotic has been better than expected. I have been using for about a month with a noticeable difference in my gut health.”
“Been using Berberine for over five years now. It has help keep my Diabetes and High Blood Pressure in check along with my prescription medications. Very high quality product.”
“It seems to be a good product. I have been taking it for a week now and it seem to be helping in all aspects.”
We built this protocol to a higher standard. Here’s the proof.
Premium quality for a fair price. The Luma 4-Point Verification checks potency, purity, microbiology and identity confirmation on every batch of all three bottles — three bottles, three certificates. We publish the results of all third-party testing.
Why the Gut Protocol is better.
Trusted by world-class medical professionals.
“Quality ingredients, appropriate dosing, thoughtful formulations. I’m comfortable recommending them to patients.”
“What I really love about Luma Nutrition is how dedicated they are to purity, proper dosing, and smart formulation.”
“These aren’t just pretty labels. They really deliver. The dosing is where most brands quietly cut corners.”
These practitioners partner with Luma Nutrition as paid ambassadors, sharing their own opinions and experience.
I couldn’t find a brand I trusted. So I built one.
It started with a supplement I almost bought for my parents. The label looked impressive. But I couldn’t find any test results, and the dose was a fraction of what the research used.
The Army drilled honor and integrity into me. You don’t cut corners when people are counting on you. The supplement industry cut them everywhere I looked.
So I built Luma to a higher standard: meaningful doses, independent testing on every batch, and verified results anyone can see.
Nothing goes in these bottles that I wouldn’t give my family or take myself. We’ll never ask you to trust a claim we aren’t willing to prove.
Questions? Reach out. I read and answer them.
