What’s Inside the Gut Health Protocol
Your gut is an ecosystem — this protocol supports the flora, the metabolism, and the lining.
Microbiome Balance
Probiotic 60 Billion
A cellular sparkplug for your gut. This blend of beneficial bacteria is essential for replenishing your microbiome, supporting nutrient absorption, and promoting robust digestive health and regularity.
Metabolic Support
Berberine
Known for its powerful metabolic support. It helps promote healthy blood sugar balance, supports normal glucose metabolism, and maintains overall metabolic health—making it an essential ally for long-term wellness.
Gut Lining Support
NAC
A precursor to the body's "master antioxidant," Glutathione. NAC is rich in compounds that help support the body's natural detoxification processes and protect the cells of the gut lining from oxidative stress, promoting a stronger, healthier gut.
Why These Three Work Together
A healthy gut needs balanced flora, a supported metabolism, and a resilient lining. The probiotic seeds the ecosystem, berberine supports the metabolic environment, and NAC supports the barrier that holds it all together.
What Sets Our Gut Health Protocol Apart?
Gut health is an ecosystem. Treat it like one.
Synergy by Design
Microbiome balance (probiotics), metabolic support (berberine), and gut-lining support (NAC) — one system.
Meaningful Doses
60 billion CFU, 1,200mg berberine, and 600mg NAC daily.
Third-Party Tested
Every batch of every bottle is independently tested for purity and potency, and manufactured in a GMP, FDA-registered US facility.
Veteran-Owned. Made in the USA.
Luma Nutrition was founded by a U.S. Army veteran. Every product is formulated and bottled in the USA — because where your supplements come from matters.

Founded By a U.S. Army Veteran
I served four years as a U.S. Army Infantry Officer. The Army taught me one lesson I’ve never let go of: you never cut corners on the people counting on you.
That’s why I started Luma Nutrition — real clinical doses, independently tested, made in the USA. Nothing goes in these bottles that I wouldn’t hand to my own parents.
If you ever have a question about our products, reach out. I read and respond personally.

Claims Are Easy. Here’s Our Evidence.
Most supplement brands ask you to take their word for it. We’d rather show you.
Proof 1
Clinically Dosed. Not Under-Dosed.
Every Luma supplement uses clinically studied dosages, not the watered-down amounts found in most brands. What’s on the label is what’s in the bottle.
Proof 2
Third-Party Tested. Every Single Batch.
An independent certified lab tests every batch for purity, potency, and absence of harmful contaminants like heavy metals and bacteria. No shortcuts.
Proof 3
Veteran-Owned. American-Made.
Founded by a US Army Infantry Officer, Luma is made in FDA-registered, NSF GMP-certified facilities in the USA. Quality isn’t a marketing claim, it’s how we operate.
Proof 4
We Take the Risk, Not You.
Every order is covered by a 90-day money-back guarantee — even if the bottles are empty. A company that cuts corners couldn’t afford to make that offer.
