The Science Behind It

Your gut is home to trillions of bacteria that influence digestion, immunity, and even mood. A daily probiotic helps keep that ecosystem in balance — especially after antibiotics, travel, or a processed-food stretch.

Each serving delivers 60 billion CFU of live cultures — a serious daily dose, stated plainly on the label, not a “blend” hiding a sprinkle.

Probiotics work as they colonize — most people notice digestive comfort within 2–4 weeks of consistent daily use.*

How to Take

Take 1 capsule daily, with or without food. Same time each day helps your gut establish a rhythm.

If you're taking antibiotics, space your probiotic a few hours away from the antibiotic dose.

Shipping & Returns

We offer tracked shipping on all orders, processed within 24 business hours on weekdays.

U.S. orders typically arrive in 3–5 days. Shipping is free on subscriptions and on one-time orders over $50.

Returns are easy. Every order is covered by our 90-day money-back guarantee — email help@lumanutrition.com and we’ll handle everything.

Is It Safe?

Yes — our probiotic is made in FDA-registered, GMP-certified U.S. facilities with no proprietary blends. Every batch is third-party tested for purity and potency by an independent ISO 17025-accredited lab.

Probiotics are generally very well-tolerated — some people notice mild bloating the first few days as the gut adjusts, which typically passes. If you’re pregnant, nursing, or immunocompromised, we recommend consulting your healthcare provider before use — just to be safe.

Ingredients

A proprietary 5-strain, 60 Billion CFU probiotic blend (600 mg) per 1-capsule serving, including L. paracasei, L. plantarum, L. acidophilus, and B. lactis.

No artificial dyes or preservatives. Made in FDA-registered, GMP-certified U.S. facilities.

3rd-Party Testing

Every batch is tested by an independent ISO 17025-accredited lab — potency, heavy metals, and microbiology. We publish every result. Click here.

Bloating after meals, unpredictable digestion, getting run-down easily — your gut touches all of it. A serious daily probiotic is the first thing worth ruling out.

The most common report: less bloating and a calmer, more predictable gut.

Immune support

A large share of your immune system lives in your gut — balance helps it work.

Most probiotics never survive the trip.

Stop paying for cultures that are dead on arrival.

Weak doses

Many bottles deliver 1–10 billion CFU. We deliver 60 billion per serving — stated on the label, not buried in a blend.

Hidden blends

“Probiotic blend” labels can hide how little of each strain you're actually getting. Ours states what's inside, plainly.

Untested

Many brands claim third-party tested. Can they prove it? Ask them for a result. We post ours freely. Click here.

We built this bottle 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. We publish the results of all third-party testing.

Jake Langley, founder of Luma Nutrition

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.

Questions before you order.

How long until I see results?

Some people feel a difference in days; for most, digestive comfort builds over two to four weeks of consistent daily use as the cultures colonize.

How do I take it?

One serving daily, with or without food. The full serving size is on the label. Consistency matters more than timing.

Will it cause bloating?

A few people notice mild bloating in the first few days as the gut adjusts — it typically passes within a week. If it persists, reach out and we'll help.

Can I take this with my prescriptions?

Probiotics are generally safe alongside most medications. If you're immunocompromised or on long-term antibiotics, check with your doctor first — and space probiotics a few hours from antibiotic doses.

How is this different from a cheaper probiotic?

Dose and honesty. Many bottles deliver 1–10 billion CFU or hide behind blend labels; ours delivers 60 billion CFU per serving, stated plainly, with a published lab report for every lot.

What if it does not work for me?

You get your money back. The whole order, empty bottles included, for 90 days. No forms and no restocking fee.

Real customers, real results.
