The Science Behind It

Vitamin B12 sits at the center of energy metabolism — your body needs it to turn food into fuel, build red blood cells, and keep nerves healthy.

B12 comes almost entirely from animal foods, and absorption declines with age — which is why low B12 is one of the most common (and most missed) nutrient gaps.

If you’re low, B12 is one of the faster supplements to feel — energy support often shows within the first few weeks.*

How to Take

Take 1 capsule daily, morning is best — B12 supports energy, and you want that working during the day.

Each bottle is a full 60-day supply.

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 vitamin B12 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.

B12 is water-soluble and very well-tolerated. If you’re pregnant, nursing, or managing a medical condition, we recommend consulting your healthcare provider — just to be safe.

Most B12 never gets absorbed.

The cheap form your body struggles to use.

Cheap forms

Many bottles use the cheapest B12 form at token doses. Ours delivers a full dose your body can actually put to work.

Hidden blends

Proprietary blends let a brand list an ingredient while telling you nothing about how much is actually inside each capsule.

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.

How long until I see results?

This one builds with consistent daily use rather than hitting all at once. Typical, not guaranteed — which is why the guarantee runs 90 days.

Week 1–2 Energy first

If you were low, energy is usually the first thing to respond.

Week 2–4 Clearer days

Focus and afternoon stamina steady out with daily use.

Week 4+ The new baseline

Consistent B12 keeps the tank full — simple as that.

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?

If you're low on B12, energy support often shows within the first two to three weeks — it's one of the faster vitamins to feel.

How do I take it?

One serving daily. The full serving size is on the label — consistency matters more than timing.

Can I take this with my prescriptions?

B12 is generally safe alongside most medications. If you're managing a condition, your doctor may actually want to know your B12 status — ask at your next visit.

How is this different from a cheaper version?

Form and dose. Many bottles use the cheapest form at token amounts; ours delivers a full dose, stated plainly, with a published lab report for every lot.

Is it made in the USA and tested?

Yes — made in FDA-registered, GMP-certified U.S. facilities, and every batch is tested by an independent ISO 17025-accredited lab. We publish every result.

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.
