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.

FREQUENTLY ASKED QUESTIONS
Always check with your doctor or pharmacist first — they know your health history. Some ingredients can interact with prescription medications; for example, Nattokinase may interact with blood-thinning medications, so talk with your doctor before taking it if you use blood thinners or have an upcoming procedure. The full ingredient label is on this page under Ingredients.
Two things: dosing and testing. Many budget brands use a fraction of the ingredient amounts used in published research, and most are never tested by an independent lab. Every Luma formula uses full clinical doses of clinically studied ingredients, and every batch is tested by an independent lab for purity and potency.
