Frequently Asked Questions

Everyone is different, and results vary. Some customers notice a difference within the first several weeks, but the best results come from consistent daily use over time — we recommend giving any supplement at least 3 to 6 months, paired with a healthy lifestyle.

That's why every order is covered by our 90-day money-back guarantee: if you're not happy for any reason, we'll refund you.

Our products are made with natural ingredients and are generally well tolerated. If you have a medical condition, take prescription medications, or are pregnant or nursing, talk with your doctor before starting any new supplement.

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.

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. Every product's full ingredient label is available on its product page.
