Supplements Held to a Higher Standard

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.

We recommend showing your doctor or pharmacist the full ingredient label of any product you're considering — every label is available on each product page.

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.

It varies by product and by person. Some customers notice changes within the first few weeks, while other ingredients build their benefits with consistent daily use over two to three months.

We recommend giving any supplement at least 3–6 months — each product page explains what to realistically expect, and when.

Then you get your money back. Every order is covered by our 90-day money-back guarantee — it applies even on opened bottles, and less than 2% of customers ever claim it.
