Frequently Asked Questions

Does Delta contain melatonin?
No, Delta does not contain melatonin.

We believe that our brains should decide how much melatonin they need to create natural sleep.

Therefore, Delta contains the natural precursor of melatonin: tryptophan. If you take Delta, your brain will use the appropriate amount of tryptophan to produce melatonin naturally.
Is Delta FDA-approved?
The FDA does not approve dietary supplements, but rather regulates them as food products. The Delta formula and label follow FDA guidelines.
