The Science

The Art of Sleep, Mastered by Science.

The science of sleep is complex. We've created an intelligent solution respecting that. We're moving beyond single-ingredient solutions to create a comprehensive, multi-pathway formula that works in synergy with your body's natural sleep processes. We pair the wisdom of nature with the precision of science to support the entire sleep process and deliver a truly restorative night's sleep.


Our Commitment to Quality & Testing

A scientifically sound formula is only as good as the quality of its ingredients and the standards of its production. We believe that complete transparency is the cornerstone of trust, and we are committed to upholding the highest possible standards for every shot of renightalize.

Our commitment is built on three core principles:

1) Ingredient Purity & Potency

We source every raw material from a vetted, trusted supplier who can provide a Certificate of Analysis for each batch. This ensures that our ingredients are not only pure but also meet the exact potency specified in our formula.

2) Independent Third-Party Testing

We test every finished batch of renightalize at an independent, third-party laboratory here in the UK. This verification step ensures that the product you receive is free from heavy metals, microbes, and other contaminants, and that what's on the label is what's in the bottle.

3) UK Manufacturing Excellence

We are proud to produce our product in a state-of-the-art facility in the United Kingdom that is fully certified for both GMP (Good Manufacturing Practice) and BRCGS (Brand Reputation Compliance Global Standards), the gold standard for food safety and quality.
