Most of our supplements work on two timeframes. You'll often notice subtle effects within the first 1–2 weeks – better energy, sharper focus, smoother digestion, depending on the product. The deeper benefits build over 30 to 60 days of consistent daily use, as your body restores nutrient levels and adapts to the support.

Supplements aren't medications. They work best as part of a daily routine, alongside good sleep, hydration, and nutrition. If you don't feel a difference after 60 days, our money-back guarantee has you covered.

Yes. Every batch is independently tested by accredited third-party labs for purity, potency, and heavy metals (lead, arsenic, cadmium, mercury). We test for what we claim is in the bottle, and we test for what shouldn't be.

Certificates of analysis are available on request – email hello@restologylabs.com with the batch number from your bottle. If a product ever fails testing, that batch doesn't ship.

We offer a 60-day money-back guarantee on every order. If you don't love your purchase – for any reason – let us know within 60 days of delivery and we'll refund you. You don't need to send the product back.

To start a return, email us at hello@restologylabs.com (or use the contact form) with your order number.
