Do I need a subscription to use Core100, or can I buy it once?

You do not need a subscription to use Core100.

You can purchase Core100 as a one-off 90-day protocol or as an ongoing subscription. A subscription simply makes it easier to stay consistent by ensuring your next bottle arrives before the current one runs out. You can pause, skip, or cancel from your account at any time; check the product page for the latest details.

What is your 90-day guarantee and how does it work?

Core100 is covered by a 90-day money-back guarantee so you can complete the full protocol with confidence.

If you don’t feel it’s a meaningful step for your energy and resilience by the end of that window, you can request a refund within 90 days of purchase, subject to our return policy. Full details, including eligibility and how to start a return, are outlined on our Guarantee & Returns page.

How do I start a return if Core100 isn’t right for me?

If you’d like to request a refund under the 90-day guarantee, start by visiting our Guarantee & Returns page.

There you’ll find a short form or contact method to submit your order details, including your order number and email address. Our team will review your request, confirm eligibility under the policy, and share next steps, including any instructions for returning unused product (if required) and timelines for processing your refund.

Do you ship Core100 to my country?
