Frequently Asked Questions
Who is Nathaly Marcus and why did she create Fortcore?
Nathaly Marcus is a clinical nutritionist and a pioneer in functional medicine with over 30 years of experience. As the founder of the Functional Health Mind-Body Institute, she has dedicated her career to finding the root causes of health issues rather than just treating symptoms. She created Fortcore to provide high-performance, science-backed supplements that meet the rigorous clinical standards she requires for her own patients.
What is the "3R Method" mentioned in the formulas?
The 3R Method is Nathaly Marcus’s signature framework for achieving total wellness:
Repair: Healing the gut and reducing systemic inflammation.
Regenerate: Revitalizing cellular energy and slowing the aging process.
Reset: Balancing metabolism and hormones to restore the body’s natural rhythm. Every Fortcore product is designed to support one or more of these pillars to help you move from simply "surviving" to thriving.
Why should I choose Fortcore over other supplement brands?
Fortcore isn't just another supplement line; it is a clinical-grade system. We prioritize high bioavailability, clinically backed dosages, and zero-sugar formulations. Our products are the exact tools Nathaly uses in her practice—clinically dosed and backed by peer-reviewed research.
Are Fortcore supplements safe to take together?
Yes. Our product ecosystem is designed to be synergistic. Many of our customers combine formulas (such as our Sugar Reset with NAD+) to address multiple pillars of health simultaneously. However, if you are pregnant, nursing, or taking prescription medication, we always recommend consulting with your healthcare provider first.
How soon can I expect to see results?
While many users feel a difference in energy and mental clarity within the first few days, cellular health is a marathon. For metabolic and hormonal support, we typically recommend consistent use for 30 to 90 days to allow your body to fully repair and regenerate.
What is your quality standard?
Quality is our obsession. All Fortcore products are manufactured in facilities following strict GMP (Good Manufacturing Practice) standards. Our ingredients are peer-reviewed for efficacy, sugar-free, and tested for purity to ensure you are getting exactly what is on the label.
Do you offer international shipping?
Yes! We ship to a wide range of countries, including Canada, Mexico, the UK, the European Union, Australia, and more. Shipping rates and delivery times are calculated at checkout based on your location.
What is your return policy?
We stand behind our formulas. If a product isn’t the right fit for you, we offer a "Satisfied or Refunded" guarantee. Please contact our support team within 30 days of your purchase, and we will guide you through the return process.
