Frequently Asked Questions

When it comes to your health, we believe there is nothing more important than transparency. We’re here to make sure you feel confident about your decision.
C15 Advantage contains a revolutionary blend of cellular superchargers: C15, CoQ10, Vitamin D3, Mediterranean Olive Fruit and Leaf Tri-Extract, and MCTs.
Gundry MD C15 Advantage is an energizing blend of “cellular superchargers” handpicked to invigorate your mind and body — including a newly discovered “essential superfat,” C15.†* This unique formula is designed to help your body defend itself against harmful compounds called aldehydes that can attack cells in your heart and brain to drain your energy, affect your mental processing, and disrupt your metabolism. By supporting your cells with C15 Advantage, you’re helping to energize and revitalize cells all over your body — so you can experience everything from more energy, to clearer thinking, to fewer visible wrinkles.†*

C15 Advantage™ combines the power of 5 elite mitochondrial boosters, designed to support the trillions of microscopic “powerhouses” fueling every cell of your body.†*

That includes cells in your heart and brain — which are especially vulnerable to harmful aldehyde compounds “hiding” in many common foods.

C15 Advantage supports your mitochondria’s ability to:

  • Create more energy
  • Repair damage from aldehydes
  • Expel energy-draining “cellular junk”
  • Keep cells youthful, strong, and healthy.

And that helps your heart, brain, muscles, bones, eyes operate at peak performance.†*

Individual bodies can react differently to the very same compounds. So even though we believe everyone can experience a boost to energy, mental clarity, and overall health from C15 Advantage™ — your results may vary. In the unlikely event you're not thrilled with this formula (for any reason whatsoever), just let us know within 90 days of use and we'll gladly refund your purchase price (minus shipping).
This potent blend of superfats is designed to provide a noticeable boost in physical energy, mental sharpness, and youthful vitality on the first day of use — as soon as an hour after taking C15 Advantage.†* However, users have confirmed the most dramatic health support to appear after steady use over the course of 4 weeks and beyond. Please use as directed.*
