We Unconditionally Guarantee It for 365 Days

We understand you might be skeptical. How could reversing a magnesium deficiency — with 7 proven forms of this one nutrient — do so much?

You’ve seen the research.

Magnesium Breakthrough works. And by the time you read this, it will have already changed the lives of thousands of people.

Plus, our company — BiOptimizers — has been in business for 15 full years. We stand behind our products and guarantee that they will do what we say they do. 🌟

If you purchase 1 bottle and you are not completely satisfied, within 365 days you may request a full refund (minus shipping & handling cost).

If you choose to save money and buy a bundle of multiple bottles, you are still covered by a 365 day guarantee. If after your first bottle you are not satisfied, you can return your remaining unopened bottles within 365 days of purchase and we will issue you a full refund for your order (minus the cost of shipping & handling)*.

*Please note: If you open a second bottle, you no longer qualify for the guarantee above. Speak with our customer service team, and you may be able to receive a prorated refund depending upon the number of unopened bottles you will be returning.

Just contact us, let us know where we could be better, and we will issue you a refund (excluding any shipping and handling charges).

No questions asked.
