At Quality of Life®, we don't ask you to take our supplements on faith. Because faith is irrelevant when you have research.

As a company committed to developing evidence-based products, Quality of Life® is the only company in the nutritional supplement industry willing to make you this promise:

Every single ingredient in every one of our products is backed by human studies and delivered in doses consistent with clinical research. 

No exceptions, no compromises.

Why are human clinical studies important?

Test tube studies are good for identifying promising ingredients. Animal studies test how well promising ingredients perform in a living system. Both are important steps in the research process.

But until an ingredient is tested in human clinical studies, there are no guarantees it will be effective in humans. In fact, most potential new drugs that are effective in animals end up failing in humans. That’s because humans differ from animals in anatomy, physiology, and metabolism.

Why do doses matter?

Everyone knows blueberries are a healthy food. Multiple human clinical studies, using about 1 cup per day (about 65-75 berries), have proven this fact. But what if, in the hopes of getting healthier, you decided to eat a single blueberry a day? Would you expect it to have any beneficial impact on your health?

This may seem like an extreme example, but it’s common for supplements to include ingredients at just a tiny fraction of the clinically studied dose, a practice known as “fairy dusting.” It may look good on the label, but it’s not doing you any good.

Proven Science for Real Results

When you choose Quality of Life, you can trust our supplements to do what they’re supposed to, because we only use clinically validated ingredients at the researched doses.
