Formulation Philosophy

Have you ever wondered if the supplements you purchase actually work? With so many brands making so many promises, it's hard to know whom to trust.

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 that can make this guarantee:

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

No exceptions. No compromises.

Why Human Studies?

"Currently, nine out of ten experimental drugs fail in clinical studies because we cannot accurately predict how they will behave in people based on laboratory and animal studies."

-Mike Leavitt, U.S. Secretary of Health and Human Services

While test tube and animal studies may help identify promising ingredients worthy of further study, human clinical studies are widely considered the gold standard of scientific research. Why? It’s simply not possibly to make foolproof predictions about how any given substance will function in the human body from test tube or animal studies alone.

Humans differ from animals in anatomy, physiology, and metabolism. Consider these examples:

  • Chocolate is delicious to you, but poisonous to dogs.
  • Tylenol® is great for relieving your headache, but it’s toxic to cats.
  • Penicillin will help clear up your ear infection, but it will kill a guinea pig.

When you choose Quality of Life®, you can trust your supplements to work, because 100 percent of the ingredients in every product we manufacture are backed by human clinical studies.

 

Why Do Dosages Matter?

Everyone knows blueberries are a healthy food. Multiple human clinical studies, using about 1 cup per day (about 200 berries), have proven this fact. But what if, in the hopes of getting healthier, you decided to eat a single blueberry a day?

Common sense says that eating just one berry daily is unlikely to “keep the doctor away.” This observation is consistent with an accepted principle of both conventional and integrative medicine: Dosages matter. Many natural compounds have been shown to be effective at specific threshold doses, yet have little or no impact at lower ones. Just because eating a daily cup of blueberries is beneficial does not mean that eating one berry a day will have any effect.

Unfortunately, it is common practice in the nutritional supplement industry to use dosages of ingredients that are lower than those supported by clinical research.

When you choose Quality of Life®, you can trust your supplements to work, because 100 percent of the ingredients in every product we manufacture are provided in dosages that match the clinical research.
