Our Quality Commitment: Proven Ingredients

You want evidence-based formulations that are proven safe and effective. Lucky for us, that’s kind of our specialty.

Within the supplements industry, most manufacturers fall into one of three categories


Manufacturers in the first category use proven ingredients that are considered industry leaders because of their impressive clinical pedigree and exceptional safety profiles.


Manufacturers in the second category use commodity ingredients that are similar to, but not the same as, proven ingredients and rely on borrowed science to market the product; this involves taking the results of a clinically proven ingredient or product and using it to sell unproven, sometimes unsafe, products.


Manufacturers in the third category use ingredients that are often unknown and mostly unproven and hype up the ingredient’s benefits using marketing science.

At NutriGold we know that every time you purchase one of our products, you are entrusting us with your most prized possession, your health, and this is not a responsibility we take lightly.

So, we look past all the marketing hype, reject the temptation to cut corners or use inferior quality ingredients, and rely on a combination of historical evidence and scientific data to identify ingredients that are proven to be both safe and effective. To settle for anything less would not only be a violation of the trust you have in our company and products but a betrayal of our fundamental commitment to “do no harm.”

The ingredients featured in our products read like a list of “WHO’S WHO” in the nutraceutical industry. Go ahead and stare all you want—they are used to the attention.

Kaneka Q10®, the only CoQ10 manufactured in the U.S., is the world’s purest, most thoroughly researched CoQ10 ingredient available today. Unlike many CoQ10 ingredients that are processed from bacteria or tobacco leaves, Kaneka Q10 is fermented from pure, natural yeast and does not contain the impurities that synthetically processed CoQ10 does. Kaneka Q10® is bio-identical to the CoQ10 produced by the body and helps support cellular energy, stamina, endurance, and overall wellness.
