Ingredient Sourcing

A supplement is only as effective as its underlying ingredients. That’s why we source the highest quality, most bioavailable, and clinically effective ingredients on the planet, regardless of their cost.

Clinically Tested &
Proven Ingredients

In every case we can, we use clinically tested and proven ingredients to ensure our products deliver the maximum health benefits possible. This means more expensive raw materials than generic and untested ingredients, but it’s worth the health benefits every time!

Optimal Forms
of Ingredients

Not all vitamins, minerals and antioxidants are the same. For example, there are different forms of Vitamin C, Vitamin B12, Folate, and so on. Most supplement companies use the cheapest, least effective forms of these ingredients, many of which are not bioavailable and don’t provide health benefits. At Previnex, we use the most optimal forms and amounts of key vitamins, minerals and antioxidants proven to tangibly benefit health.


The vast majority of supplement companies adhere to Food Grade Manufacturing protocols which comes with very little regulation. While not required in the supplement industry, we follow the more stringent manufacturing processes of the pharmaceutical industry, even when most other supplement companies choose not to follow suit.

Raw Material Testing

We test every raw ingredient used in our products for contaminants, bacteria, metals, microbials, and more, in order to ensure that you’re getting the cleanest, safest ingredients and products possible. Shockingly, this also is not required in the supplement industry.

Production Run

During the manufacturing process, we run tests on product dissolution, disintegration, stability, hardness, and thickness to ensure our products are going to do what they’re intended to do. Guess what? This also is not required in the supplement industry!

Finished Product

We test all finished products to make sure that what is on the label is in the bottle, and that what’s not on the label never will be in the bottle. You guessed it, also not required in the supplement industry!

Way More Benefits

Our goal is to disrupt an industry that for years has been preying on consumers with low quality products made with the cheapest, least effective ingredients! Behind every Previnex Product is a meticulous process designed to bring the safest, most effective, and highest quality products to market. Products that will tangibly benefit and optimize your health, and improve the quality of your life.
