The Previnex Promise: How We Source, Manufacture, and Test Our Supplements

Most supplement companies aren't required to tell you how their products are made. At Previnex®, we publish the details anyway, because pharmaceutical-grade quality only means something when you can see exactly what goes into our products.

When it comes to supplements, it’s important to know not just what’s in them, but where those ingredients come from, how they’re processed, how they’re tested, and how they’re produced.

Previnex® prides ourselves on only putting the highest quality, safest, and most clinically effective ingredients into our supplements. You deserve a transparent supplement company you can truly trust, so let's walk through our sourcing, manufacturing, testing, and production guidelines and processes.

Not only do we source the highest quality ingredients on the market, but on top of that, in every case we can, we’re using ingredients that have undergone human clinical studies to prove their effectiveness.

One example of how we source our ingredients is in our Omega Pure PLUS® supplement (fish oil). For these, we only source wild species of anchovies, mackerels, and sardines from the most omega-dense regions in the world, and we actually have fishing zone maps that show where we source. This helps us remain above board and ensures that we’re partnering with only top, ethical harvesters of these fish species.

Another example is Joint Health PLUS®, which consists of two main active ingredients, NEM® and Boswellin®, both of which have undergone human clinical studies. NEM® is clinically proven to be up to 5x more effective and beneficial than glucosamine and chondroitin alone or in combination, giving your joints the best protection available. Boswellin® is a clinically proven natural anti-inflammatory and pain reliever, providing joint relief in a more natural form. 

Another important aspect of our approach to ingredients is where we source from. For our Nourify® PLUS protein powder and meal replacement shakes, we source our pea protein from a farm in Canada that follows organic farming practices and our brown rice protein from high-quality farms in Southeast Asia. Many manufacturers source from China to keep costs down, but due to high levels of pollution and soil contamination and a lack of quality assurance protocols, Previnex® avoids sourcing from China.

For the grape seed extract in our Previnex® Multivitamin, Mineral & Antioxidant PLUS, we source from regions of Austria and Switzerland that have the highest quality grape seed extract on the planet.

You get the idea. We go above and beyond because that's what we'd want as customers, and that's what you deserve.

Pharmaceutical-grade manufacturing follows stricter safety protocols than food-grade, including ingredient testing, production run testing, and finished product testing at every stage. At Previnex®, that's the standard we hold ourselves to for every batch.

You may already be aware that food-grade manufacturing is less highly-regulated compared to pharmaceutical-grade manufacturing. So it might be confusing to see the word “pharmaceutical” used to describe supplements like ours.

Here's what we mean by "pharmaceutical grade": We believe all supplements  should undergo the same manufacturing scrutiny as pharmaceuticals, so that's the standard we use here at Previnex®. It's a much more precise standard that has safety protocols built into for ingredient testing, production run testing, and finished product testing. All to ensure we’re giving you the safest, highest quality product on the market.

Every ingredient that comes through our door is tested for contaminants, metals, microbials, etc. We even have agreements with our raw material suppliers that if an ingredient fails raw material testing, they are responsible to get the ingredient, send us a new product to test, and fix the issue. In our (almost) 11-year history, we have only had one experience—during COVID—where an ingredient failed microbial testing. It failed on account of mold, which triggered an ingredient return and new product being sent out to us, and the new product passed testing with flying colors. If we were a manufacturer that skipped these testing and safety protocols, then a moldy ingredient would have been baked into the product (gross).

During the manufacturing runs of each and every product, we pull product aside to perform US Pharmacopeia testing for product stability, hardness, thickness, dissolution, disintegration, etc. If it doesn't dissolve within 45 minutes, that means it will pass the small intestine before nutrients can be absorbed. Our tablets, capsules, and softgels dissolve in an average of 20 minutes, and we have the data to back it up. What this means is that with Previnex®, you know you’re getting products that are breaking down (well) in time to deliver all the benefits.

Once raw ingredient and production run tests are complete, we take the final steps of testing the finished products. Here, we generate Certificates of Analysis for each product during every production run. This finished product testing ensures that every single thing you read on the label is exactly what’s in the product—and if it’s not on the label, it’s not in the supplement.

Clinically tested means every ingredient we use, wherever possible, has been validated through human clinical trials, so that we can formulate based on data.

For example, with our Previnex Probiotic®, you’ll see a registered trademark next to every strain of health bacteria. The same is true of the prebiotic we use, NutraFlora®, which is clinically proven to help with the growth and colonization of the healthy bacteria in the gut. It's the very best prebiotic we could find on the market, based on all of the available data.

These standards are not very common in the supplement industry, where predatory and exploitative practices are common. That just makes them even more important to us at Previnex®. We aim to take the guesswork out of supplementing and produce the best, safest, and most clinically effective product to benefit your health. We will go the extra mile every time to make sure we deliver.

We promise to never give you anything but the best we can find. We will always source the highest quality ingredients, test every one of those ingredients, and test every single product before it hits our site. What you see on the label of your product is exactly what you’re getting—we don’t hide ingredients or chemicals, and we never sneak in any filler or fluff.

We take our responsibilities as a supplement company seriously, because we care so deeply about our community's health. We want you to flourish and live the longest, healthiest, most active life possible. And when they're done right, supplements can help you do it.

At Previnex®, everything we do is driven by science and held to the highest standard in the industry. If you’re ready to take the next step on your health journey, you can find our products here.
