Why VESIsorb®

When VESIsorb® is applied to fat-soluble nutrients, it makes it much easier for the body to absorb. This technology has set a new benchmark for the industry.

We overcome bioavailability issues with ubiquinol by combining it with the novel, patented VESIsorb® delivery system that mimics the body’s natural uptake mechanism, therefore achieving nice plasma levels of CoQ10.

Dr. Nina Bailey

We look for technologies and ingredients that have outstanding scientific evidence. After all, a physician’s entire reputation is on the line when recommending professional dietary supplements like those with the VESIsorb® technology.

There is a really important technology called VESIsorb®, and this is the most advanced technology of receiving coenzyme Q10 in the supplement form.

Dr. Chad Larson
Healthcare Practitioner

By incorporating the VESIsorb® water soluble droplet delivery system, customers only need one soft gel compared to six of the competitor’s to equal the amount absorbed by the body.

Enhanced Bioavailability

As a lipid-based formula, VESIsorb® naturally self-assembles on contact with an aqueous phase into a colloidal system (also called “association colloid”) that mimics the physiological mixed micellar absorption pathway.


Markets Served

VESIsorb® has made a positive impact in multiple markets, taking absorption and bioavailability to new levels that dramatically exceed industry standards. This allows for an unmatched range of applications and product formulations. It has successfully been applied to the most popular science-backed bioactive ingredients like concentrated omega-3 EFAs, coenzyme Q10, QH ubiquinol Q10, vitamin K2, curcumin, phytocannabinoids, vitamin D, pterostilbene, palm tocotrienols, diindolylmethane (DIM), gamma tocopherols, citrus polymethoxylated flavones (PMFs), resVida®, resveratrol, krill oil, algal DHA, vitamin A (retinoids), phospholipids and beta-caryophyllene, among others.

Nutritional Supplements

In a market increasingly driven by knowledgeable people who take more control over their own health, consumers demand the highest quality from the science-based nutritional supplements they buy.

Food & Beverage

Consumers have discovered that adding quality supplements to their food and beverages is a highly desirable and effective means of adding nutrition to their diets.

Medical Foods

Physicians prefer medical foods with precise dosing and superior efficacy that are formulated with strict nutritional requirements for the specific dietary management of a disease or condition.


Consumers are moving toward more natural approaches for improving their hair, skin and body due to reports of the ill-effects of some chemically-based cosmetic products.

Animal Nutrition

Pet owners are increasingly interested in animal nutrition and health, and want the best science-based products for their pets, livestock, poultry and specialty species.


Bioavailability is one of the essential tools in pharmaceutical drug development as the absorption rate is a measurement of the drug formulation's ability to deliver its bioactives to the target site.

Who We Are

In 2007, Vesifact AG (Baar, Switzerland) and SourceOne Global Partners (Chicago, IL USA) formed a strategic alliance with the vision to bring new levels of bio-enhanced formulas to the natural products industry. A spin-off of the Federal Institute of Technology in Zurich, Vesifact developed VESIsorb® while SourceOne, a leading provider of health and wellness solutions, serves as the exclusive worldwide distribution and marketing partner.

Throughout the past ten years, the two companies have successfully brought to market more than 50 VESIsorb® formulations that have safely and effectively served close to 200,000,000 million consumers around the world.
