FitLine is a premium nutritional supplement brand from PM-International, a German company founded in 1993. What truly sets FitLine apart is its proprietary Nutrient Transport Concept, or NTC®, which is the core of its entire product philosophy.

FitLine operates with the motto "Experience Results," positioning itself as a science-driven company that blends traditional wellness with modern technology. The brand offers a wide range of products for health, fitness, and beauty, all designed to support an active and healthy lifestyle.

The company has built a strong reputation in the athletic community. Over 1,000 professional athletes reportedly use FitLine products daily, including partnerships with major sports organizations and individual athletes from various disciplines, such as Olympic competitors and professional soccer players.

The Nutrient Transport Concept (NTC®) is PM-International's exclusive, patented technology that forms the foundation of all FitLine products. According to the company, NTC® is designed to deliver nutrients "when they are needed, where they are needed – to the cellular level from inside and outside."

Traditional supplements often struggle with bioavailability—the degree to which nutrients can be absorbed by the body. Many vitamins and minerals pass through the digestive system without being fully utilized. FitLine claims that its NTC® technology solves this problem.

The NTC® system includes a "MicroSolve Technology," which is designed to enhance the bioavailability of nutrients. This technology allegedly works by optimizing the timing and location of nutrient delivery, ensuring vitamins, minerals, and other compounds reach the cells that need them most.

The Nutrient Transport Concept works on three main principles:

PM-International collaborates with several research institutions, including the Luxembourg Institute of Science and Technology (LIST). They have also established an endowed professorship for bioavailability at the University of Applied Sciences Upper Austria, showing their commitment to research.

However, it's worth noting that independent, peer-reviewed studies specifically validating NTC® technology are limited in publicly available scientific literature. Most of the evidence supporting the technology comes from the company's own research.

For consumers, understanding NTC® is key because it represents the main value proposition that justifies the premium price of FitLine supplements. The technology is presented as the key difference that makes FitLine products more effective than standard vitamins and minerals.

This concept appeals to health-conscious consumers who are tired of traditional supplements that don’t seem to work. By promising enhanced bioavailability and targeted delivery, FitLine positions itself as a solution for people who want to get the most value from their supplement investment.

Whether NTC® technology lives up to its promises is still a topic of discussion, but there is no doubt that it is an innovative approach to solving a major challenge in nutritional supplementation: making sure the nutrients we consume actually reach the cells where they can do the most good.
