INGREDIENT-ONLY VIEW
Intake is not guaranteed availability
Availability varies with nutrient form, dose, formulation, food and individual factors; unabsorbed material continues through digestion.

NTC® — THE TECHNOLOGY BEHIND THE FITLINE SYSTEM
FitLine is not defined only by what is in the formula.
It is also defined by how the formula is designed to make nutrients available to the body.
FitLine describes its Exclusive Nutrient Transport Concept (NTC®) as delivering nutrients when and where they are needed, to the cellular level, from inside and outside.
This is attributed FitLine positioning. It does not mean guaranteed complete absorption or an identical result for every ingredient.A SIMPLE EXPLANATION
NTC®: It is not only what you take. It is what your body can use.

NTC® without overstatement
What does NTC® stand for?
NTC® stands for the Exclusive Nutrient Transport Concept, FitLine’s name for its product concept focused on when and where nutrients are made available.
Is NTC® an ingredient?
No. NTC® is a FitLine product and formulation concept, not a single vitamin, mineral or ingredient.
Is NTC® used in every FitLine product?
Current official FitLine product pages in this catalog include an NTC® section. Check the current market-specific product page because formulas and product positioning can change.
Is NTC® the same as MicroSolve®?
No. NTC® is the broader FitLine concept. MicroSolve® or MicroSolve+ is a separately named patented technology documented for specific products such as microSolve⁺ Heart Duo.
Does NTC® guarantee complete absorption?
No. Neither this site nor the official concept supports a promise of complete or identical absorption for every ingredient or person.
Why does FitLine emphasize timing?
Different products are positioned for different moments and purposes in a daily routine. Timing remains product-specific and should follow the current label.
What does “to the cellular level” mean?
This is part of FitLine’s official description of NTC®. We present it as brand positioning, not as an independently proven medical endpoint for every product.
Is NTC® independently tested?
Quality testing and a technology concept are different. FitLine reports independent ELAB product testing; that does not by itself validate every interpretation of NTC®.
What evidence supports each product?
Evidence varies by formula, ingredient, amount and intended use. Review the current product page and label rather than applying one general NTC® statement to every outcome.
