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
WHAT → WHEN → WHERE
WHEN
Formulas are designed around different moments and uses in the daily routine.
WHERE
The NTC® concept focuses on making nutrients available where the body needs them.
A COORDINATED SYSTEM
NTC® works within a system, not in isolation.
Different FitLine products are designed for different moments and purposes. The NTC® concept helps connect those formulas into a recognizable daily product system. No one needs to buy every product.

INNOVATION & QUALITY
Technology needs a quality system behind it.
German production
FitLine reports German production and controls from raw-material selection through the finished product.
GMP
GMP concerns manufacturing quality standards, not a guarantee of a personal result.
ELAB
FitLine reports regular independent product testing by ELAB Analytik GmbH. It does not validate every marketing interpretation.
Cologne List®
For applicable sports products, listing relates to testing for selected prohibited substances—not general clinical effectiveness.
Innovation protected by an extensive patent portfolio.
FitLine states that its product concept and related technologies are supported by a portfolio of more than 100 patents.

FitLine reports continuing collaboration with LIST and the University of Applied Sciences Upper Austria, plus an endowed professorship for bioavailability established in 2024.
These institutions are not presented as endorsing every product.PRODUCT TECHNOLOGIES

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.
