Training, nutrition, sleep and recovery are the foundation. Supplements can add support where they make sense for your training load, diet and individual needs.
We are active ourselves. That is why our focus is not on recommending as much as possible, but on what may genuinely fit your sport, everyday routine and goals.
Before looking at individual products, we start with what supports training in the long term.
Before individual products become relevant, a simple order helps. Priorities shift with sport, duration and intensity.
Adequate total energy and, for longer or intense efforts, suitable carbohydrate sources form the foundation.
Fluid and electrolyte planning becomes more important with duration, heat and sweat loss.
Protein supplies amino acids. Essential amino acids must come from the diet and are building blocks for the body's own proteins.
Vitamins and minerals are part of normal nutrition. The quality of the overall diet comes first.
Training does not work in isolation. Sleep, load management, energy, protein and fluid intake belong together.
Before discussing creatine, electrolytes or other sport-specific supplements, we separate everyday nutritional support from targeted sports products.
In our sports framework, we use these two products as our personal daily FitLine routine. That is our approach – not a claim that every athlete needs both products.
What we consume through food and supplements must first be digested and absorbed. That is why we consider digestion and gut routine part of the overall picture – also for active people.
This does not mean that a gut product automatically improves athletic performance.
For sports products, ingredients are only part of the picture. For competitive athletes, product safety, manufacturing standards and transparent testing are particularly relevant.
PM-International currently states that all FitLine food supplements are listed on the Cologne List®. The list publishes tested products and helps minimize doping risk.
View Cologne List →FitLine describes its products as Made in Germany and manufactured according to GMP. GMP stands for defined manufacturing and quality-control standards.
According to current FitLine information, product quality is regularly and independently tested by ELAB Analytik GmbH.
NTC® is FitLine's described Nutrient Transport Concept. We present it as a manufacturer technology – not as independent proof of improved athletic performance.
Not every supplement makes sense for every athlete. Sport, training volume, diet and goals all matter.
| Area | Einordnung | FitLine reference | When can it be relevant? |
|---|---|---|---|
| Kreatin | well studied | Creatine+ | Especially relevant for repeated short, high-intensity efforts. |
| Energy & focus | Caffeine well studied · product requires context | Activize Guarana extract, caffeine, vitamin C, niacin, B vitamins, biotin and more. | Potentially useful before selected sessions. Several vitamins contribute to normal energy-yielding metabolism; evidence for caffeine should not be transferred wholesale to the full product. Consider tolerance and sleep. |
| Beta-Alanin | well studied · context-dependent | no direct equivalent | Relevant for certain high-intensity efforts. |
| Carbohydrates + electrolytes | well studied · context-dependent | Fitness-Drink | Most relevant for longer or more intense sessions. Fitness-Drink combines fluid with carbohydrates and minerals; it is not automatically needed for every workout. |
| Protein / essential amino acids (EAA) | Protein well studied · EAA context-dependent | Whey · ProShape Aminos | Food first; add more only when needed. |
| Arginine & citrulline (amino acids) | mixed / context-dependent | Munogen | Of interest in sports science, but the evidence needs context. |
| Magnesium / minerals | individual intake | Restorate | Can fit around physically demanding days, after training or in the evening as mineral support; not a blanket recovery or performance claim. |
| Omega-3 fatty acids EPA & DHA | individual intake | FitLine Omega 3 | Targeted intake of the omega-3 fatty acids EPA and DHA; not an immediate performance product. |
| Micronutrients | individual intake | PowerCocktail | Daily nutritional support rather than a direct performance boost. |
| Cardiovascular complex | individual | Heart Duo | Consider separately; it should not simply be treated as an omega-3 product. |
| Joints / cartilage & bones | nutritional support · not a treatment | Gelenk-Fit | A nutritional support topic for heavily loaded joints and musculoskeletal structures; persistent symptoms should be professionally assessed. |
| Collagen / connective tissue | supportive | Beauty | A collagen and vitamin C topic related to connective tissue; not a treatment for tendon or ligament problems. |
| Topical care / cooling | topical care product | Active Gel | For topical care and cooling of stressed skin areas when desired; not a medical recovery claim. |
To avoid oversimplifying the product links, we show the key ingredients and how to place them in context. An authorised nutrient claim is not automatically evidence that the whole product produces the same effect.
Contains, among other things: Guarana extract, caffeine, vitamin C, niacin, pantothenic acid and vitamins B1, B2, B6 and B12, folic acid and biotin; plus botanical ingredients such as turmeric and ginger extracts.
How we view it: Several of the B vitamins, as well as vitamin C and niacin, contribute to normal energy-yielding metabolism. Caffeine itself is well studied in sport, but its effects and tolerance depend on dose, timing, habituation and individual sensitivity. Guarana is included as a botanical extract; on the current German ingredient list, guarana extract and caffeine are listed separately.
Important: No blanket performance claim is made for the complete product; caffeine later in the day may interfere with sleep.
Contains: Kreatin sowie Magnesium.
How we view it: Creatine is one of the best-studied sports supplements. The authorised performance claim relates to successive bursts of short-term, high-intensity exercise and requires a daily intake of 3 g of creatine. Magnesium contributes, among other things, to normal muscle function and normal energy-yielding metabolism.
Particularly relevant for strength training, sprinting and repeated high-intensity efforts in team sports.
Main focus: Fluid intake combined with carbohydrates and minerals/electrolytes.
How we view it: For longer or more intense sessions, combining fluids, carbohydrates and electrolytes can become more relevant. For short, easy sessions, water and a normal diet are often enough.
It is not automatically necessary for every workout. Always check the current label for the exact composition.
Contains: Whey protein concentrate. The available German label lists approximately 16.6 g of protein per prepared serving.
How we view it: Protein contributes to the growth and maintenance of muscle mass. Whey is therefore most useful when the required amount of protein is not conveniently met through normal foods.
A protein shake is not necessary when the diet already provides enough protein.
Basic principle: Proteins are made of amino acids. After digestion, the body uses amino acids to build its own proteins, among other things. Essential amino acids cannot be produced by the body and must come from the diet.
Contains: Leucine, valine, isoleucine, lysine, phenylalanine, threonine, methionine and tryptophan.
How we view it: Overall protein intake remains decisive. Leucine has a particular role in regulating muscle protein synthesis. An amino-acid product does not replace adequate nutrition and is not automatically needed when intake is already sufficient.
According to the available German label, it contains, among other things: L-arginine, L-citrulline, grape and apple extracts, as well as B vitamins/folic acid.
How we view it: Arginine and citrulline are studied in sports settings, but the evidence is less clear-cut than for creatine or caffeine. Performance effects should therefore not be inferred for Munogen as a whole simply from individual amino acids.
Existing user data on Activize + Munogen are limited and should not be treated as robust evidence for Munogen on its own.
Contains, among other things: Calcium, magnesium, selenium, copper, manganese, chromium and vitamin D.
How we view it: Magnesium contributes to normal muscle function and normal functioning of the nervous system. Calcium, magnesium and manganese contribute to the maintenance of normal bones.
This is mineral support – not a promise of faster recovery or better sleep.
Contains: DHA omega-3 from high-quality microalgae.
How we view it: DHA contributes to the maintenance of normal brain function at a daily intake of 250 mg. In sport, omega-3 is better viewed as a long-term nutritional topic than an acute or pre-workout product.
According to the current German product description, it contains: plant-based DHA omega-3 and thiamine; the manufacturer also lists coenzyme Q10 as an ingredient.
How we view it: DHA contributes to the maintenance of normal brain function at 250 mg per day. Thiamine contributes to normal heart function. That is why we treat Heart Duo separately from a pure omega-3 product.
Main focus: Vitamins and other micronutrients for daily nutritional support.
How we view it: The current Optimal Set includes, among other things, vitamin B6 with its contribution to normal energy-yielding metabolism; vitamins B6, B12 and C contribute to normal psychological function. That places PowerCocktail in the area of daily nutritional support rather than as a direct sports-performance product.
Relevant substantiated ingredient: Vitamin C.
How we view it: Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones. This is an authorised nutrition-related claim, not a promise to treat joint complaints, injuries or osteoarthritis.
According to the available product label, it contains, among other things: Vitamin C, niacin, vitamin E, vitamin B2, biotin, zinc and copper.
How we view it: For this sports page, the vitamin C link is the most relevant because vitamin C contributes to normal collagen formation. Beauty is still not a product for treating tendon, ligament or joint injuries.
How we view it: Active Gel is a topical care product and is deliberately not assessed on this page as if it were a food supplement.
We describe it only as an optional topical care/cooling product and do not infer medical recovery, pain relief or healing effects from it.
According to the German label, it contains: protein-enriched whey powder, 19.8% inulin and lactic acid cultures, plus niacin. Prepared with milk, the product also provides protein and calcium.
How we view it: Calcium contributes to the normal function of digestive enzymes. We position the yoghurt as a possible nutrition/gut-routine option, not as a sports-performance or recovery product.
We distinguish between well-studied areas, context-dependent approaches and supply topics. Where the evidence is mixed, we say so.
One of the best-studied supplements in sport. Particularly relevant for repeated short, high-intensity efforts.
Alongside caffeine, Activize Oxyplus contains guarana extract, vitamin C, niacin, pantothenic acid and several B vitamins. These vitamins have authorised functions, for example in normal energy-yielding metabolism. Caffeine itself is well studied in sport, but we do not transfer caffeine research wholesale to the complete product.
Beta-alanine is an amino acid. The body uses it together with histidine to form carnosine in muscle. Carnosine plays a buffering role during certain high-intensity efforts. FitLine currently has no product containing beta-alanine or carnosine as a direct ingredient.
Protein is fundamental for building and maintaining muscle mass. EAA means essential amino acids – amino acids the body cannot make itself and must obtain from the diet. ProShape Aminos provides eight essential amino acids; beta-alanine and carnosine are not among them. Extra intake is not automatically necessary when protein intake is already sufficient.
Arginine and citrulline are amino acids studied in sports science, including in relation to nitric oxide (NO). Existing Munogen data should always be presented with the study design and its limitations.
EPA and DHA are two omega-3 fatty acids. The focus here is primarily on intake, not an immediate performance increase in the next workout.
The same product bundle for everyone makes little sense. Open the section that is closest to your training.
Needs change considerably from an easy 5K to a half marathon. For short sessions, training and normal food remain the priority. As duration increases, fluids, carbohydrates and recovery become more relevant.
Cycling, triathlon, swimming and other longer endurance efforts place different demands on the body than short sessions. Energy, fluids and electrolytes become more important.
Sprints, jumps, changes of direction and repeated high-intensity actions occur within a longer overall workload. Rather than using a fixed product bundle, the useful question is: what is actually missing around your specific demands?
Strength development, muscle gain, adequate energy and protein intake, and recovery take centre stage. Creatine is one of the best-studied supplements in this context.
Not as a fixed product bundle, but according to need, training load and recovery.
