Tendons, ligaments, cartilage, and fascia also have to transfer and repeatedly absorb loads. This Collagen for Athletes Guide explains when collagen may be useful, what dosage suits your goals, and how to recognize a high-quality product.
Why collagen has a distinct role in sports
Collagen is the most abundant structural protein in the human body. It is a key component of skin, bones, cartilage, tendons, ligaments, and connective tissue. For athletes, this function is particularly relevant: while conventional protein powder primarily supports daily protein intake and, in turn, muscle growth, collagen provides amino acids that are commonly found in collagen-rich tissues.
These include glycine, proline, and hydroxyproline in particular. This does not mean that collagen replaces whey, vegan protein, or a protein-rich diet. Its amino acid profile is less complete for muscle protein synthesis because it contains comparatively few essential amino acids and very little leucine. So if you want to build or maintain muscle mass, you should continue to ensure an adequate intake of high-quality protein sources.
Collagen can be a useful addition to this foundation when the focus is on the resilience of the musculoskeletal system. This applies not only to competitive athletes. Strength athletes with high training frequency, runners, CrossFit athletes, and people returning to structured training after a longer break also regularly put stress on their tendons and joints.

Collagen for athletes: when supplementation makes sense
The greatest benefit does not come from a single serving, but from combining regular training, sensible load management, and consistent supplementation. Collagen is not a painkiller or a shortcut to proper technique or sufficient recovery time. If symptoms persist or worsen, seek medical advice before starting any supplement protocol.
In practice, there are three typical uses. First: high, recurring loads from strength training, sprinting, running, or team sports. Second: a training phase focused on stability, movement quality, and tolerance to training loads. Third: a long-term focus on skin and connective tissue, where physical activity and general health goals come together.
Having realistic expectations is essential. Collagen provides building blocks, but it does not replace therapy or change your capacity to handle loads overnight. Tendons and other connective tissues respond to training stimuli more slowly than muscles do. So if you use collagen, think in terms of weeks and months rather than days.
Tendons and ligaments under heavy loads
Tendons transfer muscle force to the bone. They are put under particular strain during explosive movements, high eccentric loads, and high training volumes. Examples include deep squats, heavy pressing variations, jump training, and long runs. Adequate energy and protein intake remain the foundation. Collagen may be a useful addition because it provides amino acids suited to structural tissue.
That also means you cannot make up for a lack of adaptation time by suddenly doubling your training volume. Progressive training, technique, sleep, and enough calories form the foundation.
Joints, cartilage, and training comfort
Joint discomfort can have various causes. Inactivity, sudden peaks in load, limited mobility, unfamiliar exercises, or previous injuries may all play a role. Collagen hydrolysate is often used to supplement daily intake of collagen-specific peptides. Many users see it primarily as a way to improve training comfort during regular activity.
Whether you notice an effect, and how strong it is, depends on your starting point. If you train without discomfort, you are more likely to be pursuing a preventive, long-term strategy. If pain keeps returning, an individualized approach makes more sense than pinning your hopes on a single supplement.
Skin and an active lifestyle
Collagen is not just about sports. Skin also contains large amounts of collagen. Specific collagen peptides such as Verisol® are studied particularly in relation to skin elasticity. For active people, this may be an additional reason to include collagen in their daily routine. Choosing the right product is still important: not every collagen product has the same goal or contains the same amount of peptides.
The right dosage: let your goal guide you
There is no one-size-fits-all collagen dose that works equally well for every training goal. For conventional collagen hydrolysates, practical amounts often range from about 5 to 15 grams per day. Smaller amounts may be suitable for ongoing supplementation in everyday life. Higher amounts are more commonly used when the focus is specifically on heavily loaded connective tissue.
Consistency matters more than taking the maximum amount. A serving only on particularly hard training days does little justice to the long-term nature of connective tissue. Choose a dose you can reliably take every day and that is clearly stated on the label.
For collagen peptides targeting the skin, the amount often differs depending on the branded ingredient used and is specifically tested. The number of grams alone is not the only factor that matters. The peptide profile, ingredient quality, and the dose at which the ingredient was studied are also relevant.
Timing: before training or anytime during the day?
Timing can be useful, but it is less important than your total daily intake. If you want to take collagen specifically around a workout to support tendons and connective tissue, you can take a serving about 30 to 60 minutes before exercise. This makes sense before a workout that actually loads the tissue you want to target - for example, before running drills, calf raises, jumps, or strength training with controlled repetitions.
Vitamin C plays a role in the body’s own collagen production. A balanced diet with fruits and vegetables meets your needs in many cases. There is therefore no need to automatically take additional high doses. If you take collagen before training, a meal or snack containing a source of vitamin C during the day can be a practical addition.
On rest days, the timing matters less. Many people take collagen with breakfast, in coffee, in a shake, or between meals. Follow the manufacturer’s instructions for hot drinks. High-quality collagen peptides generally dissolve well and are easy to fit into your daily routine.
Collagen hydrolysate, gelatin, or a branded ingredient?
Collagen hydrolysate consists of enzymatically broken-down collagen proteins, known as peptides. Their smaller size makes them easy to dissolve and measure. Gelatin comes from a similar source, but gels more readily and is less versatile for everyday use. Collagen hydrolysate is usually the more practical choice for shakes and drinks.
It is worth taking a closer look when choosing an ingredient. A clearly identified branded ingredient does not automatically guarantee better results for every goal, but it offers transparency about the source, specifications, and available data on the peptide profile used. Verisol®, for example, is an established branded ingredient with a specific focus on skin. Depending on the product, other collagen peptides and dosages may be suitable for structures stressed by sports.
The source matters, too. Collagen is typically obtained from cattle, pigs, fish, or poultry. Bovine collagen is widely available and the standard choice for many applications. Fish collagen is often associated with type I collagen and may be of interest to people who are mindful of specific sources. The point is not that one is universally “better,” but that the ingredient source, quality, and personal preferences should all align.
How to recognize a good collagen product
A high-quality product does not need a long ingredient list to make a good impression. With collagen, transparency and a sensible dosage matter more than marketing terms. First, check how many grams of collagen peptides you actually get per serving. A large tub does not tell you much if the daily serving is small.
Also look for full disclosure of the collagen source, a traceable ingredient, and as few unnecessary additives as possible. Flavored powders can be convenient, but depending on the formula, they may contain sweeteners, flavors, or other ingredients. Unflavored collagen offers maximum flexibility, while flavored varieties can make it easier to stick to a daily routine. The better choice is the one you use consistently and tolerate well.
For discerning buyers, manufacturing quality is also relevant. German manufacturing, batch-specific quality checks, and transparent labeling all build confidence. MST Nutrition focuses on exactly these points: clear formulas, tested ingredients, and dosages that are easy to understand.
Safety and tolerance
Collagen is generally well tolerated by most healthy adults. However, individual intolerances can occur, for example due to the animal source or other ingredients. Fish collagen is of course not an option if you have a known fish allergy. Pregnant or breastfeeding people, people with medical conditions, and anyone who regularly takes medication should consult a doctor before supplementing.
Collagen complements a performance-focused diet, but does not replace it. Continue to include enough protein from complete sources, consume enough calories, and use carbohydrates strategically for intense workouts. Creatine, protein, and collagen serve different purposes - which is exactly why they can work well together in a thoughtful supplement plan.
If you see collagen not as a quick fix, but as a daily part of a long-term approach to resilient training, you are making a more realistic choice. Give your routine time, train progressively, and choose a product whose ingredient source and dosage you can understand without compromise.
