What can affect the quality of tendons?

Various factors can affect the quality of tendons, including age, repeated injuries, an unbalanced diet that is too high in fats and sugars and lacks sufficient plant-based foods, or inadequate hydration. The level and type of physical activity also play a role, and a sedentary lifestyle can, over time, reduce the mechanical resistance of tendons to stretching. Collagen helps to strengthen tendons, promote their recovery and reduce the risk of injury. Collagen supplementation can help to compensate for the age-related decline in natural collagen production and support tendon health.

What are tendons, tendinitis, and tendinopathy?

Let’s try to make sense of this terminology and understand what lies behind each of these terms. Tendons: These are fibrous, elastic connective tissues that connect muscles to bones. Their main function is to transmit the force generated by muscle contraction to the bones, thereby enabling the movement of joints and the body. Tendons are composed mainly of collagen. It is this that gives them their strength and elasticity. Tendinitis: This is an inflammation of a tendon. It is generally the result of repetitive movements that consistently strain the same part of the body. The areas most frequently affected by tendinitis are the shoulders, wrists, knees, elbows and ankles. This inflammation causes pain, sometimes accompanied by redness and swelling, and affects the mobility of our joints. A distinction must be made between tendinitis, an inflammatory condition, and tendinosis, which is characterised by degeneration of the tendon. Tendinopathy: Tendinopathy is a generic term referring to any painful condition affecting a tendon. Unlike tendinitis, which refers to inflammation of the tendon, tendinopathy encompasses any condition affecting the tendon in the broadest sense. This may involve tendinitis, but may also include an injury or pain that impairs joint mobility. Tendinopathy can be caused by repetitive movements, as is the case with tendinitis. Age and wear and tear can also account for these changes. Collagen plays a vital role in maintaining our tendons and protecting us from tendinopathies. The treatments offered may vary depending on the type of tendon condition. In addition to rest, muscle rehabilitation or other medical interventions may be recommended if necessary.

Are the dietary sources of type I and type II collagen the same?

Collagen comes mainly from animal sources, regardless of whether it is type I or type II. Dietary sources of type I collagen include collagen-rich animal tissues such as skin, bones, tendons and ligaments. Type II collagen, on the other hand, is found mainly in animal cartilage, particularly from chicken and cattle. Type I collagen is more commonly consumed through the diet than type II collagen. However, the collagen content of foods varies, and obtaining a specific dose through food alone may be difficult. Collagen supplements can provide a more concentrated source, particularly of type II collagen.

How can you increase the body’s absorption of collagen?

To increase collagen absorption, it is recommended that you Consume , as it promotes collagen production. is available as a dietary supplement, or in food, particularly in citrus fruits, peppers, strawberries and kiwis. Cook food at a low temperature to preserve the collagen. Combine your intake of collagen with foods rich in amino acids, such as pulses and nuts, which promote its synthesis This will enable you to reap the full benefits for your body.

What Is the Connection Between Collagen and Tendons?

By Christine Barris

Published on: Thursday, April 18, 2024, Updated on: Thursday, October 29, 2026

Tendons connect our muscles to our bones. They guard our mobility, strength, and agility. When they become painful, less flexible, or damaged, our ability to move is impaired. Collagen isn’t just the protein behind our skin’s youthfulness and beauty; it also plays a role in the flexibility of our tendons and joints.

In this article, we’ll take a closer look at the benefits of collagen, its role in our tendons, and how to incorporate it into our diet to maintain flexibility and prevent injuries.

What Is Collagen?

Collagen is a protein made up of amino acids. It occurs naturally in the human body. In fact, it is the most abundant protein in the body, accounting for about a third of the body’s total protein content.

It is found in the skin, bones, cartilage, joint tissues, muscles, tendons, and ligaments. It is also present in many other parts of our body, such as blood vessels, the cornea, and teeth. The term collagen comes from the Greek word ‘kólla’, which means ‘glue’. It can indeed be thought of as the glue that holds all these elements together.

However, our body’s natural production of it tends to decline with age, which may lead us to seek natural ways to consume it or stimulate its production.

The Benefits of Collagen

Collagen offers a host of benefits for our bodies:

Healthy Skin, Nails, and Hair: Collagen helps keep the skin looking youthful by promoting better hydration and minimising the signs of ageing. It is often recommended in combination with hyaluronic acid, whose benefits it effectively complements. It also promotes wound healing and strengthens nails and hair
Joint Mobility: It maintains and improves joint flexibility by playing a role in the structure of cartilage and the elasticity of tendons
Bone Density and Strength: It promotes better bone mineralisation, which helps to prevent the risk of fractures. In this respect, a collagen supplement may be beneficial for older people
Muscle Performance and Regeneration: It has a beneficial effect on muscle function and recovery. This is essential for athletes, whose muscle regeneration capabilities can decline over time

Why Is Collagen Beneficial for Tendons?

Tendons are made up largely of collagen fibres, which give them their strength and help them withstand mechanical stress. Collagen supplementation is being studied for its potential role in supporting tendon health and recovery following injury. However, its effects on tendon elasticity, regeneration and injury prevention are not yet fully established.

Here are some of the ways collagen may affect tendon health:

Supports Tendon Structure: Collagen is the main structural protein in tendons. Adequate collagen intake helps provide the body with the building blocks needed to maintain connective tissues
May Support Elasticity and Flexibility: Collagen contributes to the tendons’ ability to withstand stretching and mechanical stress. Research is exploring whether supplementation can help support these properties and tendon function
May Support Tendon Repair: Collagen provides amino acids involved in the formation of connective tissue. Supplementation is being studied for its potential to support tendon recovery following injury or inflammation, such as tendinitis

The proper functioning of tendons depends partly on the quality and organisation of their collagen fibres. Maintaining healthy connective tissue is therefore important for tendon function, although collagen supplementation cannot currently be considered a proven way to prevent injuries or accelerate tendon regeneration.

Which Collagen Should You Take for Your Tendons?

We have seen that there are several types of collagen, each of which plays a different role in the body.

Type I Collagen: Particularly Important for Tendons and Muscles

Type I collagen is found in large quantities in tendons, where it is a major structural component. It is also present in other connective tissues, including the skin, bones and ligaments. Type II collagen, on the other hand, is found mainly in articular cartilage.

Collagen Treatment

What Is the Recommended Dosage?

The collagen booster is very convenient and easy to take. Simply dissolve 2 teaspoons of powder in a glass of water or fruit juice. You can also add it to a smoothie, milkshake, or vegetable juice for an even greater vitamin and antioxidant boost.

The recommended daily dose for optimal effectiveness is 2.5 to 10g, depending on your needs.

How Long Does the Course of Treatment Last?

We recommend taking the supplement for 2 to 3 months to fully benefit from the Vegan Collagen Booster’s effects on the skin.

Precautions for Use and Contraindications

A marine collagen supplement may be unsuitable in the following cases:

Seafood allergies
Kidney failure
People under 25 years of age
Pregnancy and breastfeeding, unless advised by a healthcare professional

Anyone undergoing medical treatment should seek advice from a healthcare professional before taking any dietary supplements.

Dietary supplements should be used as part of a healthy lifestyle and a varied, balanced diet. To preserve product quality, store them away from heat and light and keep them out of reach of young children.

Alternatively, you can consider our Vegan Collagen Booster, which supports the synthesis of type I collagen. It combines a synergistic blend of amino acids designed to replicate the amino acid profile of type I collagen with natural extracts of ginseng and Centella asiatica, as well as Vitamin C, to support the body’s natural collagen synthesis.

Expert Advice

Lifestyle and diet play a role in maintaining our muscles, tendons, and joint mobility. It is recommended to follow a varied diet, rich in fruit and vegetables. Drink plenty of low-mineral-content water, which helps flush out waste products. Take regular exercise. Ensure good-quality sleep and manage stress through relaxing activities. This is because an excess of toxins caused by an unhealthy diet can affect the condition of our tendons and contribute to inflammation.
