Collagen is the most abundant protein in the body, providing structure to hair, skin, nails, tendons, ligaments, bones, muscles and fascia. Collagen peptides are very small pieces of protein from animal collagen, and they are used for various purposes, including dry skin, ageing skin, osteoarthritis, osteoporosis, brittle nails, and muscle strength. There is some evidence that collagen peptides may improve hand-grip strength, relieve muscle and joint pain, and enhance muscle recovery. However, there is no strong scientific evidence to support many of these uses, and more research is needed to understand the specific effects of collagen peptides on muscle cramps and other conditions.

What You'll Learn
Collagen peptide supplementation may improve muscle recovery
Collagen is the most abundant protein in the body and is made up of amino acids. It provides structure to hair, skin, nails, tendons, ligaments, bones, muscles and fascia. As we age, collagen deteriorates, leading to muscle and joint stiffness, loss of skin elasticity, and decreased bone density.
Collagen peptide supplementation is a popular method to replenish old, damaged collagen. Collagen peptides are very small pieces of protein from animal collagen, made by breaking down whole collagen proteins into smaller pieces. When taken orally, collagen peptides build up in the skin and cartilage, improving skin hydration and elasticity, and may help with certain joint conditions.
Several studies have indicated that collagen peptide ingestion relieves muscle and joint pain, and may improve muscle recovery. Lopez et al. (2015) found that collagen peptides attenuated creatine kinase (CK) activity following muscle-damaging exercise, indicating enhanced muscle recovery. Clifford et al. (2019) found that collagen peptides derived from chicken sternal cartilage improved recovery, reduced delayed onset of muscle soreness, and lowered plasma biomarkers for muscle damage and inflammation.
The benefits of collagen peptide supplementation are closely linked to their molecular weight, with peptides in the range of 2000 to 3500 daltons showing superior absorption and effectiveness compared to those with a molecular weight of around 5000 daltons. This is due to the improved bioavailability and absorption of collagen peptides with lower molecular weights, which are generally absorbed more efficiently.
Therefore, collagen peptide supplementation may improve muscle recovery, particularly when combined with resistance training.

Collagen peptides may reduce muscle soreness
Collagen is the most abundant protein in the human body. It is made up of amino acids and provides structure to hair, skin, nails, tendons, ligaments, bones, muscles, and fascia. As we age, collagen deteriorates, leading to muscle and joint stiffness, loss of skin elasticity, and decreased bone density.
Collagen peptides are small pieces of protein derived from animal collagen. They are produced by breaking down whole collagen proteins. Collagen peptides are often used to improve skin and joint conditions, and there is some evidence to suggest they may also help with muscle soreness.
Several studies have indicated that collagen peptide ingestion can relieve muscle and joint pain associated with diseases such as osteoarthritis. Some studies have also reported reductions in self-reported joint pain in healthy individuals. Additionally, collagen peptides have been shown to attenuate creatine kinase activity following muscle-damaging exercise, suggesting enhanced muscle recovery.
One particular study examined the effects of consuming collagen peptides before and after strenuous exercise. The study found no significant difference in muscle soreness between the collagen peptide group and the placebo group. However, a large effect size was evident at 48 hours post-exercise, indicating lower soreness in the collagen peptide group.
Overall, while more research is needed, collagen peptides may help reduce muscle soreness and improve recovery, especially when combined with resistance training.

Collagen peptides may improve hand-grip strength
Collagen is the most abundant protein in the body, providing structure to hair, skin, nails, tendons, ligaments, bones, muscles, and fascia. It is made up of amino acids and allows us to move with fluidity and control. Collagen peptides are very small pieces of protein from animal collagen. They are made by breaking down whole collagen proteins into smaller pieces.
Collagen peptides are used for various purposes, including dry skin, aging skin, and osteoarthritis. They are also used for osteoporosis, brittle nails, and muscle strength. However, there is limited scientific evidence to support most of these uses.
Several studies have indicated that collagen peptide ingestion can relieve muscle and joint pain, particularly in individuals with osteoarthritis. It has also been shown to reduce self-reported joint pain in physically active but otherwise healthy people. Additionally, collagen peptides have been found to enhance muscle recovery following strenuous exercise.
While collagen peptides do not seem to improve leg muscle strength, they may improve hand-grip strength. Jendricke and colleagues (2019) found an increase in hand-grip strength with collagen peptide supplementation, suggesting a medium effect size. Similarly, a study in recreationally active men found an increase in hand-grip strength with collagen peptide supplementation.

Collagen peptides may not improve leg muscle strength
Collagen is the most abundant protein in the human body, providing structure to hair, skin, nails, tendons, ligaments, bones, muscles, and fascia. It is made up of amino acids and allows us to move with fluidity and control. Collagen peptides are small pieces of protein derived from animal collagen, and they have been shown to improve skin hydration and elasticity, particularly in older people.
Collagen supplements are often used to improve muscle strength, but there is limited scientific evidence to support this. While collagen peptide supplementation has been shown to improve body composition and strength when paired with resistance training, there is no evidence that it improves leg muscle strength on its own. In fact, one source states that "taking collagen peptides by mouth does not seem to improve leg muscle strength".
However, collagen peptides may improve hand-grip strength, and several studies have indicated that collagen peptide ingestion relieves muscle and joint pain in diseases such as osteoarthritis. Collagen peptide supplementation has also been shown to promote recovery, decrease pain, and improve strength and body composition when combined with resistance training.
While collagen peptides may not directly improve leg muscle strength, they could still be beneficial for overall muscle health and recovery, particularly when used in conjunction with other therapies or treatments. More research is needed to fully understand the effects of collagen peptides on muscle strength and performance.

Collagen peptides may help with osteoarthritis and rheumatoid arthritis
Collagen is the most abundant protein in the human body, providing structure to hair, skin, nails, tendons, ligaments, bones, muscles and fascia. It is made up of amino acids and allows us to move with fluidity and control. As we age, collagen deteriorates, leading to many dysfunctions, from muscle and joint stiffness to a loss of elasticity in the skin, and even a decrease in bone density.
Collagen supplements have been investigated as a treatment for a host of problems, including ageing skin, wound healing, osteoarthritis (OA), rheumatoid arthritis (RA), bone health (osteoporosis) and high cholesterol. Most trial results have been at least modestly positive, although some studies lack quality.
Collagen is anti-inflammatory, so scientists reason that it may help RA and other inflammatory forms of the disease. However, there is no clear evidence of this yet, mainly due to a lack of well-conducted trials.
Collagen is widely used to induce arthritis in animal models, and the potentially immunogenic properties of collagen have been continuously reported. However, several in vitro, in vivo, and clinical studies have claimed the anti-arthritic effects of collagen and peptides. For example, a study published in Science Advances by Katsumata et al. revealed that collagen bound to an anti-TNF-α antibody, suppressing arthritis development.
Collagen is increasingly used for its treatment in patients with osteoarthritis. Low-molecular-weight collagen peptide (LMWCP) has shown a significant decrease in knee pain in patients with OA.
