Does collagen peptides help with weight loss?

Yes, collagen peptides can help in weight loss. The body quickly takes collagen peptides, making them an effective means of giving the protein your body requires while keeping you full for a long time. Moreover, collagen peptides enhance metabolism and decrease fat storage. Research has shown that consuming 15-20g of collagen peptides daily for two months can significantly lower body fat percentage.

In addition to its potential for weight loss, collagen peptides may help improve joint health and reduce inflammation. Incorporating collagen into your diet can benefit overall health and wellness and aid in weight loss goals.

How much collagen do I need daily to lose weight?

The amount of collagen you need daily to lose weight varies on your needs. Generally speaking, 15 grams daily is a good starting point for most people. It can help you build muscle bulk, lose fat, and improve power.

In addition to consuming collagen supplements daily, other lifestyle changes can help you reach your weight loss goals such as eating a balanced diet and exercising regularly. Incorporating these habits into your routine can help you achieve the desired results safely and sustainably.

Best time to take collagen for weight loss

The best time to take collagen for weight loss is 15 minutes before your next meal. When taken before a meal, collagen helps to reduce cravings and encourage a feeling of fullness. This can help you make better daily food choices and stick with your weight loss plan. Collagen can also increase metabolism and boost energy levels, further aiding in weight loss.

How Collagen Peptides Can Help with Weight Loss?

Role in Metabolism

Collagen peptides contain a unique amino acid composition, rich in glycine, proline, and hydroxyproline. These amino acids play essential roles in various metabolic processes, such as energy production and protein synthesis, which may indirectly impact weight loss.

Muscle Maintenance and Growth

Collagen is a significant component of muscle tissue, and supplementing with collagen peptides may help maintain and grow lean muscle mass. An increase in lean muscle mass leads to a higher resting metabolic rate, which means your body burns more calories at rest, thus aiding weight loss.

Appetite Regulation

Collagen peptides may also help regulate appetite by promoting feelings of fullness and satiety, reducing overall calorie intake and supporting weight loss efforts.

Scientific Evidence Supporting Collagen Peptides for Weight Loss

Studies on Collagen and Weight Loss

While the data is limited, several studies show collagen peptides may help reduce weight. According to a 2019 research published in the Journal of Medicinal Food, overweight persons who took a collagen peptide supplement for 12 weeks lost 1.5% body fat and gained 2.3 pounds of muscle. However, it is crucial to emphasize that this was tiny research with non-statistically significant findings.

Another research published in the British Journal of Nutrition in 2018 discovered that taking a collagen peptide supplement for 8 weeks resulted in a slight decrease in body fat compared to those who took a placebo. The impact was, however, minor, and it is crucial to highlight that these studies had drawbacks, such as small sample numbers and short research durations.

Limitations and Considerations

While some studies display promising results, researchers need to conduct more studies to reach definitive conclusions about the effectiveness of collagen peptides in weight loss. Additionally, it’s essential to consider factors such as dosage, duration, and individual differences when evaluating the potential benefits of collagen peptides.

How to Incorporate Collagen Peptides into Your Diet?

Collagen Supplements

One of the easiest ways to incorporate collagen peptides into your diet is through supplements. You can find collagen supplements in various forms, such as powders, capsules, and gummies. Collagen powders are especially popular as they can be easily mixed into beverages like coffee, tea, or smoothies.

Food Sources of Collagen

While supplements are a convenient option, you can also obtain collagen peptides from natural food sources. Some collagen-rich foods include:

  • Bone broth
  • Fish, especially the skin
  • Chicken, particularly the skin and cartilage
  • Pork, especially the skin and connective tissue
  • Gelatin, derived from animal collagen

Additional Tips for Weight Loss Success

Balanced Diet and Exercise

While collagen peptides may support weight loss, combining them with a balanced diet and regular exercise is crucial. A diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats is essential for overall health and weight management. Additionally, cardiovascular and resistance exercises will further enhance weight loss efforts.

Lifestyle Changes

Apart from diet and exercise, making sustainable lifestyle changes is critical for long-term weight loss success. These changes may include the following:

  • Getting enough sleep
  • Managing stress levels
  • Staying hydrated
  • Reducing alcohol consumption
  • Quitting smoking

Potential Side Effects and Risks

Collagen peptides are generally considered safe, but some potential side effects may include:

  • Allergic reactions, particularly if you have a known allergy to the source of the collagen (e.g., fish, shellfish, or eggs)
  • Digestive issues, such as bloating, gas, or diarrhea
  • A feeling of heaviness or fullness in the stomach

Always consult a healthcare professional before starting any new supplement regimen, especially if you have any underlying health conditions or are pregnant or breastfeeding.


Collagen peptides might contribute to weight loss by promoting metabolism, muscle growth and maintenance, and regulating appetite. Although some studies reveal promising outcomes, researchers need to conduct more studies to validate the effectiveness of collagen peptides in facilitating weight loss. Including collagen peptides, a balanced diet, regular exercise, and healthy lifestyle changes, may aid in your weight loss journey.


Can I rely solely on collagen peptides for weight loss?

No, you should use collagen peptides to complement a balanced diet, regular exercise, and healthy lifestyle changes.

Are there any side effects to taking collagen peptides?

Possible side effects might involve allergic reactions, digestive issues, and a sensation of heaviness in the stomach. If you experience any adverse effects, consult your healthcare professional.

What is the recommended dosage of collagen peptides for weight loss?

The ideal dosage can vary based on individual factors; however, most studies recommend a daily intake of 10-15 grams of collagen peptides.

Can I get enough collagen peptides from my diet alone?

While it is possible to obtain collagen peptides from natural food sources, supplements can be a convenient way to ensure adequate intake, especially if you have dietary restrictions or preferences.

How long does it take to see results from taking collagen peptides for weight loss?

Results may vary, but some studies suggest that noticeable changes may occur within 8-12 weeks of consistent collagen peptide supplementation alongside a balanced diet, regular exercise, and healthy lifestyle changes. However, individual results may vary based on age, genetics, and overall health.
