“The study suggests that SCD can help reduce excess body fat and it can be considered a potential alternative treatment for obesity itself and associated disorders. If it is combined with exercise and dietary intervention, the effect of SCD can be greater.”

If you’re considering taking collagen supplements to improve your health, you may be wondering if they can also help you lose weight. Unfortunately, there’s no clear answer to this question.

Some people believe that collagen can help promote weight loss by increasing muscle mass and decreasing fat storage.

Additionally, some experts believe that collagen may actually cause weight gain because it can lead to increased food cravings and overeating.

If you’re trying to lose weight, it’s important to speak with your doctor before taking any supplements, including collagen. They can help you create a plan that’s right for you and your health goals.

Collagen supplements have become a popular way to improve skin health and the overall health of aging bodies, but what about weight gain?

Let’s take a closer look at what collagen does for your body, some of the benefits, and side effects you may experience while taking the supplement.

What does collagen do for your body?

Collagen is the most abundant protein in your body, accounting for about one-third of its total protein content. It’s found in your skin, bones, tendons, muscles, and other connective tissues. 

As you age, your body produces less collagen, which can lead to wrinkles and joint pain. Collagen supplements are thought to help reverse these effects by increasing the levels of collagen in your body.

Collagen is a type of protein that’s made up of amino acids. Some types of collagen are used to make dietary supplements, which are available in powder, liquid, and capsule forms. Collagen supplements are usually made from cow or fish sources.

Collagen supplements are thought to have a variety of health benefits, including improving skin health, reducing joint pain, and helping with weight loss

Helps Build Muscle

One of the main reasons people take collagen supplements is to help build muscle mass. Collagen is a major component of muscle tissue, so it’s thought that increasing your collagen intake can help build muscle.

Building muscle is important for a number of reasons. First, having more muscle mass can help you burn more calories, even at rest.

Second, muscle is essential for strength and mobility as you age. And finally, having strong muscles can help protect you from injuries.

Strengthens Bones

Another reason people take collagen supplements is to strengthen bones. Collagen is a major component of bone tissue, so it’s thought that increasing your collagen intake can help strengthen bones.

This is especially important for older adults, who are at greater risk for osteoporosis, a condition characterized by weak and fragile bones.

Taking collagen supplements may just be the answer to some of your bone health issues

Improves Joint Health

Joints are surrounded by a layer of tissue called cartilage. This tissue is made up of collagen, water, and other molecules. Over time, the collagen in cartilage can break down, leading to joint pain.

Some people take collagen supplements to help improve joint health. The thinking is that increasing your collagen intake can help rebuild cartilage and reduce joint pain.

Who should take collagen supplements?

Most people can safely take collagen supplements. However, there are a few groups of people who may want to avoid them.

Pregnant women and nursing mothers: Collagen supplements haven’t been studied in pregnant women, so it’s unclear if they’re safe. Nursing mothers should also avoid taking collagen supplements.

People with allergies: Collagen is derived from animal sources, so people with allergies to chicken, beef, or fish may be allergic to collagen supplements. 

People with autoimmune diseases: Collagen is a type of protein, and some people with autoimmune diseases may have an adverse reaction to protein supplements.

If you have an autoimmune disease, it’s best to speak with your doctor before taking collagen supplements.

What are the side effects of collagen supplements?

Collagen supplements are generally considered safe. However, like all supplements, they can have side effects. The most common side effects include:

Digestive issues: Collagen supplements can cause upset stomach, heartburn, and diarrhea. If you experience any of these side effects, it’s best to stop taking the supplement.

Allergic reactions: As mentioned above, people with allergies to chicken, beef, or fish may be allergic to collagen supplements.

If you experience any symptoms of an allergic reaction, such as hives or difficulty breathing, stop taking the supplement and seek medical attention.

While the effects of taking collagen supplements are usually positive, there are a few potential side effects to be aware of. If you experience any adverse reactions, it’s best to stop taking the supplement and speak with your doctor.

Weight gain: how it happens

It’s no secret that many people struggle with their weight. You may have tried numerous diets and exercise programs, only to find that the pounds just keep creeping back on. So, how does weight gain actually happen?

There are a few different ways.

First, when you eat more calories than your body needs, those extra calories are stored as fat.

Second, your body may become less efficient at burning calories as you age. And finally, certain medications and health conditions can lead to weight gain.

The good news is that there are things you can do to prevent or minimize weight gain. Eating a healthy diet and getting regular exercise are two key factors.

And if you’re concerned about medications or health conditions affecting your weight, talk to your doctor. With a little effort, you can keep those unwanted pounds from coming back.

How does collagen affect your weight?

There are a few different ways that collagen can affect your weight. First, collagen is a type of protein, and protein is essential for building muscle mass.

If you’re not getting enough protein in your diet, your body will break down muscle tissue to get the protein it needs. This can lead to weight gain. 

Second, collagen is also essential for healthy skin. If you’re not getting enough collagen, your skin may become dry and wrinkled. This can lead to a decrease in self-esteem, which can lead to overeating and weight gain. 

And finally, collagen supplements can also help reduce joint pain. If you’re in pain, you may be less likely to exercise, which can lead to weight gain.

So, does collagen cause weight gain? While it’s possible that collagen supplements may contribute to weight gain in some people, it’s more likely that they’ll help you maintain a healthy weight. 

Many people have reported great success with their weight loss journey while taking collagen supplements. Here are a few ways that collagen works against weight gain:

Collagen Makes You Feel Fuller

One of the main reasons people take collagen supplements is to help with weight loss. The thinking is that collagen can help you feel fuller after eating, so you’ll eat less and lose weight.

Some studies have found that collagen does indeed help with weight loss. One study showed that people who took a collagen supplement felt fuller after eating than those who didn’t take a supplement.

When your body signals to you that you feel full, you’re less likely to overeat. This can help you lose weight or prevent weight gain.

Collagen Reduces Body Fat

Did you know that collagen could help you reduce body fat? That’s right–this protein, which is found in abundance in our skin, tendons, and bones, can also help improve our metabolic rate and promote the breakdown of stored fat. 

Choosing collagen for weight loss

If you’re choosing to boost your natural collagen supply and aim for a weight loss goal at the same time, collagen peptides may help you avoid some of the side effects associated with other weight loss supplements, such as stimulants.

And since collagen is a protein, it can also help you build muscle mass, which can in turn help you burn more calories.

If you’re looking for a way to lose weight, collagen may be worth considering. This natural supplement has few side effects and may help you lose weight by making you feel fuller and reducing body fat.

The Bottom Line

Collagen supplements have a wide range of potential health benefits, including aiding in weight loss.

Collagen can also help you feel fuller after eating, which may lead to reduced calorie intake and weight loss.

Additionally, collagen may help reduce body fat and increase muscle mass, both of which can help with weight loss. If you’re struggling to lose weight, collagen may be worth trying as a natural and safe supplement.

  1. Should you eat your collagen with breakfast or later in the day? Can I take it with diatomaceous earth?

    I am on my third bag of collagen but have not yet noticed a difference? When should I start to notice a difference?

    Can I test for iodine by putting your iodine on my forearm to see if I need it? If it disappears I need it, which I think I do.

    Thank you,


    • Hi Linda Sheet, Thank you for your interest in our Clean Sourced Collagens. This can be taken any time of day with food or on an empty stomach. It can be mixed with any liquid drink hot or cold. Regarding diatomaceous earth unfortunately, we are unfamiliar with the product/supplement and unable to comment on mixing it with this. Please check with your trusted healthcare provider for information regarding that product. Most people see and feel results within 1-3 months of consistent usage. There are a few different ways to test for iodine deficiency. However, we recommend getting your blood tested via your doctor or a trusted lab. I hope you find this information helpful. Have a happy and healthy day!
