Read on as we explore more about collagen peptides, from what they are to their advantages and ways to boost your intake!
Collagen Peptides: What is it and How it Differs from Collagen
Collagen is the most abundant protein in the body. Its function is to make connective tissue
At the same time,
This is how collagen supplements can come in handy. Some of these supplements are available as pills, powders or drinks that need to be consumed. This kind of supplement is known as collagen peptides or hydrolysed collagen.
Collagen peptides are made from the broken-down version of collagen, so they are more easily
Health Benefits of Collagen Peptides
Collagen peptides possess the same benefits as collagen. They can enhance skin condition, increase muscle mass, prevent bone loss and reduce joint pain.

Improves brain health
The human brain is the centre of the nervous system. Several scientists have researched the correlation of collagen intake with brain function. One study from Italy reports that collagen-producing cells and collagen proteins (type VI and XIX in particular) are found in the brain’s neural parenchyma – the functional tissue in charge of cognition and the rest of the body.
There is evidence that the consumption of collagen peptides can
By increasing your collagen intake, either with foods or supplements, you have made an effort to maintain your brain function and possibly delay cognitive decline due to ageing.
Improves gut health
Dealing with bloating and constipation? Don’t ignore these conditions. A clinical trial published in the Journal of Medical Internet Research shows some results that prove collagen can reduce bloating and improve mild digestive problems.
In addition, collagen peptides can prevent further breakdown of the intestinal barrier, which helps alleviate symptoms of leaky gut and inflammatory bowel disease (IBS). However, it’s best to take collagen supplements as instructed.
Consuming a high dosage of collagen peptides is not recommended. A 2020 study by researchers in China shows that they could alter the gut microbiota and short-chain fatty acid metabolism. So, always take your supplements in moderation.
Improves cardiovascular health
Like the brain, a healthy heart consists of approximately 80% type I collagen and 10% type III collagen. A new review published in the British Journal of Nutrition in 2022 determines that collagen peptides can significantly decrease the biomarkers related to cardiovascular diseases.
Other studies also support this finding. One in particular reports that collagen peptides may help prevent plaque build-up in the arteries and potentially reduce the LDL to HDL ratio. Additionally, they can decrease the body fat percentage in obese or overweight patients. These are notable risk factors for cardiovascular diseases, including stroke, heart attack, and hypertension.
Natural Sources of Collagen
As a result, applying said serums or creams may be an option for those who want to make the skin feels smoother. If you want all the benefits mentioned above, an oral collagen supplement is better.
Collagen can also be found in several ingredients or foods:
- Bovine (cows, oxen, goats, sheep, bison, buffalo), especially the tough cuts of meat. They include brisket, round, chuck, shank and other parts of an animal’s body that have to work the hardest to support its weight.
- Offal from the stomach, tripe, tail and bone marrow of animals.
- Bones and skin of salt and freshwater fishes.
- Bone broth. As collagen is found in the bones of animals, which we don’t normally eat, making broth out of bones is one way to increase your collagen intake.
- Gelatine. Made from boiling animal bones, cartilage and skin, gelatine is part of the paleo diet.
- Poultry, eggs, dairy, legumes and soy contain amino acids.
- Porcine (pork).
Some staple ingredients in Traditional Chinese Medicine (TCM) may also help to boost collagen intake. They are bird’s nest as well as sea cucumber (hai shen, 海参), snow fungus (yin’er, 银耳), fish maw (yu du, 鱼肚), peach gum (tao jiao, 桃胶), and goji berry (gou qi, 枸杞), all of which are rich in amino
It bears remembrance that collagen peptides may not work instantly. Your body constantly loses collagen, so collagen peptides
