While it is well-known that protein is important for building and repairing muscles, many people also wonder whether eating lots of protein can help make their skin healthier. In this blog post, we will explore the relationship between protein intake and skin health.

What is protein?

Protein is an essential nutrient that is responsible for a wide range of important functions in the body. One of its primary roles is to help build and repair tissues, including muscles, bones, and skin. 

It is also involved in the production of enzymes, hormones, and other molecules that are necessary for proper bodily function.

Proteins are made up of a chain of smaller building blocks called amino acids. 

There are 20 different types of amino acids, and the body needs all of them in order to function properly. Some of these amino acids can be produced by the body, while others must be obtained through the diet.

The amount of protein that a person needs can vary depending on a variety of factors, including their age, sex, and level of physical activity. However, most healthy adults require between 0.8 and 1.2 grams of protein per kilogram of body weight each day. 

It’s important to note that consuming more protein than this may not provide any additional benefits and can even have negative effects on health.

How does protein benefit the skin?

Protein plays a very important role in maintaining healthy skin. The skin is the body’s largest organ, and it is made up of several layers, each with a specific function. 

The outermost layer of the skin, called the epidermis, is responsible for protecting the body from external factors such as the sun, pollution, and other environmental stressors.

Protein is essential for the production of collagen, which is a protein that gives the skin its elasticity and strength. Collagen is found in the dermis, the second layer of the skin, and it helps to keep the skin firm and smooth. 

As we age, the production of collagen decreases, which can lead to wrinkles, sagging skin, and other signs of aging.

Protein also plays a role in the production of elastin, another protein found in the dermis that gives the skin its elasticity. Elastin allows the skin to stretch and return to its original shape, which is important for maintaining healthy skin.

Finally, protein is necessary for the production of keratin, a protein that makes up hair and nails. Keratin helps to keep hair and nails strong and healthy, which can contribute to overall skin health.

Does eating more protein lead to better skin health?

While protein is undoubtedly essential for maintaining healthy skin, it is not necessarily true that eating more protein will automatically lead to better skin health. 

A balanced diet that includes adequate protein, along with other essential nutrients such as vitamins, minerals, and healthy fats, is crucial for optimal skin health.

It is worth noting that excessive protein intake can actually have a negative effect on the skin. 

When the body consumes more protein than it needs, the excess protein is broken down and excreted from the body, which can put stress on the kidneys and liver. This can lead to dehydration and inflammation, which can affect the skin’s appearance.

Consuming too much protein can potentially result in the body producing more insulin-like growth factor 1 (IGF-1), a hormone that can stimulate cell growth and division. Although IGF-1 is important for growth and development, excessive amounts of it have been associated with a heightened risk of specific cancers, such as skin cancer. 

Thus, it is important to consume protein in moderation and obtain it from a diverse range of sources to ensure the body receives all the necessary amino acids.

What are some protein sources that can help maintain healthy skin?

Some of the best sources include:

  1. Fish: Fish, particularly fatty fish like salmon and mackerel, are rich in omega-3 fatty acids and high-quality protein. Omega-3s can help reduce inflammation, which can lead to improved skin health.
  2. Eggs: Eggs are a great source of protein and contain biotin, which is important for healthy skin, hair, and nails.
  3. Nuts and seeds: Nuts and seeds, such as almonds, sunflower seeds, and chia seeds, are rich in protein, healthy fats, and antioxidants that can help protect the skin from damage.
  4. Legumes: Legumes, such as beans, lentils, and chickpeas, are a good source of plant-based protein and contain other skin-healthy nutrients like zinc and folate.
  5. Dairy products: Dairy products, such as milk, cheese, and yogurt, are excellent sources of protein and also contain calcium, which is important for healthy bones and teeth.

Incorporating these protein sources into your diet can help ensure that you’re getting all the nutrients your skin needs to look and feel its best.


While protein is an essential nutrient that the body needs to function properly, consuming too much of it can have some drawbacks.

One potential issue with consuming excessive protein is that it can put a strain on the kidneys. 

The kidneys are responsible for filtering waste products out of the blood, and a high-protein diet can result in an increased workload for these organs. This can lead to kidney damage and even kidney failure in some cases, particularly in people with pre-existing kidney disease.

Another potential issue with high-protein diets is that they can be high in saturated fat, which can increase the risk of heart disease.

Red and processed meats, which are often high in protein, are also associated with an increased risk of certain cancers, such as colorectal cancer.

It’s important to note that not all sources of protein are created equal. 

For example, plant-based protein sources are generally healthier than animal-based sources because they are lower in saturated fat and cholesterol. However, some plant-based sources of protein, such as soy products, may contain phytoestrogens, which can have hormonal effects in the body.

In addition, some high-protein diets may not provide all the essential nutrients that the body needs to function properly. For example, if you’re consuming a lot of protein from meat, you may not be getting enough fiber, which is important for digestive health.

To avoid these drawbacks, it’s important to consume protein in moderation and to obtain it from a variety of sources. 

balanced diet that includes plenty of fruits, vegetables, whole grains, and lean protein sources can provide all the nutrients your body needs to look and feel its best.


In conclusion, protein is an important nutrient that the body needs to function properly, and it plays a crucial role in maintaining healthy skin. However, consuming too much protein can have some drawbacks, such as putting a strain on the kidneys, increasing the risk of heart disease and certain cancers, and potentially leading to nutritional deficiencies.

To ensure that you’re getting all the nutrients your body needs to look and feel its best, it’s important to consume protein in moderation and to obtain it from a variety of sources. Some of the best sources of protein for healthy skin include fish, eggs, nuts and seeds, legumes, and dairy products.

By incorporating these protein sources into your diet, along with plenty of fruits, vegetables, and whole grains, you can ensure that you’re getting all the nutrients your body needs to thrive. 

Remember to always consult with a healthcare professional or a registered dietitian to determine the best diet plan for your unique needs and goals.

To help minimize our carbon footprint, for every product order a tree will be planted thanks to our amazing planters at One Tree Planted. It’s estimated that a mature tree nullifies around 20lbs of CO2 a year.

We’re doing our best to reuse, reduce and recycle. Wishing to inspire a circular economy we have partnered up, to create a customized recycling program. Collect three empty plastic packages to receive your Anbiome Recycling Envelope and follow the instructions on how to take part in our recycling mission. 

Your good deed shall be rewarded. For every three products recycled you receive one product gift!


Today’s trends in skincare require the use of synthetic active ingredients which interact with the skin. Our approach is to distinguish natural alternatives, which mimic the skins native repair mechanism and are more efficient and ecologically sound.

Translating solutions from nature into industrial settings is hardly an easy task, but it’s one we enjoy undertaking.

We have screened 500+ different wild probiotic strains from the nature, to find the most powerful ones.

Special fermentation process was developed to harvest powerful molecules (HA, LTA, SMase, LA and 40 peptides).

Result is the composition of native signal components and molecules that keep the skin balanced, healthy and protected.
