Benefits and risks for hair, skin and more
Liquid collagen is a supplement that contains collagen protein suspended in a liquid, such as purified water. Some research suggests that collagen supplements may be beneficial for the health of the hair, skin, nails, and joints.
However, most research does not focus specifically on liquid collagen. There are also certain risks to be aware of when considering a collagen supplement.
This article explains what collagen and liquid collagen are, the types of liquid collagen available, the benefits and risks associated with collagen supplementation, and dietary sources of collagen.
Collagen is a type of protein that structures tissues such as skin, bones, ligaments, tendons, organs, teeth, muscles, and blood vessels. Collagen represents

Some people take collagen as a dietary supplement. Drinking liquid collagen is one way to do this. These products contain collagen proteins which are hydrolyzed or broken down into smaller blocks. These smaller blocks, or peptides, are easier for the body to absorb.
Many liquid collagen supplements contain purified water as a liquid component, although some contain juices or other liquids. Companies sell liquid collagen in pre-made drinks, often in the form of individual shots, vials, or smoothies.
The collagen in liquid collagen products can come from different sources. It helps to know the differences before you think about buying a supplement.
Beef tissues are the
- chicken, duck or rabbit skin
- marine fish or invertebrates (such as jellyfish or sponges)
In the cosmetics industry, marine collagen is one of the most popular types because it causes less inflammation than animal sources and is less likely to contain contaminants, according to a
There is a lack of research that specifically looks at liquid collagen. However, according to a
- slow down the formation of fine lines and wrinkles
- improve the skin’s ability to absorb and retain moisture
- reduce pigmentation or darkening of the skin
- improve the elasticity and firmness of the skin
- promote rejuvenation of skin cells
- improve skin texture
- improve the density and thickness of the skin
- improve healing time
- reduce cellulite and skin rippling
- improve joint and bone health
- improve nail strength and growth
In the same trial, participants who consumed the liquid collagen supplement experienced an approximately 43% reduction in joint pain and a 39% improvement in joint mobility. However, the supplement also contained other ingredients, such as amino acids, vitamins, and minerals, making it unclear whether collagen was responsible for the changes.
In one small study 2017, 25 women who took 2.5 grams (g) of bioactive collagen-specific peptides once daily for 24 weeks experienced:
- 12% increase in nail growth
- 42% reduction in nail breakage
- improvement in the fragility of the nails 4 weeks after treatment
- improvement in the appearance of nails 4 weeks after treatment
In addition, researchers from a Study 2020 concluded that taking 2.5g of bioactive collagen peptides daily for 16 weeks increased hair cell growth by 31% and significantly increased hair thickness. However, these tests involved specific peptides, not the products people can find in stores.
Overall, early research into the benefits of collagen supplements for skin, hair, and nails is promising, but more research on the benefits of specific liquid collagen products is needed to prove that they are. just as effective.
Many people tolerate collagen supplements well. However, it is best to consult a doctor each time you start a new supplement to verify that it is safe and to use the supplement according to the doctor’s instructions or the product label.
Some people may have an allergic reaction to collagen supplements. For example, if someone has a shellfish allergy and consumes marine collagen, they
If a person develops swelling of the face, mouth, or throat after taking collagen, call 911 or the nearest emergency service number immediately.
If a person experiences new symptoms after taking a collagen supplement, they should stop taking it and see a doctor.
In addition to allergic reactions, there are other potential risks associated with taking liquid collagen.
The United States Food and Drug Administration (FDA) regulates dietary supplements as food products rather than drugs. This means that supplement companies are not required to prove the safety or effectiveness of collagen supplements.
At best, this can mean that some products may not work. However, there have also been instances where companies have sold collagen powder from unsafe sources and contaminated with toxic substances such as cadmium or mercury.
In other cases, companies have mixed prescription drugs into beauty supplements in order to achieve the desired effect. It can be very dangerous.
Some supplements may list their ingredients inaccurately, which can mean that people who avoid certain animal products for ethical, dietary, or religious reasons might end up taking something they object to.
Additionally, liquid collagen supplements sometimes contain vitamins, minerals, or herbs. These can be safe in moderate amounts, but some can interact with a person’s medications and underlying conditions. Some can also cause toxicity in high doses, such as iron.
People can avoid these risks by purchasing only collagen supplements that have been tested by third parties to ensure that they are pure and come from safe collagen sources. A doctor can tell someone if the ingredients of a particular supplement are right for them.
The best sources of collagen come from animal products that people generally don’t eat, such as animal skin, bones, cartilage, and scales. However, a few foods contain collagen at lower levels. These include:
- beef, chicken and pork
- dairy products
- bone broths or bone products
Some marine plants and animals also contain collagen,
- sea urchins
- muscles and oysters
Vitamin C also helps the body to synthesize collagen. People can get more vitamin C by eating foods such as:
Liquid collagen is a type of collagen supplement that can improve the health of the skin, nails, and hair. It consists of collagen peptides suspended in a liquid.
It is important to consider the type and source of collagen before choosing a product, and to choose brands that test all of their products with a third party to ensure quality and purity. Always discuss any new supplement with a doctor.
