What is collagen hydrolysate?

Collagen hydrolysate is collagen protein that has undergone hydrolysis, a chemical process involving water and enzymes. Under the influence of hydrolysis, the collagen molecule is broken down into smaller collagen peptides. As a result, they are better absorbed in the intestines than natural collagen or gelatine.

Imagine that your intestines are a sieve through which you are trying to sift something. Gravel is unlikely to pass through the small mesh. However, if you pour in sand, there is no problem.

If you pour in sand, there is no problem.

You could say that collagen hydrolysis is crushing it out of the gravel to the size of grains of sand. Cyk! and the absorbability is greater.

Collagen hydrolysate is commonly used in anti-aging supplements because it improves hair, skin, nails and reduces wrinkles and provides joint flexibility because it has the properties of collagen in your body.

Collagen hydrolysate - broken down into prime particles

What is collagen hydrolysate made of?

Collagen hydrolysate is obtained from fish, ox, pigs and sometimes poultry and eggs. Most of this protein is found in skins, cartilage, tendons and bones and, in the case of fish, also in scales and bonesand.

As you can see, collagen is an animal protein, meaning all products called 'vegan collagen' are actually substitutes containing plant-based amino acids. And while these substances may also support the proper functioning of the body to some extent and have positive effects on skin, hair and nails, they will not give the full effects associated with zoonotic collagen supplementation.

Natural collagen is not found in the plant world. However, vegans and vegetarians can ensure that ingredients that stimulate its synthesis, such as vitamin C, are introduced into the diet. It can be found in peppers, broccoli, spinach, strawberries, blackcurrant or kiwi. It is also important to remember to get enough plant protein, such as pulses, groats, rice or nuts.

Alexandra Cudna Clinical nutritionist

The effects of collagen hydrolysate supplementation are not matched by food products. Jelly in fractures? That's definitely not enough.

Why?

It is all about so-called bioavailability, i.e. how quickly, easily and pleasantly your body will be able to absorb these protein amino acids. To put it simply: the collagen molecules contained in food are large enough that mostand of them won't get through the sieve that is the walls of your intestines.

The body's bioavailability is a question of bioavailability.

What is the difference between hydrolysate and regular collagen?

Hydrolysate differs from regular collagen primarily in terms of particle size. In hydrolysate, the long protein chain of collagen is broken down into smaller fragments called peptides. In normal collagen, this chain remains intact.

Collagen hydrolysate has a lower molecular weight and dissolves better in water. As a result, it has greater bioavailability and efficacy compared to regular collagen.

What is better: collagen hydrolysate or collagen?

For most people, collagen hydrolysate is the better choice because it is more easily absorbed into the body. Collagen hydrolysate has undergone a process of hydrolysis, which is the breaking down of long protein chains into shorter molecules - known as peptides.

This makes collagen hydrolysate more bioavailable (better absorbed), which enhances the effects of its use. Regular collagen requires larger amounts of digestive enzymes to be broken down into smaller fragments, making it less effective compared to hydrolysate.

There is one exception, however:

Native collagen is recommended for people with inflammatory joint disease because, according to research, it is used as a desensitising particle for the body not to attack its own cells.

Collagen hydrolysate versus hydrate

Collagen hydrate is collagen treated with water or aqueous solutions, or hydration. It is also often referred to as hydrated collagen or collagen gel. Hydration affects the elasticity of collagen fibres and.

Collagen hydrate, is collagen to which water molecules have attached themselves, but unlike hydrolysate, in hydrate the protein does not break down into smaller molecules.

Ilona Krzak Master of Pharmacy

Collagen hydrate is most commonly used in research, where it is used as a skin substituteand.

Collagen hydrolysate, on the other hand, is used in dietary supplementation studies because its smaller fragments are more easily absorbed by the body than whole collagen protein.

Collagen hydrolysate vs lyophilisate

Liophilisate is obtained by freezing and drying collagen to remove water from it. This makes freeze-dried collagen more concentrated, meaning it can be added to a product in a higher doseand.

However, for a dietary supplement to be effective, it is not only the dose that matters, but also the bioavailability of the main ingredient. Hydrolysate, by breaking down collagen into small peptides, digests much more easily and penetrates the body better.

Collagen hydrolysate versus gelatine

Gelatin is collagen protein dissolved in hot water. This simple process also has a complicated name: denaturation. Gelatin, although it can be a source of collagen in the diet, is not as effective as collagen hydrolysate.

By the way - don't be afraid that something is denatured. You regularly denature the things you eat: you boil eggs - denature. You fry chops - denaturation. It's just that you change the structure of the protein and that's it.

The collagen molecules in gelatine are large enough that they may not be digested effectively. Collagen hydrolysate has smaller molecules than gelatine and is also easier to digest.

Collagen hydrolysate has smaller molecules than gelatine and is also easier to digest.

What types of collagen can you find in hydrolysate?

The most common types of collagen you'll find in hydrolysate supplements are types I, II and III.

Type I is the collagen that is most abundant in our bodies (around 90%). It is present in the skin, joints and bones.

Type II is the best friend of athletes and people struggling with joint pain. It fills cartilage tissue, bones and aids joint synovial production.

Type III is found in the walls of blood vessels and the intestines. Its intake may have a positive effect on the cardiovascular system.

Collagen hydrolysate - fish or zoonotic?

Research makes it clear: the molecules of fish collagen (a.k.a. marine collagen) most closely resemble those of humans, and this ensures that they are best absorbed into our bodiesand. Supplementation with marine collagen may therefore yield better results than taking products isolated from slaughtered animals.

Bovine, porcine or fish? I definitely recommend the latter. Why? The absorption and assimilation of fish collagen is highest due to its low molecular weight. Importantly, fish collagen is much easier to dissolve in water, which simply makes it more convenient to use. In addition, we reduce the risk of contracting diseases of animal origin, such as so-called mad cow disease.

Alexandra Cudna Clinical nutritionist

Fish collagen is also an option for pescatarians, i.e. vegetarians who allow the consumption of fish in their diet.

Interesting facts

Marine collagen is also known as fish collagen, however it does not have to be derived from fish at all. Research suggests that it can be effectively isolated from, for example... sea cucumber (unfortunately for vegans, it's still not a vegetable)and.

Collagen hydrolysate - effects

Collagen protein hydrolysate is the best absorbed form of this substance. This ensures you get the most reliable effects.

Results from scientific studies show that after just 8 weeks of collagen hydrolysate supplementation, changes can be observed in the appearance of the skin in the form of increased elasticity and hydration levels.

Alexandra Cudna Clinical nutritionist

As she adds, regular supplementation also reduces joint soreness, both that associated with intense exercise and degenerative changes. Well, an increase in muscle mass and faster recovery from injuries is also observed.

She adds.

See what you can expect with regular use of collagen hydrolysate.

Smooths hair, skin, nails

Collagen is called the protein of youth because it is responsible for the condition of our skin. As its basic building block (70-80%), it takes care of its firmness and elasticity, as well as promoting wound healing. Collagen fills in the tissues and thus results in a shallowing of wrinkles and improved skin firmnessand.

Collagen supplementation will benefit the state of the skin all over the body. It will become more resilient and tighter. Thus, collagen hydrolysate may also prove helpful in the fight against cellulite or "fresh" stretch marks and.

Collagen hydrolysate will also work on the scalp, which is key to improving hair health. A healthy, moisturised scalp is like the soil in which the roots (but not the flowers but the hair) grow. It is what gives them the nutrients they need to grow properly.

Our hair and nails are mainly keratin, which is made up of amino acids. One of these is glycine, also present in collagenand. Youth protein hydrolysate can therefore benefit everyone with dreams of lush, shiny hair and damage-resistant nails .

Strengthens joints, bones and muscles

Collagen is found in joint cartilage and is important for the production of joint fluid. If one were to compare our joints to hinges, the synovium would be grease. When the body stops producing it in sufficient quantities, the cartilage starts rubbing against each other. This often causes pain and discomfort when moving.

Supplementation with collagen hydrolysate will support the production of joint lubricant and thus increase movement comfort. It may also prevent osteoarthritisand.

Research suggests that taking collagen peptides together with calcium and vitamin D has a positive effect on bone density, which is particularly important for women during and after menopauseand.

Supplementation with hydrolysed collagen also indirectly supports building muscle mass in people who participate in sports , and in older age - together with appropriate exercise - can prevent the loss of muscle mass .

Using collagen hydrolysate can therefore help keep the entire musculoskeletal system healthy, and keep you fit and functioning without pain for years to come.

Collagen hydrolysate - for whom?

Collagen is one of the best researched and safest substances you can supplementand. We particularly recommend it for people who want to:

maintain a youthful appearance,
smooth wrinkles and reduce their appearance,
improve skin density and firmness,
have healthy joints,
minimise the risk of osteoporosis,
improve the condition of nails,
thicken hair,

Collagen is also recommended for physically active people - it reduces joint soreness, strengthens bones, and speeds up recovery from injury. Studies show that collagen supplementation can also be beneficial for older people, as it increases muscle and bone mass and reduces joint pain.

Alexandra Cudna Clinical nutritionist

The hydrolysed form of this formula will work well for people who want fast results. However, that is not all:

People with digestive disorders may find it difficult to digest collagen properly and therefore the protein will not be absorbed. Similarly for people with intestinal and gastritis, in whom absorption will also be impaired. In such cases, hydrolysate is definitely preferable.

Ilona Krzak Master of Pharmacy

Collagen hydrolysate - contraindications

Although collagen hydrolysate is a safe compound, there are times when those taking it may experience mild gastrointestinal discomfortand.

Another counterindication to taking collagen are allergies, which may relate to the collagen itself (e.g. a fish allergy in the case of fish collagen supplementation), as well as to other ingredients present in the product being taken.

Note

Always check the composition of the product before starting supplementation! If you are taking other medications or are pregnant, consult your doctor before taking a supplement - always discuss the specific product as collagen supplements vary in composition and active ingredients.

Collagen hydrolysate - what to look for when choosing one?

Origin

You already know that marine-derived collagen in its structure is better adapted to your body, so it is more efficiently absorbed. When choosing the ideal formula for yourself, it is worth taking this into account.

Dose

The higher the dose of collagen, the better, however, as with everything, common sense should be exercised here too.

The higher the dose, the better.

For daily, long-term supplementation, formulations containing 5,000 mg of hydrolysate are best suited. For those who want to quickly replenish a deficiency, a dose of 10 000 mg may be better.

Additional ingredients

It is a good idea to choose formulations that contain collagen supplement ingredients in addition to the hydrolysate. The most popular are hyaluronic acid and vitamin C, which supports the body's natural collagen synthesis.

If you want to supplement with collagen hydrolysate for the sake of your skin, hair and nails, look for supplements like biotin, field horsetail, or vitamins A and E.

And if your goal is to improve function, chondroitin sulphate or vitamin K may be helpful.

FAQ

Does collagen hydrolysate work?

Yes, this is confirmed by numerous scientific studies. Collagen hydrolysate is an effective dietary supplement that benefits the condition of skin, hair, nails and joints, as well as the entire musculoskeletal system. Supplementation with collagen hydrolysate can help improve skin elasticity, reduce the appearance of wrinkles, strengthen hair and nails, and reduce joint pain and increase joint mobility. However, it is important to remember that the effectiveness of the hydrolysate depends on its quality, as well as on correct dosage and regular use.

How much collagen hydrolysate to take per day?

It is usually recommended to take approximately 2.5 to 15 g of collagen hydrolysate per day to benefit the condition of skin, hair, nails and joints. However, tailor this dosage to your individual needs. Also pay attention to the manufacturer's guidelines for the product in question and do not exceed the maximum daily serving. If you are in doubt about the dosage and how to use the hydrolysate, consult your doctor or pharmacist.

Which collagen hydrolysate is best?

The best bioavailable (i.e. bioavailable) type of collagen is fish collagen hydrolysate. This is because its structure most closely resembles that found in the human body. This collagen is extracted from the scales, skins and bones of marine fish.

Is drinking collagen safe?

Supplements of drinking collagen are safe if you choose them from trusted brands and do not exceed the recommended daily dose. It is best if you read the label before use to ensure that the product does not contain ingredients to which you are allergic. Pregnant and breastfeeding women or those taking other medications should consult a doctor for supplementation.

As with any product, collagen hydrolysate may also cause adverse reactions in some people, most commonly from the digestive system.

What time to take collagen?

As a general rule, the time at which you take collagen does not matter. Experts recommend that you do not take it immediately before bedtime, as it can give you a feeling of fullness in the stomach. Also check what the manufacturer itself says about how and when to take your product: for example, some supplements are most effective when taken with a meal.

What is hydrolysis?

Hydrolysis is the chemical process of breaking down the molecules of a substance into smaller ones using water and other enzymes.

Hydrolysis of collagen involves breaking down collagen protein into smaller and more digestible fragments - collagen peptides.

Does collagen hydrolysate affect the liver?

Collagen hydrolysate is considered safe at the doses recommended on the packaging and should not have a negative effect on the liver. Collagen hydrolysate is usually a product derived from natural protein sources. However, if you suffer from a liver ailment, it is worth consulting your doctor before starting supplementation.
