All About Collagen – The Complete Guide 2025

Collagen has become one of the most talked about substances in health and beauty in recent years. You may have heard about it from friends, seen it in pharmacies, or come across articles about its miraculous effects. But what exactly is collagen and why is everyone talking about it?

Why read this article? In this complete guide, you’ll learn everything you need to know about collagen – from basic information to practical advice on how to use it properly for your health and beauty. You’ll also learn why not all collagen products work the same and what to look out for when choosing one.

What is collagen and why is it so important for our body?

Collagen is the most abundant protein in the human body and makes up to 30% of all proteins in our body. Think of it as the “glue” that holds our bodies together. It is found in the skin, bones, muscles, tendons, ligaments, blood vessels, and almost all tissues.

Collagen is responsible for the strength and elasticity of the skin, the health of joints and cartilage, the strength of bones and teeth, the functionality of blood vessels and the heart, as well as tissue regeneration. Without collagen, our bodies would simply “fall to pieces”.

Here comes the problem – although our body naturally produces collagen, from the age of 25 its production starts to slow down as we get older. Every year we lose about 1-2% of collagen, which shows the first signs of aging. Visible signs of collagen deficiency include the first wrinkles and loss of skin elasticity, painful and stiff joints, slower wound healing, weaker hair and brittle nails, as well as fatigue and lower energy.

What are the main types of collagen and which is the best?

Scientists have so far identified more than 28 types of collagen, but the three main types are the most important for our health. Type I collagen is found in the skin, bones, tendons and teeth – responsible for skin elasticity and bone strength. Beef and marine collagen are the best sources.

Type II collagen is found in cartilage and joints, where it provides joint mobility and cartilage protection. The best source of this type is chicken collagen. Type II collagen is particularly important for people with joint problems and arthritis.

Type III collagen is found in muscle tissue, blood vessels and organs, where it promotes muscle strength and blood vessel health. Why is a combination of types more effective? Modern research shows that the combination of different types of collagen works synergistically – that is, the effect of the whole is greater than the sum of the parts. This is why the highest quality collagen products, such as HEXXXA Pro-Age Collagencombine several types of collagen with other active ingredients.

Why is hydrolyzed collagen key to effectiveness?

Not all collagen is equally effective. The key is that it must be hydrolyzed – that is, broken down into small collagen peptides that our bodies can easily absorb. Hydrolyzed collagen has a high bioavailability of up to 95%, rapid absorption into the blood, better tissue utilization, and causes no digestive problems.

Pure collagen powder is often the most effective form because it dissolves and absorbs quickly. Tablets may contain fillers that reduce effectiveness, while liquid collagen has a shorter shelf life and is more expensive to produce.

HEXXXA Pro-Age Collagen contains exclusively hydrolysed collagen peptides of the highest quality. Each serving contains 7000 mg of hydrolysed bovine collagen peptides and 2700 mg of hydrolysed fish collagen peptides. In addition, the product also contains 3000 mg of glycine, which promotes recovery and sleep quality. This combination provides complete support for all tissues.

How do we know a quality collagen product?

There are a few key factors to look out for when choosing collagen products. A quality nutritional supplement should contain hydrolyzed peptides instead of whole molecules, a combination of collagen types – at least Type I and Type II, a quality source such as free-range beef, purity free of artificial additives, colors and preservatives, as well as certifications confirming proven quality and safety.

You should avoid cheap collagens of unknown origin, products with a lot of artificial additives, non-hydrolysed forms and unclearly labelled ingredients. HEXXXA Pro-Age Collagen meets all of these criteria, plus it contains a synergistic combination of six natural active ingredients.

In addition to the two types of collagen, the product contains acerola with 1000 mg of natural vitamin C, which is essential for the formation of collagen. It also contains resveratrol (145 mg) known for its antioxidant properties and astaxanthin (8 mg), which is considered one of the most powerful natural antioxidants.

Can we get enough collagen from natural sources?

Natural collagen is found in bone broths, gelatin, fish skin, beef skin and chicken feet. However, the problem is that collagen from food is difficult to absorb, we would need to consume large quantities, it is not practical to eat bone broth on a daily basis, and heat treatment partially breaks down the collagen.

Therefore, collagen supplements are a more practical choice. They provide a concentrated form of collagen in easily absorbed peptides with precise dosing and ease of use. The bioactive collagen in supplements has the added benefit of often being combined with substances that promote its absorption and effectiveness.

HEXXXA Pro-Age Collagen is an ideal solution because it combines the effectiveness of concentrated collagen with natural substances that support its function in the body.

How exactly does collagen work in our body?

When you take quality hydrolyzed collagen, a gradual regeneration process happens. During the first 30-60 minutes, the collagen peptides are absorbed in the small intestines and enter the bloodstream. Within 1-2 hours, the blood carries the peptides to the tissues where they are concentrated where they are most needed.

After 2-4 hours, the peptides signal the cells to produce collagen and the regeneration process is triggered. Over the following days to weeks, new collagen is formed in the tissues and the condition of the skin and joints gradually improves. This process is supported by the presence of vitamin C from acerola in HEXXXA Pro-Age Collagenwhich is essential for the formation of collagen in the body.

In addition, the glycine contained in the product supports sleep quality and regeneration, while astaxanthin protects collagen structures from free radical damage. Resveratrol contributes to overall blood vessel health and promotes healthy aging.

When can we expect the first results?

Realistic expectations are important when taking collagen. During the first 1-2 weeks, you can expect better sleep and energy, as well as improved mood. After 4-6 weeks, you’ll notice more hydrated skin, stronger nails, and relief from joint pain.

After 8-12 weeks there is a visible improvement in skin elasticity, reduction of fine wrinkles and a significant improvement in joint mobility. After 6 months or more, there is a long-term improvement in skin quality, stable joint health and overall younger appearance.

The combination of active ingredients in HEXXXA Pro-Age Collagen can accelerate these processes thanks to the synergistic action of all six ingredients.

When is the best time to start taking collagen?

For people in their 20s-30s, prevention is key – this is the ideal time to start taking collagen to maintain natural stores. In the 30-40 age group, the first visible changes appear and regularity is important with a focus on the skin and the first signs of aging.

Between the ages of 40-50, more intensive care combined with an active lifestyle focusing on joints and muscles is needed. For people over 50, collagen is a necessity, not a luxury – it supports bones, cartilage and represents complete regenerative care.

HEXXXA Pro-Age Collagen is suitable for all ages thanks to its complex formula that promotes collagen production, provides antioxidant protection and promotes regeneration at the cellular level.

What are the most common myths about collagen?

One of the most common myths is that collagen breaks down completely in the stomach and does not reach the tissues. In fact, good quality hydrolysed collagen has high bioavailability and is effectively absorbed, as proven by many scientific studies.

Another myth says that all collagens are the same. In fact, there are huge differences in quality, origin and processing. Not every product verified by customers actually contains the claimed amount of active ingredients, and not all forms of collagen have the same bioavailability.

Some people believe that collagen will help immediately. The reality is that results come gradually and you should expect at least 4-6 weeks of regular use. Another myth is that collagen is only for women – men have the same needs for healthy joints, strong bones and recovery, especially athletes.

What is the correct dosage and use of collagen?

For joint health, type II collagen in combination with glucosamine and chondroitin is recommended, with a minimum of 1000mg per day. For beauty and skin, type I collagen combined with vitamin C is ideal, with a dosage of 5-10g per day. For complete skin care and overall health, a combination of multiple types of collagen supplemented with antioxidants is best.

The best time to take collagen is in the morning on an empty stomach for best absorption, in the evening before bed to aid recovery, or after a workout for maximum usability, especially for athletes. Collagen dissolves best in cold or lukewarm water, it can be added to smoothies or yogurt, but it is not recommended to boil it as the high temperature destroys the active ingredients.

HEXXXA Pro-Age Collagen provides the optimal dosage of all active ingredients in one serving. It contains a total of 9700 mg of collagen (7000 mg beef + 2700 mg fish) plus 3000 mg glycine, which is the ideal amount for complete health and beauty support.

What substances promote the effectiveness of collagen best?

Vitamin C is absolutely essential for the formation of collagen in the body and without it, the body cannot produce collagen efficiently. Zinc promotes collagen synthesis and wound healing, while selenium acts as an antioxidant and protects collagen structures from damage.

Hyaluronic acid retains moisture in the skin and joints, complementing the effects of collagen. Biotin supports the health of hair, nails and skin. Manganese and vitamin C work together to produce collagen and maintain healthy bones and cartilage.

HEXXXA Pro-Age Collagen contains natural vitamin C from acerola, which is better absorbed than synthetic vitamin C. Resveratrol supports blood vessel health and has anti-aging effects, while astaxanthin provides the strongest antioxidant protection of any known natural substance.
