Collagen dietary supplements are clinically recognized for improving skin quality, firmness, and elasticity. This protein is known to help the skin age well by reducing wrinkles and preserving its radiance.
This article provides all the necessary information to start a collagen treatment with confidence, including the best way to take collagen, the recommended daily dose of marine collagen, when to take collagen, at what age to take collagen, and especially in what form and how to take collagen.
Summary
I. Understanding collagen
1. What is collagen?
Collagen is an essential protein present in the body, which plays a crucial role in the structure and health of the skin, bones, muscles, tendons, and ligaments. It is responsible for the firmness and elasticity of the skin.
Collagen has a particular structure characterized by a specific sequence of amino acids, notably glycine, proline, and hydroxyproline. This unique structure takes the form of a triple helix, also known as the alpha triple helix, where three polypeptide chains are tightly intertwined.
This triple helix structure gives collagen its stability and strength, which are essential for the durability of connective tissues.

2. The roles of collagen in the body
Collagen is an essential protein in our body, playing a crucial role in the structure of the skin, hair, nails, tendons, and cartilage. Its production decreases with age, which can lead to signs of aging and health problems.
Collagen supplements have become popular to help compensate for this decrease and improve skin and joint health.

3. Understanding collagen absorption
Before determining when to take collagen or at what time of day to take collagen, it is important to understand how our body absorbs this protein.
Collagen is generally available in powder, capsule, or liquid form.
When we consume collagen supplements, it is important to understand how this protein is absorbed by our body to gain all its benefits.
When collagen is ingested in the form of dietary supplements, it first goes through the digestion process.
Collagen proteins are broken down into smaller peptides and amino acids by digestive enzymes present in the stomach and small intestine.
This enzymatic hydrolysis is a crucial step, as whole collagen molecules are too large to be absorbed directly by the intestinal wall.
Once broken down into smaller peptides and amino acids, these fragments are absorbed by the cells of the small intestine through active and passive transport mechanisms.
These collagen fragments then enter the bloodstream and are distributed throughout the body.
The absorbed collagen peptides can then exert several beneficial effects.
They stimulate the connective tissue cells, called fibroblasts, to produce more endogenous collagen. Additionally, these peptides may have anti-inflammatory and antioxidant effects, which contribute to the overall health of connective tissues.
Scientific studies have shown that regular consumption of hydrolyzed collagen can improve skin elasticity, reduce wrinkles and joint pain, and strengthen hair and nails.
It is important to note that the effects can vary depending on the individual, the quality of the collagen supplement used, and the duration of consumption.
In summary, the process of collagen absorption involves its breakdown into peptides and amino acids in the digestive system, followed by their intestinal absorption and distribution throughout the body. These collagen fragments can then contribute to the synthesis of new collagen and the overall health of connective tissues.
4. The decrease in collagen production with age
Indeed, from the age of 25, collagen production decreases, leading to the appearance of signs of aging such as wrinkles, fine lines, skin sagging, loss of volume, and elasticity.
These changes can also manifest in the body as joint problems, tendon issues, poor assimilation, and digestive disorders.
From 40 years old, the body produces about 1% less collagen each year. This means the body has less collagen to support the skin, joints, and connective tissues.
At the age of 50, we would have used up half of our collagen capital.

II. When to take collagen?
1. Depending on age: collagen production decreases over time
The time to take collagen depends on age, as the natural production of collagen decreases over time. At what age should you take collagen?
Indeed, from the age of 25, collagen production decreases, leading to the appearance of signs of aging such as wrinkles, fine lines, skin sagging, loss of volume, and elasticity.
These changes can also manifest in the body as joint problems, tendon issues, poor assimilation, and digestive disorders.
From 40 years old, the body produces about 1% less collagen each year. This means that the body has less collagen to support the skin, joints, and connective tissues.
At the age of 50, we would have used up half of our collagen capital.
2. Depending on needs: skin, joints, hair, and nails...
Some individuals feel the need to take collagen due to specific issues such as joint pain or skin problems caused by a decrease in collagen in their body.
One can then opt for marine collagen supplementation.
Here are some situations in which a marine collagen treatment can be beneficial:
To improve skin beauty in cases of dry skin, dehydration, to restore the skin's radiance and volume, to regain skin firmness, reduce the appearance of wrinkles and fine lines, prevent early wrinkles, and achieve a bright and even complexion.
To support sports practice or bodybuilding by promoting the development of lean muscle mass and facilitating recovery after exertion.

To enhance the beauty of hair and nails by providing shine and vitality to the hair, especially in combination with complementary active ingredients for hair beauty.
3. From when should it be consumed?
It is possible to start collagen supplementation from the age of 25 as a preventive measure. By improving skin quality, collagen supplementation can delay the appearance of the first signs of aging.
In certain cases, such as smoking, a stressful lifestyle, repeated exposure to UV without sunscreen, or very intense physical activity, it may be wise to start collagen supplementation from the age of 25 to prevent premature degradation of collagen proteins in the body.

III. How to consume it?
1. What dose to take each day?
The recommended doses of collagen generally range from 3 to 10 grams depending on individual needs.
To support skin health, a dose of 2g may be sufficient, while for joint problems, it is generally recommended to take between 4 and 10g.
In the case of specific needs such as intense healing, higher doses may be necessary.
However, the quality of collagen is essential. No matter the dose, as long as the collagen is well hydrolyzed, of good quality, and the results are clinically proven.
It is better to choose a small dose of quality rather than a high dose of low-quality and poorly absorbable collagen.
2. At what time of day should it be taken?
There is no specific recommended time to take collagen, it depends on individual preferences and lifestyle.
Some prefer to take it in the morning, while others add it to their evening routine.
To achieve better results, it is important to be consistent in taking dietary supplements.
It is therefore ideal to find a way to easily integrate it into your daily routine, for example by taking it at breakfast, adding it to your morning coffee, mixing it into an herbal tea in the evening, or consuming it in a post-workout drink if you are an athlete.
It will also depend on the form of collagen you consume.
3. Should it be taken in the morning or in the evening?
Some people choose to take collagen in the morning on an empty stomach for better absorption, while others prefer it before or after exercise. Some experts also suggest taking collagen before bedtime to promote cellular regeneration during sleep.
a. In the morning on an empty stomach
Taking collagen in the morning on an empty stomach can promote better absorption of collagen peptides, as the stomach is empty and digestive enzymes can act more effectively.
b. Before or after exercise
Taking collagen before or after exercise can help support muscle recovery and promote joint health. Collagen peptides can be quickly absorbed and used by the body to repair connective tissues.
c. Before bedtime
Taking collagen before bed can promote cellular regeneration during sleep. The body repairs and regenerates itself at night, and collagen peptides can support this process.
4. Impact of fasting on collagen absorption
Intermittent fasting, an increasingly popular practice, involves alternating between periods of fasting and eating.
This method can have various effects on the body, including on nutrient absorption.
When it comes to taking collagen, the timing of consumption during a fasting cycle can influence its effectiveness.
- Improvement of Absorption
During a fasting period, the stomach and intestines are empty, which can facilitate the absorption of supplements when consumed at the end of the fast. When you take collagen on an empty stomach, there is no competition with other nutrients for absorption. This can allow for a faster and more efficient assimilation of collagen peptides and amino acids in the digestive system.
- Maximization of Regenerative Benefits
Fasting has been associated with various health benefits, including improved cellular regeneration and reduced inflammation. Taking collagen after a fasting period could enhance these effects. Collagen provides the amino acids necessary for tissue repair, and fasting may potentially increase the cells' sensitivity to these nutrients, thereby optimizing the regeneration process.
- Timing and Consumption
For those who practice intermittent fasting, consuming collagen just after the fasting period can be particularly beneficial. For example, if you follow a 16/8 fasting pattern (16 hours of fasting followed by 8 hours of eating), taking collagen at the end of the 16 hours can maximize its absorption and effects.
- Practical Considerations
It is important to note that, although fasting can improve collagen absorption for some people, everyone reacts differently to fasting and supplements. It is advisable to start slowly and monitor how your body responds. If you have specific health concerns or pre-existing medical conditions, consult a healthcare professional before incorporating collagen and fasting into your routine.

Fasting can potentially improve collagen absorption by reducing competition with other nutrients and increasing cells' sensitivity to essential amino acids. Taking collagen after a fasting period can therefore maximize its regenerative and tissue repair benefits. However, it is crucial to listen to your body and adjust collagen intake according to your individual needs and reactions.
5. How long does a collagen treatment last?
The duration of a collagen treatment can vary depending on the desired results and specific needs. Some people opt for a treatment lasting a few months, while others prefer long-term use.
Clinical studies generally suggest a program of 2 to 6 months to achieve lasting benefits from collagen.
A period of three months can already allow for a significant improvement in skin elasticity and its beauty.
At D-LAB, you can consume collagen treatments all year round according to your needs.
IV. The different available forms
1. Powder
The powdered form of collagen allows for high bioavailability, optimal digestibility and absorption, and can be used in various ways.
Marine collagen powder is mainly composed of 100% hydrolyzed collagen peptides, like the one offered by D-LAB.
Among all sources of collagen, marine collagen powder is considered one of the most easily absorbed by the body, as its structure is similar to that of human collagen.
How to take collagen powder?
Collagen powder is a convenient and versatile form of supplementation. Here are some ideas to easily incorporate it into your daily routine:
Mixed with drinks: You can mix collagen powder into various drinks such as water, fruit juice, tea, or coffee. Make sure to stir well to avoid lumps.
In smoothies or shakes: Add a teaspoon or tablespoon of collagen powder to your usual protein smoothies or shakes. This can be especially convenient for people following a protein diet or leading an active lifestyle.
In culinary recipes: Incorporate collagen powder into your favorite recipes, such as soups, sauces, desserts, or even homemade energy balls. Choose dishes that will not be cooked at too high temperatures, as excessive heat can degrade collagen.
Sprinkled on food: You can also sprinkle collagen powder on foods such as yogurts, cereals, salads, or fruits. It's a great way to discreetly incorporate it into your daily diet.
D-LAB collagen powders allow you to meet your collagen needs as well as various active ingredients depending on your current issue: hair, slimming, joints, digestion, or even sun care.
2. Tablets
Collagen tablets are, for some, easier to use than powders. They are to be added to your daily routine, morning or evening, depending on your schedule.
This unique complex contains 94% marine collagen combined with 6% elastin fibers in proportions equal to those of the essential components of our skin. To ensure maximum bioavailability, D-LAB has selected a patented and hydrolyzed collagen, making it perfectly absorbable by the body.
This balance helps stimulate the biosynthesis of the main components of the dermis to tone sagging areas and effectively combat the signs of aging.
By combining the two main components of our dermis, the Collagen Absolute has a proven synergistic anti-wrinkle effect demonstrated by a clinical study: elastin fibers provide skin suppleness while collagen stimulates the production of new collagen in the body to protect and hydrate the epidermis as a whole.
3. Foods rich in collagen
Some foods contain collagen, such as bone broth, fish, eggs, and goji berries contain nutrients that promote collagen production.
Some traditional dishes cooked for a long time are naturally rich in collagen, such as bone broth, pot-au-feu, fish and shellfish broths, as well as bone marrow and gelatin.
For vegetarians or vegans, it is preferable to choose foods that stimulate collagen synthesis and help its regeneration, such as those rich in vitamin C (sprouted seeds, peppers, kiwi, berries and small red fruits, citrus fruits, parsley). Spirulina is also known to stimulate collagen synthesis.
4. Collagen-based creams and treatments
To complement and enhance the action of collagen dietary supplements, you can incorporate collagen-containing skincare products into your beauty routine (collagen concentrated serums, collagen creams, etc.).
As an active cosmetic ingredient, collagen acts as a protective shield for the skin, maintaining its hydration and protecting it from external aggressions.
It also enhances skin hydration, gives a fresh and plump complexion, and improves the texture and elasticity of the skin.
Some products also stimulate the natural production of collagen, thereby promoting skin health and youthfulness, such as vitamin C.
