Collagen: A Complete Guide. Why You Need It, Which One to Choose, and How to Take It for Maximum Effects

Collagen is the most abundant protein in the human body. It makes up approximately 30% of all proteins and is responsible for the strength, elasticity, and flexibility of connective tissue. Skin, joints, ligaments, bones, nails, and hair all depend on collagen. After 25–30 years, collagen production begins to decline. By age 40, the body loses up to 30% of its collagen fibers, and by age 60, more than 50%. This manifests as wrinkles, sagging skin, joint pain, brittle nails, and hair loss. In this article, we'll explore what collagen is, its different types, who needs it, how to take it correctly, and why HEISEN st products are the best choice for your health and beauty.

What is collagen and why is it important?

Collagen is a fibrillar protein that forms the basis of connective tissue. It provides firmness to skin, cushioning to joints, strength to bones, and elasticity to blood vessels. With age, collagen synthesis slows due to:

• natural aging;
• exposure to ultraviolet radiation;
• smoking and alcohol;
• high sugar levels (glycation);
• chronic stress;
• lack of vitamins and minerals.

There are three ways to replenish your reserves:

1. Stimulate production through nutrition (bone broths, fish, eggs) and vitamins (C, zinc, copper).
2. Take hydrolyzed collagen supplements.
3. Use cosmetic procedures (injections, care).

The most effective and affordable method is regular intake of high-quality hydrolyzed collagen.

Types of Collagen: Which One Is Needed for What?

There are over 20 types of collagen in the human body, but 90% are types I, II, and III. Type I is the most common (80–90%). It is responsible for the strength of the skin, bones, tendons, ligaments, nails, and hair. Its deficiency leads to wrinkles and loss of elasticity. Type II is the main component of articular cartilage. It provides cushioning and protects joints from wear and tear. Type III is often found together with type I. It is responsible for the elasticity of blood vessels, intestines, and muscles. Marine collagen (type I) is obtained from the skin, scales, or bones of fish. It is considered the most bioavailable due to its small molecular structure. It is especially effective for skin, hair, and nails. Bovine collagen (types I and III) is from the skin and bones of cattle. It works well to support the skin, ligaments, and tendons. Chicken collagen (type II) is from the cartilage of chickens. The best choice for joints and osteoarthritis.

The Benefits of Collagen: Scientific Evidence

Skin health

Meta-analyses show that taking hydrolyzed collagen for 4–12 weeks increases skin elasticity, improves hydration, and reduces wrinkle depth. This effect is achieved by stimulating fibroblasts—the cells that produce natural collagen.

Joint support

For osteoarthritis and joint pain, collagen supplementation (especially type II) reduces inflammation and slows cartilage breakdown. Studies confirm pain reduction and improved mobility after just three months.

Strength of bones

Collagen forms the basis of the bone matrix. Taking supplements in combination with calcium and vitamin D improves bone mineral density, which is especially important for postmenopausal women.

Strengthening nails and hair

Regular intake of collagen reduces brittleness of nails, promotes their growth, and also improves hair structure, reducing hair loss.

Gut health

Collagen amino acids (glycine, proline, glutamine) support the integrity of the intestinal barrier and help with leaky gut syndrome.

Which collagen is best: what to look for

1. Form: Hydrolyzed Collagen. Hydrolysis is the breakdown of long collagen chains into short peptides. This form is almost 100% absorbed, unlike native collagen, which is poorly digested. Look for the words "hydrolyzed" or "collagen peptides" on the packaging. 2. Molecular Weight : Optimal: less than 3,000 daltons. The smaller the molecules, the faster they are absorbed into the bloodstream and delivered to tissues. Marine collagen typically has a lower molecular weight. 3. Collagen Types : Choose based on your goals:

• For skin, nails, hair – type I (marine or bovine).
• For joints – type II (chicken or complex with type II).
• For the whole body – complex I+II+III.

4. Additive-free composition: High-quality collagen should not contain sugar, flavorings, or fillers. The purer the composition, the better the results. 5. Additional components: The effectiveness of collagen is enhanced by vitamin C (necessary for the synthesis of natural collagen), hyaluronic acid, zinc, and sulfur (MSM). These complex formulas work synergistically.

How to take collagen correctly

Dosage

• Prevention: 5–6 g per day.
• Medicinal purposes (pronounced problems with skin, joints): 10–15 g per day.
• Course duration: minimum 3 months. Collagen accumulates in tissues gradually, with the first visible changes usually noticeable after 4–8 weeks.

It's best to take collagen on an empty stomach or between meals to avoid competing with other proteins for absorption. Ideally, take it in the morning 30 minutes before breakfast or in the evening 2 hours before bed. What to combine it with

• Vitamin C is essential. It participates in the hydroxylation of proline and lysine; without it, collagen synthesis is impossible.
• Hyaluronic acid – enhances skin hydration.
• Zinc and copper are cofactors in collagen synthesis.
• What NOT to combine with: hot drinks (high temperature destroys peptides), coffee (caffeine reduces absorption).

Release form

• Powder: easy to mix with water or juice, absorbs faster.
• Capsules: convenient for dosing, no taste.
• Liquid collagen: fast absorption, but often contains preservatives and sugar.
