Fortigel® Collagen – what is it and how does it work?

Fortigel® is a proprietary, patented form of hydrolyzed collagen, designed to support the health of joints, tendons and the musculoskeletal system. This bioactive collagen peptide was developed by GELITA AG, one of the global leaders in the field of collagen proteins. Thanks to numerous clinical studies confirming its effectiveness, Fortigel® has gained recognition among doctors, physiotherapists and dietary supplement manufacturers around the world.

Composition and mechanism of action of Fortigel®

Type II collagen hydrolyzate - the structural foundation of cartilage

Joint cartilage consists mainly of type II collagen, which is responsible for its elasticity, strength and resistance to pressure. Fortigel® contains precisely selected collagen peptides that are enzymatically digested into a form that is easily absorbed by the body. Their low molecular weight (3–6 kDa) allows for rapid absorption from the gastrointestinal tract and transport to target tissues – especially cartilage.

Stimulation of extracellular matrix synthesis

The peptides contained in Fortigel® act as metabolic signals, stimulating chondrocytes (cartilage cells) to produce:

• Type II collagen
• Proteoglycans (e.g. aggrecan)
• Glycosaminoglycans

Thanks to this, Fortigel® not only replenishes collagen deficiencies, but also initiates regenerative processes in the joints.

Supporting formula - not only collagen

Although the foundation of 4+ FLEX mobility+ 500g is Fortigel®, the product may also contain other supporting substances, such as vitamin C, known for its contribution to the proper formation of collagen. Many preparations designed to support joints also contain minerals (e.g. manganese, copper), which can participate in maintaining the elasticity of connective tissue.

Strengthening the supplement formula with supporting vitamins and elements is aimed at creating a synergistic effect, thanks to which joint support can be multi-faceted. This is why 4+ FLEX mobility+ 500g is famous for its comprehensive approach to the condition of joints and their proper functioning, especially in the context of an active lifestyle.

Other ingredients of the dietary supplement for jointsand their effects

Sodium Hyaluronate - 115 mg - including hyaluronic acid - 100 mg-  is one of the most valuable discoveries in the field of joint health support. This compound, which is the sodium salt of hyaluronic acid, naturally occurs in synovial fluid, where it is responsible for its viscosity and elasticity. Hyaluronate supplementation acts as a lubricant for joints - it improves their mobility, reduces friction and reduces the feeling of stiffness.

Calcium - 120 mg- is not only a building block of bones, but also a key mineral for healthy and durable joints. Although mainly associated with the prevention of osteoporosis, its role in the musculoskeletal system is much broader. Calcium deficiency can lead to weakening of the structures supporting the joints, which in turn increases the risk of injury and chronic pain.

Magnesium - 56.3 mg- is an irreplaceable element for muscles, bones and joints. Its action goes far beyond reducing cramps - it participates in the synthesis of structural proteins, including collagen, which is the main component of joint cartilage. Magnesium is also responsible for proper neuromuscular conduction, which has a direct impact on movement control and protection of joints from overload.

Manganese - 0.6 mg- often overlooked, manganese plays a key role in maintaining healthy joints and bones. This trace element supports the synthesis of glycosaminoglycans, i.e. compounds that build joint cartilage. Without the right amount of manganese, the repair processes in the joints slow down, and the cartilage itself loses its elasticity and ability to cushion.

Copper - 0.3 mg- is a micronutrient that is of great importance for the elasticity and strength of joints. It participates in the formation of cross-links in collagen and elastin - two proteins responsible for the elasticity of connective tissues, including joint cartilage, tendons and ligaments.

Vitamin C - 280 mg- a true foundation of joint health - not only as a strong antioxidant, but above all as an essential component of collagen synthesis.

Vitamin D - 2.5 µg - is not only an ally of immunity, but also a key player in maintaining bone and joint health. Its main task is to regulate calcium-phosphate metabolism - without it, calcium is not properly absorbed, which weakens the structure of bones and joints.

Why does the quality of a joint dietary supplement matter?

There are many preparations on the market that promise quick support in the field of joint health. However, not all products are characterized by high quality and effectiveness. It often happens that the forms of collagen or other key nutrients contained in them are more difficult for the body to absorb. The use of high-quality, standardized and patented ingredients (such as Fortigel®) is a guarantee that:

• The preparation has been subjected to multi-stage tests and quality controls.
• The production process is carried out in compliance with safety standards
• The ingredients are highly absorbable, and their quality is confirmed by a reliable source.

4+ Nutrition is recognized in the dietary supplement industry because it focuses on transparency of composition and ensures that key components are characterized by real action.
