Collagen is one of the most important proteins in the human body. It is responsible for skin elasticity, joint strength, the condition of hair and nails, and the proper functioning of connective tissue. As we age, natural collagen production declines, which can lead to the appearance of wrinkles, weakened joints, and a deterioration in the appearance of the skin. It is no wonder that collagen supplements are becoming increasingly popular. But how do you choose the best product that will actually deliver the desired results? Below, we outline the key aspects to consider.

Type of Collagen – Key to Effectiveness

The first and most important criterion when choosing a supplement is the form of collagen. The most easily absorbed form is hydrolysed collagen (collagen hydrolysate). During hydrolysis, large collagen molecules are broken down into smaller peptides, making them easier for the body to absorb and utilise.

Collagen is also available in the form of gelatin or unprocessed collagen protein, but their bioavailability is much lower. If you want real results, hydrolysed collagen should be the foundation.

Source of Collagen – Marine, Bovine or Chicken?

Collagen in supplements can come from different sources, each with specific benefits and uses.

• Fish (marine) collagen is extracted from fish skin and bones. It is often chosen by people who want to support the appearance of skin, hair, and nails. It has a light peptide structure, which favours good absorption, and is valued for its neutral composition and lower digestive load.
• Bovine collagen comes from bovine tissue and mainly contains type I and III collagen, naturally present in skin, bones, tendons, and muscles. It is often chosen by physically active individuals or those looking to support joints, the musculoskeletal system, and overall tissue resilience. Its versatility makes it suitable for both “joint” supplements and products that improve skin condition.
• Chicken collagen is a source of type II collagen, important for maintaining the structure of joint cartilage, and is often included in supplements targeting joint support.

Choosing the right collagen source should be tailored to individual needs and desired effects. Regardless of the source, the quality of the raw material, degree of hydrolysis, and combination with other supporting ingredients are key factors.

Vitamin C – an Essential Component for Effective Supplementation

Vitamin C is a very important element of a good collagen supplement. Without it, collagen synthesis in the body is significantly limited. Vitamin C participates in enzymatic processes responsible for forming new collagen fibres, so its presence in the supplement greatly enhances its effectiveness.

It is best when vitamin C is present in a stable and easily absorbed form, such as L-ascorbic acid or its derivatives. A collagen supplement without vitamin C may not deliver the expected results.

Collagen Dosage – How Much is Enough?

Another consideration is the collagen content per daily serving. Effective supplements usually provide between 2.5 g and 10 g of hydrolysed collagen per day. Too low a dose may not produce noticeable effects, while very high amounts do not always guarantee better results. Consistency and an appropriately chosen portion are key.

Product Composition – The Shorter, the Better

Reading labels carefully is important. A good collagen supplement should have a simple and transparent composition, without unnecessary colourings, preservatives, or artificial sweeteners. Additional supporting ingredients, such as zinc, copper, biotin, or hyaluronic acid, can be beneficial, but should not replace the essential components: collagen and vitamin C.

Supplement Form – Powder, Capsules or Liquid?

Collagen supplements come in various forms, allowing them to be tailored to individual preferences and lifestyles. Each has its advantages but differs in convenience and effectiveness.

• Powdered collagen is a popular choice for those who want to deliver larger doses. It can easily be added to water, smoothies, yoghurt, or coffee, offering flexibility in supplementation. A further benefit is precise portion control. The downside is the need to prepare a drink daily and the sometimes specific taste.
• Capsules or tablets are primarily convenient. They are easy to take and require no preparation, which suits people with busy lifestyles. However, this form usually contains smaller amounts of collagen per serving, and achieving an effective dose may require taking multiple capsules daily.
• Liquid collagen is often considered the most effective form of supplementation. It has high bioavailability because it does not need to be dissolved or broken down in the digestive tract as intensively as solid forms. Active ingredients can therefore be absorbed more quickly and effectively. Additionally, supplements like collagen shots usually combine collagen with vitamin C and other supporting ingredients, offering convenience and no need for portion measurement.

In summary, the choice of supplement form should consider both user preferences and desired effects. If effectiveness and rapid absorption are a priority, liquid form may be the best choice, while powder and capsules remain good alternatives for those who value flexibility or maximum convenience.

Conclusion – How to Choose a Good Collagen Supplement

When choosing a collagen supplement, it is important to consider several key criteria: the form of collagen (hydrolysate for better absorption), the presence of vitamin C to support collagen synthesis, the appropriate dose of active ingredients, and ease of use. Equally important is a transparent composition and the absence of unnecessary additives, which supports daily, consistent supplementation.

One example of a product that combines these features is Primabiotic Collagen – liquid collagen supplement prepared in ready-to-use shots. Each bottle contains 10,000 mg of hydrolysed collagen and a range of vitamins, including vitamin C, which supports collagen synthesis, as well as B, D, E, and A vitamins, which contribute to healthy skin, hair, nails, and immune function.

In conclusion, if you prioritise high ingredient bioavailability, convenience, and a supplement that provides both a good dose of collagen and supporting vitamins, the liquid form may be one of the best options on the market. Regular use, combined with a healthy diet and lifestyle, maximises the chances of noticeable results – from improved skin elasticity to support for hair, nails, and joints.
