What is collagen and what does it do?

Collagen is a protein human body makes naturally. It makes up about a third of all of the protein in human body. Collagen is the most abundant protein in the body, found in the bones, muscles, skin, and tendons. It’s essential for healthy joints. It also keeps skin elastic to lessen wrinkles. For that reason, collagen supplements are popular.

Endogenous collagen is natural collagen, synthesized by the body. Exogenous collagen is synthetic. It comes from an outside source, such as supplements.
Endogenous collagen has a number of important functions. Breakdown and depletion is linked to a number of health problems. Exogenous collagen is used for medical and cosmetic purposes, including the repair of body tissues.

What is collagen?

Collagen is the most abundant protein in your body, accounting for about a third of its protein composition.
It’s one of the major building blocks of bones, skin, muscles, tendons, and ligaments. Collagen is also found in many other body parts, including blood vessels, corneas, and teeth. Collagen’s strong fibers work like glue to hold things together in your body: muscles, bones, tendons, ligaments, organs, and skin.

There are at least 16 different types of collagen. The four main types are type 1,2,3 and 4, but 80 to 90 percent of them belong to types 1, 2, and 3. These different types have different structures and functions. Each one has a different job:

Type I provides structure to skin, bones, tendons, fibrous cartilage, connective tissue, and teeth.

Type II helps to make cartilage, the flexible tissue between bones and in your ears and nose.

Type III helps supports the structure of muscles, organs, and arteries.

Type IV helps with filtration and is found in layers of the skin.

What does collagen do?

Collagen is secreted by various cells, but mainly by connective tissue cells. It is found in the extracellular matrix. This is an intricate network of macromolecules that determines the physical properties of body tissues. A macromolecule is a molecule containing a large number of atoms.

In the dermis collagen helps form a fibrous network of cells called fibroblasts, upon which new cells can grow. It also plays a role in replacing and restoring dead skin cells. Some collagens act as protective coverings for delicate organs in the body, such as the kidneys.

With age, the body produces less and lower-quality collagen. One of the visible signs of this is in your skin, which becomes less firm and supple. Wrinkles form, and cartilage also weakens with age, stiff tendons or ligaments. Women experience a dramatic reduction in collagen synthesis after menopause. By the age of 60 years, a considerable decline in collagen production is normal.

What hurts the collagen levels?

Three main things will lower your collagen levels: sunlight, smoking, and sugar.

  • Too much exposure to ultraviolet light makes its fibers unravel. This can lead to sun damage, such as wrinkles.
  • Many of the chemicals in cigarette smoke can damage it, which can make skin sag and wrinkle.
  • Sugar causes the fibers to cross-link and tangle. This makes your skin less elastic over time.
Effects of Whey Supplementation

Effects of Whey Supplementation

People use Whey Protein for a variety of reasons, including to build muscle, lose weight or simply improve their overall health and wellness. The best-known use of whey protein supplements is for the purpose of increasing muscle mass and strength.

Whey protein has been shown to be particularly effective at increasing muscle growth when consumed right before, after or during a workout. Muscle protein synthesis is usually maximized in the time period after training.

The ways by which whey protein promotes muscle or strength gain includes:

  • provides protein and amino acids, which serve as building blocks for increased muscle growth,

  • increases the release of anabolic hormones that can stimulate muscle growth, such as insulin,

  • high in the amino acid leucine, which is known to stimulate muscle protein synthesis at the molecular and genetic level,

  • whey protein is absorbed and utilized very quickly compared to other types of protein.

Unless your diet is already lacking in protein, supplementing with whey protein is unlikely to have a significant effect on your results.
If you’re already eating plenty of high in quality protein products as meat, fish, eggs and dairy — the benefits of adding whey will probably be minimal.

Protein has been shown to aid weight loss by boosting metabolism and reducing appetite. Whey protein can help increase fat loss while preserving lean muscle mass.

Whey is more than just a high-quality protein source; it also contains other beneficial nutrients.

Beyond just muscle, strength and leanness, whey protein may provide numerous other health benefits: lowering blood pressure, blood sugar and reducing symptoms of stress and depression, protects against cancer, reduces symptoms of hepatitis, increases bone mineral density.

Whey protein is an exceptionally healthy way to add more protein to your diet. It’s a quality protein source that is absorbed and utilized efficiently by the human body.


This is particularly important for athletes or people who need to gain muscle mass and strength while losing fat.

Basic about Whey Protein

Basic about Whey Protein

Whey protein contains an incredible range of essential amino acids, which are absorbed quickly. Whey protein is more than just protein. It contains many other nutrients, some with potent biological effects.

Numerous studies show that it can help you increase strength, gain muscle and lose significant amounts of body fat.

What Is Whey Protein?

Whey protein is the protein contained in whey, the watery portion of milk that separates from the curds when making cheese. Milk actually contains two main types of protein: casein (80%) and whey (20%).

Whey protein doesn’t taste very good on its own, which is why it’s usually flavored. It’s important to read the ingredients list, as some products may have unhealthy additives like refined sugar. Most flavored whey proteins are also rather delicious and can be used to add an incredible taste to healthy recipes like smoothies.

Proteins are the main building blocks of the human body. They’re used to make various important things, including tendons, organs and skin, as well as hormones, enzymes, neurotransmitters and various molecules.

Proteins are also the building blocks of the contractile elements in our muscles. They’re assembled from amino acids, smaller molecules that are linked together like beads on a string.

Some amino acids are produced by our body’s cells, while others are supplied by the food we eat. The ones that we must get from foods are termed essential amino acids.

Proteins that supply all nine essential amino acids are the best, and whey protein is loaded with them. It’s particularly high in important branched-chain amino acids like leucine, and also contains a high amount of cysteine. Studies show that leucine is the most anabolic (growth-promoting) amino acid, and cysteine can help boost levels of the cellular antioxidant glutathione.

Whey protein appears to be particularly effective at stimulating growth in humans. In fact, human breast milk is 60% whey, compared to 20% in cow’s milk

Types of Whey Protein

The main types of whey protein are concentrate, isolate and hydrolysate. They can vary in protein content, taste, digestibility and price.
There are three primary types of whey protein:

  • Whey protein concentrate (WPC) contains low levels of fat and low levels of carbohydrates. The percentage of protein in WPC depends on how concentrated it is. Lower end concentrates tend to have 30 percent protein and higher end up to 90 percent.
  • Whey protein isolate (WPI) is further processed to remove all the fat and lactose. WPI is usually at least 90 percent protein.
  • Whey protein hydrolysate (WPH) is considered to be the “predigested” form of whey protein as it has already undergone partial hydrolysis – a process necessary for the body to absorb protein. WPH causes a 28–43% greater spike in insulin levels than isolate. WPH doesn’t require as much digestion as the other two forms of whey protein.  Also, Whey protein hydrolysate is commonly used in medical protein supplements and infant formulas because of its improved digestibility and reduced allergen potential.

The proteins in whey are of a very high quality. They’re loaded with essential amino acids.
