ALANINE

Alanine is an α-amino acid that is used in the biosynthesis of proteins. It is known to balance moisture levels in the skin, thus providing improved hydration.

AMINO ACIDS

The building blocks of the proteins that make up collagen and elastin — substances that give the skin its structural support. Ageing and a combination of external factors (including UV light and environmental toxins) reduce the level of amino acids in the body. Amino Acids are vital for healthy skin. They strengthen the immune system and maintain the skin’s hydration. They protect skin from free-radical damage and reduce signs of ageing.

ANTIOXIDANT

Any ingredient that reduces free-radical damage to the skin.

ARGININE

A critical building block of proteins, skin collagen and hair keratin. It helps blood vessels relax, so more oxygen-rich blood can circulate through your arteries. It helps to restore visible skin damage.

ASPARAGINE

Asparagine is a beta-amido derivative of aspartic acid and plays an important role in the biosynthesis of glycoproteins and other proteins. It is required for the synthesis of many important cellular proteins in normal human cells.

BIOTIN / VITAMIN H

Biotin is a water-soluble vitamin that's a part of the vitamin B family. It's also known as vitamin H. Aside from helping the body process fats and sugars, biotin helps to maintain and promote healthy looking hair, skin and nails. 

COLLAGEN

Collagen is a protein that is found almost everywhere in our bodies: skin, tendons, ligaments, bone, cartilage, blood vessels, teeth and more. This protein makes up 80 percent of the skin, and its fibres give skin its firmness and strength. Collagen naturally breaks down in our bodies over time but by taking a supplement you can help your body to keep up its Collagen levels. Collagen is made up of essential amino acids which help keep connective tissue, hair, skin and nails healthy.

CYSTEINE

The human body uses cysteine to produce the antioxidant glutathione, as well as the amino acid taurine. The body can also convert cysteine into glucose for a source of energy. Cysteine also plays a role in the communication between immune system cells.

FREE RADICALS

Highly unstable molecules created in the body by sunlight, cigarette smoke, and pollution that latch onto and damage cells in ways that can lead to roughness, sagging, and wrinkling.

FOLIC ACID / VITAMIN B9

Folic acid helps make healthy red blood cells, which carry oxygen around the body. If we do not have enough folic acid, the body can make abnormally large red blood cells that do not work properly. This causes folate deficiency anaemia, which can cause tiredness and other symptoms.

GLYCINE

Glycine is an amino acid that functions as a building block for certain proteins, most especially the collagen found in skin, ligaments, muscles, bones, and cartilage. It significantly improves skin elasticity, improves skin hydration and prevents water loss. In addition, Glycine stimulates the production of the serotonin, the "feel good" hormone that helps elevate mood, improve sleep quality, and enhance cognition and memory.

GLUTAMINE

Glutamine is an important amino acid with many functions in the body. It is a building block of protein and critical part of the immune system. It has a special role in intestinal health. Your body naturally produces this amino acid, and it is also found in many foods.

HISTIDINE

Histidine is an amino acid needed in humans for growth and tissue repair, Histidine is important for protecting nerve cells and is required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals.

HYALURONIC ACID

Hyaluronic acid is found naturally in the skin. It has the properties of combining collagen fibers and binding molecules of water, provides us with firm, moisturized and nourished skin. Interestingly, only one gram of hyaluronic acid can bind about six liters of water. An additional advantage of HA is that it can also alleviate inflammation. With age, however, its amount in the skin decreases, which leads to the formation of wrinkles.

HYDROLYZED COLLAGEN

Found in beauty supplements and drinks aiming to plump and hydrate the skin, these collagen proteins have been broken down into smaller peptides to make for easier absorption into the bloodstream.

HYDROXYPROLINE

Hydroxyproline is a major component of the protein collagen. Hydroxyproline is produced by hydroxylation of the amino acid proline. Hydroxyproline and proline play key roles in collagen stability.

HYDROXYLYSINE

Hydroxylysine, glycogenic amino acid uniquely found in collagen, the chief structural protein of mammalian skin and connective tissue.

ISOLEUCINE

Is considered to be a glucogenic amino acid, meaning those that the body can easily and quickly transform into the energy necessary for its functioning. This means that it can help one excercise longer and more intensively, but also to regenerate faster. It may help how hemoglobin is made. This is the oxygen-carrying pigment inside of red blood cells. It may help control blood sugar. It may also boost energy and endurance.

IODINE

The body needs iodine to make thyroid hormones. These hormones control the body’s metabolism and many other important functions.

LEUCINE

Leucine increases the degree and speed of protein utilization for muscle building.

LYSINE

Lysine appears to help the body absorb calcium, and it plays an important role in the formation of collagen, a substance important for bones and connective tissues including skin, tendons, and cartilage.

METHIONINE

Methionine is found in meat, fish, and dairy products. It plays an important role in the many functions within the body. It may also act as an antioxidant and helps to protect damaged tissues.

NIACIN

A form of Vitamin B3, Niacine helps to strengthen skin and improve elasticity whilst reducing redness.

PHENYLALANINE

Phenylalanine is an essential α-amino acid. Too little phenylalanine curbs physical and intellectual growth. 

PROLINE

Proline is a basic amino acid involved in the synthesis of collagen. L-proline allows to maintain healthy joints, stimulates the regeneration processes of joint cartilage and muscles, and supports the maintenance of good condition of the skin, hair and nails.

RETINOL

A derivative of vitamin A used to stimulate the turnover of skin cells and increase collagen production.

SELENIUM

It plays a critical role in metabolism and thyroid function and helps protect your body from damage caused by oxidative stress. What's more, selenium may help boost your immune system, slow age-related mental decline, and even reduce your risk of heart disease.

SERINE

L-serine is an amino acid essential for the synthesis of phosphatidylserine, which is a component of the membrane of brain cells (i.e., neurons). It can be produced in the body, including the brain, but an external supply from the diet is helpful in maintaining necessary levels.

TRYPTOPHAN

L-tryptophan is an essential amino acid that helps the body make proteins and certain brain-signaling chemicals. Your body changes L-tryptophan into a brain chemical called serotonin. Serotonin helps control your mood and sleep.

THREONINE

Threonine helps keep connective tissues and muscles throughout the body strong and elastic, including the heart, where it is found in significant amounts. It also helps build strong bones and tooth enamel, and may speed wound healing or recovery from injury.

TYROSINE

Tyrosine is used to improve alertness, attention and focus. It produces important brain chemicals that help nerve cells communicate and may even regulate mood 

VALINE

Valine helps stimulate muscle growth and regeneration and is involved in energy production

VITAMIN A

Is a key vitamin when it comes to the health of our skin, hair and nails. That is why it is often an invaluable component of skin and hair supplements. The use of vitamin A is particularly important for dry and acne-prone skin. It helps the skin to maintain an adequate level of hydration, thanks to which the skin is more elastic and softer. It also helps in the fight against signs of aging such as wrinkles. It proves helpful in reducing stretch marks or symptoms of flaky skin.

VITAMIN B12

Vitamin B12 helps to regulate the production of pigment in the skin, helping to prevent dark spots and pigmentation. It also assists the body with the metabolism of protein which, in turn, promotes the growth of healthy skin cells and helps to repair damaged skin.

VITAMIN B6

Vitamin B6 is required by the body for the development of red blood cells, cell production and protein metabolism, which assists with the growth and repair of the skin cells. It can also help to regulate some of the hormone irregularities which can cause acne, helping to contribute to clearer calmer skin. 

VITAMIN C

An antioxidant that boosts collagen production and inhibits pigment formation. It also contributes to reducing wrinkles and skin healing.

VITAMIN E (TOCOPHEROL)

This moisturizing antioxidant protects against free-radical damage.

ZINC

Zinc is needed for the proper growth and maintenance of the human body. It is found in several systems and biological reactions, and it is needed for immune function, wound healing, blood clotting, thyroid function, and much more.
