Joint Nutrition



The practitioner’s choice of liquid joint supplement.

Cartonica 6K takes the guess work out of choosing a joint supplement.  With 6,000mg of nutrients (6K) dissolved in an easy to take liquid, no tablet supplement comes anywhere close.

PACKED WITH COLLAGEN II – Of the 6,000mg, 5,000mg of the blend is Type II collagen which accounts for 60% of the dry weight of cartilage found in joints.  Combined with other nutrients to support joint health, Cartonica leaves other supplements in the shade.

Cartonica is the advanced liquid joint supplement which leads health conscious consumers away from tablets.

The reason is simple.  Tablet supplements can only contain a limited quantity of nutrients, typically a maximum of 1,000mg per tablet.  Some tablets, which usually sell on price, require consumers to take two or even three tablets per day and even then the nutritional content of those tablets falls well short of what is contained in Cartonica.

Cartonica was researched for supply in clinics.  It has a huge 6,000mg joint formula per serving including more type II collagen than the leading UK tablet joint supplement.  

No tablet supplement comes close to Cartonica and that is before you consider the absorption benefits of having nutrients dissolved in a liquid.

You can see the bottle label for a list of ingredients in Cartonica or click the ingredients tab.  Working with clinics, at Clinic Nutrition we also show the published evidence relating to each ingredient in Cartonica.

Some Cartonica highlights:

  • Collagen Type II is a protein made from amino acids. It accounts for 60% of the dry weight of joint cartilage. Type II collagen represents 90-95% of the total collagen in joints. The body uses amino acids and nutrients to make collagen and cartilage in joints.
  • Glucosamine Sulphate is present in the fluid which provides lubrication around joints and is a building block of cartilage.
  • Chondroitin Sulphate is a component of cartilage which retains water and is intended to enhance shock-absorbing properties.
  • MSM (Methylsulfonylmethane) contains sulphur, a building block for complex proteins called glycosaminoglycans which are in the structure of cartilage.
  • L-Carnitine is converted in the body to acetyl-L-carnitine (ALC). ALC helps maintain cell energy and protects against oxidative damage.

Cartonica also contains Vitamin C which helps the body form and repair cartilage, Vitamin D which allows the body to absorb calcium from our blood stream to make bone and Turmeric which is regarded as a natural anti-inflammatory.

Cartonica is a food supplement.  It is available in clinics primarily because it takes away the confusion for patients of trying to choose between so many different joint supplements.

Cartonica is a single product with not only more nutrients and bioavailability than tablets but it is also pleasurable and easy to consume.

Most people drink Cartonica at or before breakfast.  It comes with a handy measuring cap and you can drink Cartonica neat or diluted with water.  Whatever suits you best.

Each bottle is 500ml which represents a 33 day supply.  Once opened, just keep it in the fridge.

Upgrade your joint nutrition and start enjoying the benefits of Cartonica for yourself.

Important Allergen Advice: Contains extracts from shellfish. See label image for full list of ingredients.
Not suitable for vegetarians: Type II collagen which is a major component of articular cartilage in joints is a bovine extract.

Cartonica nutrients supporting joint health

Below is a description of each ingredient in the Cartonica blend, their purpose in joint health along with references to published studies.

  • Vitamin B12

Vitamin B12 or cobalamin is a water-soluble vitamin that plays a key role in various physiological functions. For example, healthy production of red blood cells, maintenance of nerve function and proper regulation of mood.

In addition, it also supports joint health in two ways; first, lowers the risk of bone fracture,  second, it helps normalise homocysteine levels, which may be increased in patients with joint disease. (1,2)

  • Vitamin C

Vitamin C or ascorbic acid is a water-soluble vitamin with powerful antioxidant properties. It binds to the harmful chemical species called free radicals and counteracts their negative effects.

Human studies have shown that vitamin C helps prevent cartilage loss and slows down the progression of joint diseases. (3,4)

  • Vitamin D3

Vitamin D3 or cholecalciferol is a fat-soluble vitamin. It is key to maintaining optimal bone health as it helps your body absorb calcium and phosphorus from your diet.

It helps prevent bone loss by preventing the breakdown of bone tissues and subsequent release of calcium into the bloodstream. In addition, vitamin D supplementation (either oral or using an injection) increases bone mass and reduces the risk of falls. (5,6)

  • Turmeric

Turmeric is a spice of the ginger family. It contains a powerful anti-inflammatory and antioxidant known as curcumin.

Turmeric is a safe and highly effective natural treatment for several joint diseases. Curcumin improves joint tenderness and swelling. It reduces inflammation by blocking the activity of pro-inflammatory substances, prevents cartilage degradation, and counteracts cellular damages. (7,8)

  • Green Tea Extract

Green tea extract is a rich source of potent antioxidants, polyphenols. While green tea extract is sometimes used in weight loss programmes, one of the polyphenols, epigallocatechin-3 gallate (EGCG), has been shown to ve beneficial for joint health.

EGCG helps prevent and alleviate the symptoms of joint disease through its anti-inflammatory activity. It works by blocking the activity of inflammatory substances in the cells of cartilage. (9)

  • Hydrolysed Collagen Type II

Hydrolysed collagen type II has been widely studied as a potential treatment for various joint health conditions.

Naturally-occurring type II collagen is a major component of joint cartilage. Joint diseases such as autoimmune arthritis cause a gradual loss of collagen type II and proteoglycans. This results in pain, tenderness, stiffness, and limited mobility. (10)

Laboratory study shows that administration of hydrolysed collagen type II to the culture medium stimulates the production as well as secretion of type II collagen in cartilage tissues. Moreover, ingested hydrolysed collagen type II accumulates in cartilage where it stimulates the synthesis of macromolecules that are necessary for maintaining proper functioning of the joints. (11,12)

  • Glucosamine Sulphate

Glucosamine is a naturally-occurring amino acid that plays a key role in the growth and repair of joint cartilage.

Oral glucosamine sulphate once daily for three years is found to be effective in improving the symptoms of osteoarthritis (OA). (13)

While the exact mechanism behind the benefits of glucosamine is yet to be discovered, scientists believe that it might help maintain joint health by stimulating the production of macromolecules in cartilage and blocking the effects of inflammatory substances. (14)

  • Chondroitin Sulphate

Chondroitin sulphate or Chondroitin Polysulphate is a naturally-occurring substance in joint cartilage. It is necessary for maintaining the resistance and elasticity of cartilage.  It is usually given in combination with glucosamine sulphate.

Chondroitin supplementation has been studied and is believed to help joints by one or more of the (15,16,17,18)

  • L-Carnitine

L-carnitine is an amino acid that is naturally found in the body. The body converts ingested L-carnitine into acetyl-L-carnitine, which prevents cartilage degradation and helps reduce pain associated with degenerative joint diseases such as osteoarthritis. (19)

It appears to work primarily by reducing the serum levels of pro-inflammatory substances. (20)

  • Methylsulfonylmethane (MSM)

Methylsulfonylmethane or dimethyl sulfone is an organosulphur compound naturally found in the body. It has antioxidant and anti-inflammatory properties.

As a supplement MSM has been shown to be effective in relieving joint pain and improving the functions of the joints. Interestingly, it is thought that the benefits are increased if using MSM with collagen type II. (21,22)

The beneficial effects of MSM on joint health are believed to be due to its powerful anti-inflammatory property. In addition, it might also decrease cartilage degeneration in the joints. (23,24)
