Fantastic liquid supplement

I have been taking Cartonica liquid regularly for a few months and I've found it a delicious and easy way to digest a wide variety of quality nutrients

Cartonica is one of the leading all-round supplements for healthy joints.

A high strength liquid blend of Glucosamine Sulphate and Chondroitin Sulphate with the added benefits of Collagen and more.

Using a liquid, nutritional ingredients are dissolved to create a complex blend.  This means that Cartonica contains far more nutrients in a single serving than any tablet joint supplements.

  • Collagen Type II
  • Glucosamine, Chondroitin, MSM
  • L-Carnitine & Turmeric
  • Vit D, B12 and C

It can be very confusing knowing which nutrients or products to choose for your joints.  Cartonica was originally formulated from insights in sports science where nutrients for performance are dissolved in a liquid.

By dissolving key nutrients to support joint health in a liquid, Cartonica gave clinicians a product which delivered a wider blend of nutrients in greater quantities than tablets, with the added benefit of superior absorption by the body compared to dry tablets.

Additionally, the human body uses nutrients synergistically.  That is, the body needs to use a variety of nutrients at the same time in order to have the building blocks for our cells.

With ten nutrients in one place, Cartonica thus provides the body with the mix of nutrients it needs, all at once.


These key benefits of Cartonica also served the patients of clinicians in another way.  It did away with the need for patients to take a lot of different single or dual nutrient tablet products.

Many of these tablets are low dose and typically present the consumer with the bewildering task of having to work out which one(s) to take, whilst adding up to a substantially greater cost than Cartonica for the equivalent dose.

All of the nutrients in Cartonica are fully supported by scientific references (see Ingredients & Research tab above).  So you can be assured that you are getting the right ingredients for your joints.

Beats All Tablets

Tablet joint supplements can only contain a limited quantity of ingredients as the nutrients are dry compressed, with a maximum of around 1,000mg of nutrients per tablet.

Practically all standard glucosamine sulphate, chondroitin sulphate and other joint supplements require us to take two, three or even more tablets per day.  However even then the dosage and number of nutrients in these tablets fall well short of what our body receives from Cartonica.

Cartonica has over 6,000mg of nutrients per 15ml serving.  No tablet supplements come anywhere close to this.

REHAB: If taking Cartonica alongside a rehabilitation programme such as joint stability strengthening, people can choose to take a larger 25ml serving for the first month.  This will give 10,000mg of nutrients for added nutritional support.

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.  See label for nutrient list.

Dosage guidance: We see no merit in taking more than 25ml of Cartonica per day, however for reassurance the food state nutrients in Cartonica do not pose a risk should you inadvertently take more.

A 15ml serving of Cartonica contains 120mg of Vitamin C whilst a 25ml serving contains 180mg.  If taking other Vitamin C products, it is not recommended to take more than 1,000mg of Vitamin C per day.


Many people look for joint supplements to help with arthritis pain.  Joint supplements are not intended as a cure or treatment for arthritis pain.  However many people looking to support their joints take Cartonica alongside their arthritis care plan.  If you are suffering with arthritis, seek appropriate medical advice from your doctor.

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 be 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)

  • Stabilises the joint space and modifies bone metabolism in the joints.
  • Inhibits the destruction of cartilage tissues in the joints.
  • Regulates the synthesis of hyaluronan, a substance that lubricates and cushions the joints.
  • Reduces the production of pro-inflammatory substances in the joints.
  • 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)
