Unique Omega 3 Fatty Acid - ETA

The Green Lipped Mussel possesses a profile of Omega-3 essential fatty acids which is unique . No other marine or vegetable sources contain anything like as much beneficial Omega 3 oils. Most sources of Poly-unsaturated fatty acids (eg fish oils, flax oil etc) are a mixture of  Omega 3 and Omega 6 oils. The balance between the amount of Omega 3 and 6 consumed is vital because Omega 6 oils can increase inflammation. Our Flex  Green Lipped Mussel extract is rich in Omega 3 oils providing up to 200 times as much per milligram as fish and vegetable oils.

What’s in Green Lipped Mussel that helps dogs?

Natural Glucosamine and Chondroitin

Flex Jointcare provides a rich source of all major classes of Glycosaminoglycans (GAGS) which are principle components of cartilage and the synovial fluid found in the joint. These GAGS provide flexibility, elasticity and tensile strength to the articular cartilage.

Good joint health can depend on promoting  GAGS content within the joint and surrounding cartilage. As a source of GAGS, Green Lipped Mussel can provide chondrocytes with Chondroitin Sulphate and essential fatty acids which are critical for maintaining joint health.

A  complete joint care formula

Flex Jointcare is the complete joint-care product as it is well balanced with Chondroitin Sulphates 4 and 6, chelated minerals, Glycosaminoglycan GAGS, amino acids and essential fatty acids which together give a synergistic effect that promotes healthy cartilage and provides shock absorbing properties to the joint.

What’s the evidence that it works

Eighty-one (81) dogs suffering from mild to severe joint disease were supplemented for 112 days (between June 1997 and October 1998) either with New Zealand green-lipped mussel extract or placebo in a clinical trial at the Institute of Veterinary, Animal and Biomedical Sciences (IVABS) at Massey University, Palmerston University North, New Zealand.

The study was designed in two parts. The first 56 days were double-blinded study, where both the owners of the dogs and the veterinary clinical investors undertaking the clinical assessment were blinded to the treatment with the mussel extract or the placebo.

In the second part of the trial all dogs were placed on mussel extract from 56 to 112 days.

An assessment of the dogs´ condition (lameness, weight bearing, joint mobility, willingness to hold up contralateral limb and pain) was made by the owners as well as the veterinaries, and in addition several biochemical and haematological measurements, relevant to arthritis and other chronic degenerative joint disease were made.


The overall result of the study was that New Zealand green-lipped mussel extract supplementation improves joint disorders in dogs in an average of 74 per cent.

Until day 28 of supplementation, in both groups (mussel extract and placebo), an improvement in about 40 per cent of the dogs was observed both by owners and veterinary clinicians.

This is explained partly by natural healing and partly the placebo effect. In the placebo group, however, no further improvement was noted after this point of time, whereas in the mussel extract group the percentage of the dogs improving increased until 74 percent. When the dogs which had been on placebo until day 56, were put on mussel extract supplementation, the percentage of healing increased to an average of 91 per cent. The degree of agreement between the owners and the clinicians on improvement of the clinical condition of the dogs was very good, and suggested that, in general, treatment of arthritic disorders in pets may be determined as being successful or unsuccessful on the basis of owner observations.

This study confirms the results obtained earlier in a multicenter study conducted by veterinary clinics in Japan, where 90 per cent of dogs and cats suffering from arthritis improved when supplemented with New Zealand green lipped mussel extract.

Natural ingredients are more easily absorbed

The natural polysaccharides glucosamine and chondroitin, the 'building blocks' of joint tissue in Green Lipped Mussel, are far more effectively assimilated than manufactured glucosamine and chondroitin.

Flex Jointcare in both tablet and sprinkle form provides two additional anti-oxidant packs :-Selenium /Vitamin E and Zinc/Vitamin C. These are both synergistic combinations that have been scientifically linked to joint health.

Flex contains Selenium (in the form of selenium yeast which is more easily absorbed) and Vitamin E: both are anti-oxidants that have been scientifically associated with helping to maintain healthy joints.  Selenium, in particular, is potentially deficient in cereal based dog foods because of the low levels of Selenium in European soils.




Why do Vets  recommend Green Lipped Mussel extract for dogs?

Veterinary surgeons often now promote the addition to the diet of green-lipped mussel as a means  of long-term maintenance of joint health.

The reason ?

Because Green-Lipped Mussel is increasingly being recognised as the number one natural maintenance for joint health. It provides long term nourishment, joint and cartilage function is supported and the production of synovial joint fluid for lubrication is encouraged.

For hundreds of years the coastal Maoris of New Zealand have eaten Green Lipped Mussels as a major part of their diet. The Maoris would harvest the mussels growing naturally on the seashores and would eat them raw. Even though they saw the mussel as an important part of their diet, they did not realise the benefits they were gaining, until settlers in New Zealand later realised that these Maoris had far superior joint health compared to Westerners.

How do you know if your dog is a likely candidate for joint supplementation and could use green lipped mussel extract for dogs?

Perhaps you have simply noticed for yourself an uncharacteristic lack of enthusiasm for exercise, stiffness after rest, awkwardness mounting steps or jumping into the car.  

It really makes no difference if your aspirations were to shine in the breed ring, at obedience or agility or simply to enjoy a naturally active life-style with your pet - no doubt you will be looking around for the best way to keep him as comfortable as possible for as long as possible.

Have you pinned all your hopes and dreams, invested time and money in your choice of dog only to be told by the vet that he needs invasive joint surgery followed by short term relief to help in the recovery process or, worst case scenario, will suffer joint problems for the rest of their life?  

Remember though that dogs  do still need exercise, not so much as to cause an excess amount of wear and tear but sufficient to keep muscles toned so that they can work to support the joints.

Dogs are a species whom we increasingly realise may need additional nutrients to maintain optimum joint and limb health; larger breeds even more so.

The increasing use of dogs in sport and leisure activities such as Agility, Flyball, Cannicross, Dog Sledding and  Field Sports is another factor that increases long term wear and tear on the joints.

How Much Flex Green Lipped Mussel should I Feed To My Dog?

Flex Sprinkle is a concentrated granule that is fed with your dog’s normal food.

Each pot of Sprinkle contains a scoop that will measure 1300mg of granules, or if you prefer you can use a level small teaspoon instead of the measure, the amount isn’t too critical. There are 38 scoops in the 50 gm pot and 192 scoops in the 250gm tub

Flex Sprinkle is highly concentrated, with absolutely no un-necessary fillers, so the amount you use is quite small. Simply sprinkle the amount required onto your dog’s food once or twice a day. Giving the Sprinkle with food ensures maximum digestion and benefit. While the flavour of Flex Sprinkle is fairly neutral and most dogs won’t notice visually that it’s there, they will easily detect its aroma of the sea. Generally they wolf it up! Some owners, though only a few, find it helps to slightly moisten dry food to prevent Sprinkles being left at the bottom of the bowl.
