The benefits of Green Lipped Mussels

Green lipped mussels (perna canaliculus) grow to be the largest mussels in the world thanks to the perfect conditions in which they are grown. As a result, each mussel is packed full of beneficial omega 3 fatty acids, glycoproteins and amino acids. Green lipped mussels are only grown in the clear unspoiled waters off the New Zealand coast, where the pure and organic water conditions make the nutritional content of the mussels so unique.

Popular and effective joint aid

Findings from clinical trials suggest that greenshell mussel powder extract may offer some relief from common joint conditions, particularly those that are age-related. The omega 3’s, glycoproteins and amino acids combine to maintain and repair cartilage. These findings have been published in leading medical journals around the world and show real promise for the use of green lipped mussel extracts as an effective joint aid.

World-leading Green Lipped Mussel powder  

GreenShell™ are the world-leaders in aquaculture and use an effective snap-freeze technique to capture the full nutritional content of the mussels. Their stringent environmental monitoring programmes and product testing techniques ensure that each extract consistently meets the highest quality standards. GreenShell™ Mussels are nurtured using popular environmental schemes that help to ensure sustainability for the future.

    joint relief for a spaniel 
    Deborah Shearer, Cupar
    I use this as my spaniel can't take cod liver oil. This is a great substitute, one capsule in her dinner along with glucosamine and apple cider vinegar tablets for the pain and she is doing great.

    Pain relief for bull mastiff 
    Sarah Green, Wingate
    My bullmastiff dog was diagnosed with severe disc issues in her neck, and arthritis all along her spine. I added these at 3 x 500mg a day to her current concoction of MSM, glucosomine, chondroitin and cod liver oil and there has been a huge improvement. All supplements purchased from Simply Supplements as I found them to be the best value and quality.

    Shoulder pain incl. movement limitation follwing Road Traffic Accident 
    Philippe Turner-Loisel, Nottingham
    Following a serious RTA in 1998, I developed serious pain in both shoulders and restricted movement. I have had injection of cortisone in both shoulders which reduced the pain somehow but this came back albeit not so painful within weeks. My osteopath recommended green lip mussel tablets and within a few days after taking them, the pain just went. I have tried twice to stop taking them and twice the pain came back within days. Highly recommended. Simply Supplements is the cheapest and also the most convenient.

    Me and my wife had long been suffering from poor joint flexibility so we turned to supplements and after trial and error with a few other products we eventually settled on taking the green lipped mussel (now green shell mussel) and we both feel much better for taking it.

    I purchased green lipped muscle powder. this is used by my husband with very good effect on his joints.  also my dog who has hip displasia and if he doesn't get his daily dose within 2 days is limping and finds it difficult to lie and rise. this product is provided promptly every time i order and i have found the cost to the best as other companies profess to be cheaper but then send a much lower strength. thank you for your product

    We darent risk her not taking it, now she is pain free! 
    graham dickinson, Westbury
    Our favourite supplement is Green Lipped Mussel tablets. We give our aging dog who has spondylosis (not sure of spelling). She used to "ouch" going up stairs, the vets prescribed Metacam which helped for a while. Since we have used Glucosamine and Chondroitin, but she gets a GLM tablet regularly and this seems to keep her pain free. Put it another way, we daren't risk her not taking it.

    Steve, Wickford, Essex
    I suffer from osteo-arthritis and around 6 months ago my right middle finger had stiffened to such a degree that I had considered giving up work. My finger now has full movement and considerably less pain. I also take Glucosamine Sulphate so this may be a combination effect but either way I am delighted.

    Q: With regards to your GreenShell™ Mussel Extract Powder 500mg in directions under ingredients it says for adults take one to three capsules daily, preferably separate to food, last thing at night. Does this mean taking all required capsules in one go, last thing at night?
    A: If you choose to take 1 capsule per day, we recommend that you take it after your evening meal. This is because this product is thought to support the healing process that takes place during sleep. However, if you take two or three capsules per day, it is advised to spread these out over the course of the day for optimum relief.
