CLINICAL DOSING
GLC2000 makes sure the right amount of nutrients get to your joints at the right time using:
Personalised Dosing
Tailored to your bodyweight. It is well known people of different sizes require different amounts of nutrients to thrive. This is no different when it comes to effective joint supplementation. Yet every other joint supplement seems to offer a one size fits all approach. Which is never going to work for most people.
GLC2000 use extensive research and testing to devise the most effective way to deliver the right amount of nutrients for joint support based on bodyweight
24hr Nutrient Delivery
Each capsule of GLC2000 delivers a consistent supply of joint supporting nutrients for up to twelve hours. To maximise effectiveness GLC2000 recommends split servings to ensure round the clock nutrient delivery.
This mimics how your body naturally delivers nutrients. So your joints have high quality building blocks exactly when they need them

Thousands of customers report that GLC2000 works for them when other products have had no benefit. Here's how:
Increased Individual Response - People respond differently to various glucosamines. By including all four GLC2000 has the type that works best for your specific needs and tolerability
Diverse Mechanisms of action - Different forms of glucosamine have different mechanisms of actions and absorption rates in the body. To help address various aspects of joint health
Synergistic Effect - Enhances the combined effects beyond what each nutrient could achieve on it’s own
Comprehensive Joint Support - Glucosamine is an essential building block of cartilage and other connective tissues. All four forms means your body has a wider range of resources to maintain and support joint function

Real People Real Results

Moving Without Fear Anymore!
I’m TERRIFIED of getting arthritis. And want to make sure it’s not going to happen to me! It runs in my family and I’ve seen it sap the joy out of both my grandparents and parents. So I’ve always kept fit – but that comes with added wear and tear to your joints. I’ve always used a joint supplement but was never sure if it was actually working. I’d still get stiff, sore joints. And felt I was on the verge of an injury that could be the beginning of the end.
Since using GLC2000 – I can really feel the difference. I’m moving well and I don’t feel like an old creaking door anymore. I’m enjoying training. And not worried about my joints anymore.

It’s A Night & Day Difference In My Knees
If squats were on the whiteboard as I walked into the gym I’d want to turn around and walk straight back out. Not anymore!
Squats, running, box jumps, lunges will never be my favourites. But I can actually do them now. And I’m stronger and fitter than I’ve been since my 20’s. The difference?
GLC2000 – a joint supplement that’s really popular in my over 40’s Crossfit class. I was always questioned how fit, strong and flexible all these people in their 40s, 50s & 60s were. Well GLC2000 was the answer.

Nothing Was Helping Until I Tried GLC2000
I try and go to Crossfit at least 3 times a week. After almost a year of training it was getting harder to recover between sessions. My shoulders were always sore – not the muscles, but in the actual joints felt stiff. I couldn’t get comfortable at night. And even simple things like putting my arms above my head hurt. My coach helped me with stretching and other exercises and when those weren’t working he recommended GLC2000 to me.
It wasn’t long before my shoulders were feeling good again. Within a few weeks I’d say. I’m at the gym 3 times a week again (sometimes 4!) And look forward to going again.

I’ve been on GLC 2000 for 10 days and have noticed a huge change in the level of pain in my knees. Definitely life changing for the better so I highly recommend the product. Thank you

This product was highly recommended to me by a friend, so I decided to give them a try as I was suffering with aching joints in various parts of my body.
My knees and shoulders had a niggling pain for awhile and whatever I tried did’nt seem to work. It was getting to the point where I was starting to worry about what winter would be like – you know how the cold makes everything worse.
I’ve nearly finished my first bottle now and I can honestly say I’m glad I gave these a go. Glad enough that I’ve just ordered a further 3 bottles to see me through. The cold months have started to arrive now, so I’m hoping this will mean a much easier Winter than I was expecting a few weeks back.
Still early days for me, but feeling more optimistic than I have in a while about my joints.

I’m in my late 50s, and years of heavy lifting was taking it’s toll on my joints, especially my shoulders.
I was in pain almost constantly, and on a bad day I couldn’t press anything bigger than a 10kg dumbbell.
I tried all sorts of off the supplements and physio, but nothing changed.
I finally bit the bullet and bought some GLC2000. I was always put off by the price, but I was getting desperate.
At 91kg my recommend dose was 4 caps a day. I starting taking 2 capsules with my breakfast, and 2 with my evening meal.
Now I’m not sure if it was a coincidence, but a week in my asthma flared up. I read that this was a potential side effect of glucosamine supplementation.
At 2 weeks I noticed that my shoulder wasn’t as sore as usual. By week 3 I was sleeping much better, and my shoulder pain was almost gone.
One month in and my asthma settled down. I’ve not used my inhaler since. My shoulder pain has gone for the most part. Still the occasional niggle after a heavy gym session, buy I can live with that as I’m now back to lifting heavy again!
I was always very sceptical about products advertised through social media, but I have to admit that GLC2000 is one of the good guys, and cost vs return I can happily say it’s worth every penny.
I’m about 6 months in now. Still not used the inhaler, and my lifts are greatly improving on what they were prior to taking GLC2000.

I’ve been using this product consistently now for around a year or so and I can’t tell you enough the difference it makes in my life. I’m 51 years old training pretty hard still, I skateboard as well and the difference in my range of movement in my knee through not being in pain all the time especially at end range is a game changer. I will always have this as part of my daily routine.

I have been using this supplement for the past few months. Being now 56yrs old, and playing football until I was 44yrs old, my knees in particular are somewhat ‘well used’ and can be quite painful at times. GLC2000 has definitely made a difference to me. I now train 4-5 times a week without the same level of discomfort, and do not need knee sleeves for every session. I am even back to running without the pain I used to have. Hence I have placed my next order. Thank you.

I am 67 years old. I currently do 2 aerobic and 3 weight training classes each week. After 7 knee operations (on both knees, mainly meniscus) I was told 11 years ago that the only solution for my knee pain was a new knee. Instead I worked on building quads, hamstrings and calfs, and not sitting as much. Pain subsided a lot but still an element of stiffness. Took these pills and within 2 weeks I noticed an improvement and 2 months later the stiffness was 90% gone. Went on a 4 hour plane trip last month and remarked to my wife how I was able to stand up without any stiffness in my knee at the end of the flight. Gave my body a rest from all supplements except turmeric during the holiday and on the plane journey home I had great difficulty standing up at the end of the flight and the knee felt quite stiff. Within a week of commencing taking them again all was fine. I think that shows that they work but not on a cumulative basis. I think they work for a short time and need to be taken regularly. I know I have damage in my knees but these pills help me do what I love although I still have to manage my condition by avoiding anything that causes pain – but I’m not a youngster any more!

Wooow what can I say apart from this is by far the best joint supplement I have ever come across, I have been suffering with joint pain more so in my knees, I struggled with squatting and any exercises that required heavy loads and would take days if not weeks to recover, I have been taking glc 2000 for less than 2 weeks and have noticed a huge difference no more achy joints no more cracks, pops and sharp pains in my knees.
Thank you for the best joint supplement on the market

It was initially 2-3 weeks when I really started to notice the difference for me. I was due to have a hip replacement and was really limping, not able to do many exercises and having to take pain killers. Now over a year on, I still hobble a little, have no pain killers, can do everything apart from run and haven’t had a hip replacement! I’d tried others before but these were the game changer for me!

Running has always been my freedom – until my knees started giving out after just 6 miles. The pain would creep in, sharp and persistent, forcing me to cut my runs short. Watching that limit shrink was more than frustrating; it was depressing.
I decided to try GLC2000, taking 2 tablets morning and evening based on my weight. The first two weeks? Nothing. I nearly gave up.
Then around week three, something changed. The pain that used to kick in at mile 6 simply didn’t show up. I kept running. Mile 7, mile 8, no pain.
Now I comfortably run 10 miles twice a week, and I’m training for the Athens marathon in November. At 66 years old, GLC2000 gave me back what I thought I’d lost – my freedom to run.

With a torn meniscus and severe arthritis I had struggled for a year and despite physio etc was hardly walking as in extreme pain. I had to use walking poles to get around. Having seen this advertised I decided to give it a go and was amazed. Within a few weeks the pain was less and I managed to start walking longer distances and without the poles!
I have now ordered my second pot and have already told so many people about this supplement, including my physio who could see a vast improvement over rhe last 2 months!
I would definitely recommend this product!

Having been an avid runner for many years, I experienced a medial meniscus tear in my knee, and after a year of waiting, I underwent surgery. The demanding rehabilitation process of physiotherapy and gym work commenced, but even a year post-operation, I continued to experience some discomfort, particularly after running, necessitating ample rest before subsequent runs.
This is where social media played a role, and I discovered GLC 2000 earlier this year. I decided to try it, considering I was willing to explore various options, especially since I had contemplated pain injections in my knee before learning about these.
Initially, after taking two tablets in the morning and two in the afternoon, I felt no noticeable effects. However, after approximately 7 or 8 weeks, my pain completely subsided, allowing me to enjoy running once more. While I haven’t fully regained my previous level of fitness, I am now running without pain and have reduced my daily intake to two tablets.
I am hoping that in the coming months, I will be able to return to my usual running times perhaps even chase some PBs 😁

I considered these for a long time before buying thinking “ oh there a bit more expensive etc” then I thought to myself I don’t think twice about the joint supplement I purchase for my horse which is more expensive. I had 2 knee replacements 2024 and recovery was great back up to speed now with all CrossFit etc and started running. I’m nearly 60 and my knees though so much better would get stiff and be uncomfortable so I thought I would treat myself. I’m so glad I did. I do believe these are making such a difference. Quicker recovery after workouts and general 💯 improvement. Highly recommend

I’m due to reorder and notice that my achey knees are back when I’m not on GLC 2000. This has oiled my joints like no other supplement could. I’m confident in my knees and this is reflected in my exercise regime running and lifting. I’ve tried lots of supplements for joints but this really does works.

I tried GLC2000 because I couldn’t run on the road for more than 5 minutes. The pain in my knees was unbearable so I started to take GLC2000. I noticed a difference initially after about a month of taking it. My knees didn’t hurt when climbing the stairs. And now after 6 months I am running 5kms 3 times a week with no issues at all. The difference is amazing. I honestly thought my running days were over. It’s a game changer.

I was very sceptical when I first tried this joint supplement, but I have found since taking it my knees are much less painful. I did stop for a while and I have overdone it so I am now relying on glc2000 to help my knees back to being pain free. It has now started to work its magic again, so it’s a thumbs up from me! Thank you glc2000!
