N-acetyl glucosamine benefits knee function
We explored the effects of N-acetyl glucosamine and chondroitin sulfate supplements on knee pain in Japanese adults aged 52 to 87 over 24 weeks. Participants were divided into two groups, one receiving the active supplements and the other a placebo. The results showed a positive impact on knee function and daily physical activity, indicating that longer-term use of these supplements can be beneficial for easing knee pain and improving mobility in older adults.
However, it's important to note that some previous studies have not found such satisfying results about glucosamine and chondroitin effectiveness.

We aimed to see how an N-acetyl glucosamine and proteoglycan supplement affects knee pain and movement in middle-aged and elderly individuals. In an open trial with 19 participants, we found that after 12 weeks of taking the supplement, knee pain significantly decreased. Evaluations showed improvements in daily functions, like walking and stair climbing, clearly noticeable by the 8th week. Overall, we observed that this treatment offers promising relief and enhanced knee function for those struggling with pain.

Knee crunch resolved
10 people found this helpful
My knee was very crunchy after an injury. I initially took only glucosamine and chondroitin; they did not help. Once I added N-A-G, I finally walked without a crunch in my knee! Those who haven't experienced knee pain will not understand the happiness it brings. The various sources mention the benefits for mucous membranes, but I mainly noticed relief in my knee discomfort.

I found Jarrow Formulas' N-A-G to be incredibly beneficial for my joint health. The 700 mg dosage has improved my comfort and mobility, especially during activities stressing my knees. The veggie capsules are easy to swallow, made with quality ingredients, and have become a staple in my routine, allowing me to remain active and feel my best.

My knees feel significantly better since I started taking two pills a day. Initially, there was a crackling sound and a stinging sensation, but it improved quickly. Great effect!

Knee pain relief

I really like this supplement. I take it in the morning on an empty stomach, mixed with pilium and glutamine for a course of 2-3 months. I started taking it to restore my gastrointestinal mucosa, but I also found that it helped with my knee pain. The crunching stopped, which made me very happy. The cost is affordable, sufficient for two courses in two months, lasting over half a year. I recommend it to everyone!

Quick knee relief
2 people found this helpful
I purchased this for my knee along with another product, which I couldn't continue due to stomach issues. This NAG is fantastic; it works surprisingly quickly. After falling a few days ago and spraining my opposite ankle, I felt grateful to have been taking this already, knowing it would help my ankle heal faster. I remember taking this product years ago for a stomach issue, and it worked then too, which is why I decided to buy it for my knee and now my ankle.
