Arthri-D has a great number of ingredients including Vitamin D, Turmeric, N-Acetyl Glucosamine, Boswellia, Yucca, Ashwagandha and some others. The manufacturer claims that this blend of minerals, vitamins, and natural extracts can treat joint inflammation and pain. However, there is no scientific proof of this fact. The substance N-Acetyl Glucosamine is claimed to allowing the human body to work in combination with Vitamin D. These help to repair the damaged cartilage around the joint, strengthening it and protecting from future degeneration.
Turmeric is a powerful antioxidant, while Boswellia is used to improve joint health another ingredient in the supplement, Green Lipped Mussel, is said to be rich in fatty acids which are responsible for lubrication of the joints. Hyaluronic Acid hydrates the joints and reduces friction between the joints. The full list of ingredients in Arthri-D includes Vitamin C, Vitamin D3, Magnesium, Chondroitin sulfate, N-Acetyl-D-Glucosamine (NAG), Tumeric Extract, Boswellia Serrata, Rice Flour, Ashwaganda, Bromelain, Yucca (root), Perna Canaliculus (Green Lipped Mussel), Evening Primrose oil, and Hyaluronic Acid (Sodium Hyaluronate).
I am concerned about the absence of any published materials telling about the effectiveness of the main ingredients as well as about arthritis research. The official website of the supplement shows no studies on the components of the product. The National Library of Medicine for "Arthri D" also has no studies. It can be concluded that Arthri D has no good proof that it fights arthritis.
Arthri D contains vitamin C and D and magnesium, however the amounts of these nutrients in the supplement are so miserable that they can hardly have any significant effect on your joints.
The amount of N-Acetyl Glucosamine in Arthri D3 is unknown. It is only stated that the "proprietary blend" contained in the product is 1027 mg (about 1 gram). I can only assume the major component of the blend is N-acetyl Glucosamine. As a matter of fact, few arthritis supplements contain this kind of glucosamine. No studies have been conducted on this kind of Glucosamine (NAG).
Chondroitin sulfate can be often found in arthritis supplements, but its effectiveness is under the question too. Some studies showed that this component might improve the state of knee osteoarthritis. Still, other studies have demonstrated that chrondroitin sulfate has nothing to do with arthritis symptoms. There are studies that showed effectiveness of chondroitin only when combined with certain exercise.
Tumeric is also called Curcuma longa and curcumin. It is known for its anti-inflammatory properties. The supplement also contains Rice Flour but I failed to find any arthritis research on this ingredient. Boswellia Serrata is another anti-inflammatory compound that has very contradictory studies. Ashwaganda has no specific evidence of its ability to reduce arthritis pain and to protect cartilage cells. Yucca is said to have some anti-inflammatory properties, but there is no proof of its effectiveness for the treatment of arthritis in people.
Bromelain is an enzyme contained in pineapples. It's known for its anti-inflammatory properties but few scientists confirm its effectiveness for arthritis. One study showed that bromelain didn't reduce arthritis pain. Evening Primrose Oil is an example of an omega 6 fatty acid but it lacks a good human arthritis research. Hyaluronic Acid can be found in some arthritis products but the main bulk of the research is connected with injecting it into joints, not taking it orally. Perna Canaliculus is an extract from a mollusk and is known for some anti-inflammatory properties. It is unknown whether this compound can help arthritis.
