Here is the Relief Factor ingredients list along with dosages and a brief explanation of what the ingredients do (or don’t do) for joint pain:

• Omega 3 900mg: Omega 3 is an excellent anti-inflammatory agent. The Relief Factor supplement contains docosahexaenoic and eicosapentaenoic acids (DHA), which are both omega 3 fatty acid. These powerful acids have been shown to reduce inflammation genes in the body, according to studies.
• Turmeric 667mg: This herbal medicine is well-known for its anti-inflammatory and antioxidant properties. A study has shown that curcuminoids (a component of turmeric) are more effective than medications in relieving arthritis pain.
• Epimedium 200mg: Epimedium, a Chinese herb, has been used for centuries in order to relieve inflammation-related pain. Epimedium herb contains Icariin, an active compound that can be used to relieve pain from arthritis. One study found that it has been shown in one of its studies.
• Japanese Fleeceflower 70mg: Resveratrol, a compound in Japanese Fleece Flower, promotes blood circulation and can reduce inflammation. This ingredient is believed to support and protect joints, and may have neuropathic pain relief effects.

As you can see, there is nothing revolutionary or particularly exciting about the Relief Factor ingredients list. This is probably why the Relief Factor website doesn’t give us much information on the ingredients; all we get is a short paragraph on the homepage. 

Overall, we are not impressed with Relief Factor’s ingredients. Epimedium has never been shown to effectively reduce joint pain in human clinical trials. Resveratrol might be a powerful antioxidant, and it may help protect joints over the long-term. But again, it has never been shown to be effective for joint pain in independent clinical trials

IMHO: just another ripoff of uninformed people who are niave or too lazy to do the research before parting with their money.

You can buy these ingredients over the counter - cheap!
