I've been living in Australia for a while and over there I bought supplements from Nature's Own. Their fish oil information reads:
Omega 3 is important for the maintenance of general health and wellbeing, as well as for heart, brain and joint health. For joint health: Take 5 capsules daily with food
Each capsule contains: 2000mg (2g) Equiv. Omega-3 Marine Triglycerides 600mg Equiv. Eicosapentaenoic acid (EPA) 360mg Equiv. Docosahexaenoic acid (DHA) 240mg
That makes 10 grams of fish oil daily, eq 1800 mg EPA, 1200 DHA.
Now, I'm back in Europe and I cannot find any brand claiming joint benefits, in the stores nor on the internet. What's more - the 10 g fish oil recommendations seems to be over the top that may lead to bleedings. For instance, the recommended dose EPA+DHA seems to be up to 2 g max.
In short: Does fish oil support normal joint health (not restricted to inflammatory diseases such as rheumatoid arthritis) and if yes, in what dose? *
* I am aware that fish oil may reduce the symptoms of arthritis and other inflammatory diseases. However, I'm relating to regular joint health, for example to support joints during periods (months) of intense physical exercise
