Fish oil will purportedly help with inflammation, but the problem lies in finding out how much is enough.
More is not necessarily better. If you are injured, and it sounds like you are, your best friend is RICE, or Rest, Ice, Compression, Elevation. Anti-inflammatory medication is sometimes included.
To reduce inflammation, I see no wrong in reading the instructions on the package containing the fish oil. Your body goes through three phases of healing. They are:
- The Inflammation Phase
- The Repair Phase
- The Remodeling Phase
Your goal regarding these phases are to go through them as fast as possible. As long as you're in pain, it's safe to say you're staying in the inflammation phase.
Tendinitis is indicative of overuse. Take it easy-continuing exercise is important, but you risk greater injury given working with the injury. If you were my client, knee flexion and extension would likely be off limits unless it was low impact, like cycling.
Dietary recommendations are outside my scope of practice, and not enough information is given for me to feel comfortable doing so. You desire to be rid of inflammation, so in that respect I believe RICE is appropriate.
The median intake of DHA is between 1.2 to 1.6g/d for an adult male. No upper intake limit has been established, as there is no evidence stating someone's ever taken too much of it.
I got that from the National Agricultural Library: Page 478, last paragraph, USDA report on DRI
