When you think of gelatin does a certain brightly coloured, jiggly dessert immediately spring to mind? If so, it’s probably the last thing you’d associate with a supplement you take for your health, such as omega-3 fish oil.

If your collection of vitamins and dietary supplements is starting to rival the shelves at your local health food shop, you may be wondering how all these active ingredients are interacting with each other in your body. Could some of the supplements you’re taking cancel out the effects of the others?

Is there something a bit, well, fishy about your fish oil? Perhaps your supplement leaves an unpleasant taste in your mouth, has a strong smell or is giving you so many fishy burps people are starting to avoid you.
