When I work with athletes on basically any aspect of sports nutrition, one thing I find that constantly need to remind them of is: if some is good... MORE is not better. This relates to supplements, water, omega-3 fats, probiotics, protein, etc.
I had an athlete once that started experiencing nose bleeds and bruising easily for no explained reason. After talking with them, I realized they were taking an omega-3 supplement daily, having fatty fish like salmon most everyday (rich in omega-3 fats), have omega-3 eggs, and routinely adding fish oil to smoothies. So while omega-3 fats have potential benefits in decreasing inflammation, they also can result in disturbances in blood clotting. Once this athlete backed down on the omega-3 intake, the nose bleeds and bruising easily issues cleared up.
I had another athlete that was cramping up so bad during games that they couldn't finish a game. After reviewing their game day routine, it was determined that they were over hydrating to the point where important electrolytes (e.g. sodium) were being flushed from the body and resulting in cramping. Once their fluid intake was adjusted, the cramping issue subsided. See the Hydration 101 handout and Game Day 3-page handout for more tips and recommendations.
IF SOME IS GOOD... MORE IS NOT BETTER
When it comes to any aspect of sports nutrition - products, supplements, water, etc. stick with the recommendations and work with your doctor and a sports dietitian on a custom plan that is right for you. Never assume that if some of something like omega-3's or water is good, then more will be better.
