Side Effects and Legal
Are there any side effects?
The greatest risk of fish oil omega-3 supplementation is heavy metal poisoning by the body’s accumulation of traces of heavy metals which may be found especially in less refined fish oil supplements.
There is also a potential risk is the possibility of vitamin poisoning from taking large doses of supplements which contain large quantities of vitamins (particularly vitamin A) in addition to omega-3 fatty acids, which is why it is better to augment the intake of these fatty acids through natural food substances which contain them as outlined above.
Are they legal substances for athletes?
As Omega fatty acids are present in natural food substances, they are not on any banned list. However it should be noted that ingestion of any high dosages of vitamin supplements should be checked first with a sports doctor familiar with IOC rulings.
