Studies have shown that krill oil may benefit some high-school-age teens, but these studies are not completely reliable, reports NYU Langone Medical Center. The omega-3 fatty acids in Mega Red krill oil have been shown to treat high cholesterol and ADHD, and also ease menstrual cramping.
Studies have indicated that increasing the level of omega-3 fatty acids in children reduces the severity of ADHD, according to The Royal Children's Hospital Melbourne. However, other research shows no improvement in ADHD symptoms after consumption of omega-3 fatty acids, so more studies need to be conducted to determine if krill oil helps with ADHD, as of 2015.
The main danger associated with Mega Red krill oil is blood thinning, reports NYU Langone Medical Center. Other side effects include stomach upset and allergic reactions. Teenagers are advised not to take Mega Red krill oil if they have a seafood allergy, a bleeding disorder or are taking blood-thinning medications, reports The Royal Children's Hospital Melbourne.
Mega Red krill oil is a brand of krill oil derived from tiny crustaceans in Antarctica, according to Mega Red. It is higher in omega-3 fatty acids than fish oil, so the dosage is less, according to Drugs.com. In addition, fewer users report experiencing a fishy aftertaste after taking Mega Red krill oil. Mega Red krill oil is most often used to treat issues associated with older adults, such as heart disease, high cholesterol and rheumatoid arthritis, reports WebMD.
