IQ can definitely be affected by nutrition and supplements. That will shock a lot of people, but study after study has showed just this. And it’s not suprising: the brain consumes about 40% of the body’s energy. It is metabolic workhouse and needs a constant and abundant supply of nutrients to work optimally.
1) Multivitamins. Vitamin supplements given to teens aged 13-16 raised non-verbal IQ scores by an average of 6 points. However, it should be noted that several teens actually improved IQ by over 20 points indicating that nutritional deficiences may have been holding back mental performance. An additional part of the study of the same general age group again showed astonishing results: half of the students increased non-verbal IQ by an amazing 15 points! (here is a whole food multivitamin designed for kids)
2) B Vitamins and Vitamin C. One study showed a 25% improvement in scores in many categories of cognition and memory among those students with the highest levels of B vitamins and vitamin C as opposed to those with the lowest.
3) Choline. Choline has produced near miraculous results in animals studies. For example, pregnant rats receiving extra choline produced obviously superior offspring in terms of intelligence and memory. The researchers wrote that “when rat pups received choline supplements (in utero or during the second week of life), their brain function changed, resulting in the lifelong memory enhancement.” Other studies have shown that choline supplementation forms extra dendrites, i.e nerve cell connections. The reason? Choline is a precursor for actylcholine, the memory-building neurotransmitter.
4) DHA. EPA and DHA are the two key omega-3 fatty acids in fish and fish oil, and DHA has now been shown in a study to increase the cognitive development of infants.
5) Exercise. Evidence mounts almost monthly that exercise increases IQ, intelligence, cognition, learning and so on. One recent monster study of 1,000,000 Swedish military males verified previous studies and showed that exercise increases brain power in many ways.
