I have researched over 30 brain-boosting products and I have found these 30 products to be helpful and effective for many people: 1. L-Tyrosine (Tyrosine)
This is an amino acid which helps boost your brain power, helps you sleep, strengthens the brain cells, and helps you learn faster. This product is sold in supplement form on Amazon, and it is not too expensive. Buy 2-3 servings daily and use a multi-vitamin. 2. L-Glutamine (Glutamine)
This amino acid helps your body produce more energy, and it helps fight depression. The best way to use this supplement is by taking it after a strenuous workout, in the morning, or by getting in a good workout. It is also a good source of protein and vitamin C. L-Glutamine is also helpful for those of you who are lactose intolerant, since it helps to lower your blood sugar. 3. Omega-3 Fatty Acids (Omega-3's)
A good source of fatty acids, omega-3's are vital to your body. They are good for your bones, heart, and immune system. Take a good omega-3 supplement and make sure to take it with a good multivitamin, because your omega-3's should be at least 100% as good as any vitamin A or beta-carotene. 4. Vitamin D
Vitamin D deficiency has been known to cause various mental disorders, so taking a daily multivitamin containing vitamin D in it is definitely a good idea. Dosing of vitamin D in the proper amount can also increase your body's ability to repair damage from aging.
