Can you improve your memory? Sharpen your focus? With the right diet and supplements, there's no reason you can't.

More than ever, people are understanding the connection between a healthy diet and improved brain health. Consumers are projected to spend more than $5 billion a year on brain health supplements.

Brain supplements are also known as nootropics. While first used to refer to particular chemicals, nootropics are now considered any substance - whether natural or synthetic - that may have a positive impact on cognitive abilities.

Natural nootropics can offer a multitude of benefits to enhance brain function in healthy people. While the overall positive effects are still being discovered, nootropic supplements can boost memory, enhance creativity, and optimize general brain function. When combined with a healthy lifestyle, nootropics may also reduce cognitive decline.

Brain supplements are not a "fix-all" solution via a pill. Rather, they are a useful addition to an already sufficient diet that can boost your memory and enhance your cognitive clarity. In order to reap the full benefits of these nootropic supplements, you must also keep up a healthy lifestyle. That includes ensuring regular sleep, limiting alcohol and sugar, exercising regularly, and maintaining a diet rich in dark, leafy greens and healthy oils from nuts, seeds, olive oil, and fatty cold-water fish.

With such an oversaturated market, it can be hard to find clean brain supplements. Steer clear from the hundreds of pills out there with the ingredients you don't want by choosing the best cognitive supplements to boost brain health below!

The B vitamins are particularly essential to overall cognitive health, including B6, B12, and B9. A natural amino acid, L-Theanine, also plays an essential role for cognitive clarity. Additionally, vitamin E may prove to hold value; this antioxidant fights brain-damaging free radicals.

Besides vitamins, there are a host of other supplements that may boost brain health. Omega-3 fatty acids are healthy fats that are integral for many body functions, and may have cognitive benefits as well.
