When it comes to brain-boosting power, there is no substitute for a good diet, improved sleep, exercise, and living a life of balance, but some supplements can provide a big boost to your brainpower and offer other, longer-term health and cognitive benefits. Here’s our team NSO list of top supplements for boosting your brain-power:
Ketones with caffeine
The combo of ketones and caffeine is becoming a very popular ‘brain-hack’ (at Team NSO, we have all noticed massive benefits to focus and energy from this combo)
Caffeine is the king of brain-boosting supplements, and so long as you don’t overdo it, it is also a health-promoting one. Caffeine improves attention, vigilance, reaction times, and problem-solving,1, 2 and interestingly, people who use it regularly have better results than those who use caffeine irregularly3 (great for those of us who enjoy a daily cuppa Joe!)
Exogenous ketone supplements are being studied for their use as treatments for brain injury,4 and Alzheimer’s disease,5 amongst other conditions. They have positive effects on anxiety,5 mental performance and memory,5 while also helping to reduce stress and fatigue in the brain.6
Multivitamin/mineral supplements can help to ‘fill in the gaps’ in your nutrition and they have been shown to improve cognition and memory and reduce depression and anxiety.7, 8 Whole-food based multis like Good Green Stuff that includes other cognitive boosting herbs and foods are likely to perform even better.
The omega 3 fats DHA and EPA from fish oil play an important role in brain development and healthy functioning of the brain and central nervous system. DHA, in particular, is essential to the functioning of the brain and optimising cognition and mood.9
Omega-3 fats found in fish oil are linked to reduced mental fatigue,10 improved memory and cognition and reduced cognitive decline,11, 12 reduced rates of depression and improved structural integrity of the brain.13, 14
Medium-chain triglycerides (MCT) are naturally occurring fats found in small amounts in dairy products and greater amounts in coconut oil. MCT supplemented diets improve mental performance and reduce age-related cognitive decline,15, 16 and even a single dose of ~20 g MCT has been shown to improve cognition.17
Lion’s Mane Mushroom
Lion’s Mane (Hericium erinaceus) medicinal mushroom native to North America, Europe and Asia. Lion’s Mane has been shown to increase ‘Nerve Growth Factor’,18 which helps nerves and brain cells to grow and repair.19-24 Because of this brain-repair effect, Lion’s Mane is being considered as one of the most promising preventative treatments for Alzheimer’s Disease and dementia.25, 26 It’s also been demonstrated to significantly reduce depression and anxiety after 4 weeks of treatment,20 and to improve cognitive function.27 Lion’s Mane might also improve physical performance by reducing perceived fatigue.28 Note: Other mushroom types, especially Turkey Tail (Trametes versicolor), Cordyceps (Ophiocordyceps sinensis), and Reishi (Ganoderma lucidum) is also suggested as benefiting neural health and cognition.
