Is Chlorella Good for the Brain?
In the realm of dietary supplement products, chlorella has proven to be one of the most promising and popular among consumers.
That’s because this tiny blue-green alga is packed with essential vitamins, minerals, amino acids, essential fatty acids, protein, fiber, and other nutrients. Chlorella algae also have unique components called chlorella growth factor, which serves as one of the highest sources of chlorophyll.
Given its high nutritional value, it shouldn’t be surprising that chlorella is associated with many impressive health benefits — one of which is that chlorella helps promote brain health.
Specifically, many scientific studies have focused on how chlorella improves cognitive functions as well as potentially reduces the risk of memory loss and neurodegenerative diseases.
6 Promising Benefits of Chlorella to the Brain
According to scientific and nutrition journal articles, there are many mechanisms by which chlorella improves brain health.
Though there is still a long way to go when it comes to understanding the relationship between chlorella and brain function, what we know so far is that chlorella may be able to:
1. Help Detoxify ‘Brain-Damaging’ Heavy Metals
Heavy metals such as cadmium, mercury, and lead are neurotoxins. These environmental toxins are known to disrupt normal brain functions. This can then lead to impairments in learning, memory, attention, and other cognitive abilities.
Heavy metals may also damage the structure of brain cells and promote brain cell death over time. Consequently, researchers have found that there is a strong correlation between heavy metal exposure and neurodegenerative diseases like Alzheimer’s and Parkinson’s.
Thankfully, heavy metal detoxification is one of the excellent benefits of chlorella to the brain. With high levels of chlorophyll and metal-binding peptides, this tiny but mighty superfood can bind to heavy metals and flush them out of your system.
Studies have shown that chlorella supplementation can help lower levels of cadmium, mercury, lead, and many other heavy metal toxins. As such, chlorella may help avoid heavy metal accumulation in the brain and reduce the risk of cognitive decline.
2. Help Improve Oxygen Delivery to the Brain
Chlorella is also known to help lower blood pressure levels, increase red blood cells, improve circulation, promote arterial flexibility, and increase peak oxygen uptake.
While these may seem like benefits for heart health and athletic endurance, they also have potential health benefits for the brain. This is because the brain consumes 20% of the body’s total oxygen supply. So, by improving blood flow and oxygen levels, chlorella can help ensure that the brain receives adequate oxygen and nutrients to be able to function optimally.
In one study, maximal oxygen uptake was found to benefit both aerobic fitness and cognitive performance. Participants with higher levels of VO2 max performed better on tasks involving attention and memory.
Oxygen also helps promote synaptic plasticity in the central nervous system. According to experts, oxygen deprivation may cause brain damage and mental deterioration — which can then lead to the development of dementia. Low blood supply is also linked with increased amyloid buildup, which is one of the hallmark characteristics of Alzheimer’s disease.
As such, taking chlorella supplements may not only benefit heart health but also helps keep the brain healthy and flexible.
3. Reduce Oxidative Stress in the Brain
Since the brain consumes a lot of oxygen, it also produces a lot of free radicals — making it highly susceptible to oxidative stress. At the same time, our antioxidant capacity also tends to decrease as we age. Age-related oxidative stress due to free radicals can cause inflammation and damage to the brain, which is also why the older generation is more prone to cognitive impairment and neurodegenerative disorders.
One way to reduce free radicals and oxidative stress is to increase antioxidants in the body. As it so happens, chlorella contains a lot of antioxidants — including beta carotene, chlorophyll, lutein, vitamin C, and vitamin E. In addition, chlorella contains polysaccharides, amino acids, omega-3 fatty acids, and minerals that can help protect against oxidative stress.
Animal studies have found that chlorella’s antioxidant effects can help reduce oxidative stress and potentially deter age-related cognitive impairment.
Meanwhile, in a clinical study, senior Japanese participants with dementia were given 8 grams of chlorella daily for two months. Results showed that the chlorella group had higher plasma lutein concentrations than the placebo group.
After chlorella supplementation, they also had lower phospholipid hydroperoxide (PLOOH) in their erythrocyte membranes. High PLOOH levels are a known characteristic of neurodegeneration.
The ability to increase antioxidant levels is one of the most promising chlorella brain benefits — especially considering how damaging oxidative stress is to the brain.
4. Help Maintain a Healthy Gut-Brain Connection
The gut-brain connection has long been established. As such, there is value in also taking care of our digestive health.
Studies have found that certain issues with the gastrointestinal tract can have a significant effect on brain health. For instance, gut dysbiosis is thought to play an important role in the pathogenesis of neurodegenerative disorders.
When bacteria escape from the bloodstream, they also release toxins that trigger systemic inflammation. This leads to the release of inflammatory cytokines, which can increase the blood-brain barrier’s permeability and cause brain inflammation. Gut dysbiosis may also impact the production of neurotransmitters, which can impact cognitive functions like memory, learning, and mood.
To further illustrate the gut-brain connection, researchers have found depression and anxiety are common psychological conditions among those with gastrointestinal disorders like IBD. Given these findings, chlorella’s ability to maintain a healthy gut can also benefit our brain health.
According to studies, chlorella benefits include promoting healthy bacteria in the gut. This, in turn, can help strengthen the intestinal barrier and stop pathogens from escaping the gastrointestinal tract.
Moreover, chlorella supplements also promote regular bowel movements — ensuring that heavy metal toxins and other harmful substances are removed before causing any harm to the entire body.
5. Provide Essential Nutrients for Optimal Brain Health
As one of the best superfoods, chlorella is packed with many essential nutrients — including those needed for optimal brain health. Researchers have found that there is a relationship between certain nutrient deficiencies and the occurrence of cognitive decline.
For instance, a vitamin B12 deficiency has been linked to memory loss and cognitive impairment. It may also cause elevated homocysteine and methylmalonic acid levels, which are associated with dementia and Alzheimer’s disease among the elderly.
Deficiencies in iodine, iron, zinc, vitamin D, and other B vitamins have also been known to cause neurological or cognitive impairments and increase the risk of brain disorders.
Chlorella’s Brain-Boosting Nutrients
The good news is that chlorella supplements are rich in all those brain-boosting nutrients. Not only that, but chlorella contains many other beneficial nutrients for brain health. This includes:
- Omega-3 Fatty Acids – Contain DHA and EPA, which help strengthen neuronal connections, enhance memory and learning, and protect the brain from neurodegeneration; along with omega-6, these essential fatty acids promote normal brain growth and development
- Choline – Plays a crucial role in producing neurotransmitters that regulate memory, intelligence, and mood; Essential for brain development
- Folic Acid – Crucial for brain development in the womb; Deficiencies associated with mood and cognitive problems in older people
- Essential Amino Acids – Chlorella contains all essential amino acids, which are essential for cognitive function; May delay the onset of dementia
- Selenium – Protects neurons from oxidative stress and damage; May improve memory and reduce risk of Alzheimer’s among the elderly
- Magnesium – One of the essential minerals that enhance memory and learning; supports proper blood flow in the brain
- Flavonoids – Helps protect against neuroinflammation and halt amyloid buildup in the brain; Helps enhance cognitive performance
Although cognitive decline tends to be more apparent with age, that doesn’t mean you shouldn’t look after your brain health in your younger years.
As chlorella supplies your brain with essential nutrients, this may help reduce the long-term effects of nutrient deficiencies — not just for brain health but for your overall health and well-being.
6. Reduce the Impact of Fatigue and Stress on the Brain
Several factors contribute to mental fatigue. This includes a weak immune system; deficiencies in nutrients like magnesium; gut dysbiosis or candida yeast overgrowth; high levels of cortisol, which are stress hormones; and heavy metal toxicity. It may also be caused by a malfunctioning hypothalamus, which causes the adrenal glands to become sluggish.
Regardless of the cause, fatigue can significantly impact brain function, affecting concentration, attention, decision-making, mood, and other cognitive processes. This, in turn, can impact our overall health and well-being.
Thankfully, chlorella is rich in B vitamins, vitamin C, iron, zinc, magnesium, and other immune-boosting nutrients that can help increase energy levels, reduce mental fatigue, and boost overall well-being.
This is reflected in a study wherein chlorella supplementation was found to protect against oxidative stress and increase tolerance for fatigue.
In addition, chlorella is a good source of complete protein, healthy fats, and dietary fiber — which are all important for energy production and regulation. So by regulating energy levels, chlorella may help reduce the impact of fatigue, which, in turn, enhances or protects cognitive performance.
