Studies Link Vitamin C to Cognitive Function, Memory and Mood Regulation – NaturalNews.com
Recent studies indicate the nutrient may play a role in cognitive performance, memory and mood regulation across age groups, researchers said. The body cannot produce vitamin C and depends entirely on dietary intake or supplementation, the report stated. K.C. Craichy noted in "Super Health: Seven Golden Keys to Lifelong Vitality" that vitamin C is a well-known antioxidant that helps keep the brain healthy [1].
Vitamin C’s Role in the Central Nervous SystemVitamin C enters the brain via glucose and sodium active transport from the blood, a 2019 review in Neurochemistry International described, as cited in additional context. Neurons and glial cells rely on adequate absorption and transfer of the vitamin, according to the same review.
The nutrient acts as an antioxidant and helps recycle other antioxidants such as vitamin E and glutathione, stated a 2018 study in Antioxidants, referenced in additional context. Antioxidants including vitamin C are involved in bolstering immune and detoxification systems and keeping the brain healthy, according to Craichy [1]. David Herzog’s "Natural to SuperNatural Health" notes that supplements including vitamin C help increase dopamine levels and support blood flow, energy, focus and impulse control [2].
Cognitive Performance in Older AdultsA 2019 review in Nutrients found that higher blood levels of vitamin C were positively correlated with cognitive performance in adults aged 66 to 90, researchers said. A recent study published in PLOS One examined roughly 2,044 adults in Japan with a median age of 69 and found that those with higher plasma vitamin C levels had greater gray matter volume and stronger connectivity in the brain’s default mode network, according to a report on NaturalNews.com [3].
Even when vitamin C levels declined elsewhere in the body due to insufficient intake, brain concentrations remained relatively high, the review noted. The antioxidant role of vitamin C may protect against oxidative stress that affects cognitive function during aging, researchers said. A NaturalNews.com piece stated that vitamin C enhances immune function by protecting cells from oxidative stress and is essential for collagen synthesis, but its antioxidant properties also support overall health, including brain health [4].
Focus and Mood in Younger AdultsA study in the European Journal of Nutrition found that vitamin C supplementation increased work motivation and attentional focus in adults aged 20 to 39, according to additional context. Participants showed better performance on cognitive tasks requiring sustained energy, the study reported.
A 2018 Antioxidants study, cited in additional context, found that individuals with the highest plasma vitamin C concentrations were more likely to have an elevated mood, with inverse correlations to sadness, anger and confusion. Another NaturalNews.com article noted that grapes, which are rich in vitamin C and other antioxidants, support cognitive function and immune defense [5]. Supporting neurotransmitter function is a key mechanism, as vitamin C is critical for synthesizing norepinephrine, a neurotransmitter involved in mood regulation, according to the 2018 review in Antioxidants.
Neurotransmitter Synthesis and ConclusionVitamin C is critical for synthesizing norepinephrine, a neurotransmitter involved in mood regulation, according to the 2018 review in Antioxidants. The vitamin also plays a role in myelin and neuron formation during neurodevelopment, studies cited in additional context indicate.
Supplements that help increase dopamine include tyrosine, grape seed extract, ginkgo biloba along with vitamin C and E and other antioxidants, according to Herzog [2]. These nutrients help increase dopamine as well as blood flow and energy, focus and impulse control, the source stated. Researchers said adequate vitamin C intake is important throughout life for cognitive health and mood support, though supplementation should be discussed with a healthcare provider.
