Surprising Benefit of Vitamin C

From eNewsletter 8/6/2025

DID YOU KNOW that researchers publishing in Frontiers in Nutrition examined the the association between vitamin C intake and cognitive function in older US adults? While vitamin C has many attributes, cognitive function had never been studied until now.

Participants with the highest vitamin C intake showed significantly better performance on the Auditory Fluency Test and the Digit Symbol Substitution Test compared to those with the lowest intake (500 mg versus 120 mg.).

For the first time, vitamin C exhibited cognitive benefits for older adults.

DID YOU KNOW that yet another negative artificial sweetener study was just published? It seems like every week there's a new study on the negative effects of zero calorie sweeteners such as sucralose, aspartame, and erythritol. This time it's erythritol.

A study from Journal of Applied Physiology found that erythritol triggers a cascade of cellular changes that could raise stroke risk by ramping up harmful oxidative stress inside cells, disrupting protective nitric oxide pathways, and blunting the brain’s natural clot-busting abilities. Erythritol caused a 75% increase in harmful cellular stress and reduced protective nitric oxide production by 20%. The sweetener increased blood vessel constrictor production by 30% and completely blocked the normal clot-fighting response. This was after consuming only one beverage with erythritol.

Please check your food, beverage, and alternative sweetener labels for erythritol. If you see something that has it, throw it away!

DID YOU KNOW that according to the results of a study from BMJ Occupational & Environmental Medicine, melatonin can help reverse DNA damage done by poor sleep? Many are unaware that melatonin, a hormone known for its role in regulating sleep, is also a powerful antioxidant.

The participants, who performed night shift work, took either 3 mg. of melatonin or placebo. The melatonin group showed an 80% increase in a urinary marker exhibiting the body’s natural DNA repair mechanism.

This is important because for those who have suffered from years of poor sleep, whether due to night shifts, insomnia or lifestyle factors, melatonin can help mitigate further damage by improving the efficiency of the body’s natural repair processes, even if it does not directly help your sleep.

While safe for most, you should still discuss melatonin supplementation with a knowledgable health professional first.
