In a review of more than 28,000 adverse-event reports to the FDA over eight years, caffeinated energy drinks and stimulant supplements were linked to serious heart conditions far more often than other products.
Cardiac arrest was reported about 11 times more often in connection with caffeine- and stimulant-containing products vs. products without these ingredients.
Reports involving energy drinks and supplements were about 4.5 times more likely to include heart attacks and four times more likely to include ventricular arrhythmias (abnormal rhythm in the heart’s lower pumping chambers) or heart palpitations.
Similar patterns existed between consumption of caffeinated energy drinks and stimulant supplements and reports of other heart conditions, including elevated heart rate (nearly 3 times more often), chest pain (2.71 times more often) and fainting (about 2 times more often).
Sales of caffeinated energy drinks have more than doubled over the past decade, reaching over $20 billion in 2024.
Overtraining may disrupt the brain's dopamine regulation, leaving levels elevated during rest
University of São Paulo (Brazil), November 3 2026 (Medical Xpress)
Excessive physical exercise affects more than just the muscles; it can also alter brain chemistry. A new study published in the journal Neuroscience reveals that exhaustive training without adequate rest alters the regulation of dopamine in the hippocampus, a brain region closely linked to memory and the regulation of emotions.
When observing mice subjected to an intense exercise routine, researchers noted that dopamine, a neurotransmitter essential for alertness and motivation, remained elevated at a time when the animals should have been resting. If this same mechanism is confirmed in humans, the discovery could help explain why athletes who train excessively often suffer from anxiety, insomnia and chronic fatigue. This would highlight the biological importance of rest for physical performance and mental health.
The authors emphasize that dopamine is not a biological villain because it is essential for pleasure and keeping us awake at the right times. The real problem is the imbalance created when dopamine levels rise at bedtime, as well as the resulting imbalance relative to other neurotransmitters. Mushroom blend shows promise for mind health in Gen Z womenNorthumbria University (UK), November 2 2026 (Frontiers in Nutrition)
Functional mushrooms, particularly Lion’s mane (and Reishi are increasingly marketed for cognitive and mood-related benefits, despite limited evidence to date. This trial examined the effects of four-week supplementation of Lion’s mane and a Lion’s mane and Reishi mushroom blend on mood and wellbeing in Gen Z women experiencing subjective stress and/or anxiety.
A randomised, double-blind, placebo-controlled, trial was conducted. Eighty-four young women (aged 18–26) received either 1.8 g powdered Lion’s mane, 1.8 g powdered Lion’s mane and Reishi mushroom blend, or placebo in capsulated form for 28-days. Mood and wellbeing were assessed at baseline, weekly during the intervention period and at Day 42.
Analysis indicated that the mushroom blend resulted in lower anxiety than Lion’s Mane alone. Secondary interactions for anxiety and stress suggested a pattern of benefits of the mushroom blend over Lion’s mane and placebo at various timepoints. Qualitative data supported this pattern. Significant improvements across all psychological measures were observed regardless of treatment allocation, suggesting participatory benefits alongside intervention effects.
A Healthier Form of Salt Could Prevent Nearly 3 Million Deaths Every Year, Scientists Say George Institute for Global Health (Australia), November 7, 2026 (Scitech Daily) Replacing ordinary salt with a potassium-enriched alternative could prevent nearly three million deaths worldwide each year, according to a new study covering 193 countries. Researchers estimate that a global switch could also prevent more than ten million new cases of cardiovascular and kidney disease annually, offering a potentially powerful way to reduce the health burden of high blood pressure.
Potassium-enriched salt replaces part of the sodium chloride in regular table salt with potassium chloride. It looks, tastes, and performs much like conventional salt in cooking but contains less sodium and provides additional potassium, two changes that can help lower blood pressure. Potassium-rich salts—commonly known as potash—are natural mineral deposits made up of potassium-bearing salts like potassium chloride.
Switching only household table salt could prevent approximately 1.85 million deaths and 6.19 million new cases of cardiovascular and chronic kidney disease annually. Replacing salt exclusively in processed and restaurant foods could prevent another estimated 1.56 million deaths and 5.46 million new disease cases each year under that separate scenario.
Although potassium-enriched salt can help lower blood pressure, it may pose risks for people whose kidneys cannot effectively remove excess potassium from the bloodstream. This can lead to hyperkalemia, a potentially dangerous condition that can disrupt the heart’s electrical activity. People with advanced kidney disease and those taking certain medications that increase blood potassium levels require particular caution.
