A medication used by millions (including off-label usage for “longevity” purposes) may alter the fundamental pathways responsible for exercise adaptation. This episode reviews new 2025 data showing reduced improvements in vascular insulin sensitivity, aerobic capacity, and glucose regulation when the medication is paired with structured training. We look at prior evidence of blunted mitochondrial respiration and diminished hypertrophy, along with 2020 transcriptomic findings that paint a more nuanced picture.

The goal: clarify when this medication interferes with exercise-driven improvements in muscle, mitochondria, and vascular function, and when it may support resilience during aging.

There’s a molecule that’s been tentatively identified in the same interstellar material that forms stars and planets, yet it also shapes growth, metabolism, and cognition here on Earth. In several mammalian species,Its absence causes deficiency and it's repletion, resolution; and no, it’s not a vitamin, but should it be?

Its chemistry is analogous to the combination of vitamin B2, vitamin B6 vitamin C, and its role in evolution may trace back to the very beginning of biology.

Serotonin is often described as the “happiness molecule,” but its biology tells a larger story. Nearly every step in serotonin’s synthesis and signaling, from the transport of dietary tryptophan to the enzymes that convert it, is influenced by nutrition.

This episode examines how macronutrients, micronutrients, and gut-derived metabolites shape serotonin availability across the brain and body. Protein and carbohydrate balance determine how much tryptophan enters the brain. Specific vitamins and minerals serve as essential cofactors in its production and turnover, and so on…

Understanding serotonin through this nutritional lens reframes it not as a simple neurotransmitter, but as a metabolic signal connecting diet, metabolism, and mood regulation.

Every few days, your gut rebuilds itself completely - cell by cell, guided by signals we still don’t fully understand. For years, scientists have known that diet can influence this process, but the exact messenger between what we eat and how the gut heals has remained a mystery.

In this episode, we look at new research from MIT that uncovers a surprising link between diet, the immune system, and regeneration in the intestine. It’s a story about how a single nutrient can activate immune cells to release molecules that tell the gut when it’s time to repair.

It challenges the way we think about food, not just as fuel, but as information. Because the gut isn’t just digesting what we eat… it’s listening.

Creatine’s story has been far too small for its biology. Most people still see it as a supplement for strength or cognitive performance, but its most important work happens inside the mitochondria.

In this episode, we explore a side of creatine few people talk about: how it may function as mitochondrial medicine. We’ll break down 3 distinct ways creatine acts in and supports the mitochondria; roles that could reshape how we think about energy, resilience, and cellular health.  And beyond that, how creatine may be one of the few molecules that can both diagnose and treat mitochondrial dysfunction.

In this episode of The Daily Value, we look at new research suggesting that polyphenols might be doing something we never expected — not just acting as antioxidants, but organizing themselves into microscopic structures that can stabilize the very proteins that keep our cells alive. It’s a discovery that could reshape how we think about plant compounds and resilience at the molecular level. We explore how this structural behavior gives new meaning to the idea that diversity matters in our diet — and why the age-old advice to “eat the color spectrum” may be more scientifically accurate than anyone realized.

October 1st (yesterday) was International Coffee Day. In this episode, we trace coffee’s journey from ancient ritual to modern science. Once a sacred brew in Ethiopia and Yemen, coffee now fuels billions daily. In 2025, research is rewriting how we should drink it. In this episode, we uncover why timing intake, keeping coffee unsweetened, and using the right brewing method matter for long-term health. We also look at new data linking clean coffee to lower risk of chronic liver disease. Coffee is more than a morning habit. It’s a multi-molecule that may offer us a method and a blueprint for better well-being.

Why are nearly two-thirds of Alzheimer’s patients women? For decades, the explanation seemed simple: women live longer. But the numbers don’t add up. Even after 80, when survival rates even out, women are still more likely to be diagnosed. A new lead may finally expose what’s been hiding in sex-specific biology.

Parkinson’s disease has long been defined by the death of neurons in the brain. Yet, decades before tremors appear, the first signs emerge quietly in the gut. Recent evidence reveals a puzzling disappearance: microbial pathways that once produced two well-known compounds fall silent. Their absence strips away protective metabolites, erodes the intestinal barrier, and leaves neurons exposed to toxins that ignite α-synuclein fibrils. Could the vanishing of two simple vitamins be an overlooked trigger, and a potential target, in the unfolding mystery of Parkinson’s disease?
