The science behind MCT oil keeps getting stronger — and 2025 research is adding even more weight to its benefits for muscle recovery and metabolism.
A 2025 clinical trial involving over 1,000 post-stroke patients showed that combining 40 g/day of MCT oil or powder with resistance training significantly improved grip strength and physical function compared to exercise alone, reinforcing MCT’s therapeutic potential in muscle recovery.
Another recent randomized study from Japan found that healthy older adults who took 18 g/day of MCTs for three months showed notable shifts in muscle metabolism. Advanced PET/CT imaging revealed reduced glucose uptake and increased muscle density in key muscles used for walking.

While an apple a day may not completely keep the doctor away, it can still offer real health perks. Apples are packed with polyphenols and phytochemicals which help reduce the risk of chronic illnesses like heart disease, diabetes, and even some forms of cancer. Regular consumption has been linked to lower cholesterol, improved blood sugar regulation, and even modest weight loss.
Much of the health-boosting power lies in apple's peel. The skin contains the majority of the fruit’s polyphenol compounds, which possess antioxidant and anti-inflammatory properties. These nutrients play a role in reducing oxidative stress and controlling sugar absorption, key factors in managing chronic diseases.
Studies suggest apples may not drastically reduce doctor visits, but daily eaters are statistically healthier and less likely to rely on prescription medication.
Eczema is often treated like a skin issue, but Gary Brecka says the problem starts much deeper — in the gut. On his Ultimate Human Podcast, the human biologist explains that eczema is a full-body immune response tied to gut imbalances, histamine overload, and nutrient deficiencies. Many people with eczema lack beneficial gut bacteria, experience leaky gut, and struggle to clear histamine properly, which fuels chronic inflammation and flare-ups.
Brecka’s solution focuses on restoring internal balance. This includes cutting out gut-disrupting foods, adding collagen-rich bone broth and glutamine, and replenishing nutrients like Vitamin D3, Zinc, and Omega-3s. Stress reduction, consistent sleep, and proper hydration are also key. Probiotics, digestive enzymes, and prebiotic foods help build a more resilient gut — leading to calmer, healthier skin.

On a recent episode of her podcast FoundMyFitness, Dr. Rhonda Patrick delivered a deep dive into the science of coffee and its impressive role in slowing aging and extending lifespan.
This powerful effect is due to coffee’s rich mix of chlorogenic acids, polyphenols, and antioxidants, which reduce inflammation, protect your genes, and nourish beneficial gut bacteria. The result? Coffee drinkers have a younger epigenetic profile, better metabolic health, and up to 27% lower risk of death from all causes.
Whether caffeinated or decaf, coffee helps guard against cardiovascular disease, type 2 diabetes, and certain cancers— especially liver and endometrial cancer. Even better, the caffeine in regular coffee is linked to a 30-40% reduced risk of brain aging diseases like Alzheimer’s and Parkinson’s.

Creatine — once relegated to gym aisles — is gaining serious attention from scientists for its wide-ranging health benefits. Beyond its well-known roles in muscle and fat regulation, recent studies reveal that creatine may support heart health, bone density, mood stabilization, and enhanced brain function.
One small trial even showed cognitive improvement in Alzheimer’s patients, suggesting that increasing energy capacity in the brain (which consumes 20% of our body's energy) can counteract oxidative stress and inflammation .
While not a miracle pill, experts agree that fused with a healthy lifestyle — balanced diet, exercise, quality sleep — creatine offers a valuable boost to muscle strength, brain health, and long‑term vitality.

🥥 MCT Oil Gains More Muscle-Boosting Backing
New clinical trials confirm that MCT oil, combined with resistance training, significantly enhances muscle recovery and metabolism in both stroke survivors and older adults.
🍏 Apple Peel = Health Power
Apples — especially the peels — are rich in polyphenols that help lower cholesterol, regulate blood sugar, and reduce chronic disease risk.
🪟 Eczema Is a Window to Gut-Immune Imbalance
Eczema may reflect internal gut dysfunction and nutrient deficiencies, with recovery tied to gut healing, stress reduction, and targeted supplementation.
☕ Coffee Slows Aging
Coffee's polyphenols and antioxidants educe inflammation, protect genes, and lower overall mortality risk — regardless of caffeine content.
🧘 Creatine for Body + Brain
Emerging research links creatine to improved heart health, brain function, and even cognitive support in Alzheimer’s patients.
