When you eat can make a difference in your health. Research suggests that eating within a regular daily time frame may help lower certain signals linked to inflammation. This approach is called time-restricted eating, and it offers a simple way to support your health alongside nutritious food and regular exercise. I have had many patients report dramatic improvements in their health with this simple timing technique.

Creatine is one of the most popular nutritional supplements, but many people still think of it primarily as something used by bodybuilders and athletes. That view is changing.

For years, men have heard two conflicting messages about testosterone. One says low testosterone is bad for the heart. The other says testosterone therapy could trigger a heart attack or stroke. Both messages created confusion in my patients and, frankly, in the medical community.

Aging is the strongest risk factor for gradual changes in cognitive function. Age-related cognitive decline may involve reduced working memory, slower processing of information, and greater difficulty handling several tasks at the same time.

You may have heard the term “leaky gut,” but the medical term is increased intestinal permeability. Your intestinal lining acts like a highly selective barrier. It allows nutrients to pass into the bloodstream while helping keep out bacteria, toxins, and other substances that should stay inside the digestive tract.

B vitamins do far more than support energy. They play essential roles in brain function, stress response, methylation, and healthy homocysteine levels—but the form of the vitamin can matter, especially when it comes to folate and MTHFR variants. Discover which B vitamins your body needs, where to find them, and what the latest research says about methylfolate.

NAC is far more than a basic antioxidant. From supporting glutathione production and liver detoxification to helping clear respiratory mucus, regulate inflammation, and support brain and metabolic health, this versatile nutrient has an impressive range of uses.

A groundbreaking study in JAMA Cardiology reveals that daily Vitamin K2 (MK-7) supplementation can significantly slow the progression of coronary artery calcification, offering a potential nutrient-based strategy to protect your cardiovascular health. This discovery challenges the traditional view that arterial hardening is inevitable, highlighting a critical and often-overlooked factor in long-term heart safety.

Recent research indicates that Parkinson’s disease originates in the gut microbiome, with environmental factors like pesticide exposure and dietary imbalances driving the condition long before traditional motor symptoms appear. Consequently, restoring gut health through diet and microbiome support has emerged as a promising strategy for managing the disease and reducing overall risk.

Research reveals that female hormones and the gut microbiome maintain a constant, bidirectional communication, where each system significantly influences the other's function and health. Declining hormone levels during menopause can disrupt this balance by impairing gut barrier integrity and microbial diversity, underscoring the importance of adopting lifestyle habits that support both digestive and hormonal wellness.

Just as "leaky gut" impacts digestive health, blood-brain barrier breakdown, or "leaky brain", may be an early, independent warning sign of cognitive decline. Recent research suggests this barrier, which acts as a security system for your brain, can become damaged, contributing to memory and thinking problems. However, you can actively support your brain's integrity: evidence points to dietary patterns rich in omega-3 fatty acids, flavonoids, and colorful produce as key strategies to help seal this barrier and protect long-term brain health.

Is NMN truly the ultimate longevity molecule, or is it just marketing hype? Modern human clinical trials reveal that supplementing with NMN directly counters age-related NAD+ decline, resulting in measurable improvements in physical stamina, aerobic capacity, sleep quality, and cellular health.

For decades, we’ve been told humans and chimpanzees share 99% of their DNA. But the first-ever complete, gap-free genomic comparison tells a completely different story. Discover how groundbreaking data reveals a massive genetic chasm—especially on the Y chromosome—that challenges conventional evolutionary theory and points to unique creation.

Your liver has an incredible ability to heal itself—if you give it the right tools. Discover how a combination of strategic dietary shifts and research-backed supplements like milk thistle and berberine can target the root causes of fatty liver disease and reverse fat accumulation fast.

For twenty years, uniform warnings deterred millions of women from hormone replacement therapy (HRT). Now, the FDA is correcting course. By embracing the "timing hypothesis," modern medicine finally aligns with integrative care: when started early and tailored to the individual, HRT is a safe, life-changing tool for managing menopause.

Emerging research shows that Time-Restricted Eating (TRE) is a powerful, flexible tool for managing Type 2 diabetes and promoting weight loss. By shifting your meals to an earlier daytime window, you can naturally optimize your metabolism, lower glucose levels, and work with your body’s internal clock.

Declining sperm counts and plunging testosterone levels are increasingly linked to a silent, everyday threat: endocrine-disrupting chemicals (EDCs). In this article, Dr. Stengler exposes the major chemical culprits—including phthalates, BPA, dioxins, pesticides, and toxic heavy metals like mercury—that derail male hormone synthesis at a cellular level. Read on to understand how these ubiquitous environmental toxins block critical signaling pathways, and learn the practical lifestyle modifications, clean-living habits, and detoxification strategies needed to safeguard your hormonal health.

Healthy testosterone production depends on far more than just hormonal signaling—it requires a solid foundation of essential micronutrients. In this article, Dr. Stengler highlights the critical roles that zinc, vitamin D, and magnesium play in male hormonal health. Backed by clinical research, discover how deficiencies in these three nutrients can sub-optimally suppress testosterone levels, and learn the exact dietary, lifestyle, and supplemental strategies needed to naturally optimize your hormone production.

The ketogenic diet is far more than a passing weight-loss trend—it is one of modern medicine’s most extensively studied dietary interventions. By drastically reducing carbohydrates and shifting the body into a metabolic state called nutritional ketosis, the keto diet changes how your cells produce energy. Discover the latest clinical research on how keto impacts drug-resistant epilepsy, Type 2 diabetes, obesity, and fatty liver disease (NAFLD), alongside essential guidelines on managing side effects and targeted supplementation.

Can Vitamin D and Fish Oil Prevent Autoimmune Disease? New Landmark Study With autoimmune diseases steadily on the rise, conventional medicine offers few preventative solutions—until now. In this article, Dr. Stengler breaks down the landmark VITAL study, a gold-standard clinical trial tracking over 25,000 adults for more than five years. The striking results reveal that daily supplementation with Vitamin D3 and marine omega-3s (fish oil) can cut autoimmune disease risk by up to 39%. Discover the fascinating immune-regulating science behind these findings and how to optimize your preventative wellness protocol.
