A normal fasting glucose does not always mean normal metabolic health. During early insulin resistance, the pancreas may compensate by producing more insulin, keeping glucose deceptively normal. Measuring fasting insulin alongside glucose may reveal this hidden metabolic stress earlier. Learn why fasting insulin, HOMA-IR, A1c, triglycerides, waist circumference, and other markers can provide a more complete picture of insulin resistance and metabolic health.

Glycine is considered a nonessential amino acid because the body can make it—but can it always make enough? Emerging evidence suggests that aging, insulin resistance, oxidative stress, and increased connective-tissue demands may create a mismatch between glycine supply and metabolic need. Learn about possible signs of glycine insufficiency, plasma amino-acid testing, glycine-rich foods, sleep dosing, collagen, glutathione, and GlyNAC.

Uric acid is best known for gout, but elevated levels are also associated with hypertension, kidney dysfunction, and cardiovascular risk. Research suggests that uric acid may influence blood pressure through oxidative stress, reduced nitric oxide, renin-angiotensin activation, renal vasoconstriction, and altered sodium handling. Learn how uric acid, kidney function, and hypertension may form a self-reinforcing cycle—and why lowering uric acid is not always the same as lowerin

Could a medication long used for bipolar disorder also help support mood, protect the brain, and promote healthy aging at much lower doses? Emerging research suggests low-dose lithium may enhance neuroplasticity, reduce neuroinflammation, improve mitochondrial function, and influence pathways involved in depression and cognitive decline. Learn the current science, safety considerations, and how a systems-based evaluation may improve outcomes.

Quercetin is a plant compound found in onions, apples, berries, and capers. Emerging research suggests that certain forms may influence glucose absorption and some of the transport pathways associated with SGLT activity. Could this help support diabetes, insulin resistance, weight management, and metabolic health? Learn what is established, what remains theoretical, and why quercetin should complement—not replace—appropriate medical treatment.

Alpha-lipoic acid (ALA) is a powerful antioxidant that plays an important role in metabolism, weight management, and brain health. Research shows it may improve insulin sensitivity, support healthy blood sugar regulation, promote fat metabolism, and help protect against cognitive decline by reducing oxidative stress and improving mitochondrial function. For patients focused on longevity and prevention, ALA may represent one of the most versatile evidence-based nutritional int

The Monocyte-to-Lymphocyte Ratio and Its Emerging Role in Cognitive Decline. One of the cheapest test that is currently available. Can a Simple CBC Predict Future Dementia Risk? Understanding how the Monocyte-to-Lymphocyte Ratio (MLR) may reveal early inflammatory changes associated with Alzheimer’s disease, vascular dementia, and accelerated cognitive aging. Quick Look Could a routine complete blood count reveal early warning signs of future dementia? A growing body of evide

L-glycine is a simple amino acid with surprisingly powerful health benefits. Research suggests it may improve sleep quality, reduce anxiety, support collagen formation, enhance liver detoxification, improve metabolic health, and promote healthy aging pathways linked to longevity. Unlike conventional sedatives, glycine works naturally by supporting the body’s own restorative processes, making it one of the most overlooked compounds in nutritional and longevity medicine.

For decades, nutrition science focused primarily on omega-3 and omega-6 fatty acids. New research now suggests that C15:0 (pentadecanoic acid), a naturally occurring odd-chain saturated fatty acid, may represent an overlooked essential nutrient. Early evidence indicates C15:0 may support mitochondrial function, reduce inflammation, stabilize cell membranes, improve insulin sensitivity, and potentially influence longevity pathways involved in healthy aging.

Most people associate uric acid with gout, but emerging research suggests it may be far more important. Elevated uric acid has been linked to hypertension, cardiovascular disease, kidney disease, insulin resistance, endothelial dysfunction, and accelerated aging. While many laboratories consider levels up to 7.0 mg/dL “normal,” evidence suggests that levels below 5.5 mg/dL—and ideally near 5.0 mg/dL—may provide greater protection against vascular injury and chronic disease.
