Ticks are best known for transmitting infections such as Lyme disease. They can also trigger something entirely different: an immune response that leaves some people allergic to mammalian meat. New evidence involving the western blacklegged tick makes the distinction particularly relevant in Oregon and the Pacific Northwest.

Three major 2026 studies have reopened one of the most important questions in women's brain health: does estrogen exposure around menopause influence later dementia and Alzheimer’s risk? The new findings are encouraging, especially for estrogen-only therapy and treatment closer to menopause, but they do not prove that hormone therapy prevents dementia.

Protein quantity matters for maintaining muscle, but the food supplying that protein may matter just as much for long-term health. Research increasingly favors a plant-forward mix of legumes, nuts, seeds, soy, whole grains and seafood while distinguishing those foods from processed meat and other protein sources. Here is what the evidence actually tells us about plant and animal protein, muscle, cardiovascular health and healthy aging.

Third-party tested” sounds reassuring, but the phrase alone tells you surprisingly little. USP Verified and NSF certification involve defined testing, manufacturing review and ongoing oversight, while other quality claims may refer to a single laboratory test or manufacturer-supplied certificate. Here is what potency, purity, identity and certification actually mean, and what they do not tell you about whether a supplement works.

Protein needs more attention after 50 because maintaining muscle becomes harder with age, especially during menopause, illness, calorie restriction and weight loss. Current U.S. dietary guidance now targets 1.2–1.6 g/kg per day, but total intake is only part of the equation. Meal size, protein quality and resistance training all influence how effectively that protein supports muscle.

GLP-1 medications can make meaningful weight loss possible, but eating substantially less also changes nutritional priorities. Protein, resistance training, fiber, hydration and adequate micronutrient intake deserve more attention when appetite falls. Supplements can help when food intake no longer covers those needs, but the goal is better-quality weight loss, not a larger supplement stack.

Supplements are often treated as separate from medication lists, but calcium, iron, magnesium, potassium, vitamin K, biotin and several herbal products can meaningfully change drug absorption, drug effect or laboratory results. Some prescription medications also change nutrient status over time. Here are the interactions worth knowing and the ones most often missed.

A multivitamin, bone formula, B-complex and immune supplement may each look reasonable on their own. Taken together, they can quietly duplicate vitamin D, B6, zinc, iron, folate and other nutrients. Supplement stacking is one of the easiest ways to turn appropriate supplementation into unnecessary or excessive dosing.

Many vitamins and minerals can be taken together, but a few combinations deserve more attention. Calcium can interfere with iron absorption, high-dose zinc can lower copper, and minerals such as calcium, magnesium, iron and zinc can reduce the absorption of several medications. The important issue is often timing, dose and medication interaction rather than whether two nutrients are inherently incompatible.

Vitamin B12 deficiency can cause fatigue, anemia, numbness, balance problems and cognitive symptoms, yet it can be missed when clinicians rely on anemia or a single serum B12 result. Here is how B12 is absorbed, who is most at risk, when methylmalonic acid testing helps, and why the cause of a low B12 matters.

Vitamin D is essential, but more is not automatically better. Here is what current evidence says about supplementation, blood testing, deficiency, and high-dose use.

Multivitamins were once easy to dismiss as little more than nutritional insurance. Newer randomized research from the COSMOS program suggests a more nuanced picture, with modest benefits in cognitive aging and small changes in selected biological-aging markers. The evidence does not show that multivitamins extend lifespan, but it does support reconsidering their role as a practical way to help fill nutritional gaps.
