A reasonable supplemental dose for adults is eight to fifteen milligrams of zinc daily taken with food to prevent nausea.

Zinc picolinate and zinc bisglycinate are the best-absorbed forms.

Zinc competes with copper for absorption, so long-term supplementation above fifteen milligrams should be paired with one to two milligrams of copper to maintain proper balance.

Zinc is required for the activity of over 300 enzymes in the human body.

It is essential for immune function, DNA synthesis, wound healing, testosterone production, thyroid function, taste and smell, and cellular repair.

It is also one of the most commonly deficient minerals in adults over 50, with an estimated 30% of older adults failing to meet minimum requirements. 🧵

The richest dietary sources of zinc are oysters, which contain more zinc per serving than any other food, followed by red meat, shellfish, pumpkin seeds, hemp seeds, legumes, and nuts.

Plant-based sources contain phytates which bind zinc and reduce absorption significantly.

People eating primarily plant-based diets require higher zinc intake to compensate for this reduced bioavailability.

Practical steps to protect yourself from artificial light after dark include dimming all lights in your home after 8 PM, switching to warm amber or red bulbs in living areas and bedrooms, wearing blue light blocking glasses in the evening, keeping your bedroom as dark as possible during sleep, and establishing a consistent wind-down period of at least 60 minutes before bed without bright light exposure.

For virtually all of human history, darkness fell after sunset and the only light available came from fire.

That changed completely in the last 150 years.

Artificial light after dark is now so ubiquitous that most people have never experienced true darkness.

The biological consequences of this shift are profound and still being fully understood. 🧵

The long-term health associations with chronic light-at-night exposure are serious.

Epidemiological studies consistently link high nighttime light exposure to elevated rates of breast and prostate cancer, obesity, type 2 diabetes, depression, and cardiovascular disease.

Night shift workers, who experience the most severe form of this disruption, show dramatically higher rates of all of these conditions.

Adopting a Mediterranean dietary pattern does not require Mediterranean geography, income, or recipes.

The actionable steps are straightforward.

Switch to extra virgin olive oil as your primary cooking and finishing fat.

Eat fish twice a week.

Make vegetables and legumes the foundation of most meals.

Replace refined grains with whole grains.

Snack on nuts instead of ultra-processed foods.

These shifts alone capture the majority of the benefit.

Hundreds of diets have been studied for their effects on longevity and disease prevention.

One has consistently outperformed every alternative across cardiovascular disease, cognitive decline, cancer, diabetes, and all-cause mortality.

The Mediterranean diet is not a trend.

It is the most validated dietary pattern in the history of nutritional science. 🧵

The cognitive protection offered by this dietary pattern is particularly striking.

People who adhere closely to Mediterranean eating show significantly slower cognitive decline, lower rates of Alzheimer's disease, and better preserved brain volume on MRI as they age.

The combination of polyphenols from olive oil and vegetables, omega-3 fatty acids from fish, and fiber from legumes appears to protect the brain through multiple simultaneous pathways.

The most studied effective dose is three to five grams of creatine monohydrate daily taken consistently.

Timing is largely irrelevant.

Loading phases are unnecessary for long-term use.

Creatine monohydrate is the best-studied form and significantly more affordable than newer formulations with little additional evidence behind them.

It is safe for long-term use in healthy adults with no evidence of kidney damage at recommended doses.

Most people associate creatine with gym culture and muscle building.

That association has obscured the fact that creatine is one of the most studied, safest, and broadly beneficial supplements in existence.

Its effects on brain health, cognitive function, and healthy aging are now among the most compelling areas of research in nutritional science. 🧵

For older adults, the benefits extend further.

Creatine supplementation in people over 55 consistently shows improvements in muscle strength and power, reduced age-related muscle loss, better bone density outcomes when combined with resistance training, and emerging evidence for neuroprotective effects against cognitive decline.

It is one of the few supplements that genuinely earns the term evidence-backed for the aging population.
