Iron is a double-edged sword.
Essential for life but toxic in excess.
Know your numbers: check your iron, ferritin, and iron saturation regularly.

Cancer loves high iron (just like high copper)!

That’s why it’s essential to keep tabs on your iron levels.

👉 Men are more prone to high iron since they don’t lose blood regularly through menstruation or childbirth.
👉 Women, on the other hand, are more likely to run low on iron during their menstruating years—but after menopause, iron can build up much faster.
👉 Genetics also play a role—some people accumulate excess iron regardless of age or s*x.

On bloodwork, high serum iron and iron saturation usually show up first, with ferritin following.

The key is knowing your unique levels—and how to adjust your diet and mineral balance accordingly.

This is why balancing minerals is at the core of all my 1:1 programs.

Knowledge on your body chemistry is power.

This is a huge victory for women’s health. It’s about time the outdated and misleading warnings were removed. I’ve been prescribing Bioidentical HRT and TRT for over 20 years—and I’ve seen firsthand how life-changing it is for women going through menopause - glad to see the science finally catching up.

Is Sugar the Silent Killer Behind Heart Disease?
A wave of new research is making something very clear: eating too much sugar may be far more dangerous for your heart than we once believed—even if your cholesterol looks normal and you’re not overweight. High sugar intake can drive up blood pressure and trigger the liver to pump out harmful fats, placing major strain on your cardiovascular system. In fact, some studies show that when added sugars make up 25% or more of your daily calories, the risk of dying from heart disease can more than double.

Why Excess Sugar Is So Damaging to Your Heart

📌 Chronic inflammation: A high-sugar diet promotes ongoing inflammation, which injures blood vessels and speeds up the development of plaque in the arteries.
📌 Higher blood pressure: Sugar can raise blood pressure, one of the strongest predictors of heart disease and stroke.
📌 Elevated triglycerides: High sugar intake dramatically boosts triglycerides—fat particles in the bloodstream strongly tied to cardiovascular risk.
📌 Insulin resistance: Too much sugar can cause insulin resistance and type 2 diabetes, both of which massively increase the likelihood of heart disease.

Cholesterol still matters, of course—but the science now shows that excess sugar is just as powerful, if not an even more direct driver of heart damage. Cutting back on added sugars is one of the most impactful steps you can take to protect your heart and your long-term health.

The Brain Thrives on Novelty!

Neuroscientists are uncovering a powerful truth about how the brain ages: it’s not time that slows it down, it’s repetition. The more predictable daily life becomes, the faster neural activity declines, as the brain stops forming new connections and settles into familiar loops. In short, comfort zones quietly age the mind.

The brain thrives on novelty. Every time it encounters something new, a new place, sound, skill, or challenge, it triggers neuroplasticity, the process through which neurons grow new connections and strengthen existing ones. This constant adaptation keeps the brain sharp, curious, and young. But when routines take over, those same pathways become rigid, and creativity, memory, and problem-solving begin to fade.

Research using brain imaging shows that people who consistently learn new skills, travel, or engage in mentally demanding activities maintain higher gray matter volume and stronger neural connectivity, even as they age. On the other hand, repetitive lifestyles show measurable decreases in brain metabolism and flexibility, early signs of cognitive aging.

Breaking monotony doesn’t require major life changes. Learning a language, taking a different route to work, trying a new hobby, or simply engaging in meaningful conversation can spark neural growth. Each new experience acts like a workout for the mind, reigniting curiosity and keeping neurons active.

Time doesn’t age the brain; repetition does. The secret to staying mentally young lies in surprise, challenge, and learning. Every new experience gives the mind another reason to stay awake.

NAD+: Your hormones, your peptides, your supplements, your workouts, even your carefully designed nutrition program—all of them work better when your NAD+ is optimized. Why? Because NAD+ is the master molecule that fuels your mitochondria, powers cellular repair, slows aging, and amplifies every investment you make in your health. Without NAD+, your biohacks are running on half power. With NAD+, they transform into your ultimate edge.

Doctors Warn Against Mouth Taping During Sleep.
MONDAY, Sept. 29, 2025 (HealthDay News) — Taping the mouth shut before bed may seem like a quick fix for better sleep, but doctors are raising serious alarms about this viral social media trend.
While devotees claim it can improve sleep and reduce snoring, health professionals say the practice is unproven and comes with significant risks, according to The Associated Press.
“The studies behind mouth tape are small, the benefits are modest and the potential risks are there,” said Dr. Kimberly Hutchison, a neurologist and sleep medicine expert at Oregon Health & Science University in Portland.
These risks include the potential to worsen underlying conditions like sleep apnea or, in extreme cases, cause suffocation.
The nose acts as a natural filter for dust and allergens. While nasal breathing is preferred most of the time, doctors emphasize mouth breathing is not a major health issue for most adults.
Breathing through the mouth at night can lead to a dry mouth, irritated throat and dental problems. But, experts warn, the solution isn't to tape the mouth shut.
Dr. David Schulman, a sleep doctor at Emory University in Atlanta, said there are far safer alternatives.
He recommends exploring options like prescription mouthpieces or a CPAP machine for those with sleep disorders. Lifestyle changes, such as quitting smoking or losing weight, can often improve sleep quality and reduce mouth breathing, Schulman added.
Why a person is breathing through the mouth while sleeping is the key issue. It can be a symptom of a more serious condition, such as obstructive sleep apnea, where the airway is blocked during sleep. This disorder is linked to both mouth breathing and snoring and is typically treated with a CPAP machine.
“The reason sleep apnea can be bad is that any decrease in the quality of sleep can affect you day to day or over the course of your life,” said Dr. Brian Chen, a sleep doctor at the Cleveland Clinic. "Depending on how bad the sleep is, you may just feel sleep deprived or require more sleep."
Rather than risking a dangerous trend, Schulman advises people to seek a proper diagnosis. A sleep test, which can often be done at home, is the best way to understand the root of the problem.
“It’s always better to know than not know,” he said.
From there, patients can make treatment decisions based on the specific cause of the mouth breathing, he added.
