880. CoQ10 shows up in cellular energy production, in antioxidant defense, and increasingly, in marketing aimed at anyone over fifty. It's sold for energy, for athletic performance, and especially to the millions of people taking a statin, since those medications really do lower CoQ10 levels in the blood.

So who genuinely benefits? In this episode, Monica sorts the credible case from the promotional one. She covers why your body makes most of its own CoQ10 rather than getting it from food, what statins actually do to your levels and whether that matters, and what the evidence says about the claim that CoQ10 relieves statin-related muscle pain. You'll also hear the better-validated steps to try before reaching for a supplement, why she compares this situation to glucosamine and joint pain, how to take CoQ10 if you decide to test it yourself, and why the energy-boosting claims deserve real skepticism.

879. Are you eating too much protein, or not enough? The honest answer is that the question itself is flawed, because there's no single number that fits everyone.

In this episode, Monica breaks down why protein needs shift across a lifetime. The mTOR "growth switch" inside your cells runs hot during childhood, powering the tissue-building that young bodies require. In your 30s and 40s, dialing protein back may nudge cells toward repair and cleanup instead. And after 50, when muscle naturally starts to decline, eating more actually helps preserve strength, mobility, and bone health well into later years.

She also puts the recent longevity headlines in context. A widely covered review of animal studies found that lower protein intake can extend lifespan in flies and rodents, yet those results don't map neatly onto human biology, where lifestyle, genetics, and the rest of your diet all shape how you grow older.

Monica offers a more grounded way to think about protein: match your intake to your age, sex, and activity level, and treat the current RDA as a floor rather than a goal.

878. A tick bite you may not even remember getting can leave you unable to eat a hamburger, a slice of pizza, or a bowl of ice cream. That's alpha-gal syndrome, and it's turning up far outside its original range.

Alpha-gal is a sugar molecule found in the cells of most mammals but not in humans. When a lone star tick injects it under the skin, the immune system can start treating it as a threat. After that, beef, pork, lamb, venison, and sometimes dairy or gelatin can trigger a reaction three to six hours later, which is a big part of why this food allergy goes undiagnosed for years.

Today, Monica breaks down what the research actually shows:

• Why the lone star tick's range is expanding into the Midwest, the Northeast, and eastern Canada
• How alpha-gal syndrome differs from Lyme disease, and why they get confused
• What the CDC's estimate of 450,000 cases means, and why the "1 in 4" figure circulating on social media isn't measuring the same thing
• What a diagnosis means for your diet, including collagen, gelatin, organ meats, and why tolerance varies so much from person to person
• Why symptoms can be worse on some days than others
• Whether the condition is permanent, and what happens to antibody levels over time
• How to lower your risk of tick bites, per the CDC
• Where gene-edited GalSafe pigs fit into the picture

Eight glasses a day. An ounce per pound. A pinch of salt in your water. Everyone has a hydration rule, and most of them came from somewhere other than the research. 

This live episode was recorded in front of an audience at the Friends of the National Arboretum in Washington, DC (@fonarboretum), with an outdoor yoga session led by Bikram Yoga Works (@bikramyogaworks). Thank you to both for making the night possible.

Monica Reinagel, MS, LDN, answers listener questions about hydration and explains what the research actually supports. She breaks down the four phases of hydration, which are intake, absorption, retention, and distribution, and explains why sodium and glucose work together to pull fluid out of your digestive system and into your tissues faster than water alone. That mechanism is exactly what an electrolyte drink mix like Liquid I.V. is built around, which is why it can be such a useful tool when you are sweating hard, training, traveling, or just trying to keep up on a hot day.

Monica also covers how much water you really need each day, how much of it you already get from food and other beverages, and how much fluid and sodium you lose through sweat.

Plus, she takes listener questions on whether sugar free electrolyte drinks work as well as the sugared kind, how to think about sodium guidelines when you are sweating heavily, whether it is possible to drink too much water, whether a pinch of salt or a squeeze of lemon does anything, whether coffee and tea count toward your daily fluids, what apple cider vinegar in your morning water actually does, and whether reverse osmosis water needs minerals added back in.

Topics include hydration, electrolytes, sodium, healthy habits, nutrition myths, viral nutrition claims, sports drinks, caffeine, and evidence based nutrition.

877. L-theanine, an amino acid found in tea leaves, is having a moment with longevity enthusiasts and menopause influencers alike, promoted to calm anxiety, clear brain fog, improve sleep, and slow aging. But does the research hold up? In this episode, Monica breaks down what the studies on L-theanine actually show about attention, sleep quality, stress, and cellular aging, and why a cup of coffee or a short nap might do just as much for your focus.

This is the expert roundtable on healthy aging that Monica participated in with USNWR that triggered this episode on theanine.
