**Park City Plunge: Is Skiing Stealing Youthful Enzymes?**

The biting wind whips across your face as you carve down the slopes of Park City. The thrill is undeniable, but what’s happening inside your body? For those of us over 40, pushing our limits on the mountain demands more than just skill; it requires a strategic approach to maintaining our cellular health, specifically our NAD+ levels.

NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme involved in countless cellular processes, including energy production and DNA repair. As we age, our NAD+ levels naturally decline, impacting everything from muscle function to cognitive clarity. Intense physical activity, especially at high altitudes like Park City, can further deplete these vital reserves.

So, how do we combat this and keep shredding the gnar? Let’s dive into a biohacking protocol tailored for the mature Park City skier.

First, understand the challenge. Downhill skiing, particularly the aggressive style favored by many in Park City, is a high-intensity, intermittent activity. This means bursts of anaerobic effort followed by periods of relative rest. This pattern, combined with the reduced oxygen availability at altitude (Park City sits at 7,000 feet!), creates significant oxidative stress. Oxidative stress damages cells and consumes NAD+ in the process of repair.

A common mistake is focusing solely on post-ski recovery. While crucial, pre-ski preparation is equally important. Think of it like priming your engine before a race.

Here’s a step-by-step protocol, incorporating readily available resources in Park City:

1. Pre-Ski NAD+ Boosting (1-2 hours before hitting the slopes):

   • Niacinamide (Vitamin B3): A readily available precursor to NAD+. Look for sustained-release formulations at local health stores like GNC or The Vitamin Shoppe on Main Street. Start with 500mg and assess your tolerance. Niacinamide avoids the “niacin flush” associated with niacin, making it more comfortable for pre-exercise consumption.
   • Trimethylglycine (TMG) or Betaine Anhydrous: Supports methylation, a crucial process for NAD+ synthesis. Find it at Park City Nutrition or online retailers. A dose of 500-1000mg is generally recommended.
   • Hydration with Electrolytes: Altitude exacerbates dehydration. Add electrolytes like sodium, potassium, and magnesium to your water. Nuun tablets, available at Jans Mountain Outfitters, are a convenient option.

2. During Skiing:

   • Consistent Hydration: Carry a hydration pack and sip water throughout the day.
   • Strategic Snacking: Opt for nutrient-dense snacks like trail mix with nuts and seeds, or energy bars with a good balance of carbohydrates, protein, and healthy fats. Avoid sugary snacks that lead to energy crashes.

3. Post-Ski Recovery (Immediately after skiing):

   • Nicotinamide Riboside (NR) or Nicotinamide Mononucleotide (NMN): These are more direct NAD+ precursors than niacinamide. While availability can vary, some specialized health stores in Park City, like Integrative Health Centers, may carry them. Start with a low dose (100-200mg) and gradually increase as tolerated.
   • Resveratrol: A potent antioxidant that supports NAD+ salvage pathways. Look for trans-resveratrol supplements at local pharmacies or health food stores. A dose of 500mg is a good starting point.
   • Protein and Creatine: Essential for muscle repair and recovery. A protein shake with added creatine monohydrate (5g) is a convenient option.
   • Epsom Salt Bath: Magnesium sulfate in Epsom salts can help relax muscles and reduce inflammation. Soak for 20-30 minutes.

4. Nutrition Plan (Ongoing):

   • Focus on NAD+ Boosting Foods: Incorporate foods rich in tryptophan (turkey, chicken), niacin (tuna, mushrooms), and other B vitamins.
   • Prioritize Antioxidant-Rich Foods: Berries, leafy greens, and colorful vegetables help combat oxidative stress. The Park City Farmers Market (seasonal) is a great source for fresh, local produce.
   • Limit Alcohol Consumption: Alcohol depletes NAD+ and hinders recovery. While après-ski drinks are tempting, moderation is key.

Challenges and Pitfalls:

• Altitude Sickness: This can significantly impact NAD+ levels and overall performance. Acclimatize gradually and consider altitude sickness medication if necessary. Consult with a doctor at Intermountain Healthcare in Park City.
• Supplement Quality: Not all supplements are created equal. Choose reputable brands that undergo third-party testing for purity and potency.
• Individual Variability: Everyone responds differently to supplements and dietary changes. Start with low doses and gradually increase as needed, paying close attention to how you feel.
• Overdoing It: Pushing yourself too hard, especially when fatigued, can lead to injury and further deplete NAD+ levels. Listen to your body and take rest days when needed.

Real-World Application:

Imagine a 55-year-old avid skier named Mark who lives in Park City. He’s noticed a decline in his energy levels and recovery time after a day on the slopes. By implementing this protocol, Mark can potentially:

• Experience improved energy levels throughout the day.
• Reduce muscle soreness and stiffness.
• Enhance cognitive function and focus.
• Potentially slow down the aging process at a cellular level.

Important Considerations:

This protocol is not a substitute for professional medical advice. Consult with your doctor before starting any new supplement regimen, especially if you have any underlying health conditions. Consider working with a registered dietitian or functional medicine practitioner in Park City to personalize your nutrition plan and optimize your NAD+ levels.

By understanding the impact of intense skiing on NAD+ levels and implementing a strategic biohacking protocol, active adults over 40 can continue to enjoy the thrill of the slopes in Park City for years to come, while maintaining youthful enzyme function and overall well-being. Remember, it’s not just about the descent; it’s about the ascent to optimal health.
