Have you ever considered the water you drink as a potential source of mineral deficiency? In Taos, New Mexico, nestled high in the Sangre de Cristo Mountains at an elevation of approximately 7,000 feet, the unique environment might be impacting your mineral intake more than you realize. Let’s dive into the specifics of Taos tap water, the challenges of high-altitude living, and how you can ensure you’re getting the minerals your body needs.

Taos tap water, while generally safe to drink, originates from surface water sources and groundwater. This means its mineral content can vary significantly depending on the season and the specific source being tapped. Unlike some areas with naturally mineral-rich water, Taos’s water may not provide sufficient levels of essential minerals like magnesium, calcium, and potassium.

The first step is to understand what’s actually in your water. You can’t fix a problem you can’t measure.

• Order a water test kit: Several reputable companies offer mail-in water testing services. Look for kits that specifically test for mineral content, including calcium, magnesium, potassium, sodium, and iron. A good example is SimpleWater. Their Tap Score kits are comprehensive and provide detailed reports.
• Check the Taos Water and Wastewater Department’s reports: The town is required to publish annual water quality reports. These reports provide a general overview of the water’s composition, but may not be detailed enough for individual mineral concerns.
• Consider a local lab: For a more in-depth analysis, consider using a local environmental testing lab. They can provide more specific information about the mineral content of your water.

Once you have your water test results, compare them to the recommended daily intakes (RDIs) for essential minerals. The National Institutes of Health (NIH) provides detailed information on RDIs for various minerals.

Living at 7,000 feet presents unique physiological challenges. The lower oxygen levels at high altitude can increase your body’s need for certain minerals and electrolytes.

• Increased Respiration: Your body works harder to breathe at higher altitudes, leading to increased fluid loss through respiration. This can deplete electrolytes like sodium, potassium, and magnesium.
• Diuretic Effect: Altitude can act as a diuretic, increasing urine production and further contributing to electrolyte loss.
• Increased Physical Activity: Many Taos residents enjoy outdoor activities like hiking, skiing, and mountain biking. These activities increase sweat production, leading to even greater electrolyte loss.

These factors combined can create a perfect storm for mineral deficiencies, impacting energy levels, muscle function, and overall well-being.

Now that you know the potential issues, let’s explore solutions. Water filtration and mineral supplementation are two key strategies for optimizing hydration and nutrient intake in Taos.

Water Filtration:

Not all water filters are created equal. Some remove beneficial minerals along with contaminants.

• Reverse Osmosis (RO) Filters: While RO filters are excellent at removing contaminants, they also strip the water of almost all minerals. If you use an RO filter, you must remineralize your water afterward.
• Activated Carbon Filters: These filters are effective at removing chlorine, sediment, and some organic compounds, but they don’t significantly alter the mineral content of the water. This is a good option if you’re primarily concerned about taste and odor.
• Mineralizing Filters: These filters add minerals back into the water after filtration. They typically contain a blend of calcium, magnesium, and potassium. Look for filters that use natural mineral sources like calcite and magnesite. APEC Water Systems ROES-75 is a popular RO system that includes a remineralization stage.

Mineral Supplementation:

Choosing the right supplements can be tricky. Here’s a breakdown of essential minerals and how to supplement them effectively.

• Magnesium: Magnesium is crucial for muscle function, nerve function, and energy production. Magnesium deficiency is common, especially at high altitude.
  • Types of Magnesium: Magnesium citrate is easily absorbed but can have a laxative effect. Magnesium glycinate is gentler on the stomach and well-absorbed. Magnesium threonate may improve cognitive function.
  • Dosage: Start with a low dose (100-200 mg) and gradually increase as needed.
• Calcium: Calcium is essential for bone health and muscle function.
  • Types of Calcium: Calcium carbonate is inexpensive but requires stomach acid for absorption. Calcium citrate is better absorbed, especially for those with low stomach acid.
  • Dosage: Aim for 500-1000 mg per day, depending on your dietary intake.
• Potassium: Potassium is vital for maintaining fluid balance and nerve function.
  • Sources of Potassium: Potassium chloride is a common supplement, but it can have a bitter taste. Potassium citrate is a better-tasting alternative.
  • Dosage: Aim for 2000-3000 mg per day, primarily from food sources like bananas, sweet potatoes, and spinach. Supplement with caution, as high doses can be dangerous.
• Sodium: Sodium is an essential electrolyte that helps regulate fluid balance.
  • Sources of Sodium: Table salt (sodium chloride) is the most common source. Electrolyte drinks and sports gels also contain sodium.
  • Dosage: Adjust sodium intake based on activity level and sweat rate. If you’re physically active, consider adding a pinch of salt to your water or using an electrolyte drink.

Common Mistakes and Pitfalls:

• Ignoring Water Testing: Assuming your water is fine without testing is a common mistake. Always test your water to understand its mineral content.
• Over-Supplementing: Taking too many minerals can be harmful. Start with low doses and gradually increase as needed. Consult with a healthcare professional before taking high doses of any mineral.
• Using Low-Quality Supplements: Choose supplements from reputable brands that use high-quality ingredients. Look for supplements that are third-party tested for purity and potency.
• Not Considering Dietary Intake: Remember that you’re already getting minerals from your diet. Adjust your supplementation based on your dietary intake.
• Dehydration: High altitude can increase your risk of dehydration. Drink plenty of water throughout the day, especially when physically active.

Real-World Scenario:

Imagine you’re a Taos resident who enjoys hiking in the mountains. You’ve been feeling fatigued and experiencing muscle cramps after your hikes. You suspect you might be deficient in minerals.

1. Test your Taos tap water: Order a water test kit from SimpleWater and send in a sample.
2. Analyze the results: The results show that your water is low in magnesium and calcium.
3. Choose a water filter: You decide to install an APEC Water Systems ROES-75 reverse osmosis system with a remineralization stage to remove contaminants and add back essential minerals.
4. Supplement with magnesium: You start taking magnesium glycinate supplements (200 mg per day) to address your magnesium deficiency.
5. Monitor your symptoms: After a few weeks, you notice that your fatigue has decreased and your muscle cramps have subsided.

By taking these steps, you’ve addressed your mineral deficiencies and improved your overall health and well-being.

Living in Taos, New Mexico, offers incredible opportunities for outdoor recreation and a unique lifestyle. However, it’s crucial to be aware of the potential impact of high altitude and water quality on your mineral intake. By testing your water, understanding altitude-related mineral loss, and choosing the right filtration and supplementation strategies, you can optimize your hydration and nutrient intake, ensuring you thrive in this beautiful mountain town. Don’t just assume your water is providing what you need; take control and proactively manage your mineral intake for a healthier, more energetic life in Taos.
