1. What Causes Nutrient Deficiencies?

Nutrient deficiencies can happen even if you eat a well-balanced diet. Here’s why:

1.1 Poor Diet & Processed Foods

🚫 Processed and fast foods are often low in essential vitamins and minerals while being high in sugar, salt, and unhealthy fats.

💡 Solution: Eat whole, nutrient-dense foods like fruits, vegetables, lean proteins, and healthy fats.

---

1.2 Soil Depletion & Lower Nutrient Quality in Foods

🚜 Modern farming practices have depleted the soil of key minerals, meaning even fresh produce may have lower nutrient content than it did decades ago.

💡 Solution: Choose organic, locally sourced, and seasonal foods whenever possible.

---

1.3 Digestive Issues & Poor Absorption

🦠 Gut health plays a major role in nutrient absorption. Conditions like IBS, leaky gut, and chronic inflammation can reduce how well your body absorbs vitamins and minerals.

💡 Solution: Take prebiotics & probiotics like Elyxa Gut to support digestion and nutrient absorption.

---

1.4 Stress & Hormonal Imbalances

😓 Chronic stress increases cortisol (the stress hormone), which depletes magnesium, B vitamins, and vitamin C—leading to fatigue, anxiety, and weakened immunity.

💡 Solution: Support stress resilience with magnesium, adaptogens, and a nutrient-dense diet.

---

1.5 Medications That Deplete Nutrients

💊 Certain medications can interfere with nutrient absorption, including:

• Antibiotics (kill gut bacteria that help with vitamin synthesis)
• Birth control pills (deplete B vitamins, magnesium, and zinc)
• Antacids & PPIs (reduce stomach acid, affecting B12 and mineral absorption)

💡 Solution: If you’re on long-term medication, consider targeted supplements to replace lost nutrients.
