Micronutrients

Micronutrients are vitamins and minerals that our bodies need in small amounts but are absolutely essential for our overall health. They support every system in the body, including the immune system, hormones, brain function, and energy metabolism. Unlike macronutrients such as protein, carbohydrates, and fats, which provide the calories and energy our bodies need to function, micronutrients do not provide energy directly. Instead, they play crucial roles in metabolism, cellular function, tissue repair, and overall well-being. Without the right balance of micronutrients, our bodies cannot function optimally, and over time, deficiencies can contribute to chronic health issues.

Even though micronutrients are essential, many people today do not get enough. There are several reasons for this:

• Dietary gaps: Modern diets often rely on processed foods that are low in vitamins and minerals. Even fresh produce can be depleted of nutrients due to soil quality and long transportation times.

• Medications: Certain prescription drugs can interfere with nutrient absorption or increase nutrient excretion.

• Lifestyle factors: Stress, poor sleep, alcohol consumption, and overtraining can all increase nutrient needs.

• Health conditions: Chronic illness, digestive disorders, and autoimmune conditions can reduce nutrient absorption or increase requirements.

Key Micronutrients and Their Roles

Vitamin A – supports vision, immune function, and skin health. Deficiency may cause night blindness, dry skin, and frequent infections.

B Vitamins – include B1, B2, B3, B5, B6, B7, B9, B12. Important for energy production, nerve function, and red blood cell formation. Deficiency can lead to fatigue, cognitive issues, anemia, and mood disturbances.

Vitamin C – supports immune function, collagen production, and antioxidant protection. Deficiency may cause slow wound healing, frequent colds, and gum issues.

Vitamin D – regulates calcium absorption, bone health, and immune function. Deficiency can cause fatigue, bone pain, muscle weakness, and mood changes.

Vitamin E – an antioxidant that protects cells. Deficiency may result in nerve problems, muscle weakness, and immune dysfunction.

Vitamin K – essential for blood clotting and bone health. Deficiency can lead to easy bruising and poor bone density.

Calcium – critical for bones, teeth, muscle contraction, and nerve signaling. Low calcium can cause muscle cramps, brittle nails, and osteoporosis.

Magnesium – involved in over 300 enzymatic reactions, including energy production and muscle function. Deficiency may cause fatigue, muscle cramps, anxiety, and sleep problems.

Iron – essential for oxygen transport in the blood. Low iron can cause fatigue, pale skin, dizziness, and shortness of breath.

Zinc – supports the immune system, wound healing, and hormone production. Deficiency can result in slow wound healing, hair loss, and frequent infections.

Selenium – an antioxidant that supports thyroid and immune health. Deficiency may cause fatigue, weak immunity, and cognitive issues.

Iodine – crucial for thyroid hormone production. Deficiency can lead to fatigue, weight gain, and goiter.

Copper, Manganese, Chromium, Molybdenum – trace minerals important for enzymatic functions, metabolism, and antioxidant defense. Deficiency is rare but can affect energy and metabolism.

If you suspect a deficiency, a micronutrient analysis can provide clarity. Labs often offer blood or functional testing to measure vitamin and mineral levels. It is important to consult with a knowledgeable clinician before supplementing so that supplementation is targeted, safe, and effective. This is especially important if you have a diagnosed condition or chronic illness, as optimal nutrient levels support healing and overall health.

Food should always be the foundation. Micronutrients work best when absorbed from nutrient-rich foods. Supplements can support gaps, but do not replace a healthy diet. For example:

Iron: Found in spinach, lentils, beans, and pumpkin seeds. Absorption improves when taken with vitamin C from citrus, peppers, or berries. Avoid taking iron with caffeine or high calcium meals, as it reduces absorption.

Calcium: Found in kale, broccoli, almonds, and fortified plant milks. Pairing with vitamin D enhances absorption.

Magnesium: Found in pumpkin seeds, almonds, spinach, and black beans.

Zinc: Found in pumpkin seeds, chickpeas, cashews, and lentils.

Vitamin B12: Found in animal products and fortified plant foods.

Vitamin D: Sunlight is the best source, but supplementation may be necessary, especially in winter months.

Tips for Maximizing Nutrient Absorption:

• Pair iron with vitamin C sources.

• Avoid consuming caffeine with iron-rich meals.

• Include healthy fats to improve absorption of fat-soluble vitamins A, D, E, and K.

• Rotate nutrient-rich foods to cover a wide spectrum of micronutrients.

Micronutrients are small but mighty. They influence energy, mood, immunity, and long-term health. Making sure your body has the right balance through diet, testing, and targeted supplementation is a cornerstone of optimal health. Especially if you have a chronic illness or autoimmune condition, your body’s nutrient needs are higher, and supporting them is essential for recovery and well-being. By nourishing your body with the right nutrients, you give it the tools it needs to function at its best.
