Micronutrients Made Simple: Tiny Nutrients, Big Impact
As a functional medicine nutritionist supporting women with chronic illness and thyroid issues, I’m excited to share the power of micronutrients—vitamins and minerals that your body needs in small amounts but with a huge impact on health. Let’s break down the science in an easy-to-understand way and explore how these tiny nutrients keep you thriving.
What Are Micronutrients?
Unlike macronutrients (carbs, proteins, fats) needed in large amounts, micronutrients are required in tiny doses—think milligrams or micrograms. They include vitamins (organic compounds from food) and minerals (inorganic compounds from soil or water). Despite their small size, they’re essential for energy, immunity, strong bones, and more, especially for women managing chronic conditions.
Vitamins: Your Body’s Helpers
Vitamins are like little assistants for your body’s processes. There are 13 vitamins, split into two groups:
Water-soluble vitamins: Dissolve in water, so excess is peed out. You need them regularly since they aren’t stored much. These include B vitamins and vitamin C.
Fat-soluble vitamins: Need dietary fat to be absorbed and can be stored in your body’s fat and liver. These are vitamins A, D, E, and K.
Vitamins are fragile—heat, light, or cooking can damage them—so fresh, minimally processed foods are best.
Water-Soluble Vitamins
B1 (Thiamine): Helps turn food into energy, especially for your brain, heart, and liver. Found in pork, fish, whole grains, and beans. Low levels (rare) can cause fatigue or muscle weakness.
B2 (Riboflavin): Boosts energy and helps break down nutrients. Found in milk, eggs, leafy greens, and beef. Deficiency (rare) may cause tiredness or cracked lips.
B3 (Niacin): Supports energy, cell communication, and antioxidants. Found in poultry, fish, rice, and peanuts. Severe lack (very rare) causes pellagra (skin issues, diarrhea).
B5 (Pantothenic Acid): Helps make energy and fats. Found in eggs, broccoli, nuts, and fish. Deficiency is uncommon due to its wide availability.
B6 (Pyridoxine): Key for protein use and over 100 body reactions. Found in bananas, chickpeas, and poultry. Low levels can occur with inflammation or heavy alcohol use.
B7 (Biotin): Supports metabolism and cell signaling. Found in egg yolks, salmon, and nuts. Deficiency is rare but can affect hair or skin.
B9 (Folate): Vital for making DNA and red blood cells, especially during pregnancy to prevent birth defects. Found in leafy greens, legumes, and citrus. Low folate can cause anemia.
B12 (Cobalamin): Needed for nerves, blood cells, and DNA. Found only in animal foods like fish, eggs, and dairy. Vegans or those with poor digestion may lack it, causing fatigue or anemia.
Vitamin C: A powerful antioxidant that boosts immunity, builds collagen, and helps absorb iron. Found in oranges, bell peppers, and kiwi. Lack of it (scurvy, rare today) causes weak tissues and slow healing.
Fat-Soluble Vitamins
These need fat to be absorbed and are stored in your body, so deficiencies are rare but can happen if fat digestion is impaired (common in some chronic conditions).
Vitamin A: Supports vision, skin, and immunity. Found as retinol in liver and eggs, or as beta-carotene (a precursor) in carrots and squash. Beta-carotene also fights cell damage.
Vitamin D: Acts like a hormone, aiding bone health by helping absorb calcium and reducing inflammation. Found in fatty fish, egg yolks, or made by your skin in sunlight. Low levels can weaken bones.
Vitamin E: An antioxidant protecting cells, especially fats, from damage. Found in almonds, sunflower seeds, and spinach. Deficiency is rare but can affect nerves.
Vitamin K: Helps blood clot and strengthens bones. Found as K1 in leafy greens and K2 in fermented foods. Low levels (rare) can cause bleeding issues.
Why Micronutrients Matter
Micronutrients are like the spark plugs in your body’s engine. They:
Turn food into energy (B vitamins).
Protect cells from damage (vitamins C, E).
Build strong bones and tissues (vitamins D, K, folate).
Support immunity (vitamins A, C, D).
Keep nerves and muscles working (B vitamins, minerals).
For women with thyroid issues or chronic illness, micronutrients are crucial to reduce inflammation, boost energy, and support hormone balance. A diet low in micronutrients can lead to fatigue, weak immunity, or worse—especially if digestion is compromised.
Nutrition Tip
Eat a rainbow of whole foods daily to get your micronutrients. Try a spinach salad with salmon and avocado for vitamins A, D, and E, or snack on oranges and bell peppers for vitamin C. Cooking gently (steaming, not overboiling) preserves vitamins. If you avoid animal foods or have digestive issues, talk to a nutritionist about your B12 or vitamin D needs.
A Holistic Approach
Micronutrients work with macronutrients to keep your body in balance. For women with chronic conditions, a nutrient-dense diet can transform energy and health. Stay tuned for more on tailoring nutrition to your unique needs!
