Understanding the Signs and Solutions for 22 Common Vitamin and Mineral Deficiencies

Summary:

This video explains the importance of 22 essential vitamins and minerals, detailing their functions, symptoms of deficiency, and natural food sources.

Vitamin A: Essential for vision, skin, and immunity. Deficiency causes night blindness, dry skin, and frequent illness. Found in orange and dark green vegetables.
Vitamin B1 (Thiamine): Crucial for energy conversion. Deficiency leads to fatigue, muscle weakness, and neurological issues. Found in whole grains, pork, and legumes.
Vitamin B2 (Riboflavin): Aids in metabolism of fats, drugs, and hormones. Deficiency causes mouth cracks, sore tongue, and light sensitivity. Found in eggs, dairy, and lean meats.
Vitamin B3 (Niacin): Important for energy and nervous system. Severe deficiency can lead to pellagra. Found in chicken, tuna, and mushrooms.
Vitamin B6: Involved in neurotransmitter production. Deficiency impacts mood, causes cracked lips, and weakens immunity. Found in chickpeas, bananas, and poultry.
Vitamin B9 (Folate): Essential for cell growth and DNA synthesis. Crucial for pregnant women to prevent neural tube defects. Found in leafy greens, beans, and citrus fruits.
Vitamin B12: Vital for nervous system and red blood cell production. Common deficiency, especially in vegans, causing fatigue and neurological symptoms. Found in animal products, often requiring supplementation for non-meat-eaters.
Vitamin C: Supports immune system and collagen production. Deficiency leads to easy bruising, bleeding gums, and slow wound healing. Found in citrus fruits, bell peppers, and berries.
Vitamin D: Aids calcium absorption, immunity, and mood. Very common deficiency, especially in winter. Sunlight is the best source, also found in fatty fish, often requiring supplementation.
Vitamin E: Antioxidant protecting cells. Deficiency is rare but causes muscle weakness, vision problems, and weakened immunity. Found in nuts, seeds, spinach, and avocado.
Vitamin K: K1 helps blood clot, K2 directs calcium to bones. Deficiency causes easy bruising and prolonged bleeding. K1 in leafy greens; K2 in fermented foods, egg yolks, and cheese.
Iron: Carries oxygen in blood. Common deficiency, causing extreme fatigue, paleness, and shortness of breath. Heme iron in red meat is best absorbed; plant sources include spinach and lentils.
Calcium: Builds bones and teeth, aids muscle and nerve function. Deficiency causes muscle cramps and bone weakness. Found in dairy, sardines, and fortified plant milks.
Magnesium: Involved in over 300 biochemical reactions, impacting muscle function, sleep, and stress. Common deficiency due to soil depletion, causing muscle cramps, sleep issues, and anxiety. Found in dark chocolate, nuts, seeds, and leafy greens; supplementation is often recommended.
Zinc: Crucial for immune system, wound healing, taste, and smell. Deficiency leads to frequent illness, slow wound healing, and impaired taste/smell. Found in red meat, shellfish, chickpeas, and pumpkin seeds.
Potassium: Regulates fluid balance, muscle contractions, and nerve signals. Most people are deficient. Causes weakness, muscle cramps, and bloating. Found in potatoes, sweet potatoes, spinach, and avocados.
Sodium: Essential for fluid balance, nerve function, and muscle contractions. Deficiency is rare but can occur with excessive sweating or very low-sodium diets, causing headaches and confusion.
Iodine: Needed for thyroid hormones that regulate metabolism. Deficiency causes weight gain, fatigue, and goiter. Found in iodized salt, seaweed, fish, and dairy.
Selenium: Antioxidant, important for thyroid and immune system. Deficiency causes fatigue, brain fog, and thyroid issues. Brazil nuts are an excellent source.
Chromium: Helps regulate blood sugar by enhancing insulin. Deficiency causes blood sugar swings and sugar cravings. Found in broccoli, whole grains, and meat.
Phosphorus: Works with calcium for bones and teeth, and for cell energy/repair. Deficiency is rare but causes weakness and bone pain. Found in meat, dairy, nuts, beans, and whole grains.
