Vitamin D is essential for bone health, brain function, and muscle movement. Deficiency is common worldwide, with recommended daily amounts varying by age. Sun exposure, diet, and supplements are ways to ensure adequate intake. Symptoms of deficiency include bone and muscle pain, fatigue, and mood swings. Excessive intake can lead to toxicity, causing nausea, weakness, and kidney issues. Most people can safely consume up to 4,000 IU per day. Vitamin D can be obtained through food sources like fatty fish, mushrooms, and fortified products. Regular blood tests can help monitor levels for optimal health.
