Vitamin D plays a crucial role in your overall well-being. From supporting strong bones to boosting your immune system, ensuring you have adequate levels is essential.
Why Is Vitamin D Important? Helps calcium reach your bones for strength and density.
-
Supports the immune system in fighting infections.
-
Adequate levels increase calcium absorption in bones from 10-15% (low levels) to 30-40%.
-
Low vitamin D levels can lead to hypocalcemia (low blood calcium) and a higher risk of autoimmune diseases like multiple sclerosis, lupus, and type 1 diabetes.
Key Benefits of Vitamin D
✅ Stronger bones through improved calcium absorption.
✅ Enhanced immune system response, helping to fight off illnesses.
✅ Mood support – studies link low vitamin D to higher rates of depression.
Possible Side Effects
While rare, excessive vitamin D intake can lead to toxicity:
-
Vitamin D toxicity (hypervitaminosis D) occurs with prolonged high doses (60,000 IU per day for several months).
-
Always follow recommended guidelines and consult your healthcare provider.
How Much Vitamin D Do You Need?
The recommended daily intake varies by age:
-
Infants (0-6 months): 1,000 IU (25 mcg)
-
Babies (7-12 months): 1,500 IU (38 mcg)
-
Toddlers (1-3 years): 2,500 IU (63 mcg)
-
Children (4-8 years): 3,000 IU (75 mcg)
-
Older children & adults (9+ years): 4,000 IU (100 mcg)
💡 Tip: Many experts suggest these recommendations may be too low. Testing your vitamin D levels can help determine the optimal dosage for you.
