| Vitamin D deficiency solution: Winter sun vs food sources like Milk and Eggs by Pharmacist Naresh |
We often tell ourselves, "It's just the winter weather, everyone feels lazy."
But friends, as a qualified Pharmacist, I want to tell you the scientific truth—this is not just laziness. This could be a warning sign from your body. You might be suffering from a deficiency of the 'Sunshine Vitamin', technically known as Vitamin D.
In months like December and January, nearly 8 out of 10 people in India suffer from this condition. It is often called the 'Silent Epidemic' because most people don't even know they have it. In today’s comprehensive guide on Pharmacist Naresh, we will explore why this happens, how to identify it, and the medically proven ways to fix it.
1. Why Does This Deficiency Happen Mostly in Winter?
You might wonder, "India is a hot country, how can we lack sun?"
The science is simple yet surprising.
- The Angle of the Sun: In winter, the sun moves away from the northern hemisphere. The UVB rays (which make Vitamin D) hit the earth at a slant and become very weak.
- Clothing & Pollution: We cover ourselves in jackets and sweaters. Plus, the heavy fog and smog in cities like Delhi, Mumbai, and North India block whatever little UV rays are left.
- Melanin Factor: Indians naturally have more melanin (darker skin pigment). While melanin protects us from skin cancer, it also acts as a shield that prevents the skin from producing Vitamin D quickly. We need 3 times more sun exposure than a fair-skinned person to make the same amount of Vitamin D.
2. 7 Silent Signs You Are Vitamin D Deficient
Vitamin D is not just a vitamin; it acts like a hormone in the body. If you miss it, your entire system slows down. Check if you have these symptoms:
- Constant Fatigue & Tiredness: Feeling sleepy even after 8-9 hours of good sleep.
- Bone & Back Pain: A dull, aching pain in the lower back, ribs, or joints. Vitamin D helps absorb calcium; without it, bones become fragile.
- Severe Hair Fall: If you see clumps of hair in your comb specifically during winter, it’s a red flag.
- Slow Wound Healing: If small cuts or bruises take forever to heal.
- Frequent Illness: Catching cold, cough, or flu very easily (Low Immunity).
- Depression (Winter Blues): Feeling sad or anxious without any specific reason. Vitamin D regulates mood-lifting chemicals in the brain.
- Muscle Pain: Unexplained muscle cramps or weakness.
3. How Much Vitamin D Do You Actually Need? (Daily Requirement)
According to the Indian Council of Medical Research (ICMR), the daily requirement varies by age:
| Age Group | Daily Requirement (IU) |
|---|---|
| Infants (0-1 year) | 400 IU |
| Children (1-18 years) | 600 IU |
| Adults (19-70 years) | 600 - 800 IU |
| Seniors (70+ years) | 800 - 1000 IU |
Note: If you are already deficient (Level < 20 ng/mL), these maintenance doses won't help. You will need a higher loading dose prescribed by a doctor.
4. Top Food Sources of Vitamin D (Vegetarian & Non-Veg)
Don't rely solely on the sun. Add these power foods to your winter diet chart:
- Egg Yolks: The yellow part is rich in Vitamin D. Don't throw it away!
- Fatty Fish: Salmon, Tuna, and Mackerel are the best natural sources.
- Mushrooms: Especially those grown under UV light. They are the only plant source of Vitamin D.
- Fortified Milk & Cereals: Check the label on your milk packet. Many brands now add Vitamin D to milk.
- Cod Liver Oil: An old but gold remedy. One teaspoon can meet your daily need.
5. Pharmacist Naresh’s Guide to Supplements
If your levels are very low, food alone cannot fix it. Doctors often prescribe supplements. Here is the correct way to take them:
- Choose D3, not D2: Always look for 'Cholecalciferol' (Vitamin D3) on the strip. It is the natural form and absorbs better than D2.
-
The "Fat" Rule: This is the most important tip. Vitamin D is a "Fat-Soluble Vitamin".
- Mistake: Taking it with water on an empty stomach.
- Correct Way: Take it with a glass of full-fat milk, or after a meal that has ghee, butter, or oil. If you take it with water, nearly 40% of the medicine goes to waste!
- Dosage: Common prescription is 60,000 IU once a week for 4 to 8 weeks. Never self-medicate for long periods as high doses can be toxic.
6. The Right Way to Take Sunlight (Sunbathing Rules)
Yes, you can still get Vitamin D from the winter sun if you follow these rules:
- Best Time: Between 11:00 AM and 1:00 PM. (Early morning sun in winter is too weak).
- Duration: 20 to 30 minutes.
- Exposure: Expose as much skin as possible (arms, legs, back). Sitting in the sun wearing a thick jacket is useless.
- No Glass: Sitting inside a closed glass window won't help because glass blocks UVB rays.
7. FAQ: Common Questions Asked by Patients
Q: Can too much Vitamin D be harmful?
A: Yes. Vitamin D toxicity is real. It can cause kidney stones and high calcium levels. Never take supplements daily unless a doctor advises.
Q: Can I stop the supplement once I feel better?
A: You should complete the course (usually 4-8 weeks) and then switch to a maintenance dose or diet to prevent levels from dropping again.
Q: Is Vitamin D deficiency related to weight gain?
A: Studies show that people with low Vitamin D often struggle to lose weight. Correcting the deficiency may help boost metabolism.
Final Verdict
This winter, don't just hide in your blanket and invite illness. If you are feeling lethargic, don't blame your laziness—blame your vitamin levels.
