Daily Dose of D3 or Intermittent Dose? Which is effective?

Vitamin D plays a vital role in bone strength, immunity, and overall wellness. But with various supplementation methods available, a common question arises — should you take Vitamin D3 daily, or is an intermittent high dose more effective?

A recent open-label, randomized 10-week prospective study published on PMC explored exactly this. The study focused on vitamin D-deficient patients and compared the efficacy of daily low doses vs weekly high doses of vitamin D3.

🔍 Key Insights from the Study:

Daily dosing showed a more consistent rise in serum vitamin D levels over time.
Weekly doses, while effective, resulted in fluctuating levels with peaks and dips.
Patients receiving daily low-dose supplementation reported fewer side effects and better long-term tolerance.

✅ What This Means:

For most individuals—especially those with ongoing deficiency—daily vitamin D3 supplementation appears to be more stable and sustainable than large intermittent doses.
