Frequently Asked Questions
1. What are the signs of Vitamin D3 and B12 deficiency?
Common signs include constant fatigue, low energy, bone or joint pain, hair fall, and reduced immunity. Over 80% of Indians are deficient in both vitamins (ICMR), often due to limited sun exposure and dietary gaps — DB12 is formulated to help correct both.
2. Why does DB12 combine D3 and B12 in one formulation?
These vitamins work synergistically — B12 helps activate D3 into its usable form, while D3 supports B12 utilization. Together, DB12 helps combat fatigue, bone loss, and nerve-related symptoms more effectively than taking each separately.
3. Can DB12 help with hair fall?
Vitamin D3 and B12 deficiency is commonly linked to hair thinning and hair fall. By correcting these deficiencies, DB12 supports the underlying nutritional cause — though hair fall can have multiple causes, so consult a doctor if it persists.
4. Can children take DB12 drops?
Yes. DB12 is suitable for children aged 5 and above, as well as adults and seniors, in the standard 1 mL daily dose. Consult a pediatrician for children with specific health conditions.
5. How should I take DB12 drops?
Place 1 mL under the tongue, hold for 30 seconds, then swallow. Take in the morning with a fat-containing food like milk or nuts to enhance D3 absorption.
6. How soon will I see results with DB12?
Blood levels typically improve within 4–6 weeks. Energy and bone-related benefits may take 8–12 weeks of consistent use.
7. Why liquid form over tablets?
DB12's liquid format offers significantly higher bioavailability than tablets, since sublingual absorption bypasses gut issues — making it especially effective for those with IBS, low stomach acid, or post-bariatric surgery needs.
8. Can diabetics use DB12?
Yes. DB12 is sweetened with stevia, a zero-glycemic sweetener, and Vitamin D3 may even support improved insulin sensitivity.
9. Is the DB12 dose safe for seniors?
Yes. The liquid format bypasses age-related gut absorption issues, and DB12's dosage aligns with ICMR guidelines for seniors without added kidney strain.
10. Can pregnant or breastfeeding women use DB12?
Consult your healthcare provider before use during pregnancy or breastfeeding.
11. Can I take DB12 with other medications?
Generally safe, but space doses 4 hours apart from metformin, as it can reduce B12 absorption. Avoid combining with steroids, which may lower D3 efficacy. Consult your doctor if on chronic medication.
12. How should I store the DB12 bottle?
Keep at room temperature (15–30°C), away from direct light. No refrigeration needed — shelf-stable for 24 months.
13. Why should I trust DB12?
DB12 combines Vitamin D3 and B12 in stable, well-researched forms, dosed to match ICMR and NIN guidelines for Indian adults. It's manufactured in FSSAI-approved, GMP-certified facilities, fully ingredient-disclosed, and formulated specifically for correcting India's widespread D3/B12 deficiency.
