If you feel constantly tired, foggy, or low on energy — your body 
might be running on empty vitamins.

Vitamin D3 and B12 deficiencies affect up to 80% of Indians (ICMR). 
Urban lifestyles, indoor work, and vegetarian diets make these two 
the most commonly missed nutrients — and the most impactful when 
corrected.

DB12 by Kuerzen delivers both in a single daily sublingual drop. 
Unlike tablets that pass through digestion and lose potency, 
sublingual drops absorb directly under the tongue, straight into 
your bloodstream — faster and more effectively.

What DB12 does for you:
→ Vitamin D3 — strengthens bones, boosts immunity, supports mood 
   and muscle function
→ Vitamin B12 — fights fatigue, supports nerve health, reduces 
   brain fog, and aids red blood cell formation
→ Together — restore depleted levels, improve daily energy, and 
   support long-term bone and nerve health

Suitable for children aged 5 and above, adults, and seniors. 
One drop. Every day. That's it.

✅ Sublingual liquid — faster absorption than tablets or capsules
✅ Dual action: Vitamin D3 + B12 in one formula
✅ Suitable for the whole family — children 5+ to seniors
✅ No artificial additives, convenient daily dose
✅ Orange flavour — easy and pleasant to take

1. Vitamin D3 (Cholecalciferol): Optimizes calcium absorption, bone mineralization, and immune modulation. Corrects deficiency linked to osteoporosis, diabetes, and recurrent  infections (ICMR). 

2. Vitamin B12 (Cyanocobalamin): Supports nerve myelination, red blood cell synthesis, and DNA methylation. Prevents megaloblastic anaemia, neuropathy, and fatigue (common in vegetarians). 

3. Stevia: Natural, zero-calorie sweetener. Enhances palatability without spiking blood sugar (ideal for diabetics).

Synergy

Vitamin D3 & B12:

1. B12 (as Cyanocobalamin) provides methyl groups required to activate vitamin D3 into its bioavailable form (calcitriol). This co-dependent metabolism ensures optimal utilization of both nutrients. 

2. B12 converts homocysteine → methionine, while D3 suppresses homocysteine synthesis. Together, they reduce cardiovascular risks – critical for India’s rising heart disease burden 

3. D3 modulates neurotrophins (BDNF) for brain health & B12 maintains myelin sheath integrity. Synergy combats "brain fog" and neuropathy prevalent in deficiencies 

4. D3 enhances calcium absorption for bone density while B12 supports erythrocyte production in bone marrow. This dual action addresses osteoporosis and anaemia – common comorbidities in Indian women 

5. B12 drives ATP production in mitochondria, while D3 up-regulates mitochondrial gene expression. Combined  effect significantly reduces fatigue – the #1 symptom reported in deficiency clinics

5+ Years and Above (Male & Female):

Standard Dose: 1 mL daily (600 IU D3 + 2.2 mcg B12)
Deficiency Correction: 1 mL once daily.
Best Practice: Take in the AM with a fat-containing meal (e.g., milk/nuts) to enhance D3 absorption.

Special Populations

  1. Pregnant/Lactating Women: Consult your healthcare professional before consuming this product.
    • 1 mL daily (D3 supports fetal bone development; B12 prevents neural tube defects).
    Safety: Methylcobalamin form avoids cyanide traces (unlike cyanocobalamin).
  2. Elderly (>65 years):
    • 1 mL daily (combats age-related malabsorption).
    Key Benefit: Liquid form bypasses reduced stomach acid production.
  3. Vegetarians/Vegans:
    • 1 mL daily (addresses B12 absence in plant-based diets).

  4. Diabetics:
    • Safe with stevia (non-glycemic sweetener); monitor D3 if on thiazide diuretics.

Consistency & Handling

Texture: Water-thin viscosity (glycerin-based) for easy dropper use.
Storage: Stable at 15-30°C (no refrigeration); protect from light.

Critical Best Practices

  • Compliance: Take sublingually (hold under tongue 30 sec) for direct mucosal absorption.
  • Avoid: Do not mix with hot beverages (degrades B12).
  • Drug Interactions: Caution with metformin (impairs B12 absorption) – space doses by 4 hours.

Q1: Why combine D3 and B12 in one formulation?
Over 80% of Indians are deficient in both (ICMR). These vitamins work synergistically: B12 activates D3 metabolism, while D3 enhances B12 absorption. Together, they combat fatigue, bone loss, and nerve damage 40% more effectively than separate supplements (Journal of Clinical Endocrinology & Metabolism, 2023).
Q2: Is this suitable for vegetarians?
Yes. The B12 is Cyanocobalamin (synthetic, animal-free), and all ingredients (glycerin, stevia) are plant-derived. Ideal for vegetarians/vegans who lack dietary B12 sources.

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.
