If you work indoors, live in a big city, or rarely catch the morning sun, you’re not alone. Vitamin D deficiency has quietly become the norm in India. The tricky part? It doesn’t always shout. It whispers—fatigue that won’t go away, “mood dips,” odd muscle aches, slower recovery, brittle nails, skin dullness. If that sounds familiar, skim our quick checklist of 14 Signs of Vitamin D Deficiency and come back—we’ll wait.
Now, if you do need a supplement, you could stitch together Vitamin D, Vitamin K₂, and Vitamin B₁₂ separately… or you could simplify with one daily tablet. That’s the promise of OSOAA Vitamin D₃ + K₂ (MK-7) + B₁₂: three essentials that play well together, in a plant-based format.

What you’re actually getting with OSOAA Vitamin D₃ + K₂ (MK-7) + B₁₂
- Vitamin D₃ (≈600 IU) – the form your body uses best; supports immunity, muscles, and calcium absorption.
- Vitamin K₂ (MK-7 ~55 µg) – the “traffic cop” that directs calcium into bones and teeth (not arteries). (Curious why this matters so much? Read the connection between Calcium, Vitamin K2 & vascular calcification.)
- Vitamin B₁₂ (~2.2 µg) – supports energy metabolism and nerves; a thoughtful add-on for vegetarians/vegans.
- Vegan/Vegetarian – D₃ from lichen; small tablets that are easy to swallow.
- Economy – typically 120 tablets per bottle (nice for long-term use).

Why this “D₃ + K₂ + B₁₂” trio works (and who benefits most)
1) D₃ so you actually absorb calcium
Vitamin D₃ increases calcium absorption from food. If you’re also improving your plate with Vitamin D foods—fatty fish, fortified milk/plant milks, UV-mushrooms—D₃ helps you use that calcium.
2) K₂ so calcium goes to the right place
K₂ (especially MK-7) helps activate osteocalcin and matrix Gla protein—proteins that shuttle calcium into bone and keep it out of soft tissues. That’s why “D₃ + K₂” is a classic smart pair. More on the “why” in our explainer: Calcium • K2 • Vascular Calcification.
3) B₁₂ for energy and nerves
If you’re vegetarian/vegan, B₁₂ can be a blind spot. Including it here means one tablet covers immune + bone + energy.
Who benefits most?
- Vegetarians/vegans wanting D₃ + K₂ + B₁₂ without juggling bottles
- Office-goers & students with limited sun time
- Adults 30+ caring about bones, immunity, muscles, and long-term heart health
- Anyone who prefers a single, once-daily routine
Who may need more than this?
- Those with a severe deficiency (often <10 ng/mL) may need a doctor-directed higher IU phase first—then maintain with OSOAA Vitamin D₃ + K₂ (MK-7) + B₁₂. If you’re also optimizing heart-brain support, consider stacking with a quality omega-3—our picks here: Best Fish Oil Supplements on Amazon India.
Real-life feel: what users tend to notice (and what they don’t)
From browsing lots of user stories, a common arc goes like this:
- Weeks 2–4: Subtle energy lift, a bit less afternoon slump; some notice fewer colds.
- Weeks 6–8: Muscle/joint comfort a touch better; “I don’t creak when I stand up.”
- Weeks 8–12: Improvements feel more “set”—especially if diet and sunlight also improved.
What you shouldn’t expect: overnight fixes, or reversal of long-standing issues without broader lifestyle changes. Supplements are helpers, not magicians.
The good, the not-so-good (honest take)
Pros
- One tablet = D₃ + K₂ + B₁₂ (less clutter, better adherence)
- Vegan/vegetarian-friendly
- Thoughtful for Indian lifestyles (low sun + veg diet)
- 120 tabs makes long-term use easy on the wallet
- Small, generally easy to swallow
Cons
- Not a high-dose corrective product (great for daily use; medical guidance needed for aggressive repletion)
- B₁₂ form is often cyanocobalamin in mass-market products (fine for most; methylcobalamin fans may prefer separate B₁₂)
- As with many tablets, additives may be present—check label if you avoid colorants/INS 171
How to take OSOAA Vitamin D₃ + K₂ (MK-7) + B₁₂ for best results
- Dose: 1 tablet daily with a meal that includes some fat (nuts, seeds, ghee, paneer, avocado).
- Timing: Morning or lunch works well for most.
- Stack smart: If you also take calcium, keep total calcium intake sensible and make sure you’re getting K₂ (this product already includes it). If you add omega-3, space it or take together with food—see our fish oil guide.
- Sun + food still matter: Use an easy rhythm—10–20 mins of safe morning sun + vitamin D foods during the week.
