Samnel D3 + K2
Calcifediol + Vitamin K2 for Faster, Superior Absorption
Calcifediol (25-OH-D₃) + Vitamin K₂ (MK-7), engineered for adults. 3.2× more effective than standard vitamin D₃, with onset in just 4 hours — and reaches optimal serum levels in 16.8 days versus 68.4 for D₃. Singapore-made, HSA-approved, 60 vegetarian capsules per bottle.
Per capsule:
- Calcifediol (25-OH-D₃) — 10 mcg (1200 IU)
- Vitamin K₂ (MK-7) — 100 mcg
- Vegetarian capsule shell (HPMC) — no artificial colors, fillers, or preservatives
Suggested use: 1 capsule daily, taken with a meal containing healthy fats for optimal absorption.
Bottle size: 60 capsules — a 2-month supply.
- 3.2× more effective than standard vitamin D₃ at raising serum 25(OH)D levels (pooled analysis of 9 randomized controlled trials).
- Onset within 4 hours after oral intake — bypasses hepatic conversion entirely.
- Reaches target in 16.8 days at 100% attainment, versus 68.4 days at only 70% attainment for vitamin D₃.
- K₂ (MK-7) synergy — activates osteocalcin and matrix Gla protein, directing calcium into bones and inhibiting vascular calcification.
- Suitable for hard-to-respond groups — adults with obesity, weak liver function, or malabsorption syndromes who don't respond well to conventional D₃.
How to take: 1 capsule per day with a fat-containing meal. Morning intake is recommended to align with circadian rhythm.
Storage: Below 25 °C in a cool, dry place, away from direct sunlight. Keep out of reach of children.
Cautions: Consult your physician if pregnant, nursing, or taking blood-thinning medication. Do not exceed the recommended daily dose.

calcifediol(25-OH-D₃) + Vitamin K₂ (MK-7). 3× the efficacy of standard D₃. Calcifediol boosts calcium uptake, while K₂ shunts excess calcium to bone to avoid arterial calcification.
Benefits
Calcifediol avoids hepatic conversion needed for ordinary D3 and enters the bloodstream directly. Combined with MK‑7 Vitamin K₂, this high‑potency formula accelerates vitamin D uptake, fortifies bone structure, reinforces immune defenses and maintains healthy muscle performance long-term.

Supporting wellness both physically and immunologically.
