The problem most people don't know they have
Despite Singapore's year-round sunshine, Vitamin D deficiency is widespread. A study of healthy adults in Singapore found that approximately 42% were Vitamin D deficient — because sunscreen use, indoor working environments, and clothing habits all significantly reduce how much Vitamin D the skin actually produces from sun exposure (NUS Yong Loo Lin School of Medicine, 2016).
What makes this harder to fix than it looks: Vitamin D increases your body's ability to absorb calcium. But calcium absorbed without adequate Vitamin K2 doesn't automatically go where it should. Without K2, calcium can accumulate in arteries and soft tissue rather than being directed into bone.
Vitamin D3 and Vitamin K2 MK-7 work as a pair. Taking them together addresses both sides of the calcium equation.

How D3 and K2 MK-7 work together
Vitamin D3 (as Cholecalciferol) — 1,000 IU
D3 is the form your skin produces from sunlight, and the form with the strongest evidence for raising blood Vitamin D levels — significantly more effective than D2 at equivalent doses. It supports intestinal calcium absorption, immune regulation, and muscle function. 1,000 IU is a well-established daily maintenance dose for adults with limited sun exposure.

Vitamin K2 (as Menaquinone-7, MK-7) — 100mcg
MK-7 is the preferred form of K2 for daily supplementation. Unlike MK-4, which clears the body within hours, MK-7 has a half-life of approximately 72 hours — meaning once-daily dosing keeps it consistently active. K2 activates two key proteins: osteocalcin, which directs calcium into bone tissue, and Matrix Gla Protein (MGP), which helps prevent calcium from depositing in arterial walls.

What you get per serving

Vitamin D3 (as Cholecalciferol) | 1,000 IU | 125% Daily Value
Vitamin K2 (as Menaquinone-7) | 100mcg | 83% Daily Value
Serving size: 1 Vegetable Capsule | Servings per container: 60 | Supply: 60 days | Made in Singapore

Key Benefits
Supports bone and teeth health
D3 ensures calcium is absorbed from your diet. K2 MK-7 then activates osteocalcin, directing that absorbed calcium into bone matrix where it contributes to density and structural strength. Current evidence supports this pairing for maintaining bone health — particularly in adults 40 and above.
Supports heart health
K2 MK-7 activates Matrix Gla Protein (MGP), which research associates with reduced arterial calcification. Observational studies show that people with higher levels of carboxylated MGP — reflecting adequate K2 status — consistently have lower arterial calcification scores. Note: the cardiovascular evidence is strongest from observational data; large randomised trial evidence in this specific area is still developing.
Supports immune system health
Vitamin D3 plays a well-established role in immune regulation, including the activation of T-cells and the body's antimicrobial defences. Deficiency is associated with increased susceptibility to infection and reduced immune resilience.

Directions of Use
Take 1 capsule daily with any meal containing healthy fats to enhance absorption, as Vitamin D3 and Vitamin K2 are fat-soluble nutrients. Or take as directed by a healthcare professional. Store in a cool and dry place.
Caution: Individuals with medical conditions should consult a healthcare professional before use. If you are on Warfarin or any anticoagulant medication, do not take this product without first consulting your doctor — Vitamin K2 can affect anticoagulation control.
Who is this suitable for?

  • Adults working indoors with limited daily sun exposure

  • Adults 40 and above looking to proactively support bone density and heart health

  • Anyone already taking a Vitamin D supplement who wants to ensure calcium is being directed properly

  • Those looking to cover bone, immune, and heart health in a single daily capsule

Not suitable for individuals on Warfarin or anticoagulant therapy without prior medical consultation.
Why Estalife?
This formula uses Cholecalciferol (D3, not D2) and Menaquinone-7 (MK-7, not MK-4) — the forms with the strongest human evidence and best bioavailability for daily supplementation. Made in our own NSF GMP-certified factory in Ang Mo Kio, Singapore. No middlemen. Every batch manufactured and tested here, sold directly to you.
Frequently Asked Questions
Why D3 and not D2?
D3 is the form your skin naturally produces and is significantly more effective at raising blood Vitamin D levels than D2 at equivalent doses. D3 is the standard form used in clinical research on Vitamin D supplementation.
Why MK-7 and not MK-4?
MK-7 has a half-life of approximately 72 hours compared to roughly 8 hours for MK-4. This means once-daily dosing with MK-7 keeps it consistently active in the body throughout the day, whereas MK-4 clears too quickly for a single daily dose to maintain stable levels.
Do I need to take this with food?
Yes. Both D3 and K2 are fat-soluble — they need dietary fat to be absorbed properly. Take with any meal that contains healthy fats: eggs, avocado, nuts, oily fish, or food cooked in oil.
Can I take this if I am on Warfarin?
No, not without first consulting your prescribing doctor. Vitamin K2 affects the same pathway that Warfarin acts on and can alter anticoagulation control. Always check with your doctor before adding any Vitamin K supplement if you are on blood thinners.
