Pure Encapsulations Vitamin K with D3 is a vegetarian capsule supplement combining a high-potency blend of vitamin K with vitamin D3, in a pack of 60 capsules.

Key Features

• High-potency vitamin K blend: 1,545 micrograms of vitamin K per capsule, combining vitamin K1 (phytomenadione) with two forms of vitamin K2 (MK-7 and MK-4), broader coverage than a single-form vitamin K product.
• Includes vitamin D3: each capsule also provides 1,000 IU (25 micrograms) of vitamin D3 (cholecalciferol), pairing vitamin K with vitamin D in one capsule rather than needing two separate supplements.
• Once-daily vegetarian capsule: one capsule with a meal, in a vegetarian capsule shell (hydroxypropyl methylcellulose).
• Free from common allergens: free from wheat, gluten, egg, peanut, dairy and soy, and made without artificial additives.

Can I take this if I'm on warfarin or another blood-thinning medicine?

Speak to your doctor before taking this product if you're on an anticoagulant (blood-thinning) medicine such as warfarin. Vitamin K plays a central role in blood clotting, and taking a vitamin K supplement can reduce how well these medicines work.

Why does this combine vitamin K with vitamin D3?

Vitamin D contributes to the normal absorption of calcium, while vitamin K contributes to the maintenance of normal bone. Pairing the two in one capsule covers both nutrients in a single daily dose instead of two separate products.

What forms of vitamin K does this contain?

It contains vitamin K1 (phytomenadione), the form most commonly found in leafy green vegetables, together with two forms of vitamin K2: MK-7 (menaquinone-7) and MK-4 (menatetrenone).

Is this suitable for vegetarians?

Yes. The capsule shell is vegetarian (hydroxypropyl methylcellulose), and the formula is free from gluten, dairy, soy, egg and peanut.

Other ingredients: hypoallergenic plant fibre (microcrystalline cellulose); vegetarian capsule shell (hydroxypropyl methylcellulose).

Take 1 capsule daily, with a meal, or as directed by a health professional. Store in a cool, dry place.

Vitamin K plays a key role in blood clotting and can interact with anticoagulant (blood-thinning) medicines such as warfarin, reducing how well they work. If you take an anticoagulant medicine, speak to your doctor before taking this product. If you are pregnant or breastfeeding, have any medical condition, or take any other medication, consult a healthcare professional before use. Keep out of reach of children. Not a substitute for a varied and balanced diet.

Vitamin K and vitamin D3 are generally well tolerated at recommended intakes, and no specific side effects for this product were stated by the manufacturer. Unlike some other fat-soluble vitamins, no tolerable upper intake level has been established for vitamin K, as no adverse effects from high intakes have been identified in humans. This does not apply to people taking anticoagulant medication, who should speak to a doctor before use, as noted above. If you experience a reaction that concerns you, stop taking the product and speak to a pharmacist or doctor.
