Check the original label ↗Vitamin K is needed for normal blood clotting and for proteins involved in bone health. Labels may contain K1 or different K2 forms, including MK-4 and MK-7. The total amount and combination matter; different names or a larger amount do not establish superiority for everyone.
The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.
The complete declared ingredient amounts
The current table uses a serving of 1 capsule. It declares Vitamin K2 (as Menaquinone-7) (MK-7) 90 mcg; Vitamin K1 1000 mcg; Vitamin K2 (as Menaquinone-4) (MK-4) 5 mg. These are manufacturer label amounts, not a personal dosing instruction.
The comparison detail that changes the decision
The formula separates K1, MK-4 and MK-7; 5 mg MK-4 is 5,000 mcg, so it should not be mistaken for the 90 mcg MK-7 amount. The selected product has 60 labelled servings per container. Matching ingredient form and serving matters more than bottle count.
Excipients, cautions and evidence limits
Other listed ingredients: Microcrystalline Cellulose, Silicon Dioxide, Hypromellose (derived from cellulose) capsule, Vitamin E (mixed tocopherols). Vitamin K can interfere with warfarin and similar vitamin-K-antagonist medicines. Do not add this formula to anticoagulant treatment without the prescriber's review. No independent batch test or exact-formula clinical outcome was verified in this review. Current Indian stock and delivered price remain unverified.
Where might it be useful?
Normal clotting
Adequate vitamin K enables the normal function of clotting proteins.
Bone-related proteins
Vitamin K has a biological role in bone metabolism; this is not proof that every K2 supplement prevents fractures.
What the research can — and cannot — tell us
Supplement studies do not justify treating all K forms and doses as interchangeable. A nutrient’s role in bone health is not equivalent to a demonstrated fracture-prevention effect from this formula. Look at the complete panel, especially when vitamin D or calcium is included.
What deserves your attention?
Vitamin K can interfere with warfarin and similar vitamin-K-antagonist medicines. Do not add this formula to anticoagulant treatment without the prescriber's review.
Suitability comes before strength
Vitamin K can interact seriously with warfarin. People using it should keep intake consistent and discuss any supplement change with their prescriber before starting or stopping it.
Dietary details for this product
Dietary status not confirmed The reviewed current label does not explicitly establish vegan or vegetarian status for the complete formula. A cellulose capsule or dairy-free statement alone is not a whole-formula declaration.
A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive. If you take medicines, have a health condition, are pregnant or are choosing for a child, discuss the full formula with a qualified clinician.
