BulkSupplements.com Vitamin K1 Powder - Vitamin K1 Supplement for Bone and Heart Health Support - Gluten-free, 10 mg per Serving, 100 g (3.5 oz)

What Is Vitamin K1?

Phylloquinone, better known as Vitamin K1, is a fat-soluble vitamin essential for blood clotting and bone metabolism. You'll find it naturally in green leafy vegetables like spinach and kale, but this synthetic powder provides a concentrated dose for convenient supplementation. By activating proteins that regulate coagulation and calcium, Vitamin K1 is a foundational nutrient for your body's everyday functions.

Health Benefits of Vitamin K1

Vitamin K1 supports several vital processes. Its primary role is in normal blood clotting, helping the liver produce clotting factors. For bone health, it aids in carboxylating osteocalcin, a protein that binds calcium to the bone matrix, thereby maintaining density and strength.

Cardiovascular benefits are also emerging: Vitamin K1 activates matrix Gla-protein (MGP) to prevent calcium deposits in arteries, promoting arterial flexibility. Although more research is needed, adequate Vitamin K intake is considered beneficial for heart health.

• Blood Clotting: Essential for activation of clotting factors.
• Bone Density: Helps bind calcium to bones.
• Heart Health: May maintain arterial elasticity.

Recommended Dosage

The recommended dietary allowance for adult Vitamin K is about 90-120 mcg daily. This product supplies 10 mg (10,000 mcg) per serving—a much higher dose often used in research or under professional guidance. Because Vitamin K is fat-soluble, taking it with a meal that contains fat (e.g., avocado, olive oil) improves absorption. Always consult a health care provider before exceeding standard intakes.

How to Use This Powder

Measure accurately using the included scoop or a milligram scale. Start with a small amount and increase gradually. Mix the powder into water, juice, or a smoothie—its neutral taste blends easily without altering flavour. Store in a cool, dry place away from sunlight to maintain potency.

Potential Side Effects & Interactions

Vitamin K1 is generally safe and well-tolerated. High doses may occasionally cause mild digestive upset. The main concern is interaction with anticoagulants like warfarin (Coumadin); Vitamin K can counter their effects, so consistent intake and medical monitoring are crucial. Antibiotics may reduce gut production of Vitamin K, and some anticonvulsants may also interact. Those with malabsorption disorders (e.g., cystic fibrosis, Crohn's disease) may need higher doses but only under supervision. Always inform your health care provider about any supplements you take.

Frequently Asked Questions

Can I take Vitamin K1 with Vitamin D?

Yes, they work synergistically for bone health: Vitamin D enhances calcium absorption, while Vitamin K directs calcium to the bones, reducing soft tissue calcification.

Is this Vitamin K1 vegan?

Vitamin K1 is naturally plant-derived, and this powder is suitable for vegan and vegetarian diets. Always check the label for any additional ingredients.

How long does it take to see benefits?

Effects on clotting and bone health may not be immediate. Consistent supplementation over weeks to months supports long-term outcomes; results vary by individual health and diet.

Can I take this on an empty stomach?

It can be taken on an empty stomach, but absorption improves with a meal containing fat. For best results, consume with food.
