Superior Source Vitamin K1 500 mcg - Bone & Blood Health Support - Vitamin K Supplement Aids Calcium Absorption - 100 Sublingual Dissolving Tablets

Health Benefits of Vitamin K1

Vitamin K1, also known as phylloquinone, plays an essential role in maintaining healthy bones and normal blood coagulation. This fat-soluble vitamin helps activate osteocalcin, a protein that binds calcium to the bone matrix, supporting bone density as you age. It also aids in directing calcium to bones rather than soft tissues, which may contribute to cardiovascular health. Superior Source Vitamin K1 provides 500 mcg per serving in a convenient sublingual tablet that dissolves quickly for efficient absorption.

Recommended Dosage

The typical adult dosage is 500 mcg per day, provided by one sublingual tablet of Superior Source. For optimal absorption, take with a meal containing fat. Consult a healthcare practitioner before starting any new supplement regimen, especially if you are taking anticoagulant medications. This natural health product is licensed under the Natural Health Products Regulations (NPN pending). Always read the label and follow directions for use.

What is Vitamin K1?

Vitamin K1 (phylloquinone) is a fat-soluble vitamin naturally abundant in green leafy vegetables like spinach and kale. It is critical for the synthesis of clotting factors in the liver, promoting normal blood coagulation. As a dietary supplement, Vitamin K1 supports bone metabolism and calcium utilisation. Unlike Vitamin K2, K1 is shorter-acting and primarily involved in coagulation, making it a foundational choice for those seeking targeted support.

How to Choose a Vitamin K1 Supplement

When selecting a Vitamin K1 supplement, consider the form and dosage. Sublingual tablets, like those from Superior Source, offer rapid absorption and are easy to take—ideal for seniors or those with difficulty swallowing. Look for non-GMO and gluten-free labels; this product is both, and vegan-friendly. Superior Source has been producing high-quality supplements in a family-owned facility since 1998.

Vitamin K1 vs K2: Key Differences

While both forms belong to the vitamin K family, Vitamin K1 (phylloquinone) is primarily involved in blood clotting and is shorter-acting. Vitamin K2 (menaquinone) is more bioavailable in bone and vascular tissues. Superior Source Vitamin K1 focuses on the classic K1 form, ideal for supporting coagulation and bone matrix health. For comprehensive support, some combine both forms, but K1 alone is a solid start.

Potential Side Effects & Interactions

Vitamin K1 is generally safe at recommended doses. High doses may interfere with blood-thinning medications like warfarin. If you are on anticoagulant therapy, do not use this product without consulting a healthcare practitioner. Allergic reactions are rare. Keep out of reach of children. If you are pregnant or nursing, consult a healthcare professional before use.
