The Vitamin Shoppe Vitamin K1 100 mcg – Daily Supplement – 100 Tablets

What is Vitamin K1?

Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin naturally found in green leafy vegetables such as spinach, kale, and broccoli. It plays an essential role in the synthesis of proteins involved in blood coagulation and bone metabolism. This supplement provides 100 mcg of vitamin K1 per tablet, a dose that helps meet the recommended intakes for adults according to the European Food Safety Authority (EFSA).

EFSA-approved Benefits

The EFSA has approved two health claims for vitamin K. The first: "Vitamin K contributes to normal blood clotting". The second: "Vitamin K contributes to the maintenance of normal bones". These claims are supported by solid scientific evidence. Incorporating this supplement into your daily routine can be a practical way to ensure an adequate intake, especially if your diet is low in green leafy vegetables or if you have increased needs.

How to take vitamin K1 correctly?

The recommended dose is one tablet daily, preferably with a meal containing fats to optimize its absorption. Each tablet provides 100 mcg of phylloquinone, an amount that approximates the recommended daily intake for adults in the European Union (75-90 mcg for women and 90-120 mcg for men). Do not exceed the indicated dose. If you forget to take a dose, take it as soon as you remember, but do not double the dose the next day.

Possible side effects and contraindications

Vitamin K1 is generally well tolerated at recommended doses. However, people taking anticoagulants such as warfarin should consult their doctor before using this supplement, as vitamin K can interfere with the action of these medications. It is also not recommended for use in pregnant or breastfeeding women without medical supervision. This product is free of gluten, dairy, soy, nuts, preservatives, artificial colors, and flavors, making it suitable for people with food sensitivities.

Frequently Asked Questions about Vitamin K1

What is the difference between vitamin K1 and K2? K1 (phylloquinone) comes from plant sources and is primarily used for blood clotting. K2 (menaquinone) is found in fermented and animal-derived foods and plays a more relevant role in bone and cardiovascular health. Both types contribute to bone maintenance, but K1 is the predominant form in the diet.

Who can benefit from this supplement? People with restrictive diets (vegan or vegetarian), older adults with reduced absorption, or those looking to supplement their intake to maintain normal coagulation and bone health.

Can I take it with other supplements? Yes, as long as you do not exceed the recommended doses. It is common to combine it with vitamin D3 and calcium for comprehensive bone support. Consult a healthcare professional before starting any new supplement regimen.
