Vitamin K/K2 supplements

Aliness Vitamin K supplements offer a comprehensive range of high-quality dietary supplements designed to support and maintain optimal levels of vitamin K in the body. Vitamin K is a crucial nutrient that plays a vital role in blood clotting, bone health, and cardiovascular support. Aliness, a trusted brand known for its commitment to producing premium nutritional products, has formulated its Vitamin K supplements to provide individuals with a reliable source of this essential vitamin.

How to choose a vitamin K2 supplement

Vitamin K comes in two main forms. K1 is found in green leafy vegetables. K2 is found in fermented foods, especially natto (fermented soya beans), and in smaller amounts in cheese and eggs. Most supplements use K2 as MK-7 (menaquinone-7), which stays in the body longer than other forms.

K2 on its own or with D3?

Vitamin K2 is often combined with vitamin D3, because both are fat-soluble and both are needed for normal bones. If you already take a separate vitamin D supplement, a K2-only product avoids doubling up on D3.

  • K2 only – Vitamin K2 MK-7 Mono FORTE 200 µg capsules from natto, Avitale K2 drops (25 µg and FORTE 50 µg) and Liposol liposomal K2.
  • K2 with D3 – D3 2000 IU with K2 MK-7 capsules, K2 200 µg with D3 2000 IU FORTE capsules, Avitale K2 with D3 drops (including the KIDS version) and Liposol K2 with D3 4000 IU.
  • Pro ADEK® – vitamins A, D, E and K together, as capsules or drops.
  • Oyster Shell Calcium with K2 and D3 – calcium plus both vitamins in one tablet.

Capsules, drops or liposomal?

Capsules give a fixed dose. Drops let you adjust the amount and are easy to give to children (choose the KIDS version and follow its label). Liposomal liquids suit people who prefer to take a liquid.

How much do you need?

The nutrient reference value for vitamin K is 75 µg a day. Most of our K2 products provide 25–200 µg per serving.

How to take it

Take vitamin K2 with a meal that contains some fat, at the same time each day.

What vitamin K does

Vitamin K contributes to normal blood clotting and to the maintenance of normal bones.

Important safety advice

  • If you take warfarin or another blood-thinning medicine, do not take vitamin K supplements without speaking to your doctor first. Vitamin K can affect how these medicines work.
  • Nattokinase, also in this collection, is an enzyme extract, not a source of vitamin K. Speak to your GP before taking it if you take any blood-thinning medicine.
  • Do not exceed the recommended daily dose. Food supplements should not replace a varied, balanced diet.
