Buying Guide

Some factors should be considered when acquiring the best vitamin K supplement.

First of all, there are two classes of vitamin K, K1 and K2, which should be distinguished. There are two main forms: vitamin K1, also known as phylloquinone, and vitamin K2, also known as menaquinone. Vitamin K1 is found in green, leafy vegetables and is involved in the clotting of the blood, while vitamin K2 is obtained from animal products and foods that have been fermented, and it is concerned with the formation of bones. Depending on your personal requirements, you may wish to select a supplement that incorporates one or both kinds of vitamin K.

Secondly, consider the dosage of the supplement that you are taking or intend to take. It should be noted that doses of vitamin K may also depend on age, health conditions, and other factors. That is why it is better to consult your doctor to define the right dosage for you. Ensure you get a supplement that has the right amount of the daily requirement in one serving.

It is also important to know the quality and purity of the supplement as well as the concentration of the active ingredients. You should choose products that have been tested for purity and concentration by a third party and produced by a company that complies with GMP.

Last but not least, it is wise to cast an eye on any extras in the supplement. In some cases, products may include flow agents, lubricants or substances that may cause an allergic reaction. Always check the label and select this product without any component that you are sensitive to or that may induce undesired side effects.

To conclude, when opting for a vitamin K supplement, these factors should be taken into consideration: the type of vitamin K, the quantity, the quality and purity, and the presence of other components. Thus, considering these factors enables one to make the right decision regarding the appropriate supplement to take so as to improve one’s health.
