Questions and Answers about Life Extension, Super K

Have a Question?

Ask a Question

  • What does the vitamin super K do?

    Super K is a blend of vitamin K1 and two forms of vitamin K2 (MK-4 and MK-7). Vitamin K plays a crucial role in blood clotting, bone health, and cardiovascular health. It helps activate proteins involved in calcium metabolism, supporting strong bones and healthy arteries.

  • What happens if I take vitamin K every day?

    Taking vitamin K daily can help support optimal bone and cardiovascular health. It may help reduce the risk of osteoporosis and arterial calcification, which are associated with aging and certain chronic diseases. However, it's essential to follow the recommended dosage and consult with a healthcare professional, especially if you are taking blood-thinning medications, as vitamin K can interfere with their effectiveness.

  • How do you take Super K?

    Super K is typically taken orally, with or without food, as directed on the product label or by a healthcare professional. The recommended dosage may vary depending on the specific product and individual needs. It's important to follow the instructions carefully and not exceed the recommended dose unless advised by a healthcare provider.

  • What are the benefits of taking K3?

    Vitamin K3, also known as menadione, is a synthetic form of vitamin K that is not commonly found in dietary supplements. It has been used in animal feed and some medical applications, but its use in human supplements is limited due to potential toxicity concerns. The benefits of vitamin K are primarily associated with the natural forms, K1 and K2, which are found in foods and dietary supplements.

  • Who should not take vitamin K3?

    Vitamin K3 (menadione) is not recommended for general use in human supplements due to potential toxicity concerns. It should be avoided by individuals with a history of liver disease, glucose-6-phosphate dehydrogenase (G6PD) deficiency, or those taking certain medications that may interact with vitamin K. Pregnant and breastfeeding women should also avoid vitamin K3 supplements unless specifically advised by a healthcare professional.

  • How much vitamin K3 should I take daily?

    Vitamin K3 (menadione) is not recommended for daily supplementation in humans. The recommended daily intake of vitamin K is based on the natural forms, K1 and K2, which can be obtained through a balanced diet or dietary supplements. The optimal daily dose of vitamin K varies depending on age, sex, and individual health factors, but the general recommended daily allowance (RDA) for adult men is 120 micrograms and for adult women is 90 micrograms. However, it's always best to consult with a healthcare professional for personalized guidance on vitamin K supplementation.
