6 Facts From Our IV Therapy Toronto Clinic on Vitamin K1


Did you know that our IV Therapy Toronto clinic provides intramuscular shots as a personalized service? This intravenous therapy-related tool might offer beneficial effects.

Alleviating nutritional deficiencies is needed for replenishing cell health and supporting brain health as you age. At the Toronto Functional Medicine Centre, we offer various types of vitamins as injections, such as include vitamin D, vitamin B12 and vitamin K1. But what is vitamin K?

This unique vitamin is one of the main forms of vitamin K, which is necessary for building bones and regulating blood coagulation in cases of cuts, abrasions or injuries. It’s also a cofactor for the carboxylate form of glutamic acid and impacts cellular functioning.

If you’ve recently given birth, the nutrient may be familiar to you; when infants are born, its usually provided to them because vitamin K can’t cut across the placenta in the womb. “Babies are born with very little vitamin K stored in their bodies. Without enough vitamin K, babies cannot make the substances used to form clots, called ‘clotting factors,’” explains the CDC (Centers for Disease Control and Prevention).

Vitamin K consists of several fat-soluble key vitamins, including vitamin K1. K1 is also called phylloquinone, and makes up 90% of the vitamin K content in the human body. It’s significance on the human body is impressive, as our bones and cartilage hold proteins that rely on K1.

Some scientists believe that low levels might be connected to bone health. For instance, the Journal of Orthopaedic Science has highlighted that low vitamin K intake might be associated with knee osteoarthritis.

Vitamin K deficiency is rare in adults because the nutrient is available through dietary intake; also, your intestines naturally create vitamin K. So, why should we still consider its supplementation? Read on to learn about phylloquinone’s prominence on optimal functioning.

6 Facts to Know About Vitamin K1

1. The top compounds of vitamin K include K1 (phylloquinone) and K2 (menaquinone). Phylloquinone is generally “…found in green vegetables and plant chlorophylls, whereas K2 menaquinones are synthesized by bacteria and are primarily found in food where bacteria are part of the production process,” explains an International Journal of Molecular Sciences article.

Quick tip: Consider swapping butter and cheese for olive oil or canola oil. This will help boost your vitamin K intake and perhaps decline your risk of heart disease.

2. In a two-year, double-blind, placebo-controlled trial (on women ages 60 and over), it was shown that phylloquinone – when combined with calcium and vitamin D supplements – has the potential to improve bone mineral content.

3. Phylloquinone might contribute to improved brain function. According to a piece from the Journal of Nutrition and Metabolism, elderly patients with Alzheimer’s disease have low K1 levels. Authors of this article suggest that the vitamin might be linked to enhanced mental performance. “One such study showed that vitamin K1 was associated with better verbal episodic memory performances especially on recall tasks,” authors confirmed to Nutrition and Metabolism.

4. In a study from the American Journal of Clinical Nutrition, it was deemed that low K2 levels might boost hip fracture risks in females. The study was conducted on women over a 10-year period; women with low K1 intake had a 30% chance of getting a hip fracture.

5. Finding a suitable delivery method for phylloquinone is imperative. Its bioavailability “…from green vegetables is lower than from oil or supplements. Also, the phylloquinone content of green vegetables depends on their content in chlorophyll (green pigment), so that outer leaves have more phylloquinone than inner leaves,” confirms Oregon State University. Thus, a K1 intramuscular shot can provide a complete absorption rate without unwanted side effects.

6. A deficiency is rare, though some adults are at risk. This includes people on medications or particular supplements that interact with the injection (i.e. blood thinners, excessive doses of vitamin A and vitamin E); adults with liver disease or damage; and those with malabsorption issues (i.e. inflammatory bowel disease or celiac disease). With that,, a functional medicine provider should be consulted to ensure that vitamin K is suitable for your health condition.
