Introduction

Vitamin K is one of the unfamiliar forms of supplements for people.

Research on this relative newcomer nutrition scene identified in the 1920s is still limited. It was assumed, for years, that its principal benefit was its involvement in blood clotting – the “K” stands for “coagulation” in German. 

However, as more studies say, it may be a significant factor in calcium deposit, strengthening of the bone, and many more. After knowing all the benefits, most people start including the best vitamin K2 supplements in Australia in their diet. 

Although the nutrient occurs in various forms, K2 is generally known as the most vital nutrient for supplementation. So, read the article and check out our list of the best vitamin K2 supplements in Australia.

Let's take a deep dive into these 7 best Vitamin K2 Supplements in Australia

Tips for choosing the right vitamin K2 supplements for you

The factors to consider while buying the best vitamin k2 supplements in Australia are:

Menaquinone compounds

Vitamin K2 comes in various forms, each with its characteristics. Even still, MK-7 and MK-4 are known as the most crucial. The MK-7 chemical promotes strong bones by increasing bone mineral density. MK-4 aids in the formation of collagen and carboxylation, a process that influences the quantity of calcium in your bones. When looking for vitamin K2 pills, look for ones that contain a variety of menaquinone compounds, though any supplement that contains MK-4 and MK-7 will suffice.

Concentration

Vitamin K2 supplements are available in the following amounts: 65 mcg, 100 mcg, and 120 mcg (MK7), as well as greater levels up to 1300 mcg (MK4). The recommended daily amount of vitamin K2 of type MK7 (120 mcg) is the most effective due to its ease of absorption and bioavailability. Look for the concentration of K2 per capsule. 

Ingredient

If you have any dietary limitations, ensure your K2 vitamin supplement matches those requirements. Check the list of ingredients. Although maximum K2 supplements are vegan or vegetarian, some may contain animal byproducts. So, examine the ingredient list for its content. Ensure that you are not allergic to any one of them. Consider a supplement that has no GMO and is pure.

Taste and smell

K2 vitamin supplements may have an unpleasant taste or odor, which many people dislike. Although most K2 supplements are pleasant to drink, some are unusually bitter, making them difficult to take daily. It is a good idea to take a K2 vitamin supplement with a bearable flavor and scent.

Bottle

When purchasing the best vitamin K2 supplement in Australia, it is critical to examine the product’s bottle. Vitamin K2 is light-sensitive, so the bottle should be dark or opaque to keep the capsules from being exposed to light.

Several capsules

Vitamin K2 is available in tablet form. The suggested daily dose is one capsule each day, either first thing in the morning or during one of your main meals. The number of capsules in each bottle varies from 60 to 90 to 100 units. Buy a bottle that has a maximum number of pills matching the price.

Certified

Make sure your supplement is third-party verified. Third-party supplements tested in a lab for purity. It ensures that they contain what they claim and do not contain high-risk, common contaminants. The best vitamin K2 supplements in Australia come with ConsumerLabs, NSF, and USP third-party certifications.

Reviews

When you take a K2 vitamin supplement, you may have adverse effects, just as with any other supplement. It is best to choose a supplement that doesn’t have many side effects mentioned in reviews. A review also helps find out the taste, smell, and any problem related to the supplement.

Benefits of using vitamin K2 supplements

Here are some major benefits of taking the best vitamin K2 supplements in Australia.

Heart health

Vitamin K-2 may help reduce the risk of heart disease and enhance overall heart health. According to a study, K-2 activates a protein that inhibits calcium deposits from accumulating in blood vessel walls. The study also suggested a diet rich in natural vitamin K2 could reduce the incidence of coronary heart disease.

Improve dental health

Vitamin K2 strengthens teeth in the same way as it strengthens bones. This is because the vitamin aids calcium absorption by the teeth and activates dentin, which aids in the structure and health of the teeth.

Reduce inflammation

The possibilities of inflammation increase when the body has a low level of vitamin K and a high level of cytokines. Vitamin K2 lowers the body’s cytokine levels. Vitamin K2 supplementation is ideal for persons with inflammatory conditions such as Lupus, Crohn’s Disease, and diabetes.

Enhance exercise performance

During exercise, bones release osteocalcin, which appears to transmit messages to muscles to help them cope with increasing energy needs. Vitamin K2 protein permits skeletal muscle to utilize energy during exercise and increase workout efficiency and potential performance.

Bone health

Taking the best vitamin K2 supplements in Australia promotes a healthy bone mineral density by carboxylate osteocalcin, a protein that binds calcium to bones.

In a study, 29 postmenopausal females with hip or vertebral compression fractures were given MK-4 supplements to see how they would react. The researchers found that consuming 5 milligrams of MK-4 daily lowered the level of undercarboxylated osteocalcin to levels “typical of healthy, premenopausal women.”

Anxiety and depression

High blood sugar levels can put a person at risk for depression, anxiety, and cognitive impairment. Effects of vitamin K-2 were studied with metabolic syndrome, high blood glucose levels, signs of anxiety, and depression. The treatment stabilized the blood glucose, reduced anxiety and depression symptoms after ten weeks. 

Increase testosterone level

In the male testis, vitamin K2 MK-4 produces steroid hormones. In a study, a diet containing 75 mg/kg MK-4 increased testosterone level compared to a control diet.

Side-effects of using Vitamin K2 Supplements

Oral Vitamin K2 has rare side effects when taken at prescribed levels. Some of them are:

• Decreased appetite
• Muscle stiffness
• Decreased movement or activity
• Irritability

If you have any such symptoms, please consult your doctor or local pharma.

Recommended Dosage of Vitamin K2 Supplements

The recommended daily consumption of vitamin K from food and supplements are listed below. Maximum people consume adequate vitamin K2 through their foods.

Conclusion

Vitamin K is a set of nutrients classified into K1 and K2 vitamins.

Vitamin K1 aids in blood clotting, while vitamin K2 promotes bone and heart function. More research on the roles of vitamin K subtypes is needed, however.

Some scientists believe that people at risk of heart disease should take vitamin K2 supplements daily. Others argue that we need further research before any definite suggestions.

Vitamin K, on the other hand, is essential for physiological function. Make sure you include enough vitamin K1 and K2 in your diet to keep your health in check.
