Natural Factors Vitamin K2 features the vitamin as menaquinone-7 (MK-7), an advanced, fat-soluble form of vitamin K that serves multiple functions in the body. Vitamin K2 plays a role in building strong bones. As a director of calcium, vitamin K2 guides the mineral toward tissues where it is needed, such as bones. Only K2 in the form of MK-7 has been shown to offer 24-hour protection in a single daily dose. Other commercially available subtypes of K2, such as MK-4, only last 4–6 hours in the body and are required in much larger dosages to be effective. The K family consists of a trio of vitamins: K1 (phylloquinone), K2 (menaquinone), and K3, a synthetic form of the vitamin. K3 has been shown to have toxic effects on the liver. While vitamin K1 is easy to obtain from green leafy vegetables, the bacteria in our intestines do not convert enough to K2 to help with osteoporosis. K2 is found in the diet in natto, a fermented soybean food popular in Japan, as well as in butter, meat, egg yolks, and organ meats from animals that are grass-fed rather than grain-fed. As grass-fed animal products are rare nowadays and a taste for natto is difficult to acquire for most Westerners, a vitamin K2 supplement is the best way to ensure you are getting an optimal daily dose of this important nutrient. Most people will have difficulty meeting their daily requirement of vitamin K2 through diet alone. Natural Factors Vitamin K2 provides highly bioavailable MK-7, naturally derived from natto beans, making it easy to get more of this important nutrient.

Natural Factors - Vitamin K2 - 100 mcg - Bonus Size 180 vegetarian capsules

I buy this Natural Factors K2 mk7 as it says its natural sourced from natto bean, so is in the best quality format of ingredient for optimum benefits. small size capsule easy to swallow, no taste. I take this K2 alongside my D3 supplement as K2 facilitates the D3 transporting calcium to the bones, amongst other things. without K2 the dietary calcium may end up in soft tissues or attach to walls of arteries. I am genetically predisposed to D3 metabolism issues and osteoporosis, so this is part of my health maintenance routine as I age. I started taking D3 and K2 (alongside multi-minerals and good diet) from around age 50 to maintain good bone density

Was concerned about arteriosclerosis, so I looked up ways to reduce and or protect against arterial calcification. I found K2 to be beneficial, but is usually found in certain meats and dairy which, because I’m mostly on a plant-based diet, I needed an alternative. After trying my first K2 supplement, I did more reading and found there are at least two types of K2 supplements available, though only one that I believe is more beneficial than the other because of how long each type stay in the body. There is type Mk-4 and Mk-7. According to the National Institutes of Health website, Mk-7 stays in the body for up to three days while Mk-4 stays for mere hours, so I chose type Mk-7. NIH suggests a daily dosage anywhere from 5-600mcg per day. The dosage in this supplement ...

Value for money. Satisfied with the ingredients as it has no bad fillers like maltodextrin. I think it is good quality and I do see a significant reduction in teeth tartar formation probably because Vit K2 helps with avoiding calcium build up in wrong places. Small size capsules. No after taste.
I have gone through numerous bottles of this K2 and you won’t find a better value anywhere than iherb. This is the MK-7 form of K2 which is the most bioavailable form and always costs more than the other forms. It is the best for bone health which is why I’m using it. The tablets are easy to swallow and come packaged very nicely. I’m always amazed how quickly iherb gets its products to me. Great customer service.
I have been taking Natural Factors Vitamin K2, 120 mcg, for a few months now, and I am very pleased with the results! These 60 vegetarian capsules are a fantastic addition to my daily supplement routine.The dosage of 120 mcg per capsule is perfect for my needs, and I appreciate the convenience of having a two-month supply in one bottle. It’s a cost-effective and reliable way to ensure I’m getting the necessary nutrients for my health.
Been taking this after reading and watch videos of vitamin k2’s benefits on our blood health. Will be continuing taking this long term and monitor the test results annually. Quality is great comparing with other more expensive brands. Dosage is more than sufficient and taste is ok. Size would be standard capsule size you wouldn’t have any problem with it.
It's high quality vitamin K2 MK7 from well respected Canadian brand. It has better bio availability than other forms of K2 like MK4 etc. Main benefit of vitamin K2 is to make sure calcium goes to where it belongs (teeth, bones) and not our arteries. Many people take only Vit. D and Calcium and absolutely forget about importance of this vitamin. It's made from Natto bean. Other ingredients are - Vegetarian capsule microcrystalline cellulose, magnesium stearate, silica. The dosage is perfect for daily consuming, previously it was 100mcg, now it's 120mcg which is of course a bonus:) The size of the capsules is quite small and easy to swallow. The have no taste at all.Wish you all good health:)
it gives a good dosage of K2 120mcg, which I chose as I see evident K2 deficiency symptoms like calcification (tartar) in teeth. it is beneficial to take K2 along with D3, as D3 improves calcium absorption and K2 keeps calcium away from where it should not be. the size is swallowable. quality seems good. I have been taking it for a week. will buy again.
I have been using this supplement for a year. The rheology of the blood and, accordingly, the general condition have improved. The supplement is of excellent quality with an optimal set of ingredients. The capsule size is comfortable and easy to swallow. The dosage is sufficient to achieve a therapeutic effect. The benefits are noticeable. The capsule has a neutral taste. I like this product because it is an effective means of maintaining health.
