Love this stuff!!!

Apart from those times when you haven't got enough greens into you and you feel deficient in K... this works really well if you've had a late night coffee (tea or even chocolate are also stimulants) and can't go to sleep. It seems to excrete the cafeine (or other stimulant) in the urine and you drift off to sleep naturally. This is the synthetic version of K2 (MK4) so I've switched to the MK7 (natural) version. Unfortunately the natural version is only 100 ug (50 times less) and not as potent as this one. Take this and you'll feel the difference a lot more easily. The first effect everyone seems to notice is stronger teeth and the fact that the plaque on the back of your teeth is no longer there. It's malformed calcium and is now being absorbed into your bones (which includes the teeth). If you want to convince yourself or someone else that K2 works try this version. :-)

Great for bones and brain function

I started taking Vit K2 for bone health. This brand has no particular taste, small in size and easy to swallow. It is in powder form in a gelatin capsule. Good quality ingredients. I take one capsule in the morning and one at night with meals together with Vit D3, Magnesium and Calcium. The most immediate benefit I can feel is that I can focus better with my tasks, less brain fog. As an added bonus, my teeth feels a lot less sensitive since I started taking this.

Price corresponds to quality

Vitamin K2 is important in the body's use of calcium. I take half capsule a day only together with calcium to help build bones and to inhibit blood vessel calcification. It is also good for skin health and bone metabolism, it promotes proper brain function and heart health. The capsules are small and yellow, Carlson labs is a good solid brand.

Perfect for health

My doctor recommended that I buy this product, so I bought it. I was happy with the price and size of the package. I don't really know what it was supposed to do, so I can't tell if it was potent, but the pills were gentle on the stomach.

The only vitamin K I use

Highest quality k2 I've found anywhere. Ingredients I'm looking for. Dosage I need. The bottle is proper size for product contained. Benefits those who are highly allergic and sensitive that do not eat their veggies. I break the capsules open to split. No funky taste. The only vitamin k supplement I use.

The best K2

This is a dry, oil-free vitamin K2 which is more useful with fat malabsorption problems. It is also the body-preferred form of menaquinone-4 (MK-4) and the capsule size is quite small. The dose is an efficient 5 mg and the purity is great. This form of K2 is synthetic, but avoids any problems of soya contamination as with MK-7. Great for bones, teeth, circulation and keeping calcium in the right places. I take it in a synergistic combination with magnesium taurate, real food vitamin C, vitamin B6, and amino acids such as L- lysine.

One of the better supplements available in the world

Vitamin K2 was discovered by Weston A. Price, a pioneering American dentist and researcher. In the 1930s, he travelled the world studying isolated populations with excellent dental health and robust physical development. He observed that their diets contained a mysterious fat-soluble nutrient, which he termed "Activator X." Price found that this substance worked synergistically with vitamins A and D to support bone development, dental health, and overall immunity. Decades later, Activator X was chemically identified as a form of vitamin K2 (specifically the menaquinone-4 form). This formulation provides a higher dosage of vitamin K2 than most other providers. I haven't had cavities in the years since I've been taking it.
