Life ExtensionSuper K with Advanced K2 Complex Softgels,90 Count

Return customer, great product, now improved.I have been using this full spectrum Super K vitamin for well over a year now, after experimenting with others, and it has become my preferred formula and brand. The improvement comes from the K7 formula. It used to be 200 mcg of the K7 menaqionone and now is 100 mcg. The former 200 mcg of menaquinone (the form used by most brands) was fine, but included the CIS & TRANS forms. While TRANS is superior to CIS there was no way to tell what percent of the more active, bio-available TRANS menaquinone was included. But now, with an updated mfg. process, only the TRANS form is present, providing 100% of the TRANS form, eliminating the unnecessary CIS form. Thus, only 100 mcg is required. The product is now purer and you get more for your money for an already superior Full Spectrum Vitamin K supplement. Highly recommended for quality and dosage, Vitamin K2 is necessary (among other benefits) for keeping calcium out of arteries (which can lead to hardening of same) and other unwanted organs and for transporting it into bones where it belongs. Works well in a symbiotic relationship with D3 which is why you'll find many supplement suppliers combining them in a single tablet or capsule. This is good as far as it goes, but they often skimp a tad on the K2 dosage, the combination of K4 and K7 offered (if indeed they provide both of them), and you can't be sure how much of their K7 from menaquinone is in the TRANS form, for as stated above most K7 sold today as menaquinone is a blend of CIS & TRANS forms with the TRANS being the much lower percentage (making the percentage of the TRANS K7 only the supplier's guess).Life Extension provides not only a full spectrum Vitamin K supplement (many don't), but with this improved formula is a solid choice and worth every penny.

Life Extension's Super K with Advanced K2 is the best formulation around. Vitamin K2 is very important. It removes calcium from your arteries for optimum blood flow! Each and every day, your blood pumps through 100,000 miles of arteries, veins and capillaries. The diameter of your veins and arteries affects the rate of blood flow and the amount of pressure needed to pass through your arteries. The bigger the opening, the less pressure is needed. So what do you think happens when those blood vessels get lined with layers and layers of calcium plaque deposits? The pathway narrows and your blood literally has to squeeze through those arteries and veins—causing your blood pressure to skyrocket.The right kind of Vitamin K2, a simple nutrient, can quickly help remove calcium from your blood vessels and keep them wide open for healthy blood flow. You probably know of the more common vitamin K1. This is the form of vitamin K that's readily available in green vegetables. And it's very important for normal blood clotting, but vitamin K2—also known as menaquinone—is very different. Vitamin K2 is essential for your cardiovascular health because of its amazing ability to utilize calcium. In fact, vitamin K2 acts like a shuttle bus. It moves unwanted calcium out of your arteries and delivers that calcium to your bones where it's needed for bone health! Numerous studies show the amazing power of vitamin K2. For example, The prestigious Rotterdam Study published in the Journal of Nutrition shows patients with the highest levels of vitamin K2 experience better cardiovascular health. An additional five-year follow-up study of more than 4,400 elderly patients confirmed the original findings: The more vitamin K2 in your body, the healthier your arteries!But before you go taking any Vitamin K2, please know this - Not all vitamin K2 products are alike. In fact, most of the supplements on the market are downright misleading. Here's why - Vitamin K2 contains many subtypes including MK-1 through MK-13. But without a doubt the subtype of vitamin K2 you need for healthy blood pressure is MK-7. This is the actual shuttle-bus nutrient that moves calcium out of your arteries and into your bones! But since MK-7 is expensive to produce, most vitamin companies give you the cheaper and inferior MK-4 subtype. Don't settle for this—it won't get the job done for you!You need the bioavailable and highly active long chain MK-7 to constantly help remove calcium from your arteries to keep blood vessels wide open for healthy blood flow and normal blood pressure! MK-7 has been shown in numerous studies to actually extract calcium from the blood and arteries. These are the calcium deposits that can line the walls of your arteries—and make blood flow more difficult.With Life Extension's Super K with Advanced K2, you can help keep your arteries clear of dangerous calcium plaque... promote healthy blood flow, keep your blood pressure healthy and under control, and strengthen your bones to boot! All without any nasty side effects! In fact, Life Extension's Super K formula also provides the full complement of Vitamin K. For people that are on anticoagulant blood therapy, Life Extension Foundation also has a special formula of Vitamin K2 for them as well called Low-Dose Vitamin K2, but if you are taking anti-coagulant or anti-platelet medications, or have a bleeding disorder, consult your healthcare provider before taking this product. I will use no other Vitamin K2 formula except for Life Extension's brand.

I don't normally write more than 2 sentences for my reviews but in this case I felt my review could be helpful for others.My calcium score test was high. I knew I had to make some dietary changes and starting supplementing with Super K which promotes calcium absorption in the bones and out of the arteries.I have mild aortic stenosis and have an annual test measuring any changes and over the last 10 years my "numbers" have remained virtually unchanged. My cardiologist said this is unusual as there is always a worsening of the condition and eventually leading to needing a valve replacement.I can't say if anyone else will have the same results but it's worth a try. You have to think long term.Take vitamin D3 with the K to aid in the absorption of calcium.

At this point, having not opened any of the bottles, the order is just as advertised. I will reevaluate the actual vitamins in the future after I finish my other brand vitamin. This brand was chosen due to its containing the "trans-chemical form" of the vitamin rather than a mixture of "cis/trans-chemical form" of the vitamin.

This looks like a very good product. However if you need to use a blood thinner, I would not use a product with Vitamin K1 in it. If you need just K2, Jarrow Formulas K2 might be a better choice
