Life Extension(ライフエクステンション) スーパーK アドバンスK2コンプレックス配合 90錠 ソフトジェル [海外直送品]

This is a fantastic combination of nutrients for skin, bone growth and arterial health in my opinion. I have osteopenia bordering on osteoporosis, awful skin problems from having to use testosterone, heart disease "kills" in my family on both sides, and biopsied precancerous Barrett's disease. Some fairly serious health issues. I have used every prescription bone density prescription available, including prolia injections and 2 years of daily injected forteo with only 7% increase in bone deposit improvement. My cholesterol if left untreated is in the 300 category. I take a powerful acid producing inhibitor due to arthritis medications causing bleeding ulcers. After doing mega reading and research I came accross the benefits of a combination vitamin K. I trust Life extensions products and liked the process used for manufacturing the final product. Life extentions has all the correct multi vitamin k's we need from correct first sources. It is not the by product of some other fist source nutrient or food. That matters to me. A bit pricy but considering the research done by this company for purity and the science that is needed to produce a superior supplement, I think you get what you pay for. Great product you can trust with proven blood test results, which I have every 3 months. Be aware fermented soy is used in this formula, if you are soy allergic or sensitive such as breast cancer talk to your Dr. This supplement has loads of vitamin k activity and you take one easy to swallow soft gel cap daily. Works well for me!

There has been an huge amount of research done in the past decade that reveals the benefits of vitamin D for optimal health. After suffering heart failure 5 years ago, I was shown to be grossly deficient in D3, however, it wasn't until 4 years into my recovery adopting a new dietary lifestyle that I discovered that I needed K2 to work in synergy with D3 for bone strength and my future cardiovascular health. In simple terms, Vitamin D and Vitamin K work together like this....A large portion of arterial plaque is made up of calcium deposits (hardening of the arteries) Vitamin D has undisputed benefits in improving bone development, helping your body absorb calcium and K2 directs calcium to the right places like your skelton and keeps it out of the places that you don't want it, such as your arteries, organs and joint spaces. There is also medical proof that the safety of Vitamin D depends on Vitamin K. Toxicity (which is rare with D3) is actually a result of Vitamin K2 deficiency. Although I did change my diet drastically over a year ago, I was still struggling to get my cholesterol numbers to safe levels. Upon adopting the addition of K2, my numbers changed drastically in a very short time (within 4 months) and continue to improve. This prompted me to educate myself on every supplement I was currently on and other supplements that I added to ensure Heart Health. If I don't understand why I am taking something now, I will not be consistent. And K2 is a must. Life Extention was suggested to me by a health care professional who offers holistic alternatives to standard medication and supplementation.

I even went with their Magnesium supplement after using this. I love the fact you get a 90 day supply on the economical side and the labs testing bottle contents of supplement makers rank LifeExtension as a good brand. I don't seem to get brain fog anymore and stay alert longer, but if you have blood clotting or bleeding disorders talk to your doctor first. They clearly print this on the label and you'd be surprised with how many vitamin suppliers don't do this. You only take one dose a day and it's a small softgel so it's a win all around for me and my needs. When this bottle is up I'll get another. I found this on labdoor.com rated for it's content which surprised me. I'm glad people are doing independent testing now.

I've been using this product for quite awhile and have been pleased with it. But Life Extension, more than just about any other supplement brand, seems to feel compelled to tweak their formulations every year or two. And often this seems to be via increasing the amount of the key ingredients -- even though "more" isn't necessarily better, and sometimes might even be detrimental for a variety of reasons. Well, it looks like they're at it again, this time with Super K. This product already contained a generous dose (100 mcg) of the most important component, Vitamin K2-menaq7. But now it looks like they've doubled it to 200 mcg. Why? Most single-ingredient K2-menaq7 products contain either 45 mcg or 90 mcg, with the latter being a "higher dose." In fact, I don't think I've ever seen another product above 100 mcg. While LEF's change gives me pause I'll keep taking it because it's a good value considering it combines all the key varieties of Vitamin K, and because I only take it every other day (I understand menaq7 has a long half life). And LEF is generally a quality brand. BTW, on a more minor note, I'm sorry to see that they removed medium-chain-triglycerides. Finally, I always wonder why this product doesn't show up in ConsumerLabs' Vitamin K tests. It seems like LEF has been paying CL to be included in most of its tests lately (as denoted by an asterisk when the product is approved -- ie, ConsumerLabs' Voluntary Certifcation Program). When a Voluntary Certification product fails, CL does *not* disclose the failure, i.e. you never even know it was tested. So this makes me wonder if LEF Super K failed the test for some reason. Just conjecture of course, but there *was* an odd situation awhile back where Super K showed up as approved in an older CL Vitamin K test, but then abruptly disappeared from the test results.

I had my vitamin D level checked about a year ago and found it was low at about 20 (30-100 is normal). I started taking D3 supplements,1000 iu, and had my blood rechecked after about 4 months. I was shocked to find the D level had gone down and was now only 17. The doctor just suggested I up my D3 dosage. It didn't make sense that my D would go down after taking the supplement, so I went on line and learned about the need for K2. I started taking 2000 iu of D3 and this K2 and after 3 months my D level has gone up from 17 to 32. I haven't noticed any side effects, but I only take this K2 every other day. By the way, the arthritis pain in my knee and hip joints has completely disappeared. I am very happy with this product!
