Customers review summary

The Super K supplement appeals to customers for its targeted vitamin K1 and K2 blend that supports bone and cardiovascular health. Its balanced formulation complements vitamin D3, provides multiple K forms, and comes in capsules many find easy to swallow while customers report improved bone density. A few customers note recent formula changes that add maltodextrin and soy and reduce MK7 per capsule, yet many still find Super K effective for bone support.

Delivery issues due to heat!

I love the product however was not too sure upon receiving the product as they were all stuck together from I am assuming from heat during transit. I called regarding this issue and was concerned it may affect the quality of the product. She was very helpful and had suggestions, I was told it does nothing to downgrade the quality of the product.

Adding K2 for better absorbtion of D3 .

Was advised to use K2 with B12 and D3 for better or more correct distrtibution for other vitamins...maybe the next health check reveals any difference than before...meanwhile trusting this brand as it comes highly recommended by a family user who is a long term client of Life Extentions. The service is great, items arrive in a very timely manner.

How does Vitamin K2 help with osteoporosis?

A shopperSep 18, 2014

As best I understand, K2 tells your body where to put the calcium. Without enough K2 in your body, the calcium may go into your arteries instead of your bones, which is not such a good thing! It is important to read the label and be sure you are getting K2 and not just K1. K1 helps with blood clotting and that is not what you are looking for. It is common to be deficient in K2 with our modern diets. Also have your Doctor check your vitamin D level. You may also need a supplement for that.

Susan SSep 18, 2014

Vitamin K2 is just one of the important supplements in helping bone to rebuild itself. Also important is vitamin D3, magnesium, dietary calcium and exercise.

Patricia TSep 18, 2014

From what I have read K2 helps with the assimilation and absorption of Calcium and helps strengthen bones in post menopausal women.

Judith GSep 18, 2014

Super K With Advanced K2 Complex helps your body absorb the calcium. It is very important to take for your bones.

I have no idea. I suggest that you call Life Extension. They are very knowledgable and helpful, and would definitely be able to answer your question. I tried to provide their phone#, but this site doesn't allow phone #s. Goodle Life Extension. Their # will be on the site.If you supplement with calcium....vitamin K2 is a MUST!

My suggestion is go to the source, LifeExtension website and ask your question.

can vitamin k2 be replaced with bayer asperin?

A shopperOct 14, 2016

Best Answer: I take K2, along with D3, so that calcium can be utilized by my bones. Without the addition of those two, supplemented calcium goes to other unwanted places like the artieries. I've only heard of K2 being used in conjunction with calcium, and never as a replacement for aspirin, but I'm not a professional.
