Product description

An avalanche of favorable studies has resulted in record numbers of Americans supplementing with vitamin D. Since it is virtually impossible to obtain adequate vitamin D from food sources, supplementation with 5,000-8,000 IU daily is required by many aging individuals. Overlooked by almost everyone (except Life Extension members) is the critical importance of vitamin K. If one is concerned enough about their health to take higher dose vitamin D, it seems absurd to miss out on the benefits of vitamin K. For instance, vitamin D facilitates calcium absorption into the bloodstream and thus plays an important role in maintaining bone density. Less recognized is the need for vitamin K to transport calcium from the bloodstream into the bone. Vitamin K is also required by calcium-regulating proteins in the arteries. Together these two vitamins help maintain youthful calcium skeletal distribution while promoting vascular health.

2.0 out of 5 stars ⚠️ TAKE EXTREME CAUTION ⚠️
Reviewed in the United States on 20 December 2021
Anyone who is considering to use this product needs to take extreme caution and make sure that your body can handle the amount of iodine they pile into this. There is a massive excess of too much iodine per serving and it can be extremely damaging to your health. Hyperthyroidism is very likely if you take this every day, which will lead to a whole host of issues to your body and mind.

This review is not meant to scare people off but rather warn you so you don’t have to experience what I did. I never had a single thyroid issue until I started taking this product. I now have developed full blown goiter. Nearly 700% of your daily value of iodine will cause this. Doctors told me to stop taking this immediately. I have since stopped and things have very slowly started to get better.

Life Extension makes great products but I am very disappointed in them for making a formulation like this. PLEASE REFORMULATE THIS L.E. AND PREVENT OTHERS FROM HARM!

Please, PLEASE, be careful! Take caution. I hope this review finds everyone and you strongly consider your options.

P.S. : About 40% of the bottle had capsules that were either half empty or completely empty.
