You can order at shop.com the Isotonix powder d3 plus K2. Only from Nutrametrix. My daughter who is a nurse practitioner has spoken with the young women who started this brand. The bottle is $33.50. Some are one month, some are two month supply. I currently take their daily essentials and a joint and inflammatory mix. She’s ordered the d3k2 and also a bone health bottle for me. She truly believes in this.

Just a capful of this powder in 2 oz of water once or twice a day preferably on an empty stomach. Each type of powder requires just one or two capfuls . The d3 is 5000units. My daily essentials need an 8 oz glass of water and wait 10 minutes before eating.
I’ll be discontinuing the essentials because, cost wise, 3 bottles will be enough.

There are other liquids or drops online but I would visit a nutrition center or vitamin shop before I buy anything like this online. Do not order anything similar on Amazon.

My daughter does a lot of research. Our whole family and all the grandkids are on something from Nutrametrix. My son in law has no more knee pain. Takes several weeks to feel results. Some of this stuff makes you very regular . We’re feeling a general well being , alertness and sustainable energy.

I’m sure there are very similar and reliable products that are just as effective.
