A big, beautiful, gift of a book!!
Format: Paperback, Format: Paperback
I hadn’t even made it past the intro before I had to email Dana and thank her for this book. THAT is the energy this book contains.
Her heart-centered distillation of LOTS of research and knowledge connects the dots so effortlessly and joyfully.
It seems every time I pick up this book I feel inspired, smarter and connected to it ALL!
This book is a gift!

Book content good but formats for both kindle and hard copy versions are not as expected
Format: Paperback, Format: Paperback
The info in the book is good however I originally purchased the kindle version but the format was difficult to read. It’s not like a regular kindle book. The book was beautiful and the pictures inside were in color.
So I decided to go ahead and order the hard copy even though it was very expensive. I received it today and it’s in all in black and white. No beautiful colored pictures.
For $45 it should be in color like the sample or kindle version. I spent $55 for both versions and neither is what I expected format wise. Just disappointing. It would be 5 stars of these issues were fixed. I attached a page of the kindle vs paperback.

The Best Fluoride-Free Toothpaste I've Tried
Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)
I've been using Davids Hydroxi Fluoride-Free Nano Hydroxyapatite Toothpaste for several weeks, and it has completely exceeded my expectations.
The first thing I noticed was how clean and smooth my teeth felt after brushing. Unlike many natural toothpastes, it leaves a genuinely fresh feeling without being overly harsh. The natural peppermint flavor is refreshing and pleasant without the intense burn that some mint toothpastes have.
What really impressed me is the nano-hydroxyapatite formula, which is designed to support enamel remineralization and reduce sensitivity. My teeth have become noticeably less sensitive to cold drinks, and they feel stronger overall. Nano-hydroxyapatite is gaining attention as a fluoride alternative because it can help replenish minerals in enamel and reduce sensitivity.
I also appreciate that it's:
Fluoride-free
SLS-free
Made in the USA
Vegan
Uses high-quality ingredients
Comes in a recyclable metal tube
The whitening is subtle but effective. My teeth look brighter without any increased sensitivity, and the toothpaste is gentle enough for daily use. The inclusion of xylitol and hydroxyapatite makes it feel like a premium oral care product rather than just another natural toothpaste.
While it's more expensive than conventional toothpaste, the quality and ingredients justify the price. Even dental professionals reviewing hydroxyapatite toothpastes have noted benefits for remineralization, sensitivity relief, and plaque reduction.
Overall: 5/5 stars. If you're looking for a fluoride-free toothpaste that supports enamel health, helps with sensitivity, and leaves your mouth feeling exceptionally clean, Davids Hydroxi is absolutely worth trying. Highly recommended!

Mild mint taste
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I wanted to go fluoride free with my toothpaste so I decided to give this a try. I like that the flavor isn’t overly strong and it hasn’t caused any irritation at all. It doesn’t foam up as bad as my old toothpaste did. It is important to me that it’s all natural and fluoride free. My first check up at the dentist after using it went really well so it cleans your teeth really well. I would recommend it
