a coffee, tea, and alcohol drinker so i've gone thru a few of these. i knew i wouldn't see immediate results so i just tried to consistently brush my teeth with this. i can't say it made my teeth whiter but i think it brightened my teeth and helps to prevent it from staining? i didn't irritate my teeth or gums which is important, it helped my mouth to feel cleaner or was it bc of the flavors in it that makes it feel like that? also this little container is too expensive!

Great Product

Its a good product. It works gradually whitening teeth. I use this powder on top of the Boka Prebiotic toothpaste and I have to say I am pretty impressed how clean my teeth are, the whitening and no sensitivity issues.

Awful packaging

Just got the product so I can’t give opinion on if it works to whiten my teeth but I will say the packaging is awful. The powder gets all over the lip of the container and all over the sink. Hard pass unless you want to clean your sink each time you use it.

all the information you need in one book

Format: Paperback

I recently picked up Astral Projection for Beginners, recommended by a friend, and I wish I had discovered it sooner! Having tried to master astral travel with another book, I struggled to make progress, but Grace’s guide covers everything you need to know to successfully navigate this fascinating practice. The book delves into techniques for transitioning from your physical body to your astral body, addressing the fears that may arise during the process. Grace explains how fear can pull you back into your physical form, providing insights on what to expect when you embark on astral travel. This comprehensive approach makes it an essential read for anyone serious about exploring this realm. One of the standout features of the book is the inclusion of various case studies detailing the experiences of individuals who have successfully astral traveled, along with Grace’s own firsthand accounts. This blend of practical information and personal narratives makes the material relatable and engaging. You learn so much from others’ experiences, and it adds a layer of authenticity to the guidance provided. I had a close call with astral travel just last night while using the rope technique. When I caught sight of my physical body from my astral body, I panicked and was instantly pulled back. Grace addresses this fear in her book, explaining that it’s a common reaction and offering strategies to overcome it. I appreciated her reassurance and guidance, which gave me the confidence to try again tonight. As I was finishing the book on my way to New York, I felt inspired and determined to attempt astral travel again. I highly recommend this book to anyone interested in this practice. It’s a well-rounded resource that includes all the information you need—and then some—to successfully explore the world of astral travel.
