Great guide

This is one of my go to guides for prescribing medications. A must for NP students

Not what I needed
Format: Paperback
I was looking for a book that could guide me through prescribing medication from the most basic conditions to the more complicated patients. This book didn’t even cover sulfur allergies. I was truly disappointed

Pure Green Vitality
Size: 16 Ounce (Pack of 1)
This Micro Ingredients Spirulina has become a staple in my morning routine for a clean, natural energy boost. I love that it’s 100% organic and filler-free, providing a dense source of vegan protein and vitamins without any gritty texture. It mixes surprisingly well into smoothies, and I’ve noticed a genuine improvement in my overall stamina since I started using it.

So good, and good for you
Size: 16 Ounce (Pack of 1)
I blend mine with 4oz Tart Cherry juice and water. Yes...it smells bad...but it so good, and good for me too! I will be updating to a subscription order.
It being a powerful antioxidant, good for your heart is all it took for me to add this to my routine.
