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.

Acquired taste
Size: 16 Ounce (Pack of 1)
Tastes worse than Chlorella. I don't feel any tangible benefits from taking it but also didn't notice anything from Chlorella either. This has a more algae pond water type taste than Chlorella which has a slight umami flavor that I find more tolerable. I like mixing it into a Green Giant drink but it's really just Cocoa, Spirulina or Chlorella, and whey or plant protein. I like the green notes that counterbalance the sweetness. But I prefer Chlorella's taste to this.

High Quality Spirulina at a Great Value
Size: 16 Ounce (Pack of 1)
I’ve been taking spirulina for a few years now, and Micro Ingredients Organic Spirulina Powder has quickly become one of my favorites. The quality is excellent, rich color, fine texture, and no unpleasant odor, which is a good sign of freshness. I really appreciate that it’s organic, non-GMO, gluten-free, and contains no additives. It mixes well into smoothies and juices, and I love that it’s packed with plant-based protein, chlorophyll, and essential vitamins and minerals. For the price and the purity, this is an amazing value. I’ll definitely keep buying it!
