Hello, thank you for your question. ProMix is 100% grass-fed and finished. ProMix mixes more easily because we add .75% Non-GMO sunflower lecithin. This makes ProMix a good choice if you are using a spoon or shaker bottle to mix, in addition to using in smoothies. We are able to keep our product costs down and still offer the best product possible because we depend on word of mouth rather than ad spending. Thank you.
