Claims vs. Reality

KOS claims their organic plant-based protein powder provides complete protein to fuel your day along with helping to support a healthy weight. Although most plant proteins aside from soy are incomplete, meaning they are missing or low in one or more essential amino acids, the combination of legumes, nuts, seeds, and grains, in this protein powder provides adequate amounts of all the essential acids required for a complete protein source. 

Protein is one of the more filling macronutrients. Consuming a high protein diet is associated with a decreased calorie intake and subsequent weight loss which can help to support a healthy weight.

How Does KOS Organic Plant Protein Compare?

When comparing KOS Organic Plant Protein to other similar products, such as Ka’Chava plant-based protein powder and Orgain organic vegan protein powder, KOS is medium-priced. You can purchase KOS protein for $49 for a 28-day supply, Orgain protein for $29.95 for a 20-day supply, and Ka’Chava for a whopping $70 for a 15-day supply. 

All protein powders contain similar amounts of plant-based protein with KOS containing 20 grams, Orgain containing 21 grams, and Ka’Chava containing 25 grams. KOS is lower in calories with 140 calories per serving compared to 150 calories per serving in Orgain and 240 calories in Ka’Chava. 

When taking into consideration that KOS contains enough vitamins and minerals to also be considered a well-rounded multivitamin, it brings it into a new category in and of itself. This is closely related to Ka’Chava which touts enough nutrients to be considered a meal replacement shake and contains a good source of most vitamins and minerals but at a significantly higher price point. Orgain is more of a traditional protein shake, it contains some vitamins and minerals but is not comparable to KOS or Ka’Chava. In the end, KOS beats out Ka’Chava with its moderate price point.

Is KOS Organic Plant Protein Safe?

KOS Organic Plant Protein does not contain any ingredients that are known to cause adverse side effects. The only concern when taking KOS is to consider any potential allergens as this product does contain tree nuts (coconut).
