Why It Stands Out

A balanced plant blend with creamy texture, organic certification, and a mild vanilla taste that disappears nicely into smoothies. The inclusion of a digestive enzyme blend can improve comfort for some users, and the stevia/monk fruit combo keeps sugars low without erythritol.

Creamy & Mixes Well

Coconut milk powder adds body; blends in water or milk alternatives.

Organic & Vegan

USDA Organic, Non-GMO, free from gluten, dairy, and soy.

Gentle Sweetness

Sweetened with stevia & monk fruit; no erythritol.

Enzyme Support

Multi-enzyme blend may reduce heaviness after shakes.

What People Say

“Vanilla is super versatile—blends smoothly with banana + oat milk and doesn’t taste ‘pea-y’.” Reddit user
“If you’re sensitive to sweetness, start with 1 scoop. Flavor’s great but sweeteners are noticeable.” Reddit user

Is This Right For You?

  • You want an organic, vegan protein with a creamy texture
  • You prefer stevia/monk fruit over artificial sweeteners
  • You’re OK with ~150 calories per serving for a shake/snack
  • You value enzyme support for easier digestion

Pros

  • USDA Organic (CCOF) & Non-GMO
  • Creamy vanilla; blends easily
  • 20 g protein with 5-protein blend
  • No gluten, dairy, or soy
  • Includes digestive enzymes

Cons

  • Includes stevia/monk fruit (taste preference varies)
  • Contains inulin (high-FODMAP; may bloat some people)
  • Not the highest protein/serving compared to isolates
  • Vanilla is sweet—some may prefer unflavored

How to Use

Mix 2 scoops with 10–12 oz cold water or your favorite milk alternative. For a thicker shake, add ice and blend for 20–30 seconds. Smoothie idea: 1 banana, 1 cup oat milk, 2 scoops KOS Vanilla, a pinch of cinnamon, and ice. Works well in overnight oats and protein pancakes, too.

Cautions & Considerations

Allergies & Sensitivities

Contains coconut. Formulated without gluten, dairy, and soy. Always review the current label in case of changes.

Sweetness Level

Sweetened with stevia and monk fruit. If you’re sweetener-sensitive, start with 1 scoop and adjust.

Digestive Notes

Inulin (prebiotic fiber) and enzyme blends are helpful for many, but may cause bloating for some. Introduce gradually.

Quality & Testing

KOS states batches are screened for contaminants and heavy metals in line with USDA Organic/CCOF compliance. Look for the latest COAs if available.

FAQs

Is it a complete protein?

When blended (pea + seeds/grains), the amino profile is complementary for everyday use. For precise amino targets (e.g., athletes), view the full amino panel on the label.

Does it contain erythritol or artificial sweeteners?

No erythritol or artificial sweeteners; it uses stevia and monk fruit.

What certifications does it have?

USDA Organic (CCOF certified), Non-GMO, and made in a GMP/NSF facility. It’s formulated without gluten, dairy, or soy.

How sweet is the vanilla?

Moderately sweet. If you prefer less sweetness, halve the serving or add more liquid, cinnamon, or a pinch of salt.
