About the business
Cantein is an organic hemp protein powder brand based in Monterey, California. The company sells 700g bags with 20 servings of USDA Certified Organic, cold-pressed hemp protein available in three varieties: vanilla (22g protein per 35g scoop), chocolate (22g protein per 35g scoop), and unflavored (28g protein per 35g scoop).
The hemp is mechanically pressed at low temperature without hexane or chemical solvents, and has been tested by Eurofins for heavy metals and cannabinoids. Flavored varieties contain six organic ingredients (hemp protein, MCT from coconut, organic flavor, monk fruit, and salt), while unflavored contains only organic hemp protein. All products are sweetened with monk fruit rather than stevia and contain 0g added sugar.
Cantein positions itself as a complete protein from a single plant source, contrasting with pea-and-rice blends. The company sells directly to consumers through its website and Amazon, with a Subscribe & Save option offering 10% off at $44.99 every 4 weeks compared to $49.99 for one-time purchases. First orders include a 30-day money-back guarantee.

Neighbours ask
How much protein do I need per day?
The RDA of 0.8 g per kg of body weight is a minimum to prevent deficiency, not an optimal intake. Research supports about 1.2–1.6 g/kg for general health, 1.6–2.2 g/kg if you strength train, and at least 1.2 g/kg for adults 65 and older.
What are the 9 essential amino acids?
Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Your body cannot make them, so they have to come from food.
Can you get all essential amino acids on a vegan diet?
Yes. Most plant foods contain all nine essential amino acids, just in different proportions. Mixing plant proteins, leaning on soy, lentils, and seeds, and eating a little more total protein closes most gaps.
Is Cantein tested for heavy metals and THC?
Yes. In September 2025, Eurofins tested a sample of the hemp protein for 4 heavy metals and 16 cannabinoids. A 35g scoop of unflavored had 0.22µg of lead and 0.49µg of cadmium, with no THC or CBD detected.
Can I subscribe and cancel anytime?
Yes. Subscribe & Save is 10% off a 700g bag every 4 weeks. It is month-to-month with no 12-month lock-in. First orders have a 30-day money-back guarantee.
