Frequently Asked Questions

We love a classic peanut butter banana smoothie (milk, banana, Peanut Butter Organic Protein, and maybe even a scoop of our Focus Organic Mushroom Blend).
Absolutely. We love adding it to peanut butter cookies or even to brownies or a peanut butter, chocolate combo!
No whey! Just our organic protein blend.
While we cannot be certain about everything someone might be tested for, our products are 100% legal. None of our products are on the World Anti-Doping Agency’s (WADA’s) prohibited list, and they are legal all around the world. Most functional mushrooms and adaptogenic herbs have been used for over 5,000 years, so it is very unlikely that they will ever make the list or become illegal. Please be aware that our Organic Proteins do contain hemp protein but each batch is tested for THC and levels are no more than 5 ppm.
Unfortunately, we cannot currently share the amino acid profile of our protein powder. The reasons for this are because we’re not making claims for specific amino acids and the breakdown is currently proprietary to preserve our competitive stance with the product. We can assure you that our protein formulations take into consideration the Protein Digestibility Corrected Amino Acid Score or PDCAAS as it is known in the industry. Our protein is very high quality and the PDCAAS value is 0.83. PDCAAS is evaluated on a 0 to 1 scale, meaning the closer the value to 1, the higher the ability to digest the essential amino acids and greater ability to lose less of the protein quality to waste.
Our organic proteins, depending on flavor, are sweetened with either monk fruit, lucuma, coconut palm sugar, yacon juice powder, or maple syrup powder.
No - but for a reason! We fill all of our products by weight not volume, so your canisters will not be filled to the top with powder. Because these products contain a powder, it may appear less to the eye because of the potential for the powder to condense during transit but rest assured that the package does include the actual number of servings! To help ensure that you receive each of those precious servings, we've included a scoop in each canister for measuring. If you don't see this scoop at the top of the canister, just shake down the contents a bit in case it's settled into your product during transit :)
We do use hemp in our protein blend. If that is allowed for your sport, you are good!
You absolutely can - we love product stacking to get those extra mushrooms and adaptogens in! Our new favorite way is to add a scoop of our organic protein to our Think Organic Coffee for a high protein coffee to start the day!
A dry and cool space.
From what our reviews say, pretty great! Just shake with ice in a shaker for a smooth texture and delicious flavor.
Technically no based on having less calories than what is regulated as a meal. We recommend adding in fruit and dairy for a more full smoothie if you are looking to replace a meal.
