Horchata Vibes

LOVE it!!! Not too sweet, and more protein than other brands. The flavor says Cinnamon French Toast, but I get more Horchata vibes. Delivery was quick, mixes very well - no clumps. A protein I can feel good about, look at those ingredients! My absolute favorite, will definitely be subscribing!

I ordered the French vanilla and could not drink. Really disliked the flavor but was excited to try given quality ingredients.

Clean and tasty

Love that it is so clean, free of sucralose, fillers, heavy metals and other nasties. Currently using it to bake into a pre-workout bar.

A.
Whey Protein Isolate undergoes additional processing to remove most of the lactose and fat content, leaving >90% protein. Whey protein isolate is often preferred over whey protein concentrate due to its higher protein purity and reduced allergen content.
A.
Protein is known for its satiating and thermodynamic effects, which can help reduce hunger and increase calorie expenditure. Incorporating whey protein isolate into your diet can assist in weight management by promoting fullness and an energy deficit.
A.

The natural flavors used in our products are derived from natural sources such as plants, fruits, or spices to enhance the taste of our products. For example, the organic compound isobutyl acetate is found in raspberries, pears, and pineapples and is used commercially to impart natural fruity flavors.
 

Food labeling practices require the term "natural flavor" to be used instead of the specific constituents that comprise the flavoring. We prioritize using natural flavors to provide a clean and enjoyable taste experience for our customers. If you're looking for a whey protein isolate with no natural flavors, try our Unflavored option!

A.

Some flavors do contain nuts (please refer to the label for allergen warnings). We test for gluten and the main 8 FALCPA allergens in all of our products. We have an allergen segregation program and sanitize our lines after each allergen-containing production run.
 

We are also NSF-certified on the facility level - this means that our allergen control and segregation program is approved at the highest standard possible. Note that our peanut-based flavors contain actual peanuts, so those with peanut allergies should strictly avoid these flavors.
 

Whey isolate undergoes further processing to remove most of the lactose, making it a suitable option for those who have difficulty digesting lactose.

A.
Individuals with a milk allergy or severe lactose intolerance should not consume whey protein powders.
A.
Yes, consuming whey protein powder daily is safe for most individuals. However, it's important not to rely on it as your sole source of protein.
A.
Transparent Labs Protein is certified by Informed Choice and Informed Protein for quality assurance, composition, and banned substances. We also test all of our protein with 3rd-party labs for contaminants and ingredient composition. You can find all of our latest 3rd party testing data on this page.
A.
Transparent Labs offers worldwide shipping, with a few exceptions due to import restrictions in the EU and high fraudulent activity in specific countries. Please check our shipping policy for more details.
