Questions? We've Got Answers!

How is Whey Protein different from Body Protein?

Our Fat Flush Whey Protein is derived from cold-filtered U.S. whey, providing complete animal-based protein rich in immune-supporting compounds and branched-chain amino acids. Our Fat Flush Body Protein is plant-based, using pea and rice protein to deliver a complete amino acid profile suitable for vegan or dairy-free diets.

Is this whey protein powder safe for people who are lactose intolerant?

Fat Flush Whey Protein contains very low levels of lactose—generally well-tolerated by most people with lactose sensitivity. However, individual tolerance can vary, so we recommend starting with a smaller serving to see how your body responds.

How do I use Fat Flush Whey Protein?

Mix one scoop with water or blend up with your favorite smoothie ingredients. Enjoy it as a nutritious breakfast, post-workout shake, or satisfying meal replacement to support energy, recovery, and appetite control.

How do I know this protein powder is safe and high quality?

Every batch of Fat Flush Whey Protein is third-party tested for dangerous levels of heavy metals—including lead, arsenic, cadmium, and mercury—and is free from hormones, pesticides, GMOs, and artificial additives. You can feel confident in a clean, pure, and safe protein powder every time.

Who should take Fat Flush Whey Protein?

This whey protein is ideal for anyone looking to support lean muscle, maintain energy, manage weight, or improve overall protein intake. It’s perfect for smoothies, meal replacements, or post-workout recovery.

Our Customers Say It Best

"I love this protein powder so much! It is delicious and nutritious. It is made with high standards. I also make a smoothie with it for my 85 year old mother and she gets so excited when I give it to her every evening when I come home from work. She is lactose intolerant and able to digest this whey powder with zero digestive issues. She is medically fragile and this powder provides her with the protein she needs. We can't or ever want to use any other powder. So worth the money!"
– Desiree L.

"I have been using this protein for several years. It fuels my body first thing in the morning... the BEST start to a day. Lots of energy and so healthy to keep my body healthy and fighting fat!!"
– Idy H.

"This is the best whey protein I have ever used! It is very digestible and does not bother my stomach like many others have. It has a good amount of protein grams per scoop whereas for same grams some others require 2 scoops of similar size. I use it a few times a week. The taste is pleasant. I put it in a blender shake but I bet it would be good all by itself mixed in water!"
– Christina S.

I LOVE FAT FLUSH WHEY PROTEIN!

Fat Flush Whey Protein is so versatile! I can cook with it! I can make wonderful smoothies with it! I love that it has 21 grams of protein. It is so convenient. I can make a nutritional smoothie in just a few minutes! A container of Fat Flush Whey Protein lasts a long time. I love it.

A Great whey protein

It tastes good and good enough to be used on its own but I prefer it in a shake. It’s good mixed with the other plant protein which will yield a thicker shake. They whey alone seems to make it thinner.
