Animal Flex is a supplement designed to help you have better joint health, function, and mobility. It is a turmeric-based supplement meant to reduce joint pain. 

Joint pain is a huge problem in the US. According to the CDC, nearly 15 million Americans suffer from arthritic joint pain, with 1 out of 4 of those individuals describing their joint pain as severe and debilitating. Most cases of arthritic joint pain are due to the mechanical wear of the cartilage and connective tissue in joints.

Given the prevalence of joint pain, a lot of companies have come out with products claiming to reduce and prevent joint pain due to arthritis. Pain is tricky to pinpoint, and many products that claim to help with pain are nothing more than a placebo.

Unfortunately, scientists don’t understand much about how pain conducts in the body or how the brain processes pain and less about how to treat pain. Most pain treatments involve administering anti-inflammatories or drugs that block pain signals in the nervous system. 

In today’s review, we will talk about Animal Flex pills, including its pros, cons, where to buy, ingredients, and whether or not you should try it. Our Animal Flex review can help you know more about this supplement and how you can benefit from using it, so keep reading for more!

About Animal Flex 

Animal Flex is a joint supplement in pill or powder form made by the nutritional supplement company Animal. The primary mechanism of action for Animal Flex is due to turmeric.

Turmeric has many proven benefits and is a popular supplement for managing pain due to its verified anti-inflammatory properties.  All you have to do is take one pack daily in the morning with breakfast, and you should feel pain relief the whole day—no messy powders or liquids to deal with. 

Animal Flex has won several prestigious awards from bodybuilding organizations, and many professional lifters and bodybuilders advocate for its efficacy. Animal Flex protects your connective tissue and stimulates cartilage production to repair damaged joints.

Each packet contains three primary complexes that repair connective tissue, lubricate and cushion joints, support rehabilitation, and reduce soreness and inflammation.

Animal Flex is not just a pain reliever but actively works to prevent future pain.  It also gives you your full daily value of vitamin C, E, zinc, selenium, and manganese.

Ingredients in Animal Flex Pills

The main ingredients in Animal Flex pills are:

  • Turmeric root
  • Glucosamine
  • MSM
  • Chondroitin

We have covered turmeric before on this site with good remarks. Turmeric is one of the few common workout supplement ingredients proven to have certain health benefits. Turmeric is a known anti-inflammatory, so it can reduce the swelling of joint pain. The curcumin in turmeric is believed to interact with cells that produce lymphocytes that cause swelling. 

Glucosamine and MSM are two compounds that are believed to increase the production of cartilage. Most glucosamine is harvested from the shells of shellfish, while MSM is usually produced synthetically in a lab. Chondroitin is a substance similar to glucosamine and is believed to have similar cartilage-regenerating properties.

Out of all the ingredients in Animal Flex, glucosamine has the most clinical evidence backing its efficacy. While many claim turmeric can help with all kinds of problems, the clinical evidence supporting that position is relatively thin. The only downside is that since glucosamine in supplements is usually made from shellfish, people with allergies or vegans can’t eat it. 

How Does Animal Flex Work?


Animal Flex pills are supposed to do two main things; reduce inflammation in the joints and stimulate the production and maintenance of cartilage. Inflammation and lack of cartilage are the two major causes of joint pain post-workout. 

We should specify that Animal Flex only manages pain arising from strictly mechanical joint wear. Joint pain can be caused by a variety of other underlying conditions, such as autoimmune conditions.

Animal Flex pills are not meant to function as a treatment or cure for joint pain; just a way to manage symptoms. 

Animal Flex Side Effects

The ingredients in Animal Flex have all been tested as having a very low toxicity level.

The only ingredient that might cause you some problems is turmeric, which can cause nausea, diarrhea, and upset stomach if you are not used to it. These symptoms should go away after a few days.
