Unlike regular joint supplements, you only have to take a single daily dose of Animal Flex. Easy. Potent. Effective. Just take a pack of Animal Flex with any meal during the day and you're set - doesn't matter which meal it is. That's it. As a "core" or foundational supplement, use Animal Flex daily - on both training and non-training days. No need to "cycle" it. If you're smart, don't just use Animal Flex when you have a problem. You can and should use to help prevent problems from arising in the first place. Think of Animal Flex as nutritional "insurance."*

Exercise good judgment and keep this out of reach of children.

Universal Nutrition Animal Flex

Product Highlights

Animal Flex is a joint and ligament formula engineered to help support the health of athletes' joints. Animal Flex has been created specifically for strength athletes such as bodybuilders and powerlifters. Each pack contains several different complexes designed to help support healthy joints, ligaments and tendons. Animal Flex is complete and best of all, only a single dose per day is necessary.*

Animal Flex, like other Animal supplements, is complete and comprehensive. Each pack of Animal Flex consists of several key protective complexes:

  1. A potent joint construction complex to help repair connection tissue*
  2. A lubrication complex to help cushion the joints from lifting*
  3. A support complex to help promote rehabilitation and reduce soreness*
  4. A key vitamin/mineral support blend to help underscore optimal joint health*

Maintaining Structural Integrity

One of the key components to bodybuilding progress is consistency--paying your dues day in and day out in the gym. The cumulative effect of this daily wear and tear over the weeks, months, and years, can be profound. When you're building a house, a big one, you need to make sure the foundation is rock solid because that house puts tremendous pressure on the foundation. Now your body's foundation is your joints, ligaments, tendons, and all the connective tissue--the necessary stuff that supports your muscles, your training. The harder you train, the more massive amounts of weight and the numerous sets and reps performed in a typical workout, the more stress you put on your foundation. This constant pounding can take its toll, weaken it. And when a foundation crumbles, the house comes tumbling down.*

This is where Animal Flex comes into the picture. It works by helping to strengthen joints and ligaments, shielding them from the daily wear and tear brought about by balls to the wall training. The ingredients in Animal Flex can help maintain healthy joint function, elasticity, and flexibility. Many of Animal Flex’s active ingredients provide the basic building blocks that are required to maintain human structural integrity.*

Universal Animal Flex

The Building Blocks of a Solid Foundation

As a joint "constructor", Animal Flex is powered by proven reconstruction nutrients. Animal Flex™ provides the joints with the essential raw materials such as glucosamine (two forms), MSM, and chondroitin… Ingredients designed to naturally protect and restore joint health while strengthening the underlying cartilage and connective tissue. These nutrients, once absorbed, can work quickly and efficiently to aid in the rebuilding of cartilage.*

From a joint lubrication point of view, hyaluronic acid (HA), cetyl myristoleate (CMO), and flax seed oil provide the “lubricant” needed to coat your joints and protect them from the constant grind of training excess and resulting stiffness. These potent joint lubricators naturally restore the oils present in the synovial fluid to make joints work smoothly and painlessly. *

When it comes to joint support, Animal Flex, utilizes potent natural herbal extracts to help address the free radical load--a consequence of inflammation of the joints. Herbs and extracts like turmeric, boswellia and ginger root have been shown to help inhibit pro-inflammatory metabolites, which leads to a strong and prolonged anti-inflammatory effect. A reduction in inflammation is critical for maintaining pain free joints and for protection against degenerative joint issues often related to years of heavy lifting. Unlike pain relievers that only mask the symptoms, the compounds in Animal Flex offers real support and promotes long term joint health.*

Finally, Animal Flex incorporates a specialized vitamin and mineral blend. This blend is added to provide maximum nutritional support. This key vitamin mix provides you with the basic essential micro-nutrients needed for joint health. Nutrients such as Vitamins C, E, zinc, selenium and manganese are needed for to support healthy joints. These nutrients provide the backbone for proper joint health.*

Complete, Comprehensive, Effective

Animal Flex flat out works. Like other Animal supplements, it comes with an ironclad guarantee. We stand behind it 100%. Unlike other joint formulas, you won't need to take Animal Flex 3x a day. Just a single pack a day will do the trick. And unlike other products, Animal Flex was designed specifically for the serious bodybuilder and powerlifter... Not for the casual weekend warrior.*

In short, Animal Flex fortifies the bodybuilder’s structure by supplying the most effective, comprehensive, and potent balance of joint nutrients available. Busting your ass with heavy weights and eating big has consequences. To stay healthy and keep growing you need shelter from the elements. You want to know that your foundation is defended against the constant bombardment of the iron battlefield. It is good to have a dependable ally in this war against the weights. Animal Flex has got your back.*

Animal Flex is your armor against the rigors of iron warfare. It is complete, comprehensive and effective.*

Frequently Asked Questions

Can Animal Flex be stacked with other Animal supplements?

Yup. That's the whole theory behind Animal. It can be stacked with any of the other Animal supplements. For best absorption, leave an hour in between the time you take the Flex and any other Animal supplement.

I only need to take one pack a day?

True. Other than Animal Flex being a joint supplement designed specifically for the serious bodybuilder and powerlifter, what makes Animal Flex unique is that you only have to take it once a day and not three times as with other joint products. Some of the ingredients need to be utilized quicker than others. By incorporating special time-release technologies, those that you need fast are delivered quickly and those that need to be released gradually are time-released.

When should I take the Animal Flex?

Because Flex is for foundational joint support, it is not necessary to take prior to lifting. Animal Flex can be taken either with a meal or on an empty stomach.

I have tremendous joint pain in my shoulder. How quickly can I expect to see results?

Results can differ from individual to individual, but based on our findings from our Alpha Testing program, you may start to feel a difference in a matter of a few weeks. One other thing to note – as with all Animal products, Universal Nutrition offers a 100% money back guarantee on Animal Flex.

Do I need to cycle the Animal Flex?

Nah. You should cycle the Stak 2, M-Stak and Cuts, but Flex should be taken daily to ensure optimal joint health. Flex is one of our "foundational" Animal products--it contains essential, required nutrients that your body needs on a daily basis in order to protect your joints from the overuse and abuse that comes with heavy lifting.

How many pills in Animal Flex?

Five tabs, two caps and one softgel. They're all pretty small too.

How long will Animal Flex last?

44 packs = 44 days.

I took this product for 2 weeks and got extremely sick. I would walke up in the middle of the night with severe stomach pain. I went to see a gastro and he ran some tests including an endoscopy exam (not fun). The gastros synopsis was that the pain was due to animal flex ( way too many pills). I would not recommend animal flex. *

Goal: Build Muscle

I'm in my mid forties and like most of you, fairly active. In addition to lifting weights, I still skateboard - and not very well. As such, I get hurt. A lot.

My biggest issues are lingering pain from a broken wrist and severely sprained ankle. Time really hasn't healed them plus they still get tweaked a bit skating and lifting, so I learned to live with it - till a friend suggested Universal's Animal Flex.

Within a few weeks I was feeling better - less nagging in both trouble spots and even better flexibility (or rather, I was able to stretch fuller / deeper without pain). I was impressed, yet skeptical that Animal Flex was real reason behind it. So, I went to something cheaper. In a couple of weeks, soreness began to rise, so I of course went back to Animal Flex, and soon felt better again.

I still wasn't convinced. I have now "cycled", for lack of a better term, off of Animal Flex four or five times, but never again.

There really is nothing better for joint support, so while it may cost a little more than some joint supplements, it is well worth it. *
