Jacked Factory Flex-XT Overview

What You Need To Know About Jacked Factory Flex-XT

Flex-XT Joint Support is advertised as a sports supplement to help improve joint and cartilage issues, but it seems that many customers are using this as a support to medical conditions such as osteoarthritis and carpal tunnel syndrome. It is important to remember that supplements are not intended to treat medical conditions, so if you have one of these or have sustained a sports injury, you should visit your doctor before self-medicating.

Taking a supplement like this to remove the pain of your workout regime is like putting the horse before the cart. If your workouts are causing you pain, you should change your regime rather than trusting that this supplement to clear up the damage.

What Are The Side Effects Of Jacked Factory Flex-XT?

Customers have not mentioned any side effects which is good. However looking through the ingredients list and there are a couple of risks. Boswellia may cause diarrhoea, nausea, acid reflux, increased menstrual flow, miscarriage, and skin rash.

Turmeric is safe at the quantities per serving here, though can cause a range of side effects including increased heart rate and blood pressure at servings over 1500mg a day. It is possible if you are especially sensitive you may notice these effects.

How Much Does Jacked Factory Flex-XT Cost?

Flex-XT Joint Support is not very expensive. Buy from the Jacked Factory website and it costs $24.99 for a bottle of 30 capsules. If you use only one a day this is the equivalent of one month’s supply. However with the advice to take 2 capsules daily if required, you may find your supply lasts only 2 weeks.

You can also buy Flex-XT Joint Support via Amazon where it is on sale from various sellers for as little as $12.99.

Our Verdict On Jacked Factory Flex-XT

Jack Factory Flex-XT Joint Support seems a little hard to prove. You may find that taking this supplement over a few weeks because you have a temporary sports injury may give you the impression that it works because swelling goes down and pain is eased. However, you may also find that resting and just giving the body time to recover gives the same results.

Some people are using Flex-XT Joint Support as a remedy for real medical conditions. It is important to remember that supplements like this are unproven and not supposed to target real medical conditions. If you think you have a real sports injury, carpal tunnel syndrome, or any other condition, you should take the advice from your doctor. Herbal supplements may ease the pain but in most cases, including arthritis, research has found that prescription medication and gels are more effective. Even if you want to go down the herbal route, getting some advice from a trained professional is better than self-medicating with this particular supplement.

Overall, we do not approve Jacked Factory Flex-XT Joint Support to the Watchdog readers.

Jacked Factory Flex-XT Key Features

Flex-XT Joint Support is a supplement aimed at athletes and bodybuilders looking to improve joint pain derived from overtraining or injury. It is in capsule form rather than a cream or gel, and we do advise caution if you are taking this supplement in order to continue with a strenuous exercise regime.

Herbal supplements like this one are not designed to replace medical advice and could lead to further damage. The best thing to do if you have suffered an injury is to take trained advice and rest, and to wait until you fully recover.

Jacked Factory Flex-XT Facts

  • Each bottle contains 30 capsules
  • Contains a blend of branded ingredients
  • Made in the USA

Flex-XT Joint Support contains five ingredients predominantly derived from herbal sources. The principle of these is turmeric. High in antioxidants, turmeric has been tested as an anti-inflammatory and may be effective at treating joint swelling, pain, and arthritis.

How to Take Jacked Factory Flex-XT

  • Take one (1) capsule on an empty stomach
  • An additional serving of 1 capsule may be added 6-8 hours later
  • If you experience any undesirable effects, stop use immediately and consult with your doctor

Flex-XT Joint Support also contains a herbal extract called Boswellia, which is a trademarked substance from Sabinsa a well-known corporation in the supplements world. Boswellia is an extract from a tree called Boswellia Serrata (Indian Frankincense) and research suggests it improves joint mobility and circulation to joints. A combination of Turmeric (Curcumin) and Boswellia is becoming increasingly popular in supplements aimed at improving arthritis.

In addition, there is a branded supplement called FruiteX B which increases Boron in the body supposedly for fast-acting joint support. There is Hyaluronic acid, a substance present in the human body that protects the joints from damage. It is also present in the eyes.

The final component is Bioperine, a branded black pepper supplement that may enhance bioavailability of the other ingredients. Check out the ingredients list for more information.

Jacked Factory Flex-XT Concerns:

  • May cause side effects and interactions with drugs
  • You should seek medical advice if you have a medical condition or suffer an injury rather than turn to an unproven OTC supplement like this
  • Although it is aimed at athletes, most users are taking this to alleviate arthritis and other real medical conditions. It does not seem to have worked very well

We have covered Jacked Factory supplements in previous reviews including Jacked Factory ALTIUD. We have also reviewed Jacked Factory NitroSurge, and extreme fat burner Jacked Factory Burn XT.

What Does Jacked Factory Flex-XT Claim To Do?

According to the product information, the key features are as follows:

  • Enhances total joint and soft tissue health
  • Helps regulate synovial fluid concentrations in articulations
  • Enhance energy production and vitality
  • Supports cartilage, tendons, and ligaments
  • Reduce pain associated with joint and muscle aches
  • Decreases inflammation in joints
  • Manufactured in the USA in a cGMP certified facility

The advertising describes Flex-XT Joint Support as a “premium-grade joint health supplement featuring research-backed doses of patented ingredients that are proven to strengthen your joints and soft tissues (such as muscle and bone).”

It seems as if you should take this supplement as a preventative rather than a cure,

“Just one dose of Flex-XT per day gives you key ingredients for total joint support, anti-inflammatory benefits, and pain relief.

Let’s face it: You’re not going to be performing optimally when your joints, bones, cartilage, tendons, and other soft tissues are constantly in pain.”

Does Jacked Factory Flex-XT Work?

It might have some effect, but the serving size seems low when compared to the clinical research carried out on the ingredients. However, there is some evidence that the ingredients may help improve knee conditions such as osteoarthritis. Boswellia seems to be effective at reducing all types of inflammation, so sports injuries certainly come into this category too.

Jacked Factory Flex-XT Joint Support may help improve joint health generally, but we would be cautious about using this if you are injured and are looking for a way to train through the pain. Do this and you could make your injury much worse, whereas good old fashioned rest will certainly give better results.

It is important to remember that supplements are not to be used in the place of medical treatment, and this one will cause drug interactions with prescription medication.

What Are The Ingredients of Jacked Factory Flex-XT?

Serving size is equal to one capsule.

  • Turmeric Root Extract (95% Curcuminoids) (400mg): Turmeric contains a yellow chemical called curcumin. There are many potential health benefits to turmeric and some research suggests that it is effective for reducing pain and inflammation for osteoarthritis of the knee, although prescription drug diclofenac seems to work better. We can’t find much in the way as evidence for sports injuries, but the usual serving as an arthritis treatment is between 1200mg and 1800mg per day. Turmeric is often paired with Boswellia and absorption is increased by BioPerine which is present in this supplement. Source
  • FruiteX B (calcium Fructoborate (110mg): Branded supplement from FutureCeuticals, a company that specialises in natural herbal supplements mainly on sale to the trade. Calcium Fructoborate is a compound present naturally in fresh fruit and vegetables and is a source of boron, a vital trace mineral that helps the body handle minerals such as calcium. It has been investigated as a treatment for osteoporosis. FruiteX B caused a slight improvement when tested on people with knee discomfort. Source
  • Boswellin Super (75mg): Branded supplement made by Sabinsa. The active ingredient is a herbal extract called Boswellia or Indian Frankincense. Studies show that it can decrease inflammation by preventing the formation of Leukotrienes in the body. Leukotrienes are molecules that have been identified as causing inflammation. Inflammation is simply anything that is red, hot, painful or swollen, so applies to sports injuries as well as chronic conditions such as osteoarthritis. Source
  • Hyaluronic Acid (50mg): Substance present in the human body (eyes and joints), and used for age-related conditions such as in cataract operations and arthritis. Hyaluronic acid forms a cushion around joints for protection. When this dries out, the joints rub against each other causing the pain of arthritis. In cases of arthritis, Hyaluronic Acid is usually applied by injection. Most uses for Hyaluronic acid rely on topical application, as drops or cream rather than in supplement form.
  • Bioperine (5mg): Another Sabinsa supplement, Bioperine contains a chemical called Piperine present in black pepper which helps increase bioavailability when used with other ingredients. Source

Does Jacked Factory Flex-XT Have Any Side Effects?

Customers have not mentioned any side effects which is good. However, looking through the ingredients list and there are a couple of risks.

Boswellia may cause:

  • Diarrhoea
  • Nausea
  • Acid reflux
  • Increased menstrual flow
  • Miscarriage
  • Skin rash

Turmeric is safe at the quantities per serving here, though can cause a range of side effects including increased heart rate and blood pressure at servings over 1500mg a day. It is possible if you are especially sensitive you may notice these effects.


Not suitable for individuals under 18. Avoid if you are pregnant, breast feeding or trying to conceive. The supplement will interact with prescription medication including blood thinners such as Warfarin as well as ibuprofen, aspirin and non steroidal anti inflammatory drugs. Speak to your doctor before use if you are taken prescription medication or have an underlying health condition. Take medical advice if you have a sports injury or swelling rather than look to OTC supplements.

Are There Any Customer Reviews For Jacked Factory Flex-XT?

There are customer reviews on Amazon but according to our scam software, some of these may not be genuine.

We took a search through the comments and found some genuine looking customer reviews. It is interesting to note that very few of these customers seem to be athletes,

This product contains the supplements I need for reducing inflammation in my body and my joints. It doesn’t upset my stomach. So far it seems good. I look forward to seeing even better results the longer I take it.>

My aunt takes these every day she says they work exactly as expected thank you!

Great customer service, product seems to help alleviate the pain but I am still in the beginning stage so time will tell although at the stage I am at with my pain any help is greatly appreciated.

Not everyone is impressed.

One customer used it to alleviate carpal tunnel syndrome. This medical condition can be easily remedied by a simple operation but perhaps this US-based customer could not afford proper medical care so looked instead to this OTC supplement.

Severe carpal-tunnel is a pain. Just started my second bottle and I’m beginning to feel some improvement. I may also have some increased flexibility, but the jury is still out.

This customer felt it was overpriced and ineffective,

Buyer beware! This product is deceptively labelled. It reads: “Serving Size: 1 Capsule” followed by “Servings per Container: 30.” However, the directions instruct you to take one capsule followed by another capsule eight hours later.

At two capsules a day instead of one, you’ll blow through a bottle in 15 days, not 30. For the price, this isn’t worth a mere two-week supply.  Perhaps if it worked better, but I barely noticed any results. Very overpriced and ineffective for 15 day’s worth of product.

Does Jacked Factory Flex-XT Offer a Money-Back Guarantee?

According to the advertising, there is a 100% money-back guarantee. The company states that if for any reason at all you aren’t satisfied, simply send it back within 30 days for a full refund.

However, there are no further details and the guarantee policy is not mentioned in the terms and conditions. With only Facebook messenger or email as a way to contact the company, you will have to trust that they will get back to you in time to return the product within the 30 days deadline
