As a certified personal trainer, I’ve been a longtime follower of Dr. Jim Stoppani, and I have used quite a few of the products created by his company JYM supplement science.

One such product is Shred by JYM -- part of their weight loss product range.

However, when I was asked by a client whether I had some experiences to share from other clients, I didn’t have any data and research to show.

Just like our team has done on over 50 other fat burning supplements, we went through an extensive research and test phase on Shred JYM.

So, let’s get right into the Shred JYM review.

What is Shred JYM?

JYM Shred

Shred JYM is a fat burner supplement designed by fitness and bodybuilding guru Dr. Jim Stoppani. Its main goal is to increase your metabolic rate for more effective fat loss.

Our tests suggest that this product could potentially help with a general weight loss program or a cutting phase for bodybuilders.

Our initial thoughts on this JYM Shred fat burner were positive because of the company behind it.

JYM Supplement Science, in general, is a popular brand in the fitness industry mainly because its products are heavily based on scientifically proven ingredients with a general lack of fillers and additives.

According to the makers, the product has been designed to complement a strict diet and training routine.

And that’s important.

You should not expect it to work miracles by binge-watching Netflix while stuffing your face with junk food.

There are also product claims about limited side effects, and we’ll get to those below.

Shred JYM Benefits

With only six synergistic ingredients as you’ll see below, Shred JYM is designed to help facilitate fat loss within the body through three stages: releasing of fat from fat cells, transport that released fat into the mitochondria for energy use, and increasing metabolic rate.

This three-stage process aims to:

  • Increase calorie burning
  • Enhance metabolism
  • Boost energy levels
  • Accelerate fat loss

Shred JYM Ingredients

Supplement Facts of Shred JYM

Most JYM products have in common that they don’t go overboard with huge lists of obscure ingredients. With Shred, they have kept it to the following six.

1 - Acetyl-L-Carnitine (1,500mg)

Numerous studies have been conducted, and while some initial research results were a bit mixed, there is one study I found on the National Center for Biotechnology Information website that suggests a link between this ingredient and weight loss as well as training performance [1].

Based on feedback from my dietitian, there are also limited negative effects associated, and she reported that it might be helpful for increased workout energy.

Many users say that Shred JYM is not only effective in losing weight but also in giving them the boost they need for intense workouts.

2 - L-Tyrosine (500mg)

This isn’t an ingredient that provides specific fat-burning capabilities. Instead, one of the studies found on the National Center for Biotechnology Information website suggests that it supports and improves brain function and overall mood [2].

The benefit this could provide is for some additional motivation to stick with your diet and exercise routine. If you’re doing extended fasting periods, it may also help you fight those urges to reach for snacks.

What I would point out, though, is that the JYM Shred serving size of this ingredient isn’t as high as has been scientifically tested. So this may not be strong enough.

3 - Green Tea Leaf Extract (500mg)

Green tea leaf extract is mainly used in the health and diet industry for its antioxidant properties. Having a few cups of this tea every day has been shown to help with detox.

But one extensive study has also shown that green tea extract may be directly linked to fat oxidation [3].

The good news here is that Shred JYM seems to contain a large enough dose that matches what several studies used to confirm the metabolism impact.

Combined with a proper nutrition and exercise program, our clients have seen a little bit of fat loss after 2 months of consistent use.

4 - Caffeine Anhydrous (200mg)

Caffeine Anhydrous in a small cup

Caffeine has long been known to improve your mental focus and metabolic rate by triggering thermogenesis. It’s a natural fat burner that most weight loss products rely on.

It works by slightly increasing your core body temperature to burn extra calories from stored body fat.

Based on online reviews, many users say they feel energized a few minutes after taking the product, which may be caffeine revving up their metabolism.

However, the side effects could be feeling jittery, especially if you tend to drink coffee during the day.

5 - Capsimax Cayenne Pepper Fruit Extract (50mg)

Cayenne pepper extract is another fat burner that belongs in the thermogenic category. Along with caffeine, it’s possibly one of the ingredients with the largest amounts of research and review done.

One study, in particular, was able to link it to a significant effect on fat to make it a potential treatment for obesity [4].

“Although the burning sensation of cayenne pepper can be a bit too much for some, taking cayenne pepper extract can provide the same health effects without the fiery heat.”

-William Gamonski, Nutrition Writer

6 - Synephrine (20mg)

Synephrine is a pretty new ingredient in diet supplements, and there are some possible links to appetite suppression.

But the more interesting study we could find tied synephrine to the release of fat from fat cells [5]. This was specifically measured during and after exercise, so it’s not a get slim on the couch type of ingredient.

The one thing to mention is that the Shred JYM dose of synephrine is considerably lower than the amounts used in most studies.

But many users reported that it helped them control their appetite and reduce their cravings, which may have contributed to their weight loss.

Shred JYM Capsules For Convenience

Taking a JYM capsule

Most of the popular supplements used in the fitness industry come in powder form. These are your typical pre and post-workout shakes. Over the years, the taste and texture have improved a lot.

However, we have yet to find a fat-burning supplement in powder form that tastes good.

Maybe it’s the ingredients.

Either way, we think that JYM Supplement Science made a good decision to provide Shred in the form of capsules.

Based on our tests, they are much easier to take, and you could even bring them with you if you plan to take them later in the day when you’re not at home.

Shred JYM Pros and Cons

Let’s start with the most important part. Based on the green tea extract, cayenne pepper, and caffeine, there is good support that it should help with fat loss. We saw reviews from people in a weight loss program and bodybuilders in the cutting phase, reporting good results.

However, like what our dietician pointed out, some of the ingredients may not be in sufficient amounts per serving to notice major changes in your body.

We also noted that there are some reports of it causing some upset stomach when taking the supplement without food.

And having to swallow six pills at one time doesn’t seem ideal either.

Pros
  • Created by one of the leading brands in the fitness industry
  • Positive review comments that it may increase your metabolism
  • It contains no artificial or filler ingredients
Cons
  • Some reports of upset stomach and bloating
  • The caffeine dose could make you jittery
  • The recommended dose of 6 capsules needs to be taken in one go

JYM Shred Side Effects

Having an upset stomach from a supplement side effect

We already hinted at the fact that some of our testers mentioned that an upset stomach is quite common. That may be down to the high dose of green tea that you would take in one go.

However, there are other side effects we noted, as well.

First off, there’s quite a lot of caffeine in this supplement. For some people, that could lead to jitters and trouble sleeping.

It’s better to avoid it later in the day or if you have some blood pressure issues. The manufacturers recommended taking it at least 6 hours before bedtime.

Caffeine could also cause headaches for some people, so if that’s something you tend to experience with coffee, then it’s better to find a different supplement.

If you’re not a fan of caffeine, check out our list of caffeine-free fat burners.

When I tried out Shred JYM, I took 6 capsules (which is honestly inconvenient) during lunch to avoid any stomach issues. But there are still days when it would cause me to feel bloated for several hours.

Some of our clients also had a similar experience, whether they take the supplement with or without food.

Where Can You Buy It?

JYM Shred

You can buy Shred JYM from the product's official website, GNC.com, or bodybuilding com.

We have seen it offered on eBay and other online marketplaces. But we strongly suggest you avoid that kind of risk.

There have been increasing reports of counterfeit products being sold. In the best case, they'll do pretty much nothing. But in the worst-case scenario, they could impact your health.

Always stick with trusted retailers.

A bottle of 240 capsules costs around $30, which is a pretty good price for a 40-day supply. It's cheaper than most fat burners in the market.

They also offer free shipping for orders above $69.99.

But if you're not fully satisfied with the product, you can have it returned within 30 days from purchase to get your money back.

User Reviews

To not make this come across as just our opinion, we wanted to highlight a few JYM shred reviews that seem to show the same results we had.

She was on a strict diet and fat loss program to manage her diabetes better, and there seemed to be positive results on how well it worked to burn some extra energy.

- Cheryl from Topeka

He was in a cutting phase and was trying to extend some fasting periods in the morning. However, he didn’t find it impacted his appetite enough.

- Mark from El Paso

She noted an increase in energy during her exercise routine, and with an unchanged diet and calorie intake, she did note some more fat burning taking place.

- Sonja from DC

After adjusting the dose and taking it with food, he still reported that some of the ingredients seemed to not agree with his body. From bloating and cramps, it just wasn’t the best experience.

-John from Orlando

Fat Burner Alternatives

PhenQ

We discovered that PhenQ is one of the most powerful fat burners that quickly helps both men and women lose excess fat. It contains six unique ingredients and a weight loss formula called α-Lacys Reset® to promote weight loss in five ways effectively.

Like Shred JYM, it has thermogenic ingredients like caffeine, L-carnitine, and capsimax to attack your weight. But it also has added nopal and minerals for better appetite control and stronger immunity.

But compared to Shred JYM, it has lower ingredient doses, making it more suitable for regular people who want to lose weight, curb cravings, and improve energy levels.

LeanBean

Based on our expert review, LeanBean is considered the best natural fat burner for women that targets stubborn fat through ingredients like green coffee bean extract and glucomannan.

Unlike Shred JYM, which contains caffeine, it doesn’t heavily depend on stimulants like caffeine to boost metabolism. Instead, it uses natural thermogenics and added vitamins and minerals for a more sustainable weight loss without the side effects.

It’s slightly pricier than Shred JYM because it’s 100% vegan-friendly, making it an ideal fat burner and appetite suppressant for women looking to burn fat more efficiently.

Instant Knockout

Instant Knockout is a 100% vegan-friendly fat burner that speeds up fat burning through a combination of common thermogenic ingredients like caffeine, green tea extract, and L-theanine.

Unlike Shred JYM, which uses synephrine and cayenne pepper extract, it contains glucomannan, chromium, and other minerals to keep appetite under control.

Also, it is created with bodybuilders and performance athletes in mind, which can explain the higher doses of its ingredients compared to Shred JYM. Yet, our tests indicate that it still works well with active people who want to lose excess fat and achieve visibly toned muscles simultaneously.

FAQ

How Do You Take Shred JYM?

You take Shred JYM once daily by swallowing six capsules containing the active ingredients. You should plan your intake close to meals, especially when you’re first starting to ensure you don’t have any adverse reactions.

What Is the Recommended Shred JYM Dose?

The recommended Shred JYM dose is six capsules per day, all taken in one go. You could spread them out a bit from morning to early afternoon. But due to the caffeine content, you may want to avoid taking it later in the day.

Can You Take Shred JYM and Pre JYM Together?

No, you cannot take Shred JYM and Pre JYM together. Both of these supplements combined contain 500mg of caffeine. That’s the same as 5 cups of coffee, and your body may not react too well to that stimulation level.

Is Shred JYM Safe?

Yes, Shred JYM is safe, as all the ingredients in the product are generally classified as safe to use. However, if you have specific allergies or a sensitive stomach, you might negatively react to it.

Is JYM Shred Effective for Long-Term Weight Loss?

JYM Shred is designed for short to medium-term use to kickstart or enhance a weight loss journey. For long-term sustainability, it should be combined with a balanced diet and regular exercise, as reliance solely on supplements is not a viable long-term weight loss strategy.

How Does JYM Shred Affect Workout Performance and Recovery?

JYM Shred can boost workout performance by increasing energy levels and focus, thanks to stimulants like caffeine. However, users should be aware of their caffeine tolerance, as high doses can potentially lead to increased heart rate and affect recovery times.

What Are the Differences Between JYM Shred and Non-Stimulant Fat Burners?

Unlike non-stimulant fat burners, JYM Shred contains stimulants like caffeine, which can provide an immediate boost in energy and metabolism. Non-stimulant fat burners, on the other hand, often focus on appetite suppression and fat oxidation without the risk of stimulant-related side effects.

Our Verdict on JYM Shred

Overall, we did find that this fat loss product seems to work for what it advertises. Our clients were able to lose some additional body weight, and online reviews are supportive of this.

However, we also noted quite a bit of feedback and reviews that there are common side effects like stomach cramps.

The best results we have seen are from PhenQ. Not only does it seem to help burn away stored body fat, but many of our clients like the extra energy it provides.

And the best part is that the ingredients are 100% safe, with scientific backing. That means no side effects, just effective fat-burning all the way.

Other users have also found it effective for fat loss. The images here speak for themselves:
