Shredz Fat Burner for Women Review 2019 – What Science Says About Shredz

  •  
  •  

 

Shredz is a US-based supplement company that sells a variety of different products both nationally and internationally. Where the company is based is difficult to ascertain but it is either California or New Jersey. There is also no information about who started the company, when they started, or even why. This lack of information is not uncommon in the supplement industry, but it is always a bit of a red flag.
  Shredz markets separately for men and women, selling products like “Test Max” and “Core Rebuild” to men while selling products called “Detox” and “Toner” to women. The packaging is very well designed for both men and women and the use of testimonial pics is a great touch (though testimonial pics for a supplement are almost impossible to judge – maybe the person got amazing results from diet and exercise rather than the product?).

Maybe you disagree with this statement, but shouldn’t a supplement testimonial involve the person who got results explaining how they think that the product helped them? Because in reality the people giving these testimonials have no idea what the supplements do, or how they work.

But let’s get back on topic here, the product we will be looking at today is the Shredz Fat Burner for Women. This is a supplement that claims to boost metabolism, increase energy, help you reach your fitness goals, and optimize your health.

What is the Shredz Fat Burner for Women?

The main ingredients of the fat burner are split into four different groups. There is Biotin, Pantothenic Acid, SHREDZ Proprietary Blend (which contains the majority of the active ingredients), and Choline Bitartrate.

Annoyingly the Proprietary blend doesn’t give the individual measurements of each ingredient. So when we see that it contains Caffeine, we don’t know how much there is. This is another common yet incredibly frustrating thing that supplement companies do. For this review we will evaluate each ingredient and give you an idea of what it is supposed to do and whether it is scientifically proven to work.

Biotin

Biotin is an essential vitamin found naturally in foods such as eggs, meat, dairy, and nuts. It is believed by many to help strengthen nails and prevent hair loss, but there really isn’t any evidence for this. One study found that Biotin may lower triglyceride levels, but found that it had no other significant effects [1]. There doesn’t seem to be any reason why Biotin is contained in this supplement.

Pantothenic Acid

Pantothenic Acid (Vitamin B-5) is a B-Vitamin (as is Biotin), it is essential for your body but is so common in the diet that it would be almost impossible to be deficient. If you eat meat, vegetables, grains, dairy, or fish then you will be getting enough Vitamin B-5. As with Biotin, there doesn’t seem to be any need for Pantothenic Acid’s inclusion in this product.

Cacao Seed

Also known as cocoa extract, there are quite a few benefits to this ingredient [2]. It appears to improve blood flow, and works as an antioxidant [3]. Of course you could get the same benefits from eating a small amount of dark chocolate each day instead!

Caffeine

When it comes to fat burning supplements, almost every single one contains caffeine as it is one of the best fat-burning supplements around. It has been shown to increase metabolism [4], increases fat oxidation [5], and can also help improve your performance in the gym or within your chosen sport [6].

All in all caffeine is a fantastic ingredient for a fat burning supplement, but due to the high levels of caffeine already found in most people’s diets the effects may be lessened due to the building up of a tolerance.

Green Tea Extract

Also known as green tea catechins, GTE consists of 4 molecules found in green tea. GTE has been shown to have an effect on fat oxidation and metabolism [7] but this is only seen in people who don’t habitually consume caffeine.

There are many other possible benefits, particularly blood flow but again, this is found in people who don’t usually take caffeine.

Cayenne Pepper Powder

Used in supplements as a source of capsaicin, cayenne pepper powder may help fight obesity as it increases lipolysis (fat burning) [8].

Acetyl-L-Carnitine

ALC is an amino acid that helps the body produce energy and may help burn fat, but only if the person taking it is deficient. There definitely seems to be a fat burning effect amongst the elderly [9] but there is insufficient evidence that ALC can burn fat in young people. The increased energy for those that are deficient would be very useful though.

Alpha-Lipoic Acid

This is a fatty acid that is usually taken alongside Acetyl-L-Carnitine, it also helps increase energy and appears to be an effective antioxidant.

Yohimbe Bark Extract

An excellent fat-burning supplement that increases adrenaline in the same way that caffeine does, this leads to increased fat oxidation and a raised metabolism. It is effective at burning fat in obese and in lean people [10] but as with caffeine you can quickly build up a tolerance to it.

One thing that should be mentioned is that a lot of supplement companies don’t put anywhere near as much Yohimbe in their product as is needed to get results. As Shredz haven’t mentioned how much is in their product, it is impossible to say whether the Yohimbe that is in it is enough.

Guggul Extract

This is a pretty poor fat-burner, with little to no evidence that it has any effect. However it does seem to have the ability to lower cholesterol levels and as an antioxidant [11].

Choline

A molecule found in eggs that has the ability to help improve liver health

So does Shredz Fat Burner work?

Without knowing the correct dosages of Caffeine and Yohimbe it is impossible to say for certain, there are certainly a lot of good-in-theory ingredients. As something that will increase energy and improve health this is a good product (though you would have to have a pretty nutritionally poor diet for most of the positive effects to be needed).

As a fat burner it certainly has the correct ingredients to be effective, we just need to know how much of these ingredients there are.

The price of these fat burning pills is between $45 and $60 for a pack, and each pack contains 60 capsules. You can take anywhere from 1 to 3 per day so obviously the value for money will be different depending on how much you take.

The supplement comes with a free eBook that lays out a training program to go alongside. This is a really nice touch and helps to establish the importance of following a calorie-controlled diet and exercising whilst taking the supplement.

The Bottom Line

It is likely that the Shredz Fat Burner for women will help aid fat loss, but that the difference will be minimal. Most of the ingredients could easily be added into your diet, and the ones that can’t are hardly irreplaceable.

If you are planning on embarking on a new exercise and diet regime and you want that extra 2-5% help then Shredz Fat Burner for women will work fine. Incidentally there is nothing within this product that would stop men from getting the same benefits!

Price-wise this fat burner is fairly inexpensive compared to a lot of other companies, and the added eBook also helps make this a decent bang for your buck. The testimonials of past clients are very impressive, but the truth is that they would have got very similar results if they had exercised and dieted without the supplement. So if you aren’t planning on working hard then save your money.

The returns policy seems fair, you need to request a refund within 2 weeks of purchase and you cannot have opened the supplement. This is pretty standard within the industry, at no point do they guarantee results so if you take it for 4 weeks and don’t lose weight don’t expect your money back!
