Ingredients of B4 Fat Burner

Below are the key ingredients of B4 Fat Burner. You may notice that most of these ingredients can also be found in most sport nutrition supplements.


Do you lack in vitamin B3? Well, B4 Fat Burner can support your B3 deficiency as it contains enough amounts of water soluble nutrient niacin. Niacin is known for its function as hormone regulator, DNA repair and regulation of blood flow. Water intake is necessary if you are taking vitamin B3.


Caffeine is a natural stimulant that is mostly found in diet pills, coffee and beverages. B4 Fat Burner contains caffeine in anhydrous form which is instantly absorbed by the body compared to just drinking coffee or tea. Too much caffeine though can produce side effects.

Dendrobium Nobile

BPI Sports call this ingredient as Dendromax, which is used by most of its product lines including B4 Fat Burner. Dendrobium hit the market in 2012 and became an instant ingredient celebrity. What does Dendrobium do? It helps reduce your body weight, especially fat.

Canavalia Gladiata

Canavalia gladiata or simply known as the seeds of sword beans, is a type of extract that is commonly used for increasing the amount of ATP as well as a potent energy booster.

Psoralea Corylifolia

Psoralea corylifolia is another type of seed that is widely used in Eastern India specifically for weight reduction purposes. B4 Fat Burner contains this seed extract to help you lose weight fast.

Sophora Japonica

Sophora japonica is from a Japanese tree leaves that is said to help increase your body’s fat burning capacity, which leads to significant weight loss.

Other components of B4 Fat Burner include red wine concentrate and yohimbe (a type of bark). All ingredients are 100% natural.

B4 Fat Burner Reviews

Every time I take this supplement I get the energy I need for a long, hard workout. Too soon to know how the fat loss is going but the energy is good enough for me!
I didnt notice any loss of weight but it did help with energy. every time I noticed myself getting tired in the middle of the day I would take it and suddenly I wasnt tired anymore. It does NOT make you shaky and feel weird. It seems to have a nice balance of energy that you need to last you!

After reading several reviews of this product I believed that it would give me an energy boost prior to exercising. I know no pill will burn fat, exercise burns fat. These pills didnt give me any effect, no heightened alertness, no energy boost. I thought they were a waste of my money. None of the advertised effects happened to me.

This product did not work for me. I did not give me the energy or focus it claims. The one time I worked out really hard on it, I got terrible stomach pains after and I didn’t feel myself on it. Unbearable pain so I stopped using it. It could just be my body and what it can tolerate. I currently use Invincible from Nutrition Zone and it’s the best so far. I just wanted a fat burner along with energy and focus but this product didn’t do it for me.
I took these pills a directed and they led to a allergic reaction that included rapid heartbeat, hives, fever followed by chills, and vomiting. I flushed the rest of the bottle.
Terrible. Does nothing. Don’t bother. Not recommended. Waste of money. No effects. No weight loss. No energy. No better mood. Everything this claims it does is total nonsense

These reviews are from Amazon verified purchases. As you notice, there are people who are satisfied with B4 Fat Burner’s ability to increase energy.

But overall, there are a lot of testimonials which shows ineffectiveness in weight loss including some horrible side effects such as tingling, chilling, vomiting, allergic reaction, rapid heart beat, upset stomach, fever, hives and many others.

Directions of Use and Precautions

If you are under the age of 19 or if you are taking any types of medication or suffering from any type of disease, you have to consult your physician first before you take B4 Fat Burner.

    B4 does work. It might not work for everyone. I feel the enegry and I have lost 5lbs so far. I love the energy it gives you too because it’s not the jittery kind either. At first it did give me tingling of the skin and redness but that was the first pill I took and after that I was fine. 🙂

    B4 is terrible. I took it think I would have energy to workout, instead I felt like a crackhead. My head was hurting my hands started shaking. I had to just sit down for a moment. I went for a jog thinking I would feel better after I took it. Ha ! I felt just as bad. I thought something was seriously wrong with me. After drinking bottles of water I started to feel normal again. I wouldn’t recommend this to anyone. All of that just isn’t worth trying to burn belly fat.
