I'm just learning about bitter orange extract and that supposedly it ia a great fat burner and appetite suppressant. It's pretty cheap; 10 Grams Synephrine HCL 99% (Bitter Orange Extract) (Citrus Aurantium Extract) Bulk Powder . But I still like to hear some people's experiences with it before I took the plunge. From what I read, it says there are no bad side effects. Is this true???

Hi Kaela- I've taken it in the past, really like it as an alternative to fat burning pills which have always given me negative side effects. I've taken bitter orange with Octopamine HCL and had great results. I've also heard of combining Yohimbine with bitter orange although I've never tried that. But yes it's a good fat burner and does help to curve your appetite, in my experience.

Just be careful! Synephrine is a close relative of, and acts in the body like, pseudoephedrine (the main component in methamphetamine, which is why you have to ask at the pharmacy to get Sudafed) and epinephrine (adrenaline). All these are good for energy and appetite control and have been used for weight loss effectively, but they can be he11 on the heart. Just because somebody uses the name of a plant they extract it from and calls it natural doesn't make it safe. Remember, cyanide can be from "all natural peach and apricot pits" and it's still a deadly poison. "Natural" isn't a synonym for "safe."

The side effects are pretty much the same as from epinephrine or pseudoefedrine, and vary with how sensitive you are to these drugs. They might make you more energetic, or they might cause heart palpitations, sweating, a racing pulse, etc. And NEVER take more than the recommended dosage under any circumstances.

USDA organic coconut oil has been shown to speed up metabolism In my own life I have lost weight on it, seems to work on acne and other things also. and the only time I lose weight is when im sick and then once im better the weight comes right back on but since I started eating coconut oil and using it as a butter replacement it does seem to help. For it to be "safe for human consumption" you need to get the organic kind as the regular has to many chemicals in it that will make you not healthy. also as its 120 calories per table spoon it will curb appetite and in my case of always eating later it seems to have regulated my appetite to more normals levels. I'm hungry when I'm supposed to be and I don't feel the urge to snack every 10 mints.
it goes right to the liver for energy so if you notice a energy kick when you eat it that is very normal.

Because the liver metabolizes substances we ingest. Thus the posters statement "it goes right to the liver for energy so if you notice a energy kick when you eat it that is very normal." is accurate. Source "Brunner and Suddarth's Textbook of Medical-Surgical Nursing"

I tried it, and it works to some extent, however it's not tonic; meaning it's not something you can take everyday otherwise it may have some serious side effects. A great book that compiles all the foods that are legitimately beneficial for weight loss and can be taken everyday is Lose the Fat by Eating More. 10 Plant-Based Fat Burning Foods that Will Turn Your Life Around

I just heard about bitter orange. My Naturopathic doctor suggested I take it to open my bronchial tubs.

The problem with these pills, aside from the side and long term effects is that once you start taking them, you can't stop. Once you stop, you start gaining weight. A simple way to suppress your appetite is to do something physical for about 5 to 10 minutes. Lift some light weights, go for a short walk, and drink a glass of water. That should hold you over till meal time. Also keep healthy snacks around. The combination of both usually works. And try to stay away from sugar early in the day. When the sugar high wears off, you'll start craving more sugar.

This is only partially correct. It is only m-synephrine that impacts the receptors involving heart rate and blood pressure. The isomer found in bitter orange, p-synephrine, does not impact the cardiovascular system, but does have a modest impact on resting metabolism. There are many articles on PubMed based on human clinical trials which elucidate this point. According to the National Institute of Health, bitter orange is a safe supplement.

Have not tried bitter orange. After reading info, I will not be trying it.

One friend who has maintained her weight for years, credits taking one cayenne pepper capsule daily to her successful weight maintenance.

I use organic coconut oil. I have not seen any weight loss benefits personally, but I do like the product.

I tried Bitter orange in the past and found that at the levels I had to use, I got awful side effects. Yes, synephrine can raise your blood pressure, i would not say its related to methamphetamine any more than anybody's favorite methylxanthine (coffee) is. Any how I did get some bad side effects from increased BP with levels greater than 250mg - I got some horrible headaches and pulsing in my ears. I actually thought I was allergic to it as a result. A friend had been using the Liporidex max and lost 8 pounds in a week so of course I wanted to try it, but was disappointed when I saw that it had bitter orange in the formula. After doing some more research and calling the company to see if they would tell me how much bitter orange was in there (they would not, but said its less than 100mg?), a gave it a go. Either way, I had great results. So for me bitter orange worked in combination with other stuff, but on its own - it was a no-go. Ultimately adrenaline analogs like bitter orange, dmaa/e are great for the metabolism, but of course come at a cost. You cant have your cake and eat it too...unless you combine your pures.

Great reply. There appears to be some confusion about the difference between p-synephrine and m-syenphrine. The FDA actually acknowledged their initial warnings as a mistatement regarding Bitter orange extract. Here's a great article on the topic:

Please Google Bitter Orange for many serious side effects, even death. Similar to Ephedra, & being replaced in some weight loss products.

From what I found from researching Bitter Orange, side effects can be many & serious. Your headaches could be one of then, high blood pressure.

Most of what's out there is the regurgitation of the same misstated findings by the FDA. Bitter orange extract has been proven to be safe. Read here:

I buy a lot of stuff online and I've never wrote a review before but I feel so compelled to do so after the side effects that I've had after having taken only HALF the recommended dosage of Maxitone Sculptress 'food supplement' tablets. I found that my heart was racing uncontrollably and I struggled to breathe. This lasted for around an hour and left me really shaken up. After having researched the ingredients online I found that there is a lot of disagreement over whether or not these are safe and all advice seems to suggest that combining them with caffeine is a bad idea - the exact cocktail of ingredients provided in this 'natural' product.

Seeing as Maxitone is a well known brand and sold in Boots/Amazon etc I didn't even think to question its safety...

A quote from this article... 'The F.D.A. does not require manufacturers of dietary supplements to prove that the products are safe and effective before they are sold.'

Something else I read online... Because bitter orange contains chemicals that may speed up the heart rate and raise blood pressure, it may not be safe to use as a dietary supplement. There have been reports of fainting, heart attack and stroke in healthy people after taking bitter orange supplements alone or combined with caffeine.

I opened a bottle today. They smell funny. A little like urine. Is it just me? Maybe I got a bad bottle of bitter orange tablets?

While the supplement you mention does contain bitter orange, it also contains the equivalent of more than 4 cups of coffee in each dosage, along with another stimulant called Guarana. It is possible (from my experience it is highly likely) that your experience has absolutely nothing to do with bitter orange.

Thank you. You are using logic that many of these posters are ignoring. Even many drugs that are regulated cause some people to have bad side effects. People need to use caution and find out which specific ingredients they have good or bad reactions to. The use of plants as medicine is ancient and merits each persons attention and experimentation to learn to take responsibility for our own health. Of course, exercise and a healthy diet is the first place to start :)

Hi. My experience with bitter orange was with the diet pills Jadera. Super effective but yes...serious side effects for me personally. I had them all... headaches, racing heart rate, high blood pressure, sweating. Even losing 12 pounds under two weeks I had to stop taking them. But I think that is because of the high dose of caffeine. I'm trying bitter orange by itself as a test to see if I will experience any side effects! We shall see...I will keep you posted.
