Brand: PrimaForce | Capsules: 180 | Serving Size: 1 Capsule

PrimaForce's Syneburn Supplement is described as a weight loss supplement thanks to its 10mg of synephrine, the main extract from bitter orange, which is said to increase energy expenditure and act as a mild appetite suppressant according to the National Institute of Health.


As a result, adding these capsules to your diet may increase your resting metabolic rate and energy expenditure, one of the standout benefits associated with bitter orange.

Moreover, with PrimaForce's Syneburn Supplement, you get 180 capsules for a relatively inexpensive price.

Brand: bulk | Capsules: 90 or 270 | Serving Size: 3 Capsules

Unlike some of the best beef liver supplements, bitter orange is a completely vegan compound in its pure form, giving way to vegan-friendly supplements such as bulk Complete Thermogenic.


In each capsule, you get nine active ingredients in total, including citrus aurantium, with the supplement tailored toward helping you stay alert and focused during a workout.

That said, bulk describes its tablets as potent and, therefore, might not suit everyone and should be taken sparingly in our opinion.

However, if you're looking for an alternative to one of the best pre-workouts, for instance, then this bulk Complete Thermogenic could be the supplement for you.

Frequently asked questions about bitter orange supplements

Finding which supplements to add to your diet can be a little confusing at times. Don't worry though because we've answered some of the most frequently asked queries surrounding bitter orange supplements right here.

What do bitter orange supplements do?

Bitter orange is perhaps most commonly known for being one of the traditional ingredients in marmalade. However, you'll also find it has a long history in alternative medicine, particularly in Southeast Asian culture.

More recently, bitter orange has been used to create herbal weight loss supplements because P-synephrine, an active ingredient in bitter orange, is similar to the compound ephedrine. Ephedrine has been linked in research by Shannon et al. to weight loss due to increasing an individual's metabolic rate.

However, weight loss isn't the only potential effect bitter orange has. Like other citrus fruits, bitter orange contains limonene, a substance that has anti-inflammatory and antiviral properties according to research by Meeran et al..

Therefore, bitter orange may aid your post-workout recovery as well as help you fight off diseases alongside, especially as it also contains vitamin C.

Should you take bitter orange supplements?

Bitter orange supplements aren't as widely researched as say, for example, the best creatine supplements around. As a result, choosing whether or not you should add bitter orange to your diet will come down to your own personal preference.

This is because the overall safety of bitter orange extract is not widely agreed upon. That said, several studies, including one of particular note by Shara et al., deem bitter orange extract safe for use in dietary supplements and foods at the commonly used doses despite concerns over it increasing heart rate and damaging the nervous system.


In terms of who should take bitter orange, well those who might be looking to lose weight may see some benefit in adding bitter orange to their diet. However, it's important to consume a relatively regular diet with the supplement rather than going too far into a calorie deficit.

It may also be beneficial for those who train regularly or athletes looking to improve their recovery and reduce any potential soreness post-workout due to its associated anti-inflammatory properties.

Is bitter orange considered a stimulant?

There is conflicting information surrounding whether synephrine, one of the main compounds in bitter orange, should be considered a stimulant.

A stimulant is described as a substance that raises levels of physiological or nervous activity in the body. Research from Bui et al. suggests that bitter orange raises both blood pressure and heart rate and, therefore, could be deemed as a stimulant.

In fact, the National Collegiate Athletic Association lists synephrine as a stimulant and is, therefore, banned in athletic competitions.

However, several studies, including one by Stohs et al., deem bitter orange safe with no serious adverse effects. As a result, it isn't overly clear whether bitter orange is a stimulant or not based on current research.


How much bitter orange can you take?

The National Center for Complementary and Integrated Health (NCCIH), a US government agency that explores complementary and alternative medicine, believes bitter orange is likely safe to consume orally in amounts commonly found in foods.

This is supported by research from Kaats et al. which found no adverse effects of bitter orange in doses up to 98mg during the 60-day trial period.

With this in mind, it would seem it's relatively safe to consume up to 98mg of bitter orange a day as part of your diet.

Make sure you don't go overboard though because, as touched on above, there are some associations that deem bitter orange to be a stimulant and, in turn, have a significant impact on your heart and cardiovascular health.
