Green coffee bean extract is the natural weight loss supplement that’s making waves at the moment, with studies suggesting it could help you slim down without making drastic changes to your diet and lifestyle. Of course, the first question that’s likely to be on your lips is, ‘does it really work’, closely followed by ‘are there any side effects’?

There have recently been reports of people experiencing minor stomach cramps after using a particular brand called Ultimate Green Coffee Bean. It’s important to bear in mind that no product is likely to be completely free from side effects. Also, it’s not yet clear what might be causing the side effects of green coffee bean extract with this brand. They might not even be due to the green coffee bean extract itself, as fillers or other ingredients could be to blame.

What Exactly is Inside Green Coffee Supplements?

Green coffee bean extract is derived from coffee that hasn’t yet been roasted. It is rich in antioxidant compounds called chlorogenic acids, which are thought to be behind the extract’s beneficial effects. More research is needed on chlorogenic acid and green coffee beans in general, but it is thought that the chemical affects the body’s metabolism and the way it handles blood sugar.

What Does Research Tell Us About Green Coffee Side Effects?

There has only been limited research on pure green coffee bean extract side effects, but the evidence so far suggests it is safe. There have been no serious side effects reported in clinical studies to date. One study published in the Journal of International Medical Research in 2000 used a high-quality green coffee bean extract called Svetol and found it to be well tolerated and effective. Another more recent study, published in 2012 in the journal Diabetes, Metabolic Syndrome and Obesity, also reported no adverse effects among green coffee bean extract users.

You might also be interested to know that celebrity medic Dr. Mehmet Oz has conducted his own study with green coffee bean extract, inviting his entire studio audience to take part. Participants gave a resounding ‘no’ when asked if they’d experienced any negative side effects of green coffee bean extract during the two weeks in which they used the supplements.

Low-Caffeine Svetol Reduces the Risk

You should bear in mind that green coffee bean extract does contain caffeine, which can cause side effects such as insomnia, nervousness, stomach upset and nausea. However, some green coffee bean extracts – including Svetol, which is recommended by Dr. Oz – only contain a small amount of caffeine, making green coffee side effects unlikely if you choose your supplement brand wisely.

Our advice is that, from the limited studies that have been carried out, green coffee bean extract side effects appear to be minor and uncommon. More research is needed to confirm its safety, however, particularly in pregnant and breastfeeding women. For this reason, we’d advise you not to use green coffee bean extract if you’re pregnant or breastfeeding. There also haven’t been enough studies done in children to confirm its safety.

If you do decide to try green coffee bean extract, make sure you do your research and choose a quality product. Dr. Oz recommends choosing a brand that contains at least 45% chlorogenic acid and is free from filler ingredients, which could be responsible for some of the reported side effects of green coffee bean extract. If you follow these tips and take the recommended dosage, you hopefully won’t experience any worrying side effects with green coffee supplements.
