Sure we have all heard of coffee, but have you heard of green coffee? However, green coffee refers to raw coffee beans from coffee fruits that are yet to be roasted. Also, skipping the roasting process helps green coffee retain most of its chlorogenic acid content, a beneficial antioxidant compound [1].
Besides green coffee beans can substitute usual coffee beverages, they are more popularly consumed as dietary supplements. That being the case, dietary supplements with green coffee bean extracts have more chlorogenic acid-related benefits, such as promoting weight loss and minimizing the risk of developing chronic health conditions.
We’ll take a look at some of the best green coffee supplements available on the market!

How to Choose the Best Green Coffee Supplements
Chlorogenic Acid Content & Product Dosage
Chlorogenic acid is essentially the active ingredient in green coffee supplements. So, it’s best to choose products with 50% chlorogenic acids, the maximum potency level.
Since the optimal dosage of green coffee supplements is not standardized. Also, experts suggest dosages between 240 to 600 mg per serving for a 50% chlorogenic acid supplement to be sufficient.
Even so, the best practice is to consult your healthcare provider beforehand to discuss the suitable dose of green coffee bean extract supplements for you.
Pill Size
Supplements with larger doses usually come in larger sizes. Therefore, it’s essential to know the most suitable size for yourself as uncomfortably large sizes may be difficult to swallow.
Besides, soft gel capsules are easier to swallow compared to tablets. This is because soft gel capsules are coated with gelatin, giving it a smoother surface coat that’s easier to slide down your throat and swallow.
So, if this is your first time taking supplements or you have known swallowing difficulties (dysphagia), choose green coffee soft gel capsules that come in small doses.
Caffeine Content
The typical amount of caffeine in green coffee supplements is 20 to 50 mg per capsule. Also, higher doses of caffeine are associated with a greater extent of stimulatory side effects (restlessness, agitation, headache, or sleep disturbances).
If you’re looking to avoid these side effects, look for green coffee supplements that are either decaffeinated or low in caffeine.
Brand Reputation
Since a brand’s reputation reflects the quality of its products and its standing amongst consumers. Moreover, prescription medications, vitamins, and supplements do not undergo rigorous FDA approval and quality control processes before marketing 4.
That being the case, information such as brand reputation is essential to ascertain if the product ingredients are pure and safe to use. Always keep an eye out for news or reports on red flags such as poor manufacturing facilities, unhygienic packaging, or product defects.
Precautions and Side Effects Of Green Coffee Supplements
However, unroasted coffee beans contain naturally-occurring caffeine. Since caffeine is a stimulant ingredient, it may cause side effects such as agitation, headache, sleep disturbances, gastric distress, or vomiting. While it’s worth noting that no significant adverse effects have been reported in most human trials studying the safety of green coffee supplements.
Apart from that, the safety of green coffee supplements is not established, and therefore not recommended for:
- Pregnant or breastfeeding women
- Children under the age of 18
- People diagnosed with liver or kidney disease
- Individuals taking medications (i.e., stimulants, blood thinners, etc.) that may interact with green coffee supplements [5]
- Individuals taking herbal stimulants or other supplements containing caffeine
For this reason, you should consult your healthcare provider to discuss the suitability of consuming green coffee supplements if you fall under any of these categories.
Bottomline: Best Green Coffee Supplements
Green coffee supplements are advertised for reducing body fat, general health, blood glucose level control, and many more. While all those benefits of green coffee sound promising, do remember that green coffee is a relatively new discovery in the world of complementary medicine.
More research and studies are still underway to understand the potential benefits of green coffee bean extract in improving the quality of our lives. For that reason, you should do your own research and background study before deciding to try out this supplement.
