Raspberry ketones have gained popularity in recent years as a weight loss supplement, but what exactly are they and how do they work? Raspberry ketones are a natural compound found in red raspberries that give the fruit its distinct aroma. While they’re often marketed as a quick fix for shedding pounds, there’s little evidence to support these claims.
Despite this, many people continue to use raspberry ketones in their weight loss regimens. So what’s the truth about this trendy supplement? Let’s dig a little deeper to find out.
What do raspberry ketones do?
Raspberry ketones are often marketed as a weight loss supplement and are believed to have several potential benefits for weight management and metabolic health. Some of the potential benefits of raspberry ketones include:
Increased adiponectin production
Raspberry ketones are believed to increase the production of adiponectin, a hormone that helps to regulate metabolism and blood sugar levels. Increased adiponectin levels may help to promote weight loss and improve insulin sensitivity.
Reduced fat accumulation
Some studies have suggested that raspberry ketones may help to reduce the accumulation of fat in the liver and other tissues, which could further support weight loss and metabolic health.
Antioxidant and anti-inflammatory properties
Raspberry ketones may have antioxidant and anti-inflammatory properties, which could help to protect against oxidative stress and inflammation, two factors that are believed to contribute to a range of chronic diseases.
Improved exercise performance
Study published in Life Science has suggested that raspberry ketones may improve exercise performance by increasing the breakdown of fat cells and providing the body with additional energy.
How to take raspberry ketone
Raspberry ketones are usually taken as a dietary supplement in capsule or tablet form. The recommended dosage varies depending on the specific product, but generally ranges from 100-400 mg per day.
Raspberry ketones can be taken with or without food, but it’s typically recommended to take them with a meal to aid in absorption.
What is the recommended dosage of raspberry ketones?
The optimal dosage of raspberry ketones can vary depending on factors such as age, weight, and overall health status.
However, most supplements recommend a daily dosage of 100-200mg of raspberry ketones, typically divided into two or three doses throughout the day.
