Raspberry ketones give raspberries their signature scent. They have become a popular supplement in recent years as they appear to regulate the way the body processes sugars and fat making them a likely candidate for weight loss.
What is Raspberry Ketone?
Raspberry ketone is naturally present in a variety of red berry fruits (including raspberries - as the name suggests). The chemical composition of raspberry ketones appears similar to capsaicin (the compound that makes peppers spicy hot). Capsaicin is thought to lower blood cholesterol levels and is known as a powerful antioxidant. Raspberry ketone may act similarly.
Why do I need Raspberry Ketone?
Animal studies and tests on isolated cells in test tubes have shown that raspberry ketone improves insulin sensitivity and reduces fat in the liver.* It’s thought raspberry ketones may help weight loss by increasing levels of a hormone called adiponectin which regulates the metabolism of fat and glucose in the body enabling fat to get broken up more effectively so that it is easier to burn off.
Raspberry ketones may have other benefits too - in a small Japanese study*, people with hair loss who rubbed raspberry ketone lotion on their scalps saw some growth, while women who applied the lotion to their faces reported improved skin elasticity.
Can too much Raspberry Ketone be bad for you?
The recommended dose for weight loss is between 100-300 mg daily. As raspberry ketones resemble other stimulants there is the potential for jitteriness and palpitations.
