If you decided to try Raspberry Ketones you need to know they have side effects or not. First of all you need to act safe because it is your health we are talking about.

There are some facts what companies which producing and selling Raspberry Ketones saying:

 

What Are Raspberry Ketone Side Effects?
Many of the complaints you have heard are not about raspberry ketone side effects but side effects from other ingredients or other products or medicines you may be taking. Pure, natural raspberry ketone itself does not have side effects.  People only experience harmful or unexpected side effects when they choose a raspberry ketone product with other ingredients that come with risks.
Okay, so how do you make sure that a raspberry ketone product will work without causing problems? Watch out for the following red flags:
– Supplement Facts. Make sure you read the supplement facts label on the product… before you buy. If the company doesn’t list the supplement facts, that’s your red flag to leave them be.
– Dosage. Raspberry ketone is only proven to be effective in doses of 500 mg. Again, this should be on the label.
– Natural Ingredients. Lots of ingredients give you more, right? Depends. This could mean you’re getting ineffective doses of raspberry ketone because it’s crowded with other ingredients. Check the amount of raspberry ketone and make sure all the other ingredients are serving a purpose by being there.
– Blends. Again, check the label for “natural raspberry keytone.” If the label says it contains a “raspberry ketone blend,” this usually indicates that the raspberry ketone is synthetic because it is blended with other substances in a lab. A blend can still be effective as long as it contains the right amount of natural raspberry ketone.
And now – what other specialists saying about it:
Not included in the hype are the potential dangers of raspberry ketones. Because they regulate the body’s release of norepinephrine, it causes a spike in body temperature that may also lead to a temporary metabolic increase. Unfortunately, along with raising body temperature, norepinephrine can also raise blood pressure and heart rate. People with diabetes, heart conditions, high blood pressure, COPD, and asthma should all avoid raspberry ketones, which may aggravate the above conditions.

Raspberry ketones are said to be similar in structure to capsaicin (a natural chemical found to alter fat metabolism in several preliminary studies). Proponents claim that the compounds help trigger the breakdown of fat cells. However, there is currently a lack of scientific evidence to support the claim that raspberry ketones can promote weight loss.

Benefits of Raspberry Ketones for Weight Loss

So far, research on the health effects of raspberry ketones is extremely limited. While a small number of animal-based studies have tested raspberry ketones for their potential anti-obesity benefits, there are no clinical trials showing that taking raspberry ketone supplements can support weight loss efforts.

The available research on raspberry ketones includes a 2005 study published in the journal Life Sciences. For the study, scientists conducted several experiments that involved feeding raspberry ketones to mice. In one study, mice were fed a high-fat diet for six weeks. Then, for the next five weeks, the mice were fed the same high-fat diet enriched with raspberry ketones. Results revealed that the addition of raspberry ketones help reverse the weight gain induced by the high-fat diet. The study’s authors also found that raspberry ketones appeared to protect against the buildup of fat in the liver.

In a more recent study, researchers tested the effects of raspberry ketones on fat cells. Published in Planta Medica in 2010, the study found that raspberry ketones helped activate adiponectin (a hormone that regulates fat breakdown).

Are Raspberry Ketones Safe?

Due to a lack of scientific research, little is known about the safety of consuming raspberry ketone supplements in the long term.

However, since raspberry ketones are thought to stimulate the release of norepinephrine, there’s some concern that use of raspberry ketone supplements could be harmful to people with certain chronic conditions (including high blood pressureasthma, and chronic obstructive pulmonary disease). Norepinephrine is a type of nervous system chemical that is known to increase blood pressure.

There isn’t enough information available to know if raspberry ketone is safe to take as a supplement. Raspberry ketone has never been scientifically studied in humans to determine if it causes side effects. However, there are some concerns about the safety of raspberry ketone because it is chemically related to a stimulant called synephrine. Therefore, it is possible that raspberry ketone might cause feelings of jitteriness, increase blood pressure, or rapid heart beat. In one report, someone who took raspberry ketone described feelings of being shaky and a pounding heart beat (palpitations).

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of raspberry ketone during pregnancy and breast-feeding. Stay on the safe side and avoid use.
