Raspberry Ketone has been classified by the FDA as safe in small quantities as a food additive. Although the amount of Raspberry Ketone is likely to be a lot higher in the diet pill than in food to which it is added, we can still assume it is relatively safe.

What Are The Side Effects of Raspberry Ketone?
You might have heard a lot about raspberry ketones having side effects but the reality is that raspberry ketone supplements are one of the best weight-loss supplements causes very little or no side effects at all. For those thinking of great weight-loss with little or no side effects should definitely go for raspberry ketones cause they provide the best means to aid you in trimming your body for a perfect shape that you desire. But it is also true that excess of everything is bad so over-dosage should be avoided no matter what.
Some of the few side effects caused by extremely excess over-dosage of rapsberry ketones are:
Increases Triglyceride Levels
Some of the clinical researchers have found that excess of raspberry ketones intake can cause an increase in Triglyceride level in the blood that results from mobilization of the fatty acids from fat stores of the body. This generally causes temporary acidosis and decreases the PH of blood by only a slight amount. This is usually normal but to prevent adverse changes being causes in the body, it is recommended not to go beyond normal dosage values.
- Cardiovascular Complications
Since raspberry ketones appear to have some chemical similarity to synepherine, be careful if you have high blood pressure or heart conditions. Synepherine might raise blood pressure and heart rate.
There have been some anecdotal reports of jitteriness, rapid heartbeat and increased blood pressure. In one report, someone who took raspberry ketone described feelings of being shaky and a pounding heart beat (palpitations).
- Worsen Estrogen Caused Cancer
Some have speculated that raspberry ketones may be inappropriate for those with cancers that are sensitive to estrogen levels. This is based on concern that raspberry ketone may have estrogen -like properties. Cancers that might be affected by this include breast cancer, fibroids of the uterus, endometrium cancer and uterine cancer. When in doubt, ask your doctor or pharmacist about raspberry ketone supplements if you have a history of any type of cancer.
- Interaction With Diabetes
Raspberry ketone may lower blood sugar levels, and decrease the risk of bleeding. So, people taking drugs for diabetes should be monitored closely by their healthcare team.
- Nervous Effects
Some people can take raspberry ketone supplemets 10 times a day without unpleasant side effects. Then others can take it one time and feel jittery with a noticeably higher heart rate and possibly upset stomach. Clearly, some people are more sensitive to stimulants.
Common effects include increased anxiety, shaky and jittery hands, tremors and profuse sweating.
- Increases Norepinephrine levels
Raspberry ketone increases norepinephrine levels and this is what can produce discomforting side effects in some users. Norepinephrine is a neurotransmitter that increases heart rate among other effects. The term is often used interchangeably with noradrenaline or adrenaline. Norepinephrine can also be given as a drug that will increase blood pressure.
The flight-or-flight response is well known, and norepinephrine is the primary stress hormone involved in the process. Along with increased heart rate, other effects include increased blood flow to muscles while producing more glucose (blood sugar) availability. It is the latter effect that should be noted by diabetics.
- Interaction with liver function
A study conducted in rats noted that 1-2% of the diet as raspberry ketone was able to attenuate increases in liver fat associated with a high fat overfeeding diet, with the 2% group not being significantly different than control and decreases in liver triglycerides and cholesterol were noted with normalization of serum HDL-C and LDL-C. Liver enzymes were greatly influenced.
- Interaction with Medical Conditions
The potential side effects of raspberry ketone must be considered by people taking medication for heart disease, diabetes, anxiety conditions, asthma and certainly other conditions. Other serious concerns are drug interactions with prescription medication for the above conditions and those for regulating hormones and heart rate.
People with existing medical conditions are strongly encouraged to consult with their physician before taking any weight loss supplement containing raspberry ketone.
