In some cases, doses may be gradually increased to 3000 mg per day. For heart failure and fluid build up in the body (congestive heart failure or CHF): 30 mg once daily, or up to 300 mg per day divided into two or three doses for up to 2 years. Also, 2 mg/kg daily for up to one year has been used.
Answer: Studies with CoQ10 have not shown serious adverse effects at moderate doses even when taken for several years — although it may be best to divide the dose over the course of the day.
If you have been taking CoQ10 supplements while trying to conceive or through fertility treatments, we recommend stopping as soon as you are pregnant UNTIL you discuss it with your doctor.
Typically, 90–200 mg of CoQ10 per day are recommended, though some conditions may require higher dosages of 300–600 mg. CoQ10 is a relatively well-tolerated and safe supplement that may benefit a wide variety of people looking for a natural way to boost health.
Plasma CoQ10 levels were significantly increased following 2 weeks of CoQ10 supplementation (p < 0.001); while a trend for higher muscle CoQ10 levels was observed after acute CoQ10 ingestion (p = 0.098).
Due to it's antioxidative effects, research has found that CoQ10 reduces inflammation in the body. This is significant because so many diseases are caused by inflammation. We are realizing that inflammation is often due to our poor health habits, insufficient sleep, and… you guessed it – lack of nutrients!
Safety. No serious side effects of CoQ10 have been reported. Mild side effects such as insomnia or digestive upsets may occur. CoQ10 may interact with the anticoagulant (blood thinner) warfarin and the diabetes drug insulin, and it may not be compatible with some types of cancer treatment.
While most people tolerate coenzyme Q10 well, it can cause some mild side effects including stomach upset, loss of appetite, nausea, vomiting, and diarrhea. It can cause allergic skin rashes in some people. It also might lower blood pressure, so check your blood pressure carefully if you have very low blood pressure.
CoQ10 supplements aren't necessary for everyone. “If you have a balanced diet, and if you're young and healthy, you probably have enough CoQ10 in your body,” Peart says.
CoQ10 positively influences the age-affected cellular metabolism and enables to combat signs of aging starting at the cellular level. As a consequence topical application of CoQ10 is beneficial for human skin as it rapidly improves mitochondrial function in skin in vivo.
Fatigue and muscle weakness are signs of a slight CoQ10 deficiency. As mentioned previously, it's unlikely that the general population will experience CoQ10 deficiency; however, in individuals with specific health conditions such as genetic mutations, diabetes, or cancer, there is an increased risk.
CoQ10 is safe for most people after the age of 18 and is encouraged for anyone with mitochondrial dysfunction, over the age of 35, or anyone trying or planning to conceive.
In addition to reducing the risk of cardiovascular problems in patients with liver disease, CoQ10 supplementation may also benefit the disease process within the liver by reducing inflammation and oxidative stress.
In the CoQ10 groups, the adverse events leading to withdrawal that were judged to have a possible relation to the study drug were nausea, abdominal pain, or vomiting (2 participants); diarrhea; worsening depressive symptoms; palpitations; constipation; insomnia; and dizziness.
If you eat sources of saturated fat, like beef, switching to foods with omega-3 fatty acids, like fatty fish, can help lower your heart disease risk. CoQ10 may offer benefits if you already struggle with cardiovascular disease risk or you've had a heart attack.
For our patients, daily supplementation of CoQ10 can lead to doubling their weight loss over several months with the same calorie intake. Also, CoQ10 improves stamina and motivation to exercise, which further helps to achieve an optimal weight.
Answer: Yes, it is possible that CoQ10 is making it harder for you to fall asleep. Fortunately, there are ways to minimize this effect. Learn more in the Concerns and Cautions section of the CoQ10 and Ubiquinol Supplements Review.
Preclinical and clinical studies have shown that CoQ10 has anti-inflammatory and antioxidant effects, and effects on mitochondrial dysfunction, which have been linked to the inflammatory response.
Similarly, CoQ10 supplementation improves glycaemic control and vascular dysfunction in type II diabetes, improves renal function in patients with chronic kidney disease, and reduces liver inflammation in patients with non-alcoholic fatty liver disease.
Drug Interactions and Additive Effects
On the other hand, some studies have shown that CoQ10 has done the complete opposite to Vitamin K Antagonists and actually enhanced the anti-blood-clotting effect, which leads to excessive bleeding.
The findings showed that taking CoQ10 by patients with CAD significantly decreased total-cholesterol (SMD -1.07; 95% CI, − 1.94, − 0.21, P = 0.01) and increased HDL-cholesterol levels (SMD 1.30; 95% CI, 0.20, 2.41, P = 0.02).
Coenzyme Q10 (CoQ10) is a popular nutritional supplement, an antioxidant and an essential component of the mitochondrial electron transport chain. Several clinical studies have suggested that fatigue can be reduced by antioxidant supplementation.
Many cardiologists place their patients on CoQ10 to help cardiac function as well as to reduce the bad side effects of statin cholesterol drugs. The supplement also may help decrease the pain of rheumatoid arthritis by decreasing the bad inflammatory chemicals that lead to cartilage breakdown.
No interactions were found between caffeine and CoQ10.
