What is Coenzyme Q10?

To start off with, Coenzyme Q10 is a pseudo vitamin and antioxidant commonly used to support heart health. Despite this main function, there are dieters who feel it can help them lose weight. You take it one or twice daily, in most cases.

There are a multitude of companies that sell Coenzyme Q10. Each claims the version they’re selling is the best to support heart health, however research tends to be completed on non-branded types. You can buy online from a long list of retailers, but there’s no official website for the ingredient. We like the clinical support it has and some users appreciate the results, but read on…

Increase in Energy – “Not Really”

Firstly, some users expected Coenzyme Q10 to boost energy, but they didn’t notice that effect. “If you take a supplement with one outcome in mind and that doesn’t happen, you are inevitably going to be let down,” explains our Research Editor.

“Not helping with my energy level,” said a customer.

“Instead of giving me a burst of energy and sense of well-being, I felt very strange and weak. Not my cup of tea I guess,” offered another user.

Just as many did notice a spike in energy after starting Coenzyme Q10.

One said, “This product has definitely increased my energy level. I have been able to exercise longer and as a result have lost weight.”

Another put it like this, “When she went to 3 pills per day, she felt more energized.”

Side Effects of Coenzyme Q10 – “Harmful or Mild?”

Quite a few Coenzyme Q10 side effects were reported by users. None appeared to be harmful – just irritating.

“This product gave me stomach queasiness and mild heartburn,” offered one dieter.

A customer said, “I started getting headaches and having stomach issues – upset stomach, cramping, etc.”

There are some positives out there from people who saw no such results.

“I have not had any side effects such as, headaches, dizziness, nausea, vision issues etc.,” was one experience.

Yet another shared, “I have noticed any side effects, nothing that I can tell or may have noticed at all so I guess that is good.”

We’ve noticed it takes something that seems quite small, like a headache, to ruin that chance of results you’re looking for. If Coenzyme Q10 side effects are irritating enough, it will pass from one dieter to the next as a warning of sorts.

The Science – “Does Clinical Proof Exist?”

Coenzyme Q10 is sold as a supportive supplement for heart health. This is a sensitive category. This antioxidant will NOT replace any medications prescribed by your doctor. With that said, some research suggests it may help in patients with heart failure as a low level is sometimes associated with the condition. There’s also some vague support for use with macular degeneration and aging. We also found a bit of information on using it for the treatment of obesity as a higher BMI is associated with lower levels of CoQ10.

What Users Are Saying

"”Great product made with quality, natural ingredients. I read reviews before purchasing and am very satisfied. I got it to help lower cholesterol and take it along with Pantathine . Going by my blood tests, it is helping.”"

"”So far this product has not had any unpleasant side effects; it will take time to determine whether it is helping with my health issues. Easy to swallow, no after taste.”"

"”After 3 day of taking your brand of CoQ10 240 SoftGels, I noticed I am getting more energy and feel less tired in the evening.”"

The Bottom Line – Does Coenzyme Q10 Work?

Are we heading out to the vitamin store right now? Well, we like the idea of adding Coenzyme Q10 to your supplement regime to support overall heart health. And, there is at least a small connection with weight-loss if you are obese. However, we are hesitant to give the green light as the proof is not as strong as it is with other, all-natural ingredients.

If you’re ready to lose weight and you want to try out a supplement, our suggestion is to go with one that’s directly connected to weight-loss via clinical testing, unlike Coenzyme Q10.

Among the best products we’ve seen this year is one called Dietspotlight . The label shows just four ingredients and all have been scientifically tested and shown to help spark metabolism. We found dieters all over the world reporting amazing results and side effects, of any kind, are few and far between.

Plus, you can try out Dietspotlight Burn as part of a Special Trial Offer because the makers are confident in the formula.

Coenzyme Q10

Q:
How long does it take for Coenzyme Q10 to lower blood pressure?
A:

Research of several clinical studies shows CoQ10 can lower blood pressure without significant side effects. After 4 to 12 weeks of use, one may see a decrease in systolic blood pressure by 17 mm Hg. Diastolic blood pressure may fall by 10 mm Hg

Q:
How much CoQ10 should you take a day?
A:

The amount of CoQ10 that the body produces declines with age, so dosage will depend on age. Everyone under age 60 should take 50-100 mg per day. Those who take a statin drug or are over age 60 should take at least 100 to 200 mg each day. Those who desire more support of the heart should take 300 mg per day.

Q:
What is Ubiquinol CoQ10 used for?
A:

CoQ10 is short for Coenzyme Q10. Body cells use CoQ10 to produce energy, but the body does not naturally produce it. It does produce Ubiquinol, which is a reduced form of CoQ10. Ubiquinol is more bioavailable than CoQ10 is and is therefore far better for your health.

Q:
Can CoQ10 cause nausea?
A:

Nausea is a side effect of CoQ10, as is upset stomach and vomiting. Because of this, those who suffer from stomach disorders should be cautious in its use. Other side effects that may be experienced are rashes, itching on the skin, and changes in blood sugar levels.

Q:
How does CoQ10 lower cholesterol?
A:

CoQ10 lowers cholesterol by protecting the LDL from oxidation. In addition to being an antioxidant, CoQ10 also improves heart health by rejuvenating mitochondria, the powerhouses of heart cells. Healthy hearts may also work to decrease blood pressure.

Q:
What is CoQ10 and what does it do?
A:

CoQ10, or Coenzyme Q10, is a substance that is made by the body. Like a vitamin, it is essential to your health. Every cell in the body needs CoQ10 to help produce the energy required to grow and maintain its operations. CoQ10 also stops molecules from causing oxidation that can damage cell health.

Q:
What is better: CoQ10 or Ubiquinol?
A:

Ubiquinol is a form of CoQ10. The common understanding is that Ubiquinol, compared to other forms, is eight times more absorbable. Another form of CoQ10 is Ubiquinone, and it is also absorbable and is a quality hydrosoluble.

Q:
Can CoQ10 cause diarrhea?
A:

Although Coenzyme Q10 is safe for nearly all adults, some may experience side effects of the digestive system, such as upset stomach, appetite loss, vomiting, nausea, and diarrhea.

Q:
Can CoQ10 give you a headache?
A:

CoQ10 may cause other side effects. Some users report flu-like symptoms. Others may experience a headache and dizziness. The supplement may also be responsible for insomnia, which can lead to fatigue and irritability.

Q:
What is in Coenzyme Q10 supplements?
A:

Supplements for CoQ10 are available in two forms. The active antioxidant form is Ubiquinol and the oxidized form is Ubiquinone. Ubiquinone will be converted (partially) to Ubiquinol by the body. These are meant to supplement the body’s natural production of CoQ10. Foods also produce CoQ10 naturally.

Q:
What is the best form of Coenzyme Q10?
A:

Ubiquinone and Ubiquinol are the two forms of CoQ10 available as supplements. Since Ubiquinol is what is naturally produced by the body, many companies advertise it as the better form. Ubiquinol prices tend to be higher than that of Ubiquinone.

Q:
Are CoQ10 and Ubiquinol the same?
A:

CoQ10 takes two forms in the body. The oxidized form is Ubiquinone. The body uses it and transforms it to Ubiquinone. Ubiquinone, the reduced form of CoQ10, works in the body and then, in turn, becomes Ubiquinol.

Q:
What are the health benefits of Coenzyme Q10?
A:

There are several health benefits of CoQ10 which is why doctors tend to recommend it. One effect is that it can enhance the functioning of the immune system. Another benefit of CoQ10 is that it can help fight fatigue by boosting energy. Taking CoQ10 can also benefit the users by treating high blood pressure and heart disease, and by reducing cholesterol levels.

Conenzyme Q10 - What You Should Know

Coenzyme Q10 is a co-enzyme the body needs to function correctly. The body produces it on its own to play a role in many processes. As we age though, our bodies stop making enough CoQ 10 to operate at the best levels. This is why many people look to supplementation to ensure they are getting what they need. We will take a closer look at the coenzyme to help you determine if it is something you should be using to promote more weight loss.

List of Ingredients

Coenzyme Q10 is the ingredient. It is used in a variety of supplements, so we advise you to take a closer look at the supplement you are most interested in to ensure it has what you are looking for.

Product Features

A coenzyme works with an enzyme in the body to help it perform certain functions. It is basically a protein that works to increase the rate chemical reactions take place in the body. CoQ10 works to provide energy for cell growth and reproduction, and behaves like an anti-oxdiant to reduce free radicals in the body. Free radicals lead to many conditions in the body, including cancer. This is why CoQ10 may be an effective cancer treatment.

Coenzyme Q10 - Advantages

  • Coenzyme Q10 helps keep the body healthy.
  • CoQ10 is available in several supplement forms.

Coenzyme Q10 - Disadvantages

  • Coenzyme Q10 has nothing to do with either appetite suppression or thermogenics.
  • Though no serious side effects have been reported, some may experience: insomnia, abdominal pain, and nausea.
  • Those who take insulin and some blood clotting drugs should speak to a doctor before taking this supplement, as it may interfere with the way the body responds to it.
  • Many healthy people who follow a balanced diet will not need to supplement with this as their body will produce enough of the chemical on its own.
  • Depending on the supplement manufacturer, there may or may not be a money back guarantee available.
  • There are likely no free trials of this supplement available.

Conclusion

Coenzyme Q10 is beneficial to the body in helping it stay healthy and fight free radical damage, but it does not play a direct role in the loss of fat or the suppression of appetite. Most people will produce enough of the protein on its own, and therefore will not require supplementation. If you think CooQ10 will be something good for you, speak to your doctor to be sure it will not interact with any medications you may be taking. Otherwise, look for a weight loss supplement that contains proven ingredients in the right amounts to suppress the appetite or burn fat, and use it with a balanced diet and regular exercise.
