What is Cordyceps?

Firstly, Cordyceps mushroom is a fungus that is found on specific caterpillars located in the mountainous regions of China. This is difficult to find in large enough quantities to market, but it is reproducible in laboratory settings. It has been used to treat upper respiratory ailments, dizziness, irregular heartbeat, increased energy, and a variety of other health issues. Some of the more recent research has focused on a link between the ingrediennt and reversing insulin dependence which can lead to weight-loss.

Cordyceps supplements are made by several different companies. As the demand for the fungus increased, so did commercial production. Products are more readily available now at a significantly lower cost than in past years when supply was based on gathering it from the mountains of China, but read on…

Side Effects – “An Issue?”

Our first concern is with Cordyceps side effects. Mild ones have been reported, but so have some that are more concerning. According to our Research Editor, “It is important that any noted reactions associated with a nutritional supplement be relatively harmless. There are too many people who begin taking all natural products thinking they will be completely safe and this is simply not always true.”

One unhappy reviewer said, “I thought something used in Traditional Chinese Medicine would be worth trying but I broke out in an awful rash that lasted for days.”

Another was concerned about the new sources of Cordyceps saying, “I’ve used Cordyceps in the past but I got it from a reputable establishment in China. What I bought recently was much cheaper but I had more side effects with it.”

Some had consumers had more positive experiences. One customer said, “I feel like I had more energy when I take Cordyceps which makes it easier for me to work out.”

Another claimed, “I started taking Cordyceps along with a few other supplements. My energy and mood increased and I’ve steadily been losing weight.”

Lack of Proven Cordyceps Benefits – “Not Specific Enough”

Another concern we have is that the research done has not been targeted specifically at the weight-loss functions of the fungus.

One consumer said, “I contacted the manufacturer of the Cordyceps supplement I use to find out where their research came from but no one could tell me.”

Another explained, “I looked into the research before I made a purchase but I couldn’t find anything so I’m waiting to talk to a TCM practitioner before I make a decision.”

Others were more understanding about the lack of western research. One claimed, “My family is from China and we have been using Cordyceps for generations, it’s very good.”

Another said, “I have used this off and on my whole life for a variety of issues. It works if you know what you’re doing.”

According to our research, if a product has significant side effects or if the scientific research doesn’t support the claims the chance of long-term results is minimal. If Cordyceps just isn’t effective for weight-loss, the ingredient may not be the best choice.

The Science – “Need More Clinical Support?”

At DietSpotlight, we need to see reliable scientific proof that a supplement is safe and effective. We have seen some interesting preliminary studies and recognize that Traditional Chinese Medicine has a lot to teach the western world. However, more research and documentation is needed to explore how this fungus can help support a healthy weight.

What Users Are Saying

"”I am satisfied with the product.”"

"”These are very effective and give me a great energy boost; I find the price quite high for a month’s supply.”"

"”One week and NO results.”"

The Bottom Line – Does Cordyceps Work?

Should I race out for a bottle of Cordyceps? If you have access to a quality distributor it could be an interesting addition to your health plan. However, there is simply not enough scientific evidence at this point to support the broad claims many companies are making. This is why we are skeptical about giving it our support.

If you want to drop those extra pounds why not try a supplement that has tested ingredients that are backed by solid scientific research. A really good supplement will be able to explain the function of the formula and provide safety information about the product.

Among the best products we’ve seen this year one of the best is called Dietspotlight Burn. It’s made of a combination of four key ingredients, which have been shown in documented clinical research to help increase fat loss and metabolism. Our research didn’t dig up any negative online reviews but it did discover a number of happy dieters who were sharing their great results.

The makers of Dietspotlight Burn are so confident that their product works as advertised that they’re offering a Special Trial Offer, which we find reassuring.
