Uni Key Review - Do These Weight-Loss Supplements Work? Are side effects and ineffectiveness deal breakers?

Editor's Review: 3.5 / 5.0
Uni Key Review

I’m obsessed with finding diet products that actually work. Let’s find out if Uni Key is one of them. In our review we’ll concentrate on ingredients, side effects, clinical research and quality of customer service. Furthermore, we’ll pick apart hundreds of comments and experiences. Then, we’ll summarize and condense to give you the info you need.

EDITOR'S TIP: Substitute Uni Key with a proven fat burner such as Leptigen for better results.

What is Uni Key?

First off, Uni Key is a line of dietary supplements containing caffeine, ginkgo biloba, bilberry, pea and rice protein, l-carnitine, chromium and green tea, among others. The recommended serving depends on the product, but typically you will use them once or twice per day, which is supposed to support overall health. One benefit is the variety available on the official website.

The brand, which was introduced as a line of health and wellness supplements in 1992 by Unikey Health, does not appear to use synthetic ingredients, impressive. The products are available to purchase online and through some outside retailers. We like that the company has a strong foothold in the industry and that some of the formulas are all-natural, but read on…

Side Effects – “Do You Need to Worry?”

The first concern we came across about Uni Key side effects was the severity. “We often find reports of adverse reactions with natural supplements,” said our Research Editor. “Just because a product uses ingredients found in nature does not mean they are 100% safe.”

“I am reluctant to continue to take this supplement. Yes, I feel quite energetic but to the point I cannot sit still, I feel nausea, and in general not too good,” said a user.

“I ordered this kit and was very excited to try it. However, the headaches I experienced for the first 3 days were so debilitating that I couldn’t even work,” reported a customer.

Ineffectiveness– “Does it Work?”

Dieters tell what’s really going on and based on reviews, Uni Key ingredients don’t work “Unfortunately, after 8 months this product did nothing for me,” stated a customer.

“I have seen and felt no change in the way I look or the way I feel,” reported a consumer.

“I have been taking the product for almost a month. The product (Kit) simply has not worked for me,” commented a dieter.

We’ve researched countless supplements and found that something small, like an ineffective product, could hinder your long-term weight-loss success. If Uni Key doesn’t work, will dieter’s want to use it?

Is it Backed by Science?

We took a close look at the official Uni Key website and you know what we found? The company doesn’t provide scientific research linking the formulas to weight-loss. The business works with a licensed physician, but still doesn’t offer evidence of effectiveness. At DietSpotlight, finding science to back claims is critical. If there are no studies, we have a problem.

The Bottom Line – Does Unikey Work?

So, does Uni Key help dieters lose weight? Well, we like the longevity of the company and that we found some positive customer comments. But, we have reservations about it because of the lack of published scientific research. Additionally, we’re concerned that the supplement didn’t work for some and that it may cause side effects.

If you want to lose those extra pounds, we suggest going with a supplement that’s supported by published clinical research. One with no reported negative side effects to worry about.

Among the best products we’ve seen in 2016 is one called Leptigen. The supplement contains a formula consisting of a proprietary blend of four ingredients, which have been shown in published scientific research to help improve fat loss and jump start metabolism. We can’t locate any chatter about negative side effects and reviews on the web show people are noticing excellent results.

Also, the company that makes Leptigen is providing a Special Trial Offer, a great sign of confidence in the supplement.

Uni Key is a health supplement company that markets many health related products including Ann Louise Gittleman's supplements. These supplements are meant to help a person lose weight. The most popular supplement is called the Fat Flush Diet Plan. All other supplements in the line are centered around supporting users of the Fat Flush. The system relies on urging the user to fast and perform a detoxification program to lose weight and supposedly as a liver support system. The company claims the process will help to regulate hormones and improve the metabolism of blood sugar in a healthy way. The Fat Flush Diet Plan takes 2 weeks to complete and is very intensive. The 2 week period is to be followed up by a more moderate ritual until the person's desired weight goal has been achieved. After that, a lifetime maintenance program is recommended.

List Of Ingredients

Uni Key's “The Fat Flush Kit” comes with Anne Gittleman’s book called: “The Fat Flush Plan”, Dieter’s Multivitamins and Minerals, GLA-90 and Weight Loss Formula. The products can also be found individually on the company website. Uni Key offers many more products that have their own ingredients or components that come with them.

Product Features

The Fat Flush Plan, according to the author, is a lifestyle program and is not meant to be done once and never again. The first two weeks are intensive, then this is followed by a moderate program which is then followed by a lifetime maintenance program. Utilizing this system takes commitment. There is no scientific evidence to support the effectiveness or safety of the Fat Flush Plan offered by Uni Key. The health risks may outweigh any benefits that might be possible. As with most programs of this nature, it is likely weight will return as soon as the user begins to eat again. This program is supposed to help the user by regulating hormones and improving liver function. The program is purported to be helpful to acne and other skin conditions in addition to menopausal symptom relief. These statements have not been substantiated by any scientific data. The plan offers many different variations and the company offers the supplements in different kit sizes. Fat Loss Whey protein powder is a vanilla flavored powder drink that is supposed to have enough nutrients to use as a meal replacement shake.

    I bought HCL +2 Digestive Support to possibly help with stomach pain and bloating I have been dealing with for years. It was terrible. It made my stomach far worse than it ever had been. I had to quit taking it. Then I called to see if I could return the product. Sure, I could if I paid for the expensive shipping AND even then I would only get credit for another one of their products. I rated this product only 1 star but even that was too many for my situation.

    I have been using Uni Key and Ann Louise’s Fat Flush products for years. Hands down they carry some of the highest quality supplements and have literally changed my life. I lost a total of about 40lbs and that was only in a few months. Four Years later and I am healthier than ever.
