What You Need to Know

Firstly, WonderSlim KLB-5 Formula ingredients include blue green algae, bromelain, lecithin, kelp, and apple cider vinegar. According to the label, you’re supposed to take about six pills a day, allowing for one bottle to last about a month. The supplement supposedly boosts metabolism and helps you lose weight. One benefit is the convenient packaging.

WonderSlim KLB-5 Formula is was created in 2001 by Diet Direct. You can purchase the supplement through the official website as well as trusted retailers. We like that we found some favorable customer comments and the longevity of the company, but read on…

Lack of Results – “No Weight-Loss?”

The first negative we had with WonderSlim KLB-5 Formula was its effectiveness. “Unfortunately, many weight-loss supplements simply don’t do their job,” said our Research Editor. “Based on some reviews, it seems like this product may fall under that category.”

“This product does not aid in weight loss…Don’t waste your money,” commented a customer.

“I’m not sure how this is suppose to help weight loss,” reported a dieter.

Other customers did notice some results while using this supplement. “I love this product. It really assist in weight loss,” said a consumer.

Side Effects – “Not Good”

Another concern we saw when reading customer reviews were reports of WonderSlim KLB-5 Formula side effects. “Took then for one day and had to stop. I started to feel nauseous,” commented a customer.

I’ve been using this product for over a year. Still difficult digesting my food and flushing out the system,” said a user.

We found that, while some users experienced adverse reactions, others didn’t experience similar effects. “It doesn’t give me any kind of heart racing side effects. I’ve been taking this for about 3 months now,” said a customer.

“It is helping keep the bloat down and helping with digestion. These are the effects I like,” reported another.

Throughout our research process, we’ve found that all it takes is something deemed problematic, like adverse reactions, to limit the chances of long-term success. If WonderSlim KLB-5 Formula is associated with negative side effects, we become a bit skeptical.

The Science – “Is It There?”

WonderSlim KLB-5 Formula provides a wealth of information about the product, however, there’s no clinical research supporting the claim. Here at DietSpotlight, we like to see some science before making suggestions. If a company can’t back a supplement by offering solid science, we become concerned.

What Users Are Saying

"”The shakes are delicious, feels like you are getting a treat!”"

"”I purchased them as my first foray into the protein diet drink territory. It’s much tastier than I expect it to be. It was a tiny bit grainy, but nothing to bad. I mixed it with milk the first time, but I think it will be fine with water. With the milk it tastes like chocolate pudding that hasn’t set.”"

"”Good taste, but don’t like the ingredients.”"

The Bottom Line – Does WonderSlim KLB-5 Formula Work?

Are you heading out for a bottle of WonderSlim KLB-5 Formula? Well, we like that it contains a few natural ingredients and the longevity of the company, but we’re skeptical about this one because there’s no scientific research backing the claims. We’re also concerned based on customers talking about it not working and causing negative side effects.

If you are ready to lose weight, we suggest going with a supplement packing a formula that works and no reports of harmful side effects.

Among the best products we’ve seen this year is one called Dietspotlight Burn. The supplement contains some clinically-tested ingredients and has been shown to accelerate metabolism and ignite fat loss. Customers are talking about seeing great results and there are no mentions of adverse reactions.

Right now, the makers of Dietspotlight Burn are offering a special trial offer to all new customers, and we think you should check it out.
