Ultra KLB6 Review - 6 Things You Need to Know


Give me two minutes of your time and I’ll tell you whether Ultra KLB6 actually works. After looking through hundreds of comments and reviews from actual users, we decided to dig a little deeper. We looked at the ingredients, research, customer service, and side effects. Then, we condensed and refined everything

What is Ultra KLB6?

Firstly, Ultra KLB6 is a supplement that claims to be able to increase energy, boost metabolism, and aid in nutrition. The ingredients include Kelp, Soy Lecithin, Vitamin B6, and Cider Vinegar.

Ultra KLB6 is made by Holland & Barrett. The company has been operating for more than 145 years. You can buy directly from the official website. We like the longevity, and the all natural ingredients, but read on…

Not Sold in the United States – “A Problem?”

The first issue we came across was the fact that Holland & Barrett is not a company located in the United States. Ultra KLB6 can be shipped to some European countries, but it is not available for people in the US. There’s no mention of whether or not this is going to change in the near future.

No Potential for Weight-Loss With Ultra KLB6 – “Are We Serious?”

The star rating on the official website is a 1.8 out of 5. One review after the other talks about how it doesn’t work.

”This product is [ineffectiveness]. I am so disappointed,” said one user.

Another claimed, “Does not work whatsoever.”

Though, we did find a couple customers who were satisfied with the purchase.

As one put it, “I have re-ordered these again and I will continue to do so in the future.”

Our years of experience reviewing diet products has taught us that if there’s an issue, even a small one like a poor start rating, that is enough to turn the customer off to the company. If the official website for Ultra KLB6 lists a rating of less than 2 – that’s not a positive.

The Science – “Not Solid”

There aren’t any fat burners in this formula. Vitamin B6 can help with energy production, but you can find it in any multi-vitamin, and you can get it in supplement form on its own. Apple cider vinegar hasn’t been proven to help weight-loss. Here at DietSpotlight, we want to see the science that supports a product, and when we can’t, red flags go up.

What Users Are Saying

"”I think it works well. I use it as a supplement with another supplement. I am down 45 pounds. Hasn’t been instantaneous, but I didn’t gain it overnight. I would recommend it.”"

"”They’re vitamins. They work great for arthritis, unless you are sensitive to any ingredients.”"

"”Made me very nauseous. I had to stop taking because of the extreme nauseous.”"

The Bottom Line – Does Ultra KLB6 Work?

Should I race out for a bottle of Ultra KLB6? With the issues of effectiveness and low start rating, we are cautious about recommending this product. It’s just as easy to take a B6 supplement.

If you want to shed those extra pounds, why not try using a supplement that contains clinically tested ingredients, backed by a website with research and plenty of positive customer reviews?

Among the best products we’ve seen this year is Dietspotlight Burn. It’s made with four key ingredients that have all been clinically tested and shown safe and effective for helping boost metabolism and fight hunger. Our research into online customer feedback showed no mentions of harsh side effects or negative comments.

Right now, you can get a Special Trial Offer from the manufacturer, which is a good sign.

List Of Ingredients

According to the bottle label, Ultra KLB6 includes Kelp, Soy Lecithin, Vitamin B6, and Cider Vinegar.

Soy Lecithin is thought to help increase good cholesterol. Vitamin B6 is a common ingredient in weight loss ingredients because people think it works with the enzymes to improve the metabolic rate in the body. It is also thought to aid in metabolizing amino acids, glucose, lipids, and others. Apple Cider Vinegar is commonly used as an appetite suppressant. The vinegar might be helpful in treating obesity and diabetes through lower glucose levels and lower cholesterol.
