FAQs: Consumer Questions & Answers

In our research for this report, we found that consumers are frequently asking the following questions online in regard to Ultra Fast Keto Boost.

No. It is a rumor that started when products similar to Ultra-Fast Keto Boost were falsely advertised, that it was one of those backed by Shark Tank. Shark Tank has denied that they support this product or others like it.

Almost everyone who follows a keto diet experiences a short phase of unpleasant symptoms as their body prepares for and enters ketosis. Ultra Fast Keto Boost is said to help you reach this state faster, so in effect, it may shorten or relieve unpleasant symptoms.

Technically, yes, although if you’re eating a non-keto diet you’re not going to benefit from the desired results. If you’re not following the keto diet plan and you are interested in taking a dietary supplement to help you lose weight, there are better options for your needs.

The ingredients in Ultra Fast Keto Boost are considered to be generally safe for consumption but should be avoided by certain individuals. The packaging specifically states that women who are pregnant or nursing, children under the age of 18, and anyone with a known health condition should avoid taking this product until they speak with a physician. One of the chief complaints about this product is digestive upset. The instructions state that the capsules should be taken between meals. However, some customers have found that taking the pills right before meals helps to prevent or relieve stomach discomfort. On a topic not related to the health claims of this product, the producers of this product have several business-related complaints filed against them with the Better Business Bureau[4]

The instructions on the bottle of Ultra Fast Keto Boost advise that you take two capsules daily, between meals. Taking more than the dosage may increase the chance of side effects.

You can purchase Ultra Fast Keto Boost straight from the product’s designated website. This product is also available for purchase from other retail outlets, such as Amazon and the product’s distributor, Justified Laboratories. There were no deals found at the time of this writing, and prices range depending on where you purchase the product. The cost of the 60-count bottle is currently about $35 on Amazon and $45 from Justified Laboratories. It’s worth noting that if you’re interested in these supplements, Justified Laboratories offers additional products for enhancing results with the keto lifestyle.

The known ingredients in Ultra Fast Keto Boost are natural and thought to be generally safe. The main concern is in the proprietary blend used by this company. A company is not obligated to disclose the formula of a proprietary blend, and as a result, you don’t always know what you’re taking or what the potential side effects might be. Some side effects of Ultra Fast Keto Boost include:

  • Digestive upset
  • Intolerance of the caffeine from the green tea leaf extract
  • Jitteriness

There is also a misconception that this product was featured on Shark Tank, which it wasn’t. It led to some confusion among people ordering the product as well.

Trying to find an effective weight loss supplement can be an overwhelming experience. Weight loss supplements often claim to provide outlandish results. Weight loss products should be analyzed based on four key factors: potential to increase metabolism, potential to meet weight loss* goals, and quality of ingredients backed by clinical studies.

Keto Blast Pro
#2 Keto Blast Pro
  • Promotes Rapid Weight Loss
  • Increases Metabolic Rate
  • Increases Energy Levels
  • Powerful Fat-Burning Properties
  • Support Appetite Control


  • Contains an all-natural blend of ingredients
  • It is said to target fat on the hips, stomach, and waist


  • It may take several months to produce results
  • Free samples are not available
  • It is a new product with limited customer reviews
  • Solid clinical data is not provided

The Bottom Line

While the diet product Keto Blast Pro may appeal to consumers for several reasons, particularly those who follow the Keto diet and prefer taking supplements in this form as opposed to pills, it is a relatively new product with limited information available. The formula is completely natural and therefore unlikely to produce any harmful side effects, but there is no solid evidence to show that it actually targets areas of fat on the body or prevents the accumulation of more fat over the long term. Additionally, it appears that this supplement may take several months to produce any noticeable results and it is not clear exactly how well it works on its own, without the benefits of regular exercise and a healthy diet plan.

#3 Razalean
  • Promotes Rapid Weight Loss
  • Increases Metabolic Rate
  • Increases Energy Levels
  • Powerful Fat-Burning Properties
  • Support Appetite Control


  • It is said to have multiple benefits
  • The formula is all natural and organic


  • Razalean is expensive
  • It has received some negative customer reviews
  • There are some reports of side effects
  • Clinical study data is not available

The Bottom Line

The diet product Razalean claims to help individuals lose weight in several ways, including increasing the metabolism and burning fat more effectively, but there is little evidence to show it works as well as the manufacturer claims it does. While Razalean contains a blend of natural, organic ingredients, including Garcinia Cambogia and Raspberry Ketones, which are relatively popular and commonly used in these types of supplements, it may not be completely safe for all individuals and there have been some reports of side effects occurring. It appears that some customers have indeed experienced some positive results from using the product, but generally, independent reviews are mixed, and this brand is more expensive than many comparable products.

Dietary supplement recommendations can be found everywhere — in commercials, through social media influencers, and from your neighbors, friends, and family. With so many different opinions, it can be hard to know which supplement is right for you. While most quality supplements undoubtedly provide health benefits, each will work in its own unique way, so it's important to determine which one will help you reach your health goals. Below you will find our subjective assessment of Ultra Fast Keto Boost based on the information available to us and our estimation of its overall efficacy.
