Keto F1 is a dietary supplement that purports to help you enter a ketogenic state, helping increase your metabolism and burn fat. It sells and ships from third-party vendors under several manufacturer names. 

We wanted to know more about this product and looked into the formula and research to see if these claims are possible and what they might do for you.

What is Keto F1?

Eating a low carbohydrate diet, intermittent fasting, and exercise are methods that people use to reach a ketogenic state. Can Keto F1 diet capsules help, and what can a ketogenic state do for you physically and mentally?

  • Nutrients: Many people try a ketogenic diet to burn fat or improve their blood sugars. Authors of a 2021 article conclude that despite study limitations, ketogenic diets help positively with body composition and glucose to insulin homeostasis. These results were in obese or metabolically impaired patients.
  • Mental Health Clinician: There has been some research into the potential mental health benefits of a ketogenic diet. A 2021 review article looked into several studies. It notes that data demonstrated a positive response in individuals with various psychiatric disorders who maintained the diet.
  • Science Advances: A 2021 article looked at two studies (one human and one rat model) to see how a ketogenic diet (KD) performed vs. a standard American diet (SA) regarding alcohol detox. Both tests demonstrated potential benefits with managing alcohol withdrawal symptoms.

Who is Behind Keto F1?

The company behind the Maximum Strength Keto F1 Advanced Ketogenic Weight Loss supplements is unknown. The research indicates that this formula sells under several brand names with identical packaging. For example, it is offered on Amazon from Kivus and Walmart from Tygaz. Adding to consumer confusion is that these brands sell on several websites and ship by third-party distributors.

Customer Service

Keto F1 Customer Service

It is challenging to gauge Keto F1 customer service with different brands selling this product. On Amazon, customer ratings and reviews focus on the supplement and not the listed manufacturer Kivus. Walmart seller ratings are for the third-party retailer Health & Wellness Plus and not the listed manufacturer Tygaz.

The research did not find verifiable contact information for these manufacturers.


Manufacturers/Distributors and the Better Business Bureau

As you might expect with these F1 Keto pills manufactured and distributed by several companies, you will not find a Better Business Bureau (BBB) file. There are no verified F1 Keto reviews by customers or complaints resolved in the past three years.

Internet Myths

Carrie Underwood, Shark Tank, and Other Internet Myths

While searching for the right Ketogenic supplement, you have likely found claims about supplements being the product from the reality show Shark Tank or that it is the dieting secret that a particular celebrity endorses or uses. These are fabrications.

Shark Tank judges Mark Cuban and Lori Greiner are quoted by USA Today saying that the ads are false. The article points out that judges did not endorse a keto diet pill and that such a product has never appeared on their reality TV program.

In a 2020 interview in Women’s Health, Carrie Underwood said she is getting closer to vegan, with her macronutrient intake at the time consisting of 45% carbs, 30% fat, and 25% protein. Her dieting has consisted of calorie restriction and not a particular diet routine. She is not doing a ketogenic diet, with nearly half her caloric intake being carbohydrates.


Keto F1 Claims

The manufacturers, distributors, and Keto F1 reviews from customers claim it helps with natural ketosis, metabolic rate, and ketogenic fat burning.


Keto F1 Ingredients

The label lists the product quantity as 800mg, but the supplement facts on the back of the label show 1,200mg of contents. One serving size is two capsules, and there are 30 servings per container. The Keto F1 ingredients in each serving include:

  • Raspberry Ketones 500mg
  • African Mango Seed (Irvingia gabonensis) 800mg
  • Proprietary Formula 400mg
Weight Loss

Keto F1 and Weight Loss

Do any of these ingredients help with losing weight? The second most used component in the Keto Proprietary Blend is the 500mg of Raspberry Ketones. In 2013, Alternative and Complementary Therapies stated that preliminary research in cells and humans suggests it might help mitigate obesity and weight reduction.

The top ingredient by volume is the African Mango Seed (Irvingia gabonensis) at 800mg. A 2014 article from the Journal of the Korean Society of Food Science and Nutrition suggests that evidence shows this extract can reduce weight gain in leptin-deficient rodents. That might demonstrate potential human benefit.

Mediators of Inflammation discussed the results of mice tests in 2013 involving Green Tea Extract (Camellia sinensis). The journal concluded that results indicate a reduction in body weight and adipose tissues. The extract altered TNF-a in the tissues and stimulated lipolytic enzymes.

The Egyptian Journal of Hospital Medicine compared Orlistat, Chitocal, Green Tea (GT), and Apple Cider Vinegar (ACV) for weight reduction in rats. It concluded that ACV (an ingredient in the F1 blend) generated a decrease in body weight gain compared to the control group.

Does it Work?

Does Keto F1 Work? Other Benefits

One of the components in the Proprietary Formula is Kelp (Ascophyllum nodosum). The journal Molecules stated in 2021 that growing evidence from clinical trials shows that brown seaweed extracts could have a potential role as a functional food for several metabolic conditions.

Another ingredient in that blend is Grape Seed Extract (Vitis vinifera L.). Foods looked at Grape Seed Oil in 2020. It highlights that some constituents show antioxidant and anti-inflammatory activities. Nutritional and therapeutic compounds include linoleic acid, vitamin E, phytosterols, and hydrophilic phenols.

One of the Proprietary Formula ingredients is Caffeine Anhydrous. The journal Sports Medicine reviewed caffeine in 2019. It suggested that caffeine gets used by athletes and non-athletes alike. The journal also stated that caffeine has a clear and well-established enhancing effect on exercise performance.

Side Effects

Potential Keto F1 Side Effects

All supplements can cause potential side effects. Those symptoms can include allergic reactions to ingredients, drug interactions with other medications, body pains, adjustments in bodily functions, and emotional or mental changes. Also, dieting to lose weight, detox the body, or alter metabolism can create unwanted physical or mental responses.

Can I Take With...

Can I Take Keto F1 With…

The Food and Drug Administration (FDA) does not approve or regulate dietary supplements or the supplement industry, even more so with products manufactured in overseas facilities that are unverified through Current Good Manufacturing Practices (cGMP).

Consult your healthcare team (physician, dietician, specialists) before starting any supplement, especially if you have any underlying health conditions or you currently take prescription medications.


How To Take Keto F1: Directions

The label indicates that one serving consists of two capsules. There are no indications of the number of servings daily, maximum doses, or supplement timing.

Similar products often suggest taking the capsules with 8-12 ounces of water. Other brands also recommend taking their products 20-30 minutes before a meal, but it is unclear if this will produce the best Keto F1 results. We can not speculate about the safety or benefits beyond one daily dose of this product.

Pros and Cons

Pros and Cons


  • A ketogenic diet uses fat as a fuel source instead of carbohydrates
  • Positive Keto F1 reviews indicate the product helps them achieve ketosis
  • Keto F1 results could be boosted with intermittent fasting windows


  • These F1 Keto pills are made by a company with no data about manufacturing processes or quality control
  • F1 Keto reviews are mixed, but fall under 3.0 out of 5.0-star ratings
  • No Daily Value (DV) has been established for any of the Keto F1 diet pills
Bottom Line

Bottom Line on Keto F1 Results

The F1 formula of keto pills contains ingredients that might help you achieve a ketogenic state (or get there sooner). However, a lack of data from multiple manufacturers and distributors makes it hard to assess the quality of those ingredients. There are similar formulas available that come from established companies with third-party testing and cGMP standards. It is also important to note that customer feedback is less than stellar.

The keto diet is extremely difficult to follow long-term, so the majority of people losing weight using the method quickly gain it back. Instead of staying on the weight-loss yo-yo, why not try something different like Noom. With Noom users have guidance throughout the process from trained coaches and a dedicated support group. It’s also pretty cool that the Centers for Disease Control and Prevention list Noom as a healthy lifestyle option.
