Keto F1 is a dietary supplement marketed to help you enter ketosis, boosting metabolism and fat burning. It’s sold and shipped through third-party vendors under several different manufacturer names.

We looked into the formula and supporting research to see whether the claims genuinely hold up and what it might actually do for you.
What Is Keto F1?
Low-carb dieting, intermittent fasting, and exercise are common ways to reach ketosis. Can Keto F1’s capsules genuinely help, and what does ketosis actually do for the body and mind?
- Nutrients: despite study limitations, ketogenic diets genuinely support body composition and glucose-insulin homeostasis in obese or metabolically impaired patients, per a 2021 article.
- Mental Health Clinician: a 2021 review found genuine positive responses to ketogenic dieting among individuals with various psychiatric conditions.
- Science Advances: 2021 research (human and rat models) found ketogenic diets genuinely showed potential benefits managing alcohol withdrawal symptoms versus a standard American diet.
Who Is Behind Keto F1?
The company behind “Maximum Strength Keto F1 Advanced Ketogenic Weight Loss” is genuinely unclear — the formula sells under multiple brand names with identical packaging (Kivus on Amazon, Tygaz on Walmart), each shipped by third-party distributors, adding real confusion for shoppers.
Keto F1 Customer Service
Gauging customer service is genuinely difficult given the multi-brand structure. Amazon reviews focus on the supplement, not manufacturer Kivus specifically; Walmart ratings reflect third-party seller Health & Wellness Plus, not manufacturer Tygaz. No verifiable contact information exists for either manufacturer.
Manufacturers/Distributors and the Better Business Bureau
Given the multi-company structure, no BBB file exists, and no verified reviews or resolved complaints appear over the past three years.
Carrie Underwood, Shark Tank, and Other Internet Myths
Marketing around keto supplements frequently invokes fake celebrity endorsements or reality-TV appearances — these are fabrications. Per USA Today, Shark Tank judges Mark Cuban and Lori Greiner confirmed no keto diet pill ever appeared on the show, and no endorsement occurred. Separately, in a 2020 Women’s Health interview, Carrie Underwood described a diet of 45% carbs, 30% fat, 25% protein — nowhere close to a ketogenic approach.
Keto F1 Claims
Manufacturers, distributors, and customer reviews claim the product supports natural ketosis, metabolic rate, and ketogenic fat burning.
Keto F1 Ingredients
Labeling shows some inconsistency — 800mg on the front, 1,200mg on the supplement facts panel. One serving equals two capsules, 30 servings per container:
- Raspberry Ketones 500mg
- African Mango Seed (Irvingia gabonensis) 800mg
- Proprietary Formula 400mg
Keto F1 and Weight Loss
Raspberry Ketones show genuine preliminary promise for obesity and weight reduction in cell and human research, per a 2013 Alternative and Complementary Therapies article.
African Mango Seed, the top ingredient by volume, genuinely reduced weight gain in leptin-deficient rodents, per a 2014 article in the Journal of the Korean Society of Food Science and Nutrition, suggesting possible human benefit.
Green Tea Extract genuinely reduced body weight and adipose tissue in 2013 mouse research covered by Mediators of Inflammation, altering TNF-a and stimulating lipolytic enzymes.
Apple Cider Vinegar, part of the F1 blend, genuinely reduced body weight gain in rats versus control, per the Egyptian Journal of Hospital Medicine.
Does Keto F1 Work? Other Benefits
The Proprietary Formula’s Kelp (Ascophyllum nodosum) genuinely shows growing clinical evidence as a functional food for metabolic conditions, per a 2021 Molecules review.
Grape Seed Extract genuinely offers antioxidant and anti-inflammatory activity via linoleic acid, vitamin E, phytosterols, and hydrophilic phenols, per a 2020 Foods review.
Caffeine Anhydrous genuinely delivers a well-established exercise performance boost, per a 2019 Sports Medicine review.
Potential Keto F1 Side Effects
All supplements carry potential side effects — allergic reactions, drug interactions, body pain, digestive changes, and mood shifts are all possible, alongside typical dieting-related discomfort.
Can I Take Keto F1 With…
The FDA doesn’t approve or regulate dietary supplements, particularly overseas-manufactured products lacking verified cGMP compliance. Consult your healthcare team before starting, especially with underlying conditions or prescription medications.
How to Take Keto F1
One serving equals two capsules — no clear guidance on daily servings, maximum dose, or timing. Similar products typically recommend 8-12oz of water and dosing 20-30 minutes before a meal, though we can’t confirm this produces optimal Keto F1 results specifically.
Cost and Where to Buy
Sold exclusively through third-party distribution, not in stores:
- Amazon (Kivus brand): $29.95 for 60 capsules
- Walmart (Tygaz brand): $24.95 for 60 capsules
Can You Cancel My Supplement Subscription?
No recurring subscription option was found for this product. We can’t cancel retailer subscriptions in general — contact the outlet you subscribed through.
Pros and Cons
Pros
- Ketogenic dieting genuinely uses fat as fuel over carbs
- Positive reviews suggest it genuinely helps some reach ketosis
- Results could be boosted by pairing with intermittent fasting
Cons
- No transparency around manufacturing or quality control
- Mixed reviews, generally under 3.0 out of 5.0 stars
- No established Daily Value for the ingredients
Bottom Line on Keto F1 Results
Keto F1’s ingredients might genuinely help you reach ketosis sooner, but the lack of transparency across multiple manufacturers makes ingredient quality genuinely hard to verify. Similar formulas exist from more established, third-party-tested companies, and customer feedback here runs less than stellar.
The keto diet is genuinely hard to sustain long-term, with most people regaining lost weight. A comprehensive, clinically-backed program with trained coaches and dedicated support offers a genuinely different path — recognized by the CDC as a healthy lifestyle option.
