LeeFar is a women's supplement brand that sells drink mixes and gummies, and it became one of the ten best-selling supplement brands on TikTok Shop this year. The company markets its Cutting Mix as a "Dual-Action Craving & Metabolism Support" drink mix.
But are LeeFar's active ingredients effectively dosed? Does the Cutting Mix support the GLP-1 pathway, as its product title claims? Is LeeFar better or worse than other weight loss supplements like Olly Metabolism Gummies? And why do we take issue with some of the brand's website claims?
In this article we'll answer all of these questions and more, as we analyze the ingredients in LeeFar Cutting Mix and LeeFar Women's Probiotic + Slippery Elm Gummies to give our take on whether or not they're effectively formulated.
We'll also discuss the risk of side effects, share our concerns with the brand's marketing claims and its many websites, and compare LeeFar to other popular metabolism supplements to pick our winners (and losers).
Key takeaways:
- Publishes every active ingredient dose
- Active ingredients dosed below research levels
- We do not currently recommend LeeFar
Cutting Mix Ingredient Analysis
The ingredients in LeeFar Cutting Mix are shown below:
image source: https://leefar.shop/
Berberine HCl is the lead active ingredient at 300 milligrams (mg) per stick.
Berberine is clinically shown to cause modest weight loss, but the trials behind that finding used 1,500 mg per day, or five times the dose in this drink mix, as we documented in our berberine for weight loss article.
5-HTP is included at 100 mg, and a 2023 clinical trial using that same 100 mg dose for eight weeks found no change in food intake.
A 1992 clinical trial that did report reduced appetite used 900 mg of 5-HTP per day, or nine times the dose here.
Chromium picolinate is included at 200 micrograms (mcg).
A meta-analysis published in the International Journal of Obesity found chromium's effect on body weight to be statistically significant but small, and the trials testing it for cravings used five times this dose.
Yerba mate extract is included at 300 mg as a caffeine source, but the label doesn't list how much caffeine a stick contains.
We consider undisclosed caffeine content a transparency problem in a product meant to be taken daily.
Allulose is a refined sugar we recommend avoiding, and added sugar intake is associated with increased cardiovascular disease risk in a population study.
Citric acid is clinically shown to cause whole-body inflammation in some individuals.
Natural flavors is a broad descriptor that may include synthetic solvents and preservatives, according to a medical review.
We do not consider LeeFar Cutting Mix likely to be effective for cravings or metabolism, because we cannot identify a single active ingredient in it that reaches the dose used in research.
We do not currently recommend this product, both for that reason and because of the three inactive ingredients highlighted above.
LeeFar vs. Popular Weight Loss Brands
Here's how LeeFar Cutting Mix compares to other popular metabolism supplements in terms of formulation quality, in our opinion:
Leanbean
This is a weight loss supplement marketed specifically to women.
We consider its active ingredients underdosed too, and supplement-driven weight loss is modest across this whole category according to a 2023 meta-analysis of 111 randomized trials.
The difference is the inactive ingredients: Leanbean contains none that we consider unhealthy, while LeeFar Cutting Mix contains allulose, natural flavors and citric acid.
Leanbean is the winner from a health perspective.
Winner: Leanbean
Olly Metabolism Gummies
This is a mass-market metabolism gummy sold in most US pharmacies.
As we documented in our Olly Metabolism Gummies review article, its chromium is included at a clinically effective dose, unlike the 200 mcg in LeeFar Cutting Mix.
Neither product has a clean inactive ingredient profile, because both contain citric acid and natural flavors, and Olly adds three grams of refined sugar.
Olly Metabolism Gummies is the winner from a potential efficacy perspective.
Winner: Olly Metabolism Gummies
Green Tea Fat Burner
This is a stimulant-based fat burner.
It contains green tea extract at a level we've flagged for liver toxicity concerns, plus titanium dioxide, which is banned as a food additive in the EU.
LeeFar Cutting Mix contains no ingredient that raises comparable safety concerns.
LeeFar is the winner from a health perspective.
Winner: LeeFar
Questionable Health Claims
The official LeeFar website makes several claims we disagree with from a scientific perspective.
The Cutting Mix product title claims the drink mix "Supports GLP-1 Pathway, Blood Sugar & Gut Health," as shown below:
image source: https://leefar.shop/
We cannot identify any clinical research showing that this formulation affects GLP-1 levels or the GLP-1 pathway.
A product image goes further, calling the drink mix "Nature's zempic [sic]," as shown below:
image source: https://leefar.shop/
We consider comparing a supplement to a prescription drug like Ozempic misleading, because we cannot identify any evidence that this formulation produces comparable effects.
Another product image labels the formula "Science-Backed Ingredients" and lists 200 mg of 5-HTP and 100 mg of magnesium, as shown below:
image source: https://leefar.shop/
The brand's own Supplement Facts panel lists 100 mg of 5-HTP and 200 mg of magnesium citrate, so this graphic doubles the 5-HTP dose, and its 600 mg "Cutting Blend" figure doesn't match the roughly 400 mg blend on the label either.
As we covered in the Cutting Mix Ingredient Analysis section, we cannot identify an active ingredient in this formula dosed at research levels.
A comparison graphic claims the Cutting Mix is "Herbal-based, no side effects," as shown below:
image source: https://leefar.shop/
We disagree with any supplement claiming to have no side effects, and this one contains 5-HTP, whose safety concerns we cover below in the Side Effects section.
The official probiotic page credits the gummies' results to "L. gasseri CECT 30648 and B. coagulans SNZ 1969," along with inulin and zinc, as shown below:
image source: https://leefar.shop/
None of those ingredients appear on the product's Supplement Facts panel, which lists four different Lactobacillus species, slippery elm and XOS.
We consider it misleading to market a probiotic with clinically studied strains that the product doesn't appear to contain.
Our Healthy Body Weight Picks
Ceylon cinnamon was shown to support healthy body weight in a 2022 meta-analysis. The study authors concluded that effects were greater at doses at or over 3 grams daily.
Illuminate Labs Ceylon Cinnamon Extract is our standardized Ceylon cinnamon supplement which is third-party tested to ensure purity and potency.
Dietary fiber was shown in a medical review published in The Journal of Nutrition to help reduce body weight when combined with moderate caloric restriction (750 calories per day below baseline).
MBG Organic Fiber Potency+ is our top fiber pick because it's certified organic, provides 7 g of fiber per serving and costs under $1.85 per serving at the time of updating this article.
Both of the products mentioned in this section are free of ingredients that we consider to be unhealthy.
These statements have not been evaluated by the FDA. These products are not intended to diagnose, treat, cure, or prevent any disease.
Women's Probiotic Ingredient Analysis
The ingredients in LeeFar Women's Probiotic + Slippery Elm Gummies are shown below:
image source: https://leefar.shop/
LeeFar Probiotic Blend is listed at 60 mg across four Lactobacillus species, with no CFU count and no strain identifiers on the label.
Probiotics are dosed in colony forming units (CFU), not milligrams, and the regimens shown to shift vaginal flora in a 2025 medical review are defined by a specific strain at a specific CFU dose.
Without a CFU count or strain identifiers, a shopper cannot compare this gummy to any published trial, which is the first thing we look for in this category, as we covered in our best probiotics for women over 50 article.
The official product page also credits two strains that don't appear on this label, which we cover in the Questionable Health Claims section.
Slippery elm is the highest-dosed active at 400 mg and we cannot identify clinical research showing that oral slippery elm improves intimate moisture, freshness or vaginal pH.
Citric acid and natural flavors are included; both of which we flagged in the Cutting Mix Ingredient Analysis section.
We do not consider LeeFar Women's Probiotic likely to be effective for the intimate health benefits it's marketed for, because the probiotic dose can't be evaluated and we can't identify research supporting its highest-dosed ingredient for this use.
We do not currently recommend this product due to the missing CFU and strain disclosures.
Does LeeFar Cause Side Effects?
Neither LeeFar product appears to have been studied in clinical trials, which makes it challenging to determine whether or not they cause side effects.
However, we can make an educated guess based on the stated ingredients.
5-HTP is a serotonin precursor, and serotonin syndrome is one of the main safety concerns with its use, according to a medical review published in the Pharmacology & Therapeutics journal.
The official Cutting Mix product page doesn't appear to mention this risk, at the time of publishing this article.
The label also doesn't list the caffeine content of the yerba mate, which makes total daily caffeine intake difficult to track.
The brand's claim that the Cutting Mix has "no side effects" is covered in the Questionable Health Claims section.
We do not consider either LeeFar product likely to cause serious side effects in healthy adults, though we'd like to see the brand disclose the safety concerns that come with 5-HTP.
Challenging to Find Official Website
LeeFar sells through an unusual number of websites for a brand this size.
We identified six domains selling LeeFar products at the time of publishing this article: leefar.shop, leefarus.com, theleefar.com, myleefar.online, try-leefar.com and leefar.website.
We consider leefar.shop to be the official website, because it's the site linked from the brand's main Instagram account, @leefar_official, which has more than 42,000 followers, and it leads search results for the brand.
A second Instagram account, @tryleefar_co, links to try-leefar.com instead, and leefar.website returns a "402 Payment Required" error, which usually means the store has been suspended.
The formulas listed on leefarus.com match the official site's labels. LeeFar products are also sold through multiple TikTok Shop storefronts, Amazon and eBay.
A UK company called LeeFar Nutrition UK Ltd was incorporated in May 2025 and is currently subject to a proposal to strike off with an overdue confirmation statement.
We cannot confirm whether that UK entity operates the brand's US websites, and no founder is named on the official site.
We prefer brands that sell from one clearly identified website run by a clearly identified company.
