TrimFit is a weight loss supplement sold by a brand called Yū. The company claims that their supplement is “that energy giver, fat burner, excess calorie avoider, and mood enhancer that you need it [their typo, not ours] your life right now.”

But does TrimFit contain research-backed ingredients for weight loss, or are these just marketing claims? Does the supplement contain any questionable additive ingredients? How do real users rate and describe its effects? And does TrimFit cause side effects?

In this article we’ll answer all of these questions and more, as we analyze the ingredients in TrimFit based on medical studies to give our take on whether or not the supplement is likely to be effective for weight loss.

We’ll also feature unsponsored customer reviews and discuss side effects.

Ingredient Analysis

TrimFit Supplement Facts label

The active ingredients in TrimFit are shown above.

Dietary fiber intake predicts weight loss according to a medical review published in The Journal of Nutrition.

While we can’t find any evidence that 2 grams (g) of fiber per serving (the amount in TrimFit) causes weight loss, we have no issues with this ingredient and consider it to be a healthy, albeit small, dose.

Vitamin C is the only vitamin in this formulation, and we can’t find any clinical evidence that it’s effective for weight loss, nor does the brand cite any on the product page.

The remaining active ingredients are included in a proprietary (prop) blend with a total dose of 513 milligrams (mg), or 85.5 mg per ingredient on average.

Purple tea is the first active ingredient in the prop blend, and the brand fails to identify the botanical name which is a red flag in our opinion.

All plant compounds have botanical names that are typically listed on the Supplement Facts label. Green tea, for example, comes from the plant Camellia sinensis.

Because TrimFit fails to specify the botanical name for their purple tea, we can’t investigate medical studies to see if it’s effective or not for weight loss.

Caffeine is clinically shown to be associated with weight loss, but the linked meta-study included 13 clinical trials on caffeine and weight loss and only one used a dose lower than 100 mg.

The 85.5 mg average ingredient dose in this prop blend equates to a lower caffeine dose than one standard cup of coffee.

Caralluma fimbriata is typically used as an appetite suppressant, however as we documented in our HUM Nutrition reviews article on another brand using this ingredient, it was shown to be ineffective as an appetite suppressant in a meta-study that analyzed data from seven clinical trials.

Taurine is an amino acid that was shown to have an anti-obesity effect in a 2020 meta-study, however the lowest taurine dose used in any of the analyzed trials was 500 mg per day, which is more than 500% of the average ingredient dose in TrimFit’s blend.

L-theanine is typically used as a natural relaxation aid to counter the effects of caffeine, rather than for weight loss.

Overall, we are unconvinced that TrimFit will cause weight loss given our concerns about active ingredient dosages documented above.

This supplement also contains some inactive ingredients that we consider to be questionable from a health perspective, as shown in the full ingredient list below:

TrimFit ingredient list

Natural flavors is a broad descriptor, and without knowing the specific flavoring compounds used, we cannot assess their safety.

Citric acid is typically derived from fungus, and caused whole-body inflammatory reactions in some individuals according to a medical review published in the Toxicology Reports journal.

Sucralose is an artificial sweetener that was shown in one clinical trial to cause insulin dysregulation, as we documented in our OxyShred reviews article.

Overall, we do not recommend TrimFit due to our concerns about its potential efficacy, and due to the inactive ingredients highlighted above.

But how do real users rate and describe the effects of this supplement? We’ll feature some unsponsored customer reviews in the next section of this article.

Does TrimFit Cause Side Effects?

TrimFit doesn't appear to have been studied in any clinical trials, which makes it more challenging to assess the potential for side effects.

However, we can make an educated guess based on the supplement's active ingredients.

Caffeine can cause jitters and anxiety in some individuals, but we consider this risk to be quite low at such a low dose in this supplement.

As referenced in the ingredient analysis section, citric acid can cause inflammatory reactions in some individuals, but this response seems highly uncommon.

Part of our concern about TrimFit failing to list the botanical name for purple tea on their Supplement Facts label is that without this critical information, we cannot analyze studies on this ingredient to share our thoughts on its safety profile.

Even with all of these considerations, we consider TrimFit unlikely to cause side effects in the average consumer. There are no active or inactive ingredients that stand out to us as likely to cause harm.

There is no mention of side effects on the product page at the time of publishing this article.

Can Tea Actually Cause Weight Loss?

A YouTube creator named Madi Wilson claims to have lost over 100 pounds using detox teas, in a video with over 30,000 views:

Our Clean Weight Loss Picks

There are food-based nutrients which have been shown in medical studies to be effective for weight loss.

Dietary fiber was shown in a medical review published in The Journal of Nutrition to cause 16 pounds of weight loss in 6 months 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.

MCT oil was shown in a meta-study to cause more than one pound of weight loss over 10 weeks. This equates to potential annualized weight loss of 6 pounds per year with less than one tablespoon's worth of MCT oil per day.

Bulletproof MCT Oil is our top MCT oil product, because the only ingredient is MCT oil derived from coconuts. and it currently costs only $15.50 for over a month's worth of product.

Ginger intake "significantly decreased body weight" according to a 2019 meta-study on ginger and weight loss that analyzed data from 14 clinical trials.

Pique La Ginger is our top ginger product, because it's an organic tea in convenient crystallized form, and all that's needed is to pour the powder into a glass and add hot water.

All three of the products mentioned in this section are entirely free of additive ingredients that we consider to be unhealthy or unsafe.

Conclusion

TrimFit is an underwhelming weight loss supplement in our opinion.

While this supplement does contain some active ingredients with research backing for weight loss, most of the active ingredients are included at an average ingredient dose that's lower than the dose used in clinical trials that we can source.

Further, the brand fails to publish the botanical name for their purple tea on the Supplement Facts label, which prevents consumers and researchers from investigating the safety and efficacy of this ingredient.

We do not consider TrimFit likely to cause side effects, nor does the brand mention any risk of side effects on their product page.

At the time of publishing this article, the brand's website appears to be the only place to purchase TrimFit.
