SlimSet Reviews and Complaints (2026): 138 mg Caffeine, Price

SlimSet is a once-a-day capsule marketed for weight management, with a sales page aimed at women over 45. Its label is unusually transparent: five ingredients, every dose listed, including 138 mg of caffeine anhydrous per capsule. A bottle holds 30 capsules and costs $49 to $79 as a one-time payment on slimset.us, with a 60-day money-back guarantee. Below: the label, the research on each ingredient, practical caffeine guidance, the price and the refund terms.

What is in a SlimSet capsule?

Here is the full Supplement Facts panel, per one-capsule serving:

The only other ingredient is hypromellose, the plant-based material the capsule is made of. There is no sugar, no gummy base and no proprietary blend, and the site text matches the label. In a category where many products hide amounts behind a blend, that openness deserves credit.

The bottle is distributed by Slimset from a PO Box in Ogden, Utah, and says "Manufactured in the USA with globally sourced ingredients".

Every ingredient, up close

Here is every active ingredient on the label, what it actually is, and what research does and does not show.

Green coffee bean extract (Coffea robusta, seed)

130 mg (50% chlorogenic acids)

Green coffee is simply unroasted coffee, rich in chlorogenic acids; at 50% standardization, 130 mg supplies about 65 mg of them. A 2011 meta-analysis (Onakpoya) pooled a handful of small trials and found a small effect on body weight but warned the trials were low quality and at risk of bias, and the NIH Office of Dietary Supplements calls the evidence limited. Green coffee also contains some caffeine that the label does not quantify.

Raspberry ketone

130 mg

The compound behind the smell of red raspberries, usually made in a lab for supplements. ODS points out there are no published human trials of raspberry ketone on its own for weight, so there is no studied dose to compare this 130 mg against, and no human study supports targeting fat "around the midsection".

Garcinia extract (Garcinia cambogia, fruit)

130 mg (50% HCA)

A small, pumpkin-shaped tropical fruit from South Asia whose rind contains hydroxycitric acid (HCA); 130 mg at 50% HCA is about 65 mg of HCA. A 2011 meta-analysis found a small difference that the authors did not consider clinically meaningful, ODS notes little or no effect overall, and the trials generally used far more HCA than this. ODS also mentions case reports of liver injury linked to garcinia products.

Caffeine anhydrous

138 mg

Purified, dried caffeine, the ingredient you will feel most directly. Caffeine slightly raises the energy the body uses, and a 2019 meta-analysis (Tabrizi) suggested a small, dose-related effect on weight. 138 mg is in the range of a strong cup of coffee, so count it toward the FDA's roughly 400 mg a day for healthy adults.

Green tea extract (Camellia sinensis, leaf)

130 mg (98% polyphenols, 45% EGCG)

A highly concentrated leaf extract: 98% polyphenols, 75% catechins, 45% EGCG (about 58 mg) and under 3% caffeine. A Cochrane review (Jurgens, 2012) of green tea preparations found a very small weight difference that was not statistically significant, and the trials used varied doses, so 130 mg cannot be matched neatly to a result. NCCIH notes rare liver injury from concentrated green tea extracts.

How much caffeine is in SlimSet, and is it safe for you?

Each capsule lists 138 mg of caffeine anhydrous. The green tea extract can add up to about 4 mg more (it is standardized to under 3% caffeine), and the green coffee extract may contribute some caffeine that the label does not quantify. So think of one capsule as roughly 140 mg or a little more.

How to use that number:

• Count your total. The FDA cites about 400 mg a day as an amount not generally associated with negative effects in healthy adults. Add up SlimSet plus your coffee, tea, soda, energy drinks and pre-workout products. The brand itself says not to combine SlimSet with other caffeinated products.
• Skip it if you are sensitive. If caffeine makes you jittery, anxious or keeps you awake, this is probably not your product.
• Pregnant or nursing? The label and site both say to avoid it or consult a physician. Not for anyone under 18.
• Heart rhythm problems or high blood pressure? The site says SlimSet is not for people with a heart condition or high blood pressure. Caffeine can cause palpitations.
• Stimulant or other medications? Caffeine interacts with stimulant drugs and some other medicines. Ask your doctor or pharmacist.

Timing: the label says to take one capsule 20 to 30 minutes before a meal, and the site suggests about 30 minutes before the morning meal. If caffeine affects your sleep, the morning option is the more comfortable one.

How much does SlimSet cost?

Three packages, each a one-time charge; the FAQ says there are no subscriptions or auto-rebills.

2 bottles60-day supply$79 /bottle$158 · + shippingCheck availability →Best value6 bottles180-day supply$49 /bottle$294 · free shipping + 3 e-booksCheck availability →3 bottles90-day supply$69 /bottle$207 · shipping shown at checkoutCheck availability →

The 6-bottle package ships free (the support page says it "always ships free within the US") and includes three e-books: The Metabolism Reset Guide, Crave Less Live More and Energized & Active. For 2 and 3 bottles, the order page shows both "FREE USA Shipping" and "+ Shipping" on the same card and no fee is stated anywhere, which is why we list shipping as shown at checkout. Check the final total on the checkout page before paying. The order page also mentions bonuses on the smaller packs, while the sales page presents the e-books as a 6-bottle gift, so do not count on them with 2 or 3 bottles.

SlimSet refund policy: how the 60 days work

Every order from the official Slimset store is covered by a 60-day money-back guarantee, and it is a one-time payment with no subscription.

1. Stay within 60 days of your original order date.
2. Email support@healthyconsumer.us with your order number and checkout email. The support page also lists (877) 257-0825, Monday to Friday.

5. Wait 5 to 10 business days after approval for the refund on your original payment method.

If the package arrives damaged or wrong, report it within 30 days of delivery.

Who should talk to a doctor before taking SlimSet?

Beyond the caffeine points above, check with your doctor first if you:

• have liver disease or a history of liver problems: both green tea extract and garcinia have rare reports of liver injury;
• take nadolol or other beta-blockers: green tea extract may reduce nadolol levels;
• live with anxiety, hypertension or a heart rhythm disorder;
• take any prescription medication.

Stop and seek medical care if you notice yellowing of the skin or eyes, dark urine or pain in the upper right abdomen, possible signs of liver trouble. Also, midlife weight changes can be tied to thyroid, hormonal or medication causes, and they are worth discussing with your doctor.

Our verdict on SlimSet

SlimSet does something many weight-management supplements do not: it tells you exactly how much of each ingredient you are taking. The formula is simple, one capsule a day, sold with a one-time payment and a 60-day guarantee. Its ingredients have modest research behind them, and the caffeine makes it a product to choose deliberately. If you tolerate caffeine well and want a transparent daily capsule alongside your eating and activity plan, it is a reasonable option to try from the official site.

Your doubts, answered honestly

Is SlimSet a scam?

Verifiable: every ingredient amount is printed on the label with no proprietary blend, the site text matches the label, the bottle names a distributor PO box in Ogden, Utah, support is reachable at support@healthyconsumer.us and (877) 257-0825, there is no subscription according to the FAQ, and the refund steps are written down. What nobody can promise is the weight result, because the research behind these ingredients is modest.

Why does it cost $49 to $79 a bottle?

A bottle is 30 capsules, one a day: about $1.63 a day on the 6-bottle package and about $2.63 a day on the 2-bottle package, plus whatever shipping the checkout shows on the smaller packs. You are paying for five ingredients in one capsule. Caffeine tablets and single-ingredient green tea extract are usually much cheaper, so if caffeine is the part you feel, know that it is also the cheapest part to buy on its own.

Will SlimSet work for me?

None of the studies tested SlimSet itself. The ingredient research shows small effects at best: green coffee and caffeine with small weight differences in low-quality or modest trials, garcinia with a difference the authors did not call clinically meaningful, and no human trial for raspberry ketone alone. It will not target belly fat. If you already drink a lot of coffee, you are the least likely to notice anything from the caffeine.

Is it safe? Can I take it with my medication?

The 138 mg of caffeine is the main issue: count your coffee, tea, soda and energy drinks toward about 400 mg a day, and skip it if you are caffeine-sensitive, pregnant, nursing, under 18, or have a heart condition or high blood pressure. Green tea extract and garcinia have rare reports of liver injury, green tea extract may reduce nadolol levels, and caffeine interacts with stimulant drugs. Ask your doctor if you take any prescription medicine.

What if it doesn't work for me?

You have 60 days from the original order date. Email support@healthyconsumer.us with your order number, return any remaining or unopened bottles to SLIMSET, PO Box 12730, Ogden, UT 84412, and keep the digital bonuses. You pay return postage unless the product arrived damaged or wrong, shipping charges are not refunded, and the refund takes 5 to 10 business days after approval.

Why not just buy it on Amazon?

Amazon is not listed by the brand as an authorized seller, and the 60-day guarantee covers orders from the official store. We cannot vouch for listings elsewhere, and their refund terms would not be the brand's.

Do you get paid if I buy?

Yes. If you buy through our buttons we may earn a commission, at no extra cost to you. It does not change the price or what we write, which is why the caffeine warning sits near the top of this review. The buttons go to the brand's official site.
