Akemi Coffee Boost Review (2026): What's Inside, What the Research Says, and What the Brand Doesn't Prove
A flavorless 7-ingredient sachet you stir into your daily coffee. We went through the ingredient list, the brand's claims and the guarantee terms, so you know what is confirmed and what isn't before you decide.
Our Quick Take
Confirmed
- Seven named ingredients are listed on the official page.
- About 30 mg of caffeine per sachet, from green coffee bean extract (brand-stated).
- One sachet per day; 20 sachets per box.
- A 30-day return window exists, with a restocking fee in the terms.
Not confirmed
- Per-ingredient amounts: we found no Supplement Facts panel on the offer page.
- Any clinical trial of the finished product.
- The star rating, review count and expert endorsement shown on the brand's page.
Realistic expectation
Several of these ingredients have been studied on their own, with small average effects and at doses we can't match to this sachet. It is a low-effort add-on to coffee, not a replacement for diet, activity or medical advice.
What Is Akemi Coffee Boost?
Akemi Coffee Boost is a powdered dietary supplement sold in single-serve sachets. You tear one open and stir it into hot or cold coffee, tea, a smoothie or water. The brand describes it as flavorless and odorless, so it shouldn't change how your drink tastes.
The formula combines seven listed ingredients: green tea extract, green coffee bean extract, white kidney bean extract, mulberry leaf extract, L-carnitine L-tartrate, resistant dextrin and psyllium husk powder. The brand positions it for appetite, blood-sugar response and metabolism support.
Visit the Official PageHow Akemi Coffee Boost Is Meant to Work
This is the brand's explanation, with what the research on each ingredient does and doesn't show.
Carbohydrate handling
The brand points to white kidney bean and mulberry leaf extracts, which are studied for their effect on starch and sugar digestion. Human results are modest and depend on the extract and dose.
Blood-sugar response
Green coffee bean (chlorogenic acids) and mulberry leaf are the ingredients linked to a smaller after-meal glucose rise in some trials, mostly using larger amounts than a single sachet is likely to hold.
Metabolic rate
Green tea catechins combined with caffeine slightly raised 24-hour energy use in short lab studies. The catechin amount in this product isn't disclosed, and it has about 30 mg of caffeine per sachet.
Fullness
Psyllium husk and resistant dextrin are soluble fibers. Studies on fiber and fullness generally use grams per day, so the real-world effect of one sachet depends on how much is actually in it.
Energy
The roughly 30 mg of caffeine is well under what a typical cup of coffee contains. Anything beyond that is the brand's description, not a measured result for this product.
Fat metabolism
L-carnitine is the ingredient the brand ties to using fat for fuel. A meta-analysis found a small average weight difference versus control, and the effect shrank over longer use.

Compare With the Official PageWhat the Brand Claims vs. What We Could Confirm
| Brand claim | What we found |
|---|---|
| Seven plant-derived, non-GMO, third-party-tested ingredients | The ingredient list is confirmed. Sourcing, testing and the GMP-facility statement are brand-stated; we saw no certificates. |
| Blocks carbs, steadies blood sugar, burns fat around the clock | Not shown by a study of this product. Research exists on individual ingredients, with modest average effects and doses that differ from this sachet. |
| Fewer cravings by day 5, less hunger by day 10, visible changes by day 21 | A brand timeline. No trial supporting it is cited. Results vary from person to person. |
| 4.8/5 from 3,758 reviews | The review platform isn't named, so we can't verify the rating. We don't repeat it here. |
| Endorsed by a named physician | We couldn't independently verify the credentials, so we don't rely on it. |
| 30-day money-back guarantee, "no questions asked" | The terms add a minimum 15% restocking fee on returns. See the guarantee section below. |
The 7 Ingredients, One by One
Research notes refer to the ingredient on its own. Numbers in brackets point to the references at the bottom of the page.
Green Coffee Bean Extract
Brand: slows glucose absorption; source of ~30 mg caffeine.
Research: reviews of green coffee extract report a small average weight difference, but the included trials were small and of low methodological quality [3][4].
Green Tea Extract
Brand: EGCG catechins raise resting metabolic rate.
Research: short chamber studies of catechin-caffeine mixtures found higher 24-hour energy expenditure [1][2]. The catechin amount in this sachet isn't disclosed.
White Kidney Bean Extract
Brand: blocks carb-digesting enzymes.
Research: an earlier review found trial quality too weak for firm conclusions [5]; a later analysis of one standardized extract found a small average difference in weight and body fat [6].
Mulberry Leaf Extract
Brand: slows sugar absorption after meals.
Research: a 4-week trial in people with impaired fasting glucose used 5 g/day of extract and saw a smaller after-meal glucose response [7]. A sachet likely holds far less.
L-Carnitine L-Tartrate
Brand: moves fatty acids into cells to be used as fuel.
Research: a meta-analysis of 9 trials found about 1.3 kg more weight loss than control on average, and the effect decreased with longer duration [8].
Resistant Dextrin
Brand: soluble prebiotic fiber that supports fullness.
Research: studies used about 14 g/day for 4 weeks. Gas can increase at first and then settle [10].
Psyllium Husk Powder
Brand: swells with liquid to support fullness and digestion.
Research: a review of trials in overweight and obese adults looked at psyllium taken before meals [9]. It is usually taken with plenty of fluid and can cause bloating in some people.
Important: the official page lists these ingredients but, in the pages we reviewed, gives no per-ingredient amounts except the caffeine figure.
How to Use It, and What to Watch For
Per the brand, you tear open one sachet a day and stir it into coffee, tea, a smoothie or water. It's meant to dissolve in seconds with no measuring.
- One sachet per day, hot or cold drinks
- About 30 mg of caffeine on top of your drink's own caffeine
- Two of the ingredients are fibers, which can cause gas or bloating in some people
- If you're pregnant, breastfeeding, on medication or managing a health condition, ask your healthcare provider first
Who it may suit
- You already drink coffee or tea daily and want a no-prep add-on.
- You're comfortable with modest, ingredient-level evidence.
- You're fine with about 30 mg of extra caffeine.
Who may want to skip it
- You need exact per-ingredient doses before trying a supplement.
- You're sensitive to caffeine or to fiber supplements.
- You expect fast, large results. The evidence doesn't support that.
The 30-Day Guarantee: Read the Fine Print
The brand offers a refund if you return the product within 30 days.
The brand's terms of service also reserve a minimum 15% restocking fee on processed returns, so it isn't a no-cost return. We couldn't find when the 30 days start (purchase or delivery) or who pays return shipping. Confirm both with the brand before ordering.
Shipping: the brand says orders are processed in 1 to 2 business days and standard delivery usually takes 5 to 10 business days.
