IQBAR's instant mushroom coffee is one of the most-reviewed on Amazon. It is genuinely convenient and genuinely sugar-free. Whether it is a lion's mane product worth the name is a more careful question.

Verdict: IQJOE is the best mushroom coffee to carry and a middling one to scrutinize. The sticks are zero-sugar, individually wrapped, taste like a decent instant coffee, and pair lion's mane with magnesium L-threonate in a formula made by IQBAR, a real and established low-sugar brand. The 16-stick variety pack was $19.99 with a 4.4-star average across roughly 2,100 Amazon ratings on August 23, 2026. What it is not is a disclosure-forward lion's mane product: the front label does not itemize fruiting-body extract, and the per-stick mushroom amount is modest.
Buy it for what it is. If you want a mushroom coffee habit that survives travel, an office, or a hotel room, IQJOE is the easiest answer on Amazon. If you want a mushroom coffee whose mushroom you can verify, Four Sigmatic's ground bag says more on the label and costs less per cup. If you want lion's mane itself, neither coffee is the tool; a verified capsule is.
This review covers the formula, the flavors, sourcing disclosure, caffeine, cost per cup, and who should buy it, using the live Amazon listings and IQBAR's published product details. Prices and ratings are from August 23, 2026.

The short version
- Zero sugar, single-serve, instant: the most portable mushroom coffee format there is, from an established brand.
- Formula pairs lion's mane with magnesium L-threonate; the 16-stick variety pack was $19.99 on August 23, 2026, the 40-stick Caffe Mocha box $47.48.
- 4.4-star average across roughly 2,100 ratings on the variety listing and more than 14,000 across the IQJOE line, one of the largest review bases in mushroom coffee.
- The honest gap: the front label does not itemize fruiting-body extract, and the mushroom dose per stick is a functional add, not a supplement serving.
- Cost per cup is higher than a bag of ground coffee; you are paying for portability.
- Verdict: the convenience pick in mushroom coffee, not the potency or disclosure pick.

Our PickIQJOE Instant Mushroom Coffee Packets, Variety Pack (16 sticks)
The sampler: four flavors in one box before you commit to a 40-stick single flavor.
Lab report: Single-serve instant coffee sticks with lion's mane and magnesium L-threonate, zero sugar, made by IQBAR. Confirm the current per-stick mushroom and caffeine figures on the listing; the front label does not itemize fruiting-body sourcing.
IQJOE is what happens when a protein-bar company makes coffee: portion control first. Every stick is an individually wrapped single serving of instant coffee with lion's mane and magnesium L-threonate, zero sugar, and a short ingredient list. Tear, pour hot water, stir. The taste is a solid instant coffee, which is the right bar for the format; nobody buys sticks for a pour-over experience.
Per cup it costs about $1.25, more than a bag of ground mushroom coffee and less than a cafe. As a supplement-adjacent food it has not been evaluated by the FDA and is not intended to diagnose, treat, cure, or prevent any disease.

- Instant single-serve sticks

- Lion's mane + magnesium L-threonate
- Sugar

- Pack
- 16 sticks, four flavors

- Amazon
What we like
- Single-serve sticks go anywhere
- Zero sugar
- Four flavors to try
- Established brand with a large review base
Worth noting
- Sourcing not itemized on front label
- Modest mushroom dose per stick
- Higher cost per cup than ground
Who should buy it: Anyone who wants a zero-sugar mushroom coffee they can keep in a bag or a desk, and first-time buyers who want to find their flavor before buying a big box.
What we don't like: Sourcing is not itemized on the front label, the mushroom dose per stick is modest, and you pay more per cup than for ground coffee.
Bottom line: The variety pack is the right first purchase because flavor preference decides whether you keep the habit, and the four flavors differ more than you would expect. At $19.99 for 16 sticks it is cheap enough to be a trial and large enough to tell you whether a desk-drawer mushroom coffee is something you will actually reach for.
02 · Best for Committing
IQJOE Instant Mushroom Coffee Packets, Caffe Mocha (40 sticks)
The big box of the most popular flavor, for people who already know they like it.
Lab report: Same formula as the variety pack in a 40-stick single-flavor box. Confirm the current per-stick figures on the listing.
The 40-stick Caffe Mocha box is the same formula as the variety pack with the mocha flavor locked in. At $47.48 on August 23, 2026 it works out to about $1.19 a stick, a small saving over the sampler, and the real benefit is not running out mid-week.
As a supplement-adjacent food it has not been evaluated by the FDA and is not intended to diagnose, treat, cure, or prevent any disease.
- Format
- Instant single-serve sticks
- Actives
- Lion's mane + magnesium L-threonate
- Sugar
- Zero
- Pack
- 40 sticks, one flavor
- Where to buy
- Amazon
What we like
- Best per-stick price in the line
- The most popular flavor
- Six-plus weeks of workday cups
Worth noting
- Single flavor
- Small saving over the sampler
Who should buy it: Repeat buyers who have settled on mocha and want the best per-stick price.
What we don't like: One flavor for 40 sticks is a commitment, and the saving over the variety pack is small.
Bottom line: Once you know you like IQJOE, the 40-stick box is the sensible way to buy it. Caffe Mocha is the crowd favorite, the per-stick price drops slightly, and a box lasts most people six to eight weeks of workday cups.
Key terms
- Magnesium L-threonate
- A form of magnesium included in IQJOE's formula alongside lion's mane. Not a mushroom ingredient.
- Functional dose
- The modest mushroom amount in a coffee product; enough to be present, not an extract-grade serving.
- Fruiting-body extract
- A concentrate made from the actual mushroom rather than grain-grown mycelium. Stated by some mushroom coffees, not itemized on IQJOE's front label.
Questions, answered
Is IQJOE mushroom coffee good?
Yes, as a convenient zero-sugar instant coffee. It is made by IQBAR, an established brand, carries a 4.4-star Amazon average across thousands of ratings, and the sticks go anywhere. It is not the pick if you want a verifiable lion's mane dose or itemized fruiting-body sourcing; Four Sigmatic's ground coffee is stronger on disclosure.
How much caffeine is in IQJOE?
IQJOE is regular-caffeine instant coffee. Confirm the per-stick figure on the current Amazon listing, since brands revise formulas; it is not a decaf or low-caffeine product.
Does IQJOE have sugar?
No. Every IQJOE stick is zero sugar, which is the brand's core pitch carried over from IQBAR's protein bars. The mocha flavor tastes sweeter than the plain coffee sticks but still contains no sugar.
How much lion's mane is in IQJOE?
A functional amount per stick rather than a supplement-grade dose; check the supplement facts panel on the listing for the current milligrams. Human trials used roughly 1 gram of extract per day, which is more than a cup of any mushroom coffee carries.
Is IQJOE worth the price?
At about $1.25 a stick it costs more per cup than ground mushroom coffee and far less than a cafe. It is worth it if portability and zero sugar are what you are paying for; it is not the value pick if every cup is brewed at home.
Is IQJOE safe to drink daily?
For most people, yes, within normal caffeine limits; lion's mane is generally well tolerated in the published research. Skip it if allergic to mushrooms and check with a clinician if pregnant, breastfeeding, on medication, or managing a condition. These statements have not been evaluated by the FDA and the product is not intended to diagnose, treat, cure, or prevent any disease.
