What we liked
  • $18.99 for a 10 oz bag of real medium-roast arabica — under $0.80 a cup on our estimate, the cheapest ground option here
  • Bulletproof's coffee is tested for mold toxins, and the ashwagandha is the branded KSM-66 root extract
  • A major, widely stocked brand entering the category, so it will be easy to find at retail
What held it back
  • No milligram amounts for lion's mane, reishi or ashwagandha, and no statement of fruiting body versus mycelium
  • Bulletproof does not publish servings per bag or caffeine per cup; our 24 servings and 95 mg are estimates for a 10 oz ground bag, not brand figures
  • Not organic
Who should skip it
  • You want any disclosed mushroom dose — this label has none
  • You want an instant or pod format

Why it's on our radar

Bulletproof more or less invented functional coffee with butter and MCT a decade ago, and in May 2026 it finally entered mushroom coffee with The Mood Booster. The press line was about taste — coffee-forward, none of the earthiness — and the price is aggressive. A brand this widely stocked will put mushroom coffee in front of a lot of people who have never tried it.

Taste

We have not completed a two-week test, so this rests on the ingredient list and early reviewer consensus. It is a medium-roast arabica ground with a small functional addition, and early reviews on Bulletproof's own site describe it as smooth and indistinguishable from the brand's regular coffee. That is the point of the product, and with no disclosed mushroom load it is almost certainly a light one.

Price and value

$18.99 for 10 oz is cheap for the category. Bulletproof does not state servings per bag; at a typical 12 g per cup that is about 24 cups, or $0.79 each. We have rated value on that estimate and flagged it, because a brand figure would be better than ours.

Transparency

Almost nothing. Three functional ingredients are named — lion's mane, reishi, KSM-66 ashwagandha — with no milligrams, no part used, no beta-glucan, no servings and no caffeine figure. Bulletproof's mould-toxin testing of the coffee itself is a genuine plus and the only reason lab testing does not score a one. For a brand with the resources to print a supplement facts panel, this is a thin label.

Verdict

A good-value ground coffee with a mushroom sprinkle of unknown size. Buy it if you want Bulletproof coffee anyway; do not buy it for the mushrooms until the label says how much is in it.

Frequently asked questions

How much caffeine is in Bulletproof The Mood Booster?

Bulletproof has not published a per-cup caffeine figure for The Mood Booster. It is a standard medium-roast arabica ground coffee rather than a diluted instant, so a normal 8 oz brew should land near a regular cup, roughly 90–100 mg. We list 95 mg as an estimate, not a label value.

How much lion's mane is in Bulletproof mushroom coffee?

Bulletproof does not say. The Mood Booster lists lion's mane, reishi and KSM-66 ashwagandha as functional ingredients but gives no milligram amount for any of them and does not state whether the mushrooms are fruiting body or mycelium. Until the label changes, treat the mushroom content as undisclosed.

How much does Bulletproof The Mood Booster cost per cup?

The 10 oz bag is $18.99 on Bulletproof's site and Amazon. Bulletproof does not state servings per bag; at a typical 12 g per cup a 10 oz bag brews about 24 cups, which is roughly $0.79 per cup. That would make it the cheapest ground mushroom coffee we track, with the caveat that the serving count is our estimate.

When did Bulletproof launch mushroom coffee?

The Mood Booster launched in May 2026 as Bulletproof's first entry into the mushroom coffee category, which the company described as a billion-dollar market. It is a medium-roast ground coffee with lion's mane, reishi and KSM-66 ashwagandha, sold in 10 oz bags on bulletproof.com and Amazon, and positioned around mood and everyday stress rather than focus.
