Odyssey 222: The Most Honest Can, and the Most Caffeinated

Two things about Odyssey are true at once, and most write-ups only mention one of them.
The first is that it publishes more real numbers than any other ready-to-drink can we checked. 1,500 mg of organic lion’s mane. 1,250 mg of organic cordyceps. 85 mg of L-theanine. 100 mg of panax ginseng. Printed per ingredient, no blend.
The second is that the can also holds 222 mg of caffeine, which is where the product name comes from, and which is roughly two and a half cups of coffee.
Price: $34.85 on Amazon, $35.99 direct, for a 12 pack. About $2.90 a can
Format: 12 fl oz sparkling can
Caffeine: 222 mg from green tea. An 85 mg line also exists
Adaptogens: Lion’s mane 1,500 mg, cordyceps 1,250 mg, panax ginseng 100 mg
Also in it: L-theanine 85 mg
Disclosure tier: 1, per-ingredient milligrams
Read the brand, not just the can
Odyssey used to sell itself as a mushroom elixir. It does not any more. The store now trades as Odyssey Functional Energy, the old odysseyelixir.com address redirects there, and the whole line is built around caffeine tiers, 85 mg or 222 mg, with the mushrooms as the differentiator against a normal energy drink.
That repositioning is the most useful fact about this product, and it is why any article describing Odyssey as a calm adaptogen sipper is describing a brand that no longer exists. If you buy the 222 expecting a gentle afternoon drink, you have bought an energy drink with mushrooms in it. Which is a fine thing to buy, on purpose.
The caffeine, in context
222 mg is more than a Red Bull. That is not a criticism, it is a spec. It is a criticism only if the packaging led you to expect otherwise, and adaptogen branding does tend to.
The L-theanine is undersized for the caffeine it is buffering. The pairing of L-theanine and caffeine is well trodden, and the acute studies use around 200 mg of theanine. There is 85 mg here against 222 mg of caffeine, which is a lot of caffeine and not much of the thing that is supposed to smooth it out. If jitters are your reason for leaving normal energy drinks, look at the 85 mg caffeine line instead, which carries the same 85 mg of theanine against a third of the stimulant.
What the numbers are worth
The lion’s mane is the real headline. 1,500 mg in one can is the closest anything in this set gets to the 2 g a day used in the 2026 cognition trial. No other can here will even tell you its amount.
It is the only tier 1 can. Every other ready-to-drink product on this site either gives a blend total or gives nothing.
Who should buy it
- People who already drink energy drinks and want one that publishes its functional ingredients
- Anyone who wants a genuine lion’s mane dose in something cold and fizzy
- Buyers who want a big morning hit and know exactly what 222 mg feels like
Who should buy something else
- Anyone caffeine sensitive, or drinking these after 2pm. Take the 85 mg line, or take Recess Mood, which is caffeine free
- Anyone who wants this cheap: Four Sigmatic is 57 cents a serving against $2.90
- Anyone looking for an evening or alcohol-replacement drink. This is the opposite of that

Verdict: The best-disclosed can in the category, and the one most likely to be bought for the wrong reason. If you want mushrooms, this delivers a real dose. If you want calm, the 222 mg of caffeine will beat every adaptogen in the can to the finish line.
