Look at the ingredient list on almost any "focus" supplement and you'll find the same two names near the top: lion's mane and ginseng. It's not a coincidence, but it's also not what the marketing usually implies. This guide explains what each ingredient was studied for, why they end up together, how to tell the ginsengs apart on a label — and the one thing no study has tested.
TL;DR
- Lion's mane and Panax ginseng were studied separately: 1,800 mg of lion's mane in the cited single-dose study and 200 mg of standardized Panax ginseng extract in the cited arithmetic study.
- No published trial has tested lion's mane and Panax ginseng taken together, so a combination claim should not be treated as a study result.
- Focus lists 2,000 mg of lion's mane and 250 mg of Panax ginseng per two-gummy serving, with no proprietary blend and 0 mg caffeine.
Two ingredients, two different jobs
Lion's mane is a mushroom. Panax ginseng is a root. They come from different kingdoms, have been studied by different research groups, and were measured on different tasks. The reason they get paired is that they cover different parts of the same problem — the afternoon where you're present but not sharp.
- Lion's mane has been studied for how quickly people process conflicting information (a task called the Stroop test).
- Panax ginseng has been studied for how well people hold up during sustained, tiring mental work — and how tired they say they feel afterward.
One is about speed and attention. The other is about stamina. That's a sensible pair to put in the same jar, as long as the jar tells you how much of each is inside.
What the lion's mane study actually used
A randomized, double-blind, placebo-controlled trial in healthy adults gave a single 1.8 g (1,800 mg) dose of lion's mane and measured performance on the Stroop task 60 minutes later. The lion's mane group completed the task faster than the placebo group.1
The number to keep in mind is 1,800 mg. Most gummies that list lion's mane inside a "proprietary blend" contain a fraction of that — often the entire blend is smaller. If you haven't already, read how to find the real lion's mane number on any label.
What the ginseng study actually used
A double-blind, placebo-controlled trial gave adults 200 mg of a standardized Panax ginseng extract (G115) and then had them work through a demanding, repetitive mental arithmetic task. The ginseng group performed better on the arithmetic and reported less mental fatigue afterward than the placebo group.2
The number here is 200 mg — and the word "standardized" matters, which brings us to the label.
These studies examined individual ingredients at the amounts shown. They were not conducted on CappyRoots Focus Mushroom Gummies. Individual results vary.
"Ginseng" on a label can mean three different plants
This is where most people get lost, and where a lot of formulas quietly cut corners.
- Panax ginseng (Asian or Korean ginseng) — the one used in the study above. Look for the word Panax.
- American ginseng (Panax quinquefolius) — a related but different plant, with a different research history. Not interchangeable with the above.
- "Siberian ginseng" (eleuthero) — not a ginseng at all. It's a different plant that borrowed the name. If a label says "Siberian ginseng," it contains no Panax ginseng.
Two more things to check:
- Is it a standardized extract? Ginseng's active compounds are called ginsenosides, and a standardized extract states a consistent percentage of them. A label that just says "ginseng root powder" is telling you the plant, not the potency.
- Is the amount listed on its own? Same rule as lion's mane. Ginseng hidden inside a blend total is an unknown amount of an unknown potency.

The one thing nobody has tested (including us)
Here's the honest part. There is no published trial of lion's mane and Panax ginseng taken together. Each ingredient has its own study, at its own amount, measured on its own task. Nobody has shown that the pair does more than either one alone — and we're not going to tell you otherwise.
What a well-built formula can promise is simpler: each ingredient at an amount that lines up with what was actually studied, printed on the label, with nothing hidden in a blend. That's a claim about the label, not about the outcome, and it's one you can verify yourself in ten seconds.
How Focus handles both
CappyRoots Focus contains both ingredients, each disclosed on its own line. Per two-gummy serving:
| Lion's Mane | 2,000 mg |
| Cordyceps | 500 mg |
| Panax Ginseng | 250 mg |
| Caffeine | 0 mg |
Lion's mane at 2,000 mg per serving sits above the 1,800 mg used in the single-dose study. Panax ginseng at 250 mg sits above the 200 mg used in the arithmetic study. No proprietary blend, no caffeine, and no cannabinoids of any kind.
Focus is formulated to support focus and mental clarity.*

Can you take lion's mane and ginseng together?
They appear together in many commercial formulas. No published study has tested the combination itself, so any claim about the pair doing more than each alone is not supported by research. Follow the serving directions on the product you choose and talk to your healthcare provider if you take medication, have a medical condition, or are pregnant or nursing.
What's the difference between Panax ginseng and American ginseng?
They are two different species in the same genus. The mental-arithmetic study above used Panax ginseng (a standardized extract called G115), not American ginseng. Check the label for the word Panax and, if possible, a standardized ginsenoside percentage.
Is Siberian ginseng the same as ginseng?
No. "Siberian ginseng" is eleuthero, an unrelated plant. A product listing it contains no Panax ginseng.
How much lion's mane and ginseng were used in the studies?
1,800 mg of lion's mane in a single dose,1 and 200 mg of standardized Panax ginseng extract.2 Compare those figures with the per-serving amounts on any label you're considering.
Does CappyRoots Focus contain caffeine?
No. Focus is caffeine-free.
