Why Is This Important?
You get the best results from consistent, high doses.
With functional mushrooms, dose and consistency get results. A sprinkle does not move the needle. Real amounts, taken daily, do. The adaptogenic mushrooms in Fungki Coffee - Lion's Mane and Reishi, are the most effective with consistent use. Here are two trials with female subjects who experienced significant benefits from taking these adaptogens regularly at high doses.
1. Lion's Mane · the focus study:
Adults aged 50 to 80 took 3,000mg of Lion's Mane every day for 16 weeks. Their cognitive scores climbed week over week, then slipped back once they stopped. The benefit tracked the dose.
Fungki Coffee delivers 1,500mg of Lion's Mane per cup.

2. Reishi · the stress and mood study:
Two groups of college-aged women took 500 mg and 1,000mg of Reishi daily for 30 days and improved across stress, mood, and overall well-being, with fitness gains alongside.
Fungki Coffee delivers 1,000mg of Reishi per cup.
3. Cordyceps · the energy and stamina study
In a 12-week double-blind study, healthy adults who took Cordyceps daily raised the point at which their bodies tire, holding a higher, steadier output before fatigue set in. The effect built over the full 12 weeks, exactly the kind of consistent gain Cordyceps is known for.
Fungki delivers 1,000mg of Cordyceps per cup: the exact dose used in this trial.
Both results showed up at full, consistent doses. That is exactly why we put 3,000mg of organic fruiting body mushroom extracts in every cup: 1,500mg of Lions Mane and 1,500mg of Reishi. With Fun gki Coffee you get the lowest price per gram of adaptogenic mushrooms in the category, and the best tasting functional coffee on the market.

Rainbo’s Fungki Coffee vs. the biggest competitor on the chart
Some brands grow their mushrooms on grain, then count the grain in the dose. Per these brand's own label, the listed weight is mycelium grown on grain, not pure mushrooms. The compounds worth paying for, like hericenones and triterpenoids, are concentrated in the fruiting body, not the grain substrate.
Fungki Coffee has 100% organic fruiting body, dual-extracted mushrooms, with verified beta-glucans on every batch. The most potent coffee alternative on the market
