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 adaptogens in Fungki - Lion's Mane, Reishi, and Cordyceps, are the most effective with consistent use. Here are two trials with female subjects who experienced significant benefits from taking these mushrooms regularly at high doses.

1. Reishi · the stress and mood study

Two groups of women took 500mg and 1,000mg of Reishi daily for 30 days. The 1,000mg group improved across stress, mood, and overall well-being, with gains in fitness markers like oxygen use and grip strength. The half-dose group improved less, so the benefit tracked the dose.

Fungki delivers 1,000mg of Reishi per cup: the exact dose shown effective in this trial.

2. Lion's Mane · the mood study

In a 4-week double-blind study, the women who took Lion's Mane daily scored significantly lower on a standard depression scale than the placebo group, and reported feeling less irritable and anxious.

Fungki delivers 1,000mg of Lion's Mane 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.

Each result showed up at full, consistent doses. That is exactly why every cup of Fungki delivers 3,000mg of organic fruiting body mushroom: 1,000mg each of Lion's Mane, Reishi, and Cordyceps. The highest dose on the chart, at the lowest price per gram in the category.

Rainbo's Fungki vs. The Biggest Competitor

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 has 100% organic fruiting body, dual-extracted mushrooms, with verified beta-glucans on every batch. The most potent coffee alternative on the market
