  • Improves the quality of recovery after periods of overwork.
French Mush compléments alimentaires à base d'extraits de champignons médicinaux biologiques fabriqués en France - abonnement sur-mesure Dosage and use
  • In capsules : 2 to 4 per day, preferably in the evening, with a large glass of water or a warm infusion.

  • In powder : 1 to 2 g per day, to mix in a hot drink (herbal tea, plant-based milk, cocoa) or cold (smoothie, yogurt).

  • Recommended course : 60 to 90 days, for a complete effect on sleep, stress, and immunity.


The Reishi can sometimes interact with certain treatments, particularly anticoagulants or those related to hypertension. If you have any doubts, do not hesitate to talk to your doctor.


If you are pregnant, breastfeeding, or undergoing medical treatment, it is recommended to seek your doctor's advice before use.

Can I combine multiple mushrooms?

Yes, Reishi works perfectly in synergy with other extracts:

Each combination acts on a complementary axis for a global and sustainable balance.

We talk about synergy when several mushrooms work together in a complementary way, enhancing their respective effects for a more complete and balanced action

Frequently Asked Questions

Are mushrooms psychoactive?

No, these are dysfunctional mushrooms. Some mushrooms are gastronomic: porcini, chanterelle, button mushroom... Others are medicinal: Chaga, Lion's Mane, Cordyceps, Reishi. And finally, some are hallucinogenic. But they have nothing to do with each other. Comparing medicinal mushrooms with magic mushrooms is like comparing alcohol with water. :)

What is the difference between powders and capsules?

The powders and capsules are essentially the same products. The difference lies in the intake and dosage. The powders are to be mixed with a drink or food. The capsules are to be swallowed with a glass of water.

Where do mushrooms come from?

The greatest added value of French Mush lies in close collaborative work between our growers and our laboratories. Our mushrooms are exclusively sourced from European channels, mainly in France and Finland, known for their expertise, high quality standards, and controlled growing conditions.

What is the difference between powder and extracts?

French Mush uses extracts. These are dried mushroom powders that are then extracted. Indeed, the interesting active ingredients of mushrooms cannot be bioavailable in the human body without prior extraction. For your information, 300 grams of dried powder are needed to make 30 grams of extracts. Therefore, French Mush products are very concentrated and among the most effective in Europe.

Are there any side effects or contraindications?

There are no side effects from consuming mushrooms. There may be contraindications with certain medications (anticoagulants, hypertension); do not hesitate to seek advice from your doctor. The product is not recommended for pregnant and breastfeeding women.

Can I consume multiple mushrooms at the same time?

Yes, absolutely, there is indeed a synergistic effect when consuming different mushrooms, particularly on digestion, immunity, and vitality.
