The benefits of Reishi

French Mush Quality

French Mush offers biosourced mushroom extracts. Making our products assimilable and ultra-concentrated. It's important to note that 90% of the mushroom-based products you'll find online are counterfeit. Product quality depends on traceability and extraction. Don't be fooled into buying basic mushroom powder. For example, you need 4kg of mushrooms to obtain 30 grams of extract.

Story ?

Reishi has been the best-known mushroom in traditional Chinese medicine for thousands of years. It is nicknamed the mushroom of immortality. Due to its rarity, its use was reserved exclusively for Chinese emperors.

Taste and use

Reishi tends to be slightly bitter in food and drink. This bitterness is a sign of its quality. Don't hesitate to add fruit or sugars to reduce its bitterness. We recommend that you use the products as part of a cure lasting a minimum of 30 days and, if possible, 90 days. You can use different mushrooms at the same time for a synergistic effect.

Immunity, relaxation, sleep?

The Reishi mushroom, often referred to as "the queen of mushrooms", is renowned for its soothing properties and its support for a better quality of sleep.

Reishi's active compounds, triterpenoids, can benefit our parasympathetic nervous system, promoting relaxation and restful sleep.

In addition, this mushroom is rich in polysaccharides and beta-glucans, complex carbohydrates known to boost the immune system.

The presence of triterpenoids also contributes to immune health.

So, for relaxation, quality sleep and a robust immune system, Reishi could be an excellent natural ally.

Easy to integrate into your preparations, whether hot and cold drinks or culinary recipes, this mushroom is known for its effects of relaxation, relaxation and preparation for sleep. 

Going beyond simple psychological comfort, Reishi powder is also an undisputed force for strengthening your natural defenses. Its anti-inflammatory properties play a key role in preserving and optimizing general well-being. 

With each spoonful of Reishi en poudre French Mush, treat yourself to a dose of serenity and robustness.

Reishi powder, a powerful ally to strengthen your immune system!

Reishi, often referred to as the "king of medicinal mushrooms", is an invaluable source of benefits for health. In particular, its ability to strengthen the immune system is increasingly recognized. 

But how does Reishi powder interact with your body to provide you with these benefits?

By the essential components of Reishi

  • Polysaccharides : They play a crucial role in strengthening the immune system. Among these, beta-glucans are particularly effective in stimulating the activity of immune cells. It is by extracting these complex carbohydrates that French Mush makes their assimilation possible by your body.
  • Vitamins and minerals : Reishi is rich in several vitamins and minerals, including calcium, selenium, magnesium, potassium and iron. These nutrients are essential for the proper functioning of the metabolism.
  • Essential fatty acids : They contribute to the bioavailability of nutrients, thus helping the body to better absorb and assimilate the beneficial compounds of the mushroom.
  • Trace elements : They act as catalysts in various bodily functions, including strengthening the immune system.

For its benefits on immunity

  • Anti-inflammatories : The natural components of Reishi have properties that are said to help reduce inflammation, thereby promoting a healthy body environment.
  • Stimulation of defenses : By regularly consuming Reishi powder, you stimulate and strengthen your immune defenses, thus preparing your body to effectively fight pathogens.

The Reishi powder is a practical and effective way to benefit from all of these essential nutrients. Integrate it into your daily routine to support your immune system and benefit from its many medicinal benefits.

What role does the immune system play in your ability to relax and unwind?

The immune system is mainly associated with the body's defense against pathogens. However, it is intricately linked to the rest of the body, including the nervous system, and can indirectly influence your ability to relax. 

Here's how the immune system interacts with your ability to relax:

  • Inflammatory response and stress : A chronic inflammatory response, which may be due to poor immune function, may be associated with high levels of the stress hormone cortisol. Chronically high levels of cortisol disrupt sleep, increase anxiety, and decrease your ability to relax.
  • Interaction with the nervous system : The immune system and the nervous system communicate continuously. For example, certain pro-inflammatory cytokines can affect mood and behavior. An immune imbalance can therefore indirectly influence your emotional state and your ability to relax.
  • The gut-brain axis : The immune system plays a key role in gut health, and the gut is closely linked to the brain. Gut dysbiosis or inflammation affects the neurochemical balance of the brain, influencing mood and relaxation.
  • Effect on energy : Increased immune activity, such as during an infection, can drain energy, making a person more tired or lethargic.
  • Feeling of well-being : A healthy immune system contributes to an overall sense of well-being, which helps with relaxation. Conversely, constantly feeling sick or weak makes it more difficult to relax.

It is therefore clear that the immune system, although not directly responsible for your ability to relax, plays an indirect role in influencing several factors that affect access to overall relaxation. 

The Reishi mushroom powder helps maintain good immune health and contributes to better emotional and physical balance, thus promoting relaxation.

Why choose Reishi Mushroom Extract in powder form?

The answer is simple and multiple at the same time. First of all, consuming Reishi powder offers unparalleled versatility in uses. You can easily mix it in a glass of water, sprinkle it on a dessert, incorporate it into a smoothie, fruit juice, or even mix it with your teas and infusions. 

It only takes a teaspoon to benefit from the active ingredients of Reishi. 

Thanks to the expertise of French Mush, you consume a concentrated extract which comes from mushrooms cultivated via organic farming, thus promoting its assimilation and guaranteeing that the entire spectrum of Reishi (mycelium and fruiting body) retains all its nutritional and therapeutic properties. 

Our food supplement is 100% vegan and, as in its capsule form, the powder allows you to fully benefit from the medicinal virtues of the mushroom.

Given the power of this adaptogenic mushroom, French Mush does not recommend this dietary supplement for children as well as pregnant and breastfeeding women.

Frequently Asked Questions

Are mushrooms psychotropic?

No, these are so-called functional mushrooms. Some mushrooms are gastronomic: porcini mushrooms, chanterelle mushrooms, button mushrooms, etc. Others are medicinal: Chaga, Lion's Mane, Cordyceps, Reishi. And finally some are hallucinogenic. But they all have nothing to do with each other. Comparing medicinal mushrooms with magic mushrooms is the same as comparing alcohol with water. :)

What is the difference between powders and capsules?

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 is the collaborative work between our growers and laboratories. On average our mushrooms come 35% from France, 25% from Holland, 20% from Finland and 20% from China.

What is the difference between powder and extracts?

French Mush uses extracts. This is dried powder of mushrooms which are then extracted. In fact, the interesting active ingredients of mushrooms cannot be bioavailable in the human body without first extraction. For information, 300 grams of dried powder are necessary to make 30 grams of extracts. French Mush products are therefore 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 drug treatments (anti-coagulants, hypertension). Do not hesitate to ask your doctor for advice. The product is not recommended for pregnant and breastfeeding women.

What is the difference between classic mushroom powder and French Mush powder + extract

The really interesting active ingredients in mushrooms are called polysaccharides and beta glucans. However, these molecules cannot be assimilated by the human body in their raw state. In fact, we do not have naturally present receptors to receive them. For this reason it is necessary to carry out an extraction in order to “break” the molecules and make them assimilated in our body. At French Mush we use different extraction techniques depending on the mushroom, sometimes with hot water sometimes with ultrasound but always naturally and biologically. For example, to make 30 grams of powder + extract of Lion's Mane or Reishi you need 3KG of raw mushroom then 400 grams of dried mushrooms to ultimately obtain 30 grams of powder + extracts. French Mush products are therefore highly assimilable and concentrated.
