BOOST: a natural alternative to coffee
Coffee is a beverage that you enjoy for its stimulating effect. However, do you know that it can cause side effects such as nervousness, digestive issues, or sleep disturbances?
If you're looking to maintain your energy without these inconveniences, there is a natural alternative to coffee.
French Mush presents BOOST, a drink formulated from natural ingredients, designed to offer you gentle and lasting stimulation without the undesirable effects of coffee. This soluble powder combines the benefits of chicory, guarana, and the functional French adaptogenic mushrooms that are The cordyceps and The lion’s mane.
It is a coffee substitute that allows you to support your physical and mental vitality while respecting your body's balance.
Why replace coffee?
Drinking a cup of coffee is part of our habits. It wakes you up, stimulates, and accompanies the start of the day as well as the end of meals. Yet, more and more people are looking to reduce or even stop their consumption. And it's no coincidence!
Energy that rises... then falls
Caffeine is known for the speed of its effect. It works by blocking adenosine, a molecule that signals our body that it's time to rest. The result: you feel awake, focused, and sometimes even euphoric. But this feeling doesn't last. After a few hours, the caffeine wears off and leaves you with a feeling of fatigue sometimes more pronounced than before.
And the more coffee you consume, the more frequent this phenomenon becomes.
Significant side effects
Beyond this sudden drop in energy, coffee can cause other inconveniences:
- Nervousness, palpitations, feeling of restlessness...
- Sleep disturbances, even if the last cup was several hours ago.
- Digestive irritations, especially when consumed on an empty stomach.
- Gradual dependence, with a tolerance that pushes you to increase doses to feel the same effect.
For many, these side effects outweigh the benefits. That's why French Mush offers you a gentler, more balanced coffee alternative that is better suited to the body's natural rhythms.
To replace coffee without depriving yourself
A coffee substitute should not make you give up the pleasure of enjoying a hot, smooth, and energizing drink. We offer you to support your vitality differently: in a more stable way, more respectful of the body, without the highs and lows caused by caffeine.
It is also an opportunity to discover new flavors, new rituals, and to reconnect with a healthier way of listening to your needs.
It is with this in mind that we designed BOOST: to offer an alternative to coffee that is both effective and pleasant.
BOOST, the natural coffee substitute
Designed as a concrete response to the limits of coffee, BOOST is the result of a complete and natural formulation that brings together four carefully selected ingredients to accompany your days without jarring your body.
A very effective plant synergy
Each ingredient in BOOST plays a specific role to replace coffee and it is their complementarity that makes the difference.
Chicory
Long used as a coffee substitute, chicory offers a round and slightly caramelized taste reminiscent of coffee… without caffeine. Naturally rich in inulin, a plant-based prebiotic, it supports the intestinal microbiota and contributes to digestive comfort. A delicious base that feels good from the first sip.
Guarana
Native to the Amazon, guarana contains guaranine, a plant-based energizing substance known for its progressive release. Unlike coffee, its effect does not peak but spreads consistently. Result: stable energy, without excessive excitement or sudden crash.
The cordyceps
This functional mushroom has been used for centuries in traditional Chinese medicine. It is recognized for its tonifying properties, particularly on the physical level. The cordyceps supports vitality, endurance, and recovery, making it a valuable ally for intense days or regular physical activities.
The lion’s mane
Also called “The lion’s mane,” this mushroom is appreciated for its effects on concentration, memory, and cognitive function. It promotes a stable state of attention, without agitation. A natural support for phases of intellectual work, creation, or decision-making.
A functional blend respectful of your health
BOOST is formulated with ingredients from organic farming, with no added sugars, gluten-free, and without additives. A 100% plant-based drink, formulated in France, that respects both your body, the environment, and your quality standards.
An alternative to coffee, yes. But above all, a new generation drink, to bring healthier energy and well-being to your body and mind.
Coffee vs BOOST
Are you hesitant to replace coffee but unsure if BOOST is really up to the task? Let's compare the two. On one side, a drink well-rooted in habits. On the other, an alternative designed to respect your natural rhythms, without compromising on vitality.
Criteria | Traditional coffee | BOOST by French Mush |
---|---|---|
Source of energy | Pure caffeine, fast action | Natural guarana, gradual action |
Effect over time | Energy peak followed by a crash | Gentle and lasting stimulation |
Impact on digestion | May irritate the stomach, especially on an empty stomach | Chicory rich in prebiotics, digestive support |
Side effects | Nervousness, tremors, sleep disturbances | No excessive stimulating effect, no dependency |
Origin of ingredients | Variable, often poorly traceable | 100% natural, organic, traceable, controlled origin |
Functional components | Caffeine only | Synergy chicory + guarana + The cordyceps + The lion’s mane |
Formulation | Simple (caffeine) | Complete, multi-benefits (energy, focus, digestion) |
Ritual | Sometimes a mechanical reflex | Mindfulness and well-being |
Suitable for everyone? | Not recommended in case of sensitivity | Softer formula, better tolerated daily |
Coffee offers an immediate boost, but it can quickly feel like an energy loan to be repaid a few hours later.
BOOST favors more regular stimulation, with benefits that go beyond mere alertness: concentration, digestion, vitality... all without overtaxing the body.
Switching drinks to replace coffee should not make you give up performance. It can also mean: choosing a healthier, smarter, more sustainable performance.
How to consume BOOST?
No need for a complicated manual or timed ritual. BOOST is a coffee substitute designed to integrate simply and naturally into your habits.
A quick preparation
Each sachet contains a soluble powder to mix with the liquid of your choice. For a standard dose (4 g), simply:
- Prepare a hot drink: water or plant-based milk at about 70°C (no more, to preserve the properties of the plant extracts).
- Add two level teaspoons of BOOST.
- Mix until completely dissolved.
- Enjoy. It's ready.
The taste is naturally mild and slightly roasted with a nice roundness in the mouth. You find notes reminiscent of coffee but without its bitterness.
A format that adapts to your desires
BOOST can be consumed:
- In the morning, to start the day off right.
- In the middle of the afternoon, to support energy and concentration until evening.
- Before a workout session, as an alternative to classic boosters.
- In a smoothie for a delicious boost.
The recommended frequency
2 to 3 doses per day are enough to feel the effects. Each sachet contains 20 doses of 4 g.
BOOST is a dietary supplement that fits into a varied diet and a healthy lifestyle. It is not recommended for children, pregnant or breastfeeding women, or people under medication without medical advice.
Much more than a coffee substitute: BOOST, a wellness ritual
With BOOST, it's not just about regaining energy without the undesirable effects of coffee. It's about rethinking how you support your body and mind on a daily basis.
A complete functional beverage
BOOST is a synergistic formulation in which each ingredient plays a complementary role:
- Chicory supports digestion and the microbiota.
- Guarana stimulates without excess with a slow release of the energizing plant substance.
- The cordyceps promotes physical endurance and recovery.
- The lion’s mane improves mental clarity and cognitive functions.
It is a global, sustainable support that aligns with the needs of a body in motion. Coffee strains the body, BOOST accompanies and supports it.
A gourmet break that nourishes as much as it stimulates
Drinking coffee is often a reflex. Drinking BOOST means adopting a new way to take care of yourself. You take the time, you choose a drink that works deeply, and you allow yourself an energizing and beneficial break, both for the mind and the body.
Responsible consumption
BOOST is 100% plant-based, certified organic, made in France from traceable ingredients, gluten-free, with no added sugars and no artificial additives.
By choosing BOOST, you commit to a broader change in your consumption habits. You opt for a coffee alternative that introduces you to a new way to energize yourself while respecting your body, your rhythms, and your inner balance.
