What Are Probiotics and Why Are They Important?
Probiotics are living microorganisms that, when consumed in adequate amounts, provide health benefits. These "good" bacteria help maintain the balance of the gut flora, improving digestion, the immune system, and overall well-being.
For athletes, especially those who participate in demanding sports such as skiing and snowboarding, probiotics can make a significant difference in performance and recovery.
Health Benefits of Probiotics
1. Improved Digestive Health
Probiotics help balance the gut microbiota, reducing problems such as bloating, gas, constipation, and diarrhea. A healthy digestive system is essential for optimal nutrient absorption.
2. Strengthened Immune System
Approximately 70% of the immune system is located in the gut. Probiotics strengthen natural defenses, reducing the incidence of respiratory infections and flu.
3. Reduced Inflammation
Certain probiotic strains have anti-inflammatory properties that may help reduce chronic inflammation in the body.
4. Improved Mood
The gut-brain axis means that a healthy microbiota can positively influence mood, reducing anxiety and improving mental health.
Probiotics and Athletic Performance
For winter sports enthusiasts, probiotics offer specific benefits:
Reducing Respiratory Infections
Studies show that athletes who take probiotics have up to 40% fewer upper respiratory tract infections. This is crucial when planning a ski getaway in Andorra or the Pyrenees and you cannot afford to get sick.
Improved Muscle Recovery
A healthy microbiota improves the absorption of proteins and essential nutrients, speeding up recovery after intense days on the slopes.
Reducing Oxidative Stress
Intense exercise generates free radicals. Certain probiotic strains help reduce oxidative stress, protecting cells from damage.
Optimizing Hydration and Electrolyte Absorption
Probiotics improve intestinal barrier function, optimizing the absorption of water and electrolytes, which is essential at high altitudes where dehydration is more common.
The Best Probiotics of 2026
1. Lactobacillus Acidophilus
Benefits: Improves lactose digestion, reduces bloating, and strengthens the immune system.
Ideal for: Athletes with lactose intolerance or digestive problems.
Recommended dose: 1–10 billion CFUs per day.
2. Bifidobacterium Lactis
Benefits: Supports the immune system, improves intestinal function, and reduces inflammation.
Ideal for: Preventing colds and flu during ski season.
Recommended dose: 10–20 billion CFUs per day.
3. Lactobacillus Rhamnosus GG
Benefits: Prevents and treats travelers’ diarrhea and strengthens the intestinal barrier.
Ideal for: Traveling to ski destinations abroad (France, Italy, Switzerland).
Recommended dose: 10 billion CFUs per day.
4. Saccharomyces Boulardii
Benefits: An antibiotic-resistant probiotic yeast, excellent for diarrhea and acute digestive problems.
Ideal for: Recovery after antibiotic treatment.
Recommended dose: 250–500 mg twice a day.
5. Lactobacillus Plantarum
Benefits: Reduces intestinal inflammation, improves nutrient absorption, and has antioxidant properties.
Ideal for: Endurance and high-intensity athletes.
Recommended dose: 10 billion CFUs per day.
6. Bifidobacterium Longum
Benefits: Reduces stress and anxiety, improves mental health, and strengthens the intestinal barrier.
Ideal for: Managing pre-competition stress or travel.
Recommended dose: 1–10 billion CFUs per day.
7. Streptococcus Thermophilus
Benefits: Improves lactose digestion and produces lactic acid, which inhibits pathogenic bacteria.
Ideal for: Combining with other probiotics for a synergistic effect.
Recommended dose: 1–10 billion CFUs per day.
How to Choose the Best Probiotic
1. CFU Count (Colony-Forming Units)
Look for supplements with at least 10–50 billion CFUs per dose. For athletes, higher doses (50–100 billion) may be beneficial.
2. Strain Diversity
Multi-strain probiotics are often more effective than single-strain probiotics. Look for formulas with 5–10 different strains.
3. Resistance to stomach acid
Choose probiotics with delayed-release capsules or strains resistant to stomach acid to ensure they reach the intestines alive.
4. Expiration Date and Storage
Verify that the product guarantees bacterial viability through the expiration date. Some require refrigeration.
5. Certifications and Quality
Look for products with third-party certifications (GMP, NSF, USP) that guarantee purity and potency.

When and How to Take Probiotics
Best Time of Day
Most experts recommend taking probiotics on an empty stomach or 30 minutes before meals, although some studies suggest that taking them with food may improve the survival of certain strains.
Treatment Duration
- General maintenance: Continuous use
- After antibiotics: During treatment and for 2–4 weeks afterward
- Sports season: Throughout the entire ski season (3–6 months)
- Acute digestive problems: 1–2 weeks
Tips for Maximizing Effectiveness
- Combine with prebiotics: Fibers that feed beneficial bacteria (garlic, onions, bananas, asparagus)
- Maintain a balanced diet: Rich in fiber and low in processed sugars
- Avoid excessive alcohol: It can damage the microbiota
- Stay well hydrated: Especially important at high altitude
- Reduce stress: Chronic stress negatively affects the microbiota
