Composition of Authentic Nutrition products
The list of ingredients and the nutritional values of each of our products can be found in each of the product sheets, in the "nutritional values" and "composition / advice" tabs.
No, Authentic Nutrition products are gluten-free, including Flapjack Energy Bars and Sport Chips Cheese/Onion Protein Chips.
Exception: Sport Chips Paprika Protein Chips, which contain gluten in the flavor.
No, Authentic Nutrition products do not contain palm oil, including our energy or protein bars and Sport Chips.
No, Authentic Nutrition products do not contain glucose syrup, but they do contain fructose, maltrodextrin, and agave syrup, depending on the product.
Our energy bars, Flapjack, post-workout chips (Sport Chips), pre-workout drinks and creams (Carbo Powder, Carbo Start), and recovery drinks are perfectly suitable for vegetarians.
However, our exercise drinks, gels, and gummies (Booster +, Boost Gel, Boost Gums), and protein bars (Recovery Bars) are not suitable for vegetarians because they contain animal-derived BCAAs or hydrolyzed beef collagen.

Yes, Authentic Nutrition products all comply with the European anti-doping standard NF EN 17444, which came into force in June 2021 (replacing the NF V94-001 standard).
Electrolytes are mineral salts that circulate in the blood and are present in cells: sodium, potassium, calcium, and magnesium. Some of these mineral salts are lost during physical exertion (particularly through sweat). An intake during exercise is therefore strongly recommended, particularly in cases of intense heat and/or prolonged exercise.
La maltodextrine est un sucre complexe composé d’une longue chaîne de molécules de glucose ou de fructose. Contrairement aux sucres simples (aussi appelés sucres rapides), tel que le glucose, le fructose, le lactose, le saccharose, la maltodextrine permet un apport plus constant en sucre et évite ainsi les grosses variations en glucide (hypoglycémie/hyperglycémie). La maltodextrine a également un goût moins sucré, plus neutre que les sucres simples, ce qui évite les écœurements.
BCAAs (Branched Chain Amino Acids) are branched-chain amino acids composed of leucine, isoleucine, and valine. These are essential amino acids that the body cannot produce. Consuming them during prolonged exercise reduces the breakdown of active muscles, minimizes the breakdown of glycogen stores, and reduces the phenomenon of "central nervous fatigue."
Carbohydrates refer to the sugar molecule. It is another name for carbohydrates, which are divided into simple and complex carbohydrates.
Glycogen is glucose stored by the liver and muscles, forming a significant reserve of glucose for the body. Muscle glycogen is primarily used to provide glucose during physical activity. Liver glycogen is used to provide glucose to the brain, its sole source of energy.
Collagen provides great elasticity and allows tissues to be more resistant. It participates in tissue regeneration and reduces joint pain.
Antioxidants are molecules naturally present in many foods that prevent or slow oxidation by neutralizing free radicals. Free radicals damage our cells, including DNA, and are responsible for cell aging.
Examples of antioxidants: vitamins A, C, E, zinc, selenium, manganese, etc.
The glycemic index, also called "dextrose equivalent," represents the speed with which consumed carbohydrates are digested and reach the bloodstream. This gives all foods a rating between 0 and 100. The base rating, 100, is glucose/dextrose. The higher the dextrose equivalent, the more quickly assimilated sugar the product contains. The lower the dextrose equivalent, the more gradually the product will be absorbed.
Our products have dextrose equivalent ratings between 12 and 20 and are therefore easily assimilated by the body.
To learn more, please read our article on the glycemic index.
An isotonic drink has the same concentration as blood or blood plasma. This means that its absorption will be optimal in the intestines. It will quickly leave the stomach for optimal efficiency and digestive comfort. This can also be referred to as the drink's osmolarity or osmotic concentration.
An isotonic drink contains roughly the same amount of carbohydrates, water, and salt as blood.

Authentic Nutrition Pre-Workout Products
Dilute 200g of Carbo Powder in 1 to 1.5 liters of water each day of refilling.
Refilling is done over 3 days, on D-4, D-3 and D-2. No refilling the day before the race. Consume 1 to 1.5 liters of water with the refill dose per day. Consume regularly in small quantities (15 cl max) spread throughout the day.
We actually recommend recharging on D-4, D-3 and D-2 and stopping the day before the race so as not to overload your body before the race.
If stored in its original packaging, away from heat and humidity, and the box is closed properly after each use, Authentic Carbo Powder can be used until the date indicated on the box, including after opening.
- For a pre-workout snack: Dissolve 60g (5 heaped tablespoons) of powder in a bowl and add 20ml of water.
- For breakfast: Dissolve 120g (10 heaped tablespoons) of powder in a bowl and add 40ml of water.
It is recommended to consume the energy cream 15 to 30 minutes before starting your physical effort.
Authentic Nutrition's exercise products
Dilute 40g of powder in 500ml of water - that's 2 measuring spoons or 3 heaped tablespoons. In hot conditions, dilute further.
It is recommended to drink 150 to 200 ml of sports drink every 15 minutes.
Don't wait until you're thirsty to hydrate!
We recommend preparing your sports drink at the last minute. However, you can still prepare it 12 hours in advance and store it in the refrigerator (temperature <10°C) until ready to use.
If stored in its original packaging, away from heat and humidity, and the box is closed properly after each use, the Authentic Booster + can be used until the date indicated on the box, including after opening.
It is recommended to take 25 to 30 g per dose, one dose every 45 minutes.
Authentic Energy Fluid Gel should be stored for at least 3 months, away from light and in a cool place (refrigerated if possible). The gel may potentially lose some vitamin C, as this vitamin is very sensitive to light and heat, but all other macro- and micronutrients will remain unchanged for 3 months after opening.
Authentic Nutrition Post-Workout Products
Dilute 60g of Authentic Récup powder (8 doses) in 250ml of cold water. You can also dilute 30g in yogurt or fromage blanc.
It is recommended to drink 250 ml of recovery drink immediately after exercise (between 0 and 30 minutes later).
The recovery drink, Authentic Récup, can be prepared a few hours in advance BUT must be kept cool before consumption so as not to alter its properties.
If stored in its original packaging, away from heat and humidity, and the box is closed properly after each use, Authentic Récup can be used until the date indicated on the box, including after opening.
Recovery Bars are sold in packs of two 40g servings. Depending on the duration and intensity of your workout, consume one or two servings.
One 40g serving = 9g of protein (including 20% collagen) = 1 egg or ½ steak or ½ salmon fillet.
For optimal recovery, it is recommended to take recovery products (drink, bar or chips) within 30 minutes of finishing your training or race.
