Fast Bar is vegetarian, not vegan. Our bars contain plant-based protein and are made with honey. 

L-Nutra is working to ensure that all of our products are and remain GMO- free.

Fast Bars are gluten-free. However, they are manufactured on equipment that also processes wheat, so we recommend you review the list of ingredients here: nutrition information. 

L-Nutra is concerned about cross-contamination and we take the quality of our products seriously. As such, we meet or exceed current Good Manufacturing Practices (cGMPs) as well as applicable regulatory standards. Please read our nutrition information for more on potential food allergens.

Fast Bar is not formulated nor designed with soy ingredients.  However, they are manufactured on equipment that also process soy. Importantly, these facilities follow or exceed the current Good Manufacturing Practices (cGMPs) which ensure there are allergen control programs in     place. Please read our nutrition information for more on potential food allergens.

Fast Bars are dairy-free. However, they are manufactured on equipment that also processes milk or products containing milk, so we recommend you review the list of ingredients here: nutrition information.

Each bar contains 200 – 210 calories (equivalent to one serving).

Fast Bar is high in plant-based fat because it contains a whole serving of nuts. Nuts are an important source of healthy fats, which slow the absorption of the sugar to keep the glycemic index of the bar low and not break your overnight fast.*  The low glycemic index of Fast Bar was independently tested and confirmed.

* Benefits seen in a randomized, controlled study in 105 adults after a 15-hour overnight fast comparing the glucose and ketone results every hour for 4 hours in the Fast Bar group, breakfast group and water-fast group. Click here to read the published scientific article.

Fast Bar was designed with the same technology as ProLon’s L-Bars, but there are slight differences in size, calorie count and overall sugar content. Due to the carefully formulated macro and micro-nutrient ratios of the individual bars, they’re not intended to be interchangeable and should only be used as directed.

The information regarding the natural flavors in our recipe is proprietary, which allows us to keep our product delicious and unique. All ingredients in Fast Bar are Generally Recognized as Safe under the FDA.

It’s unlikely that the bar causes constipation. Constipation arises for many reasons, including dehydration, medication use, and lack of physical activity. The small amount of fiber in Fast Bar can actually help alleviate constipation when caused by insufficient dietary fiber. If your symptoms are severe or don’t resolve on their own, please talk to your medical provider. 

Fast Bar can be used as an occasional healthy, convenient snack by anyone, including during pregnancy and breastfeeding. However, to be clear, we don’t recommend any type of fasting during pregnancy or breastfeeding. Pregnancy and breastfeeding have special nutrient requirements and fasting of any kind may take away from the opportunity to consume the required nutrients.
