Think way back. Like even before that. Ancient civilizations fueled themselves with meat. If it worked for them, it can definitely help you power thru. You may not be crossing treacherous seas, but endless to-dos, kid activities and trying to squeeze in a workout can feel just like it. Based on the Link family signature recipe, our Original Beef Jerky is marinated in a special blend of herbs and spices and slow cooked over hardwood smoke for that timeless flavor legions of jerky fans love. Made with 100% premium beef, each serving is packed with 10g of protein and no added MSG** or nitrates/nitrites. Jack Link's Original Beef Jerky is 96% fat free and packed with taste. It's enough to satisfy the entire family! Share a bag on family movie night, bring it to the soccer game for a snack or toss a bag in the car for when the whole gang is hungry. When we open a bag it hardly lasts three minutes, but once open, be sure to refrigerate or eat your beef jerky within three days. **Except for that naturally occurring in soy sauce, hydrolyzed corn protein, and yeast extract.
