This bar also contains KSM-66® ashwagandha (the most clinically studied form of the adaptogen), which has been shown to improve body composition by increasing muscle mass and lowering body weight.
Research backs this up, too—a 2015 study of men aged 18-50 found that supplementing with ashwagandha for eight weeks led to significantly greater increases in arm muscle size, and increased strength on the bench-press and leg-extension exercises compared to the placebo.
Plus, the men who took ashwagandha had reduced exercise-induced muscle damage, and they lost 3.5% of their body fat (compared to 1.5% in the placebo group).
All in all, the high protein, low sugar, and recognizable ingredients make Atlas Protein Bar our number one pick for the best protein bar for muscle gain.
Protein Bar FAQs
Is It OK to Eat Protein Bars Every Day?

Even if you are not working out every day, healthy protein bars can be a great snack to bridge the gap between meals.

How Do I Choose the Best Protein Bars?

Are Protein Bars Worth the Hype?
Protein bars can be a great addition to your diet—especially if you exercise regularly, don’t get much protein during mealtimes, or get hungry between meals.
