Founded in 2010, Richmond, Virginia-based Health Warrior makes protein powder, bars and muffins rich in plant-based nutrients and so-called "superfoods" such as chia seeds.

Health Warrior will become part of PepsiCo's HIVE division, created to house small and emerging brands. The beverage and snack giant did not disclose the price of the acquisition.

PepsiCo and larger rival Coca-Cola Co have made a string of acquisitions aimed at offering healthier products.

This year, PepsiCo bought carbonated drink-machine maker SodaStream for $3.2 billion (2.5 billion pounds) and baked fruit and vegetable snack maker Bare Foods Co for an undisclosed sum.
