Chia protein, derived from chia seeds (Salvia hispanica L.), is increasingly marketed as a functional ingredient for athletic and exercise support, primarily due to its high protein content and favorable amino acid profile. Scientific evidence for its use in sports nutrition is limited but emerging. Chia seeds are rich in plant-based protein, dietary fiber, and omega-3 fatty acids, and some research suggests these nutrients may benefit exercise recovery and endurance.

A few small studies have investigated chia seed supplementation in athletes. For example, a 2011 study in Journal of Strength and Conditioning Research found that chia seed loading (providing about half of daily carbohydrate intake from chia) did not improve 10k running performance more than carbohydrate loading alone, although it did increase plasma alpha-linolenic acid (ALA, an omega-3 fatty acid) levels. Other studies have examined chia seeds' effects on satiety and metabolic health, but not specifically chia protein or direct athletic performance outcomes.

Overall, while chia protein provides a complete amino acid profile and is a plant-based protein alternative, its direct benefits for exercise performance, muscle recovery, or endurance are not well established in the scientific literature. Most evidence is extrapolated from the nutritional composition of chia seeds rather than rigorously controlled trials on chia protein supplementation in athletes. Therefore, scientific support exists but is limited (rated 2/5), and more targeted research is needed.
