LifeAID Beverage Company has gained an investment from private-equity firm KarpReilly, which will help the drinks firm to fund its growth. 

The total amount of the investment has not been disclosed.

According to the company, this investment represents a significant minority position.

LifeAID's line of products includes FitAID, FocusAID, PartyAID, TravelAID, GolferAID, and the FitAID Fuel Pouch.

LifeAID co-founder and president Dr. Aaron Hinde said: "The team at KarpReilly understands current consumer trends and passionately supports the functionality and nutritional value of our products. Additionally they were impressed with our go-to-market successes in non-traditional channels such as golf courses and CrossFit gyms."

"Functional beverages represent an evolution."

LifeAID CEO Orion Melehan added: "KarpReilly has a long-view approach and an impressive track record of scaling consumer brands. With their capital investment and imitable expertise, we now have greater resources to continue on our roadmap.

"We are building our brand to serve consumers with functional products that fit their lifestyle. There is a momentous shift happening in the beverage market. Consumers are waking up to what they are putting in their body, demanding alternatives to traditional sports drinks, energy drinks and sodas. LifeAID is the answer."

KarpReilly co-founder Allan Karp said: "We were impressed with what Orion, Aaron and the entire team has done in such a short time with the resources they had available.

"LifeAID is full of tremendous promise and is a great addition to our beverage portfolio. The writing is on the wall. Functional beverages represent an evolution, we are betting on the best suited team to lead that change."

Karp will join the LifeAID board.

The proceeds from this investment will expand the LifeAID sales/marketing teams, and support its growing footprint in conventional retail outlets. 

Currently, the brand is sold in The Vitamin Shoppe, H.E.B, and Whole Foods, and at several Safeway/Albertsons outlets.
