Muy fáciles de digerir

He consumido muchas marcas de geles energéticos y estos se digieren muy fáciles y son agradables para consumir. Hay otros que hostigan y son difíciles de tragar. Estos son muy líquidos y con balance perfecto de azúcar. He consumido 4 y hasta 5 en una media maratón sin ningún trastorno de estómago. No necesitan agua para consumirse
