My boy’s age is 4 and I bought it to strengthen his immune system against colds and flus. Not 100% sure if it helped, it feels like he was less sick this winter. It’s potent with good ingredients. Has no taste. One bottle lasts about 2 months. It causes no allergic reaction. It’s a good brand and a great choice for a kid. Haven’t had any complaints from my boy. It comes wrapped up really well in the shipping box.
