Unsure of how well it works yet as I鈥檝e only just tried it today.. I got the elderberry because I鈥檓 not a fan of orange wondering if the orange would鈥檝e been better because this one tastes absolutely HORRIBLE!!! I have to plug my nose and chug it down because it鈥檚 so disgusting!! I hope it works because I definitely do not wanna have to be drinking these for too many days 馃あ
