Effervescent is best, it works!
By S. Chung on Reviewed in the United States on June 17, 2025
I grew up using effervescent vitamin C, and I've found that effervescent absorbs much faster and better than typical pills or powders. This effervescent formula combines multiple vitamins, the key ones for flu/cold are C, D, and Zinc (backed by research studies). It also contains herbs like echinacea that are also supposed to bolster the immune system. I take one of these as soon as I start to feel a tiny whiff of symptoms, it works really well to nip the illness in the bud. My kid said it upsets his stomach (I've never had an issue with it) so for some you may need to take it with some food. The taste is good, it smells good, and it works really well for those starting to get flu/cold symptoms. I highly recommend it if you can afford it, as it is quite expensive compared to other vitamins you can get off the shelf.
