These pack everything in a tablet the ingredients and quality are great. The tablets might be hard for some but I was okay taking them. Taste is a little funky but worth it for the benefits & health!

good product!
Verified purchase
This wellness formula packs a lot of nutrition in one bottle! You would have to pay a lot to get all the ingredients in here separately. I would take it when I was feeling a little down on health and it does help one feel a little perkier. I think the amount and quality of ingredients seems very good.

Great Immune Support, works everytime
Verified purchase
I've been using this for a number of years. Every time I feel I might be coming up with a flu, I take 3 tablets. Sometimes, it stops the flu completely and the next day I'm good to go. When the flu is particularly strong I continue according to the usage directions and usually feel better within a week. Have recommended to many friends

great for immunity support and onset of cold sores!
Verified purchase
i have yet to find a product that works as well as this one. If i get sick, it helps me recover quicker. but if i take it BEFORE i get sick (when im feeling run down and around people who are sick), it boosts my immunity and i dont get sick. MOST IMPORTANTLY- if i feel a cold sore coming on, it is the ONLY thing that works and makes it go away completely without even having an outbreak. it’s simply magic!

The ingredients are strong - this was the reason I chose this product and also heard good feedback about it from ohers. Hoping it will help me during the cold season. I believe in the brand's quality. The tablet size is good enough for me and I like that there are plenty of them.
