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!

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!

daily wellness for me
Verified purchase
I started taking this product post lyme disease almost 15 years ago. I take it for daily support and as soon as I feel slightly off I take the maximum dosage and it keeps me from greater dis-ease every time. Source Naturals is one of my go to brands/company.

This Wellness Formula is my go-to at the first sign of a cold—it really seems to help me bounce back faster. I take the tablets as directed, and they've become a trusted part of my immune support routine. I appreciate the comprehensive blend of herbs and vitamins. It's a powerful, effective product I always keep on hand.

Think it works..
Verified purchase
Was recommended this by a friend and I take this every time I’m sick cause it has all the minerals and vitamins you need in the same pill so I think it does shorten my cold! Easy to take and I like having the convenience of not having to buy five different items

This Wellness Formula from Source Naturals has been my go-to immune support for years, especially during cold and flu season. At the very first sign of a scratchy throat or fatigue, I start taking it, and I genuinely believe it helps me either fight off illness completely or recover much faster. The tablet size is manageable, and I appreciate the comprehensive blend of herbs, vitamins, and minerals that work synergistically. It's a trusted, high-quality product that I always keep stocked in my medicine cabinet for when I need that extra immune boost.

Great
Verified purchase
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.
