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!

In my home, this supplement is more useful than medicine.
Verified Purchase
This is one of the supplements I continue to purchase. Whenever I feel a slight discomfort in my throat or nose, when I suspect I might have a cold, or when I feel fatigue and a weakened immune system, Wellness Formula is the supplement I take immediately. It has a strong garlic-like smell, but somehow that smell seems to be good for my body. I keep it on hand all year round, but it's especially useful during cold season. When I feel something's wrong, I take two tablets at a time before bed, or one after breakfast, lunch, dinner, or dinner, depending on how I'm feeling at the time. It's amazing how quickly my discomfort disappears. In my household, when I suspect I might have a cold, I prioritize Wellness Formula over other medications like cold medicine.

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

Vitamins to prevent colds
Verified Purchase
A friend in America recommended this to me. I have a child in daycare, so I always catch colds from them. I wasn't sure if it was working for a few months after I started taking it, but the other day my child caught influenza A, so I panicked and started taking three pills, and they didn't catch a cold at all! By the way, at first I was stingy and only took one pill a day, but I caught a cold when I was on one pill lol, so now I usually take two pills, and switch to three if cold bacteria appear in the house. The smell is quite strong, but it's packed with vitamins, so it seems good for your body.

For immunity
Verified Purchase
A good immune-boosting complex from Source Naturals, especially useful during cold and flu season. It contains vitamins A, C, and D, zinc, selenium, and herbal extracts such as echinacea, elderberry, and licorice. I take four capsules daily with food. After just a couple of weeks, I noticed that I was able to cope better with weather changes and was catching fewer colds. The capsules are quite large, but easy to swallow. A good option when you want to strengthen your body without taking dozens of separate supplements.
