Best supplement for immune support

By far the best supplement for when you start to feel a cold or flu coming on. If you catch it quickly at the first signs of getting something, and take two capsules every 4 hours, you can stop it in its track. I always keep a bottle on hand. Pricey but worth it.

Recommended to keep a bottle for “emergencies”

You must take this at the earliest onset of a cough or cold. And follow the dosage closely. It helped to arrest the progress of the cough and cold further which means you will receive over very fast. At the same time it is also useful to take whatever other possible steps like liposomal C, good quality honey etc. The size of the capsules is manageable.

fantastic product

I have used this when I feel something coming on several times and it works! You take 2 up to 5 times per day and for me, by the 2nd day, I feel better. You do have to do it right away when you have an inkling something is coming on. It's pricey, but worth it!

great

Our naturopath Dr recommended this for when we start feeling like a cold or flu is coming on. We go by the directions, and it stops whatever we are feeling right away. We have bought several bottles as my daughter has started using them too.

This is my emergency pill when i first feel a cold voming. The taste is meh but who cares it does an excellent job getting rid of the symptoms. The dosage on the bottle says to take 2 pills every 5 hours.

Really Works

The ingredients in this really work to keep me from getting sick if I take it as soon as I feel a cold coming on. I like the size of the bottle, because I like to keep it on hand.

A game-changer for seasonal sickness no more paracetamol!

I’ve been ordering these for a long time now and I swear by them. Usually, every time the weather changes, I get hit hard—my sinuses start hurting and my lungs get so full of phlegm. But these are a total game-changer. As soon as I feel that first sign of getting sick, I take them and it fights everything off before it even starts. I’ve reached a point where I don’t even need paracetamol anymore because this works so much better as a natural alternative. If you deal with winter sinus pain or chest congestion, you need this in your cabinet.

Quick Defense is my holy grail sick product!!

This should be in everyones cabinet! Gaia brand has a wonderful line of quality products, and quick defense is my go-to for defense when I'm sick. It helps to speed up the process and immunity boost when sick or feeling like I'm about to get sick due to the elderberry and echinacea.

מצוין!

I’m really impressed with this product! The quality is excellent — you can tell right away from the texture and how well it works. It’s easy to use, feels natural, and delivers noticeable results. Shipping was fast and everything was well-packaged, as always with iHerb. Definitely a great purchase — I’ll be reordering for sure!
