So far, so good!

I've been taking this for a while and I feel like it has kept me healthy. I work at a school and I have avoided the cold that seemed to plague most of the school!
I am taking this in part (and in conjunction with other things) to try and help some covid long-haulers issues. For this, I think it's too early to tell, but so far-so good!
It has a VERY bitter taste-that I was able to adjust to. I just take it with water.

Nothing Like It!

If I could only have one product to maintain my health, it would easily be Advantage. I’ve been using it for years and it’s gotten me through some amazingly difficult health crises! I never want to be without it!

I have the Advantage!

I have been the only one who has not gotten sick this winter! I use 15 drops twice a day in my flavored water.

Very Pleased!

Ordered this for a friend and she just loves it. Easy to use, effective, and 1 bottle lasts a long time. Nutrikey gives fast service, too. :)

Definitely a Winner

My twin sister swore by this product, ALC, and said she hadn't been sick since she started taking it. I finally started but did not see any results until I started taking 3 droppers twice a day and can honestly say that I have not been sick since then. I dilute it into my Metamucil in the morning and in half bottle of caffeine free soda at night, I have not run out since then, I always make sure I have it on hand. I agree with my sister, this works great!! Nutrikey ships rapidly and efficiently. I love to order it here.
