I've only been taking them for a short while, and was pretty sceptical, but I have noticed a difference with digestion and even with rhinitis. I hope this will continue to work.

They seem to be working!

It's a little hard to definitely tell if these work, so far I seem to be having good results, definitely with no negative effects. I'm allergic to wheat, dairy and soy. So to start off with, they're safe/no reactions - as you would hope! - and they're nice and small, easy to swallow. I like that they have both probiotics and vitamin C, as then I'm covering all bases trying to ward off the winter bugs! I started taking them when my sinuses flared up. I'd been sick for a few days, I was quite distinctly better the next day, and by the day after I was fine. I then went overseas for a month, came back with another respiratory infection. This time pretty sick. Again, started taking them, seemed quite a lot better over the next couple of days, and by day 3 was well again - I'd had the bug over a week. Obviously, it's difficult to know what the course of the bugs would have been without these! But I definitely seemed to improve once I started taking them, and i wasn't showing any signs of improving before I did. So I would say they're worth a go? No negative effects at all, and quite possibly some very positive results!

convenient and easy to swallow

Have taken one a day for a month and as yet have been cough and cold free. Although easy to take, the price tag discourages me from introducing this product into my daily routine

No difference

I started taking these for a few days but didn’t notice any differences. On the plus side, the capsules are tasteless and easy to swallow but for the price, I’d rather buy some multivitamins that last three months.

Easy to swallow capsule

Obviously difficult to tell the immunity benefits but good to have probiotics combined with vitamin C. Same company I have used and been very satisfied with before and much smaller capsules which are easy to swallow.

Good all rounder

Been using for a couple of weeks and Ive managed to avoid the kids bugs so far! I also feel like I have a bit more energy (which is no mean feat with 3 children under 4!) Will be more than happy to continue using them
