    product feels like a tablet instead of a lozenge

    Its difficult to rate a product that is prophylactic in nature? While I generally use probiotics for my gut I was unfamiliar with the good bacteria for my mouth and throat. I have since read about the active ingredient and that it is good for oral health and against bas breath. this seems like a better marketing angle than against a sore throat, unless you are marketing to the hypochondriac population. Tha vanilla flavour is pretty terrible. and the tablet takes a bit too long to dissolve. It also leaves a sense of a coating on your teeth and when combined with the terrible vanilla flavour made me want to brush my teeth straight away or drink something, both of which decrease any benefit of the probiotics. I would opt for a light citrus, currant or berry flavour. I would also include a paper or electronic link describing the benefits of oral probiotics and links to studies on their benefits. Otherwise, like myself, most people might see this as another sham product sold at the chemist with dubious value and little medical oversight. Although it does play on peoples fears of illness and if you are marketing to the worried well then it is hitting its mark. Its a decent concept you have, but there are several flaws with the delivery.

    Blis Probiotics Throat Guard is not the easiest or convenient product to consume.

  4. Hubert

    Its a bit tasteless, maybe put some flavours to it.

  5. Sarah

    I chose Throat Guard Boosted Protection. They were chalky and slightly vanilla flavoured. The chalky texture was difficult to suck. It is hard to say if they were effective. I did not have a sore throat while taking them but continued to have mouth ulcers.

    throat guard lozenges

  7. Jaqueline

    not the most pleasant “lozenge” buy seemed to do something. i started using this when i actually had a sore throat and i definitely feel as though it healed faster than it normally would

  8. Rita

    It is better if it comes with other flavors.

  9. olivia

    I picked throatguard protect. I was good, I noticed quite a difference. legit my sore throat went within 2 days. however I cannot get past the taste and texture. its kind of like having to slowly chew sweetened chalk (very unpleasant)

  10. Thatiana

    Weird taste, but something that anyone can get used to it. No biggies. I haven’t had enough time since I bought it, but I can feel on my body some strength and cough reduced. I think it’s a great product. thanks for introducing it to me.

  11. Yvonne

    Throatguard Boosted protection Pleasant to taste. Easy to consume. No noticeable side effects.Good small size. My throat felt better the next day but not sure whether due to the first tablet or because the issue self resolved. I took after having a sore throat for about 6 days along with some cold symptoms

  12. Samantha

  15. John

    I picked the throatguard and it was more than I had expected. this product was effective and after taking it, the irritation and itchiness in the throat was gone. the taste was also nice and did not taste like medication which is what I expected.

    Blis Throatguard Boosted Protection Lozenges

  20. Jenessa

    I didnt like the taste at the start, prefer the taste of honey bliss over the vanilla flavour on their probiotic range. but the taste quickly caught onto me. its a good way to strengthen immunity as we head into autumn/winter.

  21. Jacqui

    What a pleasant surprise it was to taste the vanilla flavour of the Throatguard Probiotic Lozenges with boosted protection. Very easy to have every day.

  22. Cassy

    the taste isn’t the best but as a long time sufferer of tonsil stones and laryngitis this product has seemed to assist getting my throat back to normal

  23. Ayche

    the price on chemist warehouse online was 1/2 price but I paid full price in store

  24. audrey

    Tasted this product yesterday and the flavour is fantastic! Great job on the flavour/ taste. Has an itchy throat and by the end of the day I felt great!

  25. Ann

    I picked up the Blis Probiotic Throat Guard. Felt good knowing that healthy bacteria is going in me starting from the moment you put it in your mouth. Especially during this pandemic moment, having any healthy supplements to boost or defend your immune system is greatly appreciated. My only issue is that I found the tablets very chalky and dry once you pop it in the mouth while you are only allowed to suck on it only.

  26. Samantha

    I got the throat guard I have liked it so far and love the flavour as well. I think it will help with the throat protect it

  27. Fiona

    I got the immune defence lozenges. I really like them. it’s an easy task to take one immediately after brushing my teeth everyday. the lozenges itself is small, not at all chalky and tastes great!

  28. Stephanie

    BLIS PROBIOTICS THROAT GUARD has been a great way to balance the bacteria and promote throat health. The lozenges have a very light vanilla taste making then yummy and nice to have after brushing you’re teeth. They are convenient and easy to takes
