NutriBiotic, DefensePlus
Verified purchase
I've been using this supplement to support my immune system. Overall, DefensePlus is a great addition to my daily health routine, and I highly recommend it to anyone looking to boost their immune support naturally! Taste is good but tablet is a bit larger making it difficult to swallow

DefensePlus
Verified purchase
Quality of the supplement is wonderful . Ingredient is very nice. The size is fine for me. The dosage is individual. Benefit was for me that I started feeling way better towards my stomach. No heaviness after meals. The taste is herbal. I started feeling much more comfortable in my nutrition routine.

Very strong!
Verified purchase
Beware it is very strong supplement! I had nausea from it when I took it and lasted couple of days. First day was very strong and afterwards couple of days still but more like medium. Recommend to try it on your free day in the morning after you have eaten. Don´t really have any test and it looks like a big pill. Love the ingredients and quality is also high. I used these for my candida diet but had to make a pause from these pills because too strong to take it on my workday.

It's working
Verified purchase
These DefensePlus tablets are my must-have during the autumn and winter season, especially when used together with their nasal spray. They help support overall wellness and immunity, offering protection against seasonal challenges.The size of the tablets is manageable to swallow. The quality is good - reliable, potent, and vegan-friendly. I can recommend this supplement for anyone looking to boost seasonal defenses and maintain wellness throughout the year to support immune function, reducing oxidative stress.

4 stars because...
Verified purchase
It is very good and strong. I am not ill, but I love to take them in case of not to become ill. I can give it only 4 stars because of the 'other ingredients' which could be better and less of them of course and because of its tablet form, though I prefer capsules.

The formula packs a combination of several immune-supporting ingredients: for example — grapefruit seed extract (GSE), vitamin C, zinc, herbal extracts (like astragalus, echinacea, Oregon-grape root, yarrow, ginger), and mushroom extracts (reishi, maitake, shiitake).
