i just received this in my last order and have not tried it yet. hopefully i wouldn't have to for a long time but i do hope it works whenever we need it.

Good for immunity system ... used it in flu and it helped.. the effects was a relief . the ingredients are good... The size is okay.. Zinc supplements are most effective if they are taken at least 1 hour before or 2 hours after meals. However, if zinc supplements cause stomach upset, they may be taken with a meal. You should tell your health care professional if you are taking your zinc supplement with meals.

This is the best homeopathy medicine i ever tried, i use it for myself hubby and my 5 years old daughter. I’m not sure how many bottles I’ve ordered from it, highly recommended!!!

Taste is not bad. The only bad thing is it takes awhile to dissolve but being that the taste isnt awful, its not that big of a deal. Helps relieve flu symptoms

Helped me recover from a serious cold. I noticed an improvement within 24 hours of starting to take ReBoost.

Nice to have this handy especially at this time during the pandemic.

An excellent anti-flu remedy, helped me a lot, highly recommend

This is an excellent product to have on hand during fall, winter,and spring!

I take two when I first feel the flu and I feel better the day after, I like it

Good quality & ingredient, benefit to hair and antioxidant, taste, size & package are reasonable
