Using this tonic for the past 1 year but didn’t feel like something unsafe.
However,
It is advised to don’t use this tonic with something that has the same ingredient as nagano tonic.
Just keep this in mind and you are ready to go.
Rest assured,
I can definitely say this that nagano tonic is 100% safe to use for any age group or gender.
But if you are someone who is allergic to the ingredients that nagano tonic has, you better be not taking it.
There are lots of alternatives for this drink like Berbacil.
You can use that also that has the same effect as nagano tonic have.
