My children occasionally need a really good nights rest.
Sometimes my kids need a good night's rest and this is my go-to product for that! The raspberry flavor makes it easy for them to take as well.

Didn't Notice Difference
The taste is actually pretty good, honestly it's more like a treat than a supplement... but I haven't noticed any significant changes after going through the entire bottle. They didn't cause any upset stomach or side effects, which is a plus, but the overall benefits feel negligible.

GREAT CONCEPT AND DESIGN
I bought these Feminine Balance Gummies because I was intrigued by the approach that was utilized. For me, I have been involved with lactobacillus formulas and probiotics with incorporating yogurt (the really healthy kind not the ones with a lot of advertising) to deal with yeast overgrowth. Typically I am experiencing a problem because I am consuming too much sugary foods (causing the body's resources to be depleted) or because I have taken a course of antibotics which killed both the good and bad bacteria in the body and now needs replenished. So, my first impression was the intrigued by the use of Pineapple as a part of the formulation, which is unusual but a good choice nonetheless because it is very beneficial for digestion and also for pain reduction. I liked the taste of the gummy, it tasted like Pineapple candy. The inclusion of Vitamin C seemed a bit of a stretch and is included to enhance the immune function. There are lactobacillus strains but the manufacturer has kept the strains used as a proprietary secret - which I find a bit frustrating as a consumer. Whatever it is, there is a billion of them (is this per gummie?). The manufacturer does support the use of vegan only products, it is also "clean" Halal, it is gluten free and allergen free. So, it appears they have carefully considered the inclusion of each ingredient for benefit. So here is the real test, yes, I have had the desired outcome by improving my "lady garden" and this is a very viable product in my opinion. I would recommend it to others.
