ACTIVE INGREDIENTS:

FERULIC ACID - Found in seeds, leaves and bark of plants, as a free acid or in ester form. It has antioxidant and anti-inflammatory properties, protecting components of the skin structure such as keratinocytes, fibroblasts, collagen and elastin.

VITAMIN C - Essential for several vital functions, it has an antioxidant action that protects skin cells against the effects of free radicals, such as those caused by exposure to solar radiation. Since it is not synthesized by the human body, it is necessary to obtain vitamin C from external sources, including topical application. Ascorbic acid is the only biologically active form of vitamin C, while other derivative forms are more stable and can be converted to ascorbic acid upon contact with the skin. Vitamin C stimulates the production of collagen and fibroblasts, acts in the formation of the skin barrier and reduces skin hyperpigmentation.

HOW TO USE:
» Use daily in the morning and evening
» Apply before creams, sunscreen and makeup
» Keep your face clean and dry
» Without touching the cannula to the skin, dispense a few drops onto your fingers or directly onto your face
» Gently spread over the face, including the eye area
» Avoid eye contact and sun exposure without adequate protection

High quality fiber
Size: 81 Count (Pack of 1)
Excellent fiber. I take it twice a day so it does fast but it's the best fiber gummy I've used in terms of results. Some of the flavors aren't my favorite but they're all palatable. I like the gummies because otherwise I forget to take them. It's hard to remember to take them exactly between other meds so having these sit out helps.

Works like a charm
Size: 81 Count (Pack of 1)
My gastroenterologist told me to take Benefiber, specifically, every day. I looked at a bunch of different kinds within the brand, and settled on this one because it seemed to have fewer ingredients I didn’t want. I was pleasantly surprised to find out they actually taste like candy my kids liked when they were younger. Yes, they are gummy and stick together a bit, just like any other gummy product, but I had no problems getting them out of their container nor eating them, unlike some reviewers. I keep them in a cupboard in a spot where it’s always an average temp. You can chew these or just let them dissolve in your mouth, something I do most often. I take them one by one after a meal, letting them slowly melt as I do other things before brushing my teeth. The best thing? They actually work. You should definitely start small and slowly increase to what is prescribed to you. It makes the process easier and more pleasant. My digestion seems to be better, and I no longer have constipation, just normal, average, healthy stool. They are an expense at the amount my doctor has me on, but they’re worth every penny to not have the awful pain and nausea I had before I started taking them. Highly recommend.

Good stuff, tastes nice, does the job
Size: 81 Count (Pack of 1)
Same as in the retail stores, only it's actually available through Amazon. When we head to the stores to pick it up locally, there's a 90% chance it's out.

Tastes great and works well!
Size: 81 Count (Pack of 1)
I've tried a number of different competing products in this space and found these to be the right combination of tastes good and works well. I do recommend! If they stick together in the container the probably got hot somewhere along the way to your house. Try freezing them and tapping the container ona counter. Should help break them apart.

It works!
This really solved a very obvious problem when one is on a Keto diet. It does the job gently-no side effects. This is a great product at a great price. Thank you.
