This bottle will last me well over 6 months, which is great for the price.
I recommend this to anyone who wants a vitamin C without upset stomach problems.
Good energy support supplement to pair with my daily vitamins.
I feel comfortable taking this regularly thanks to the non-acidic formula.
Easy to remember to take one a day since it’s not a large dose per capsule.
Capsules don’t stick together and the bottle was well packed when it arrived.
I appreciate that it’s formulated to be gentle but effective.
Quality seems to be consistent from bottle to bottle.
Great for daily use without the acid reflux issues I’ve had with other vitamin Cs.
No strong smell or taste, which makes it easy to take first thing in the morning.
A solid vitamin C product to have on hand, especially during cold season.
I’m not usually a fan of tablets but these capsules go down easily.
Nice that it comes in a big count so you’re not rushing to reorder every month.
Price per capsule is quite reasonable given the dose and formula.
Switched to this brand because of the bioflavonoids and I’m happy with the choice so far.
Packaging is good, bottle feels sturdy and seals well to keep capsules fresh.
Have noticed no negative effects, which is always a plus with any supplement.
This is a decent vitamin C option, especially for those looking for something less harsh on the digestive system.
The capsules are a bit larger than I expected but manageable.
I take these daily and they fit well into my routine, especially since they don’t upset my stomach.
Bottle size is generous and the capsules seem well made; no breakage or crumbling.
No weird fillers or taste – just a simple, straightforward product.
The addition of bioflavonoids makes me feel like I’m getting a more complete vitamin C source.
Good supplement if you want a steady amount of vitamin C without the acidity of regular ascorbic acid.
I have been using this for a couple of months and feel like it’s a good daily boost.
Capsules are easy to swallow and don’t leave a bad aftertaste like some vitamin C products.
Large bottle means I don’t have to reorder often, which is super convenient.
I like that it is non-acidic; I have a sensitive stomach and this doesn’t bother me at all.
Takes a bit to get used to swallowing so many capsules at once, but overall seems to be a quality supplement.
Great value for the price and lasts a long time. Easy on the stomach compared to other vitamin C supplements I’ve tried.
