Vitamin C is essential to our overall good health; however, it is water-soluble so any Vitamin C not used by the body is readily eliminated. That means that this important vitamin needs to be replenished daily. Vitamin C is crucial because it is known to play multiple supporting roles in keeping people feeling their best.

For example, Vitamin C acts as an antioxidant, which may help to protect the body’s cells from potential oxidative damage of reactive oxygen species (ROS) and free radicals. In addition, Vitamin C may help support immune system function. With the challenges of daily living, maintaining immune function through exercise, proper nutrition, and the right amount of sleep is one of the best things you can do for your body.

Moreover, Vitamin C is considered one of the key building blocks in the body. For instance, Vitamin C is required for the synthesis of collagen, as well as other substances in the body. In turn, collagen may support connective tissue health, and that includes the health of gums, teeth, and bones. So, Vitamin C, directly and indirectly, may support many areas of good health in the body.

Kirkland Vitamin C Reviews

Read reviews from people who have taken Kirkland Vitamin C and discover how they have benefitted from this supplement.

“GREAT Vitamin C. This vitamin C is incredibly effective…much more effective than any other Vitamin C I have taken. And I’ve tried lots of brands. My mother and I each take one tablet per day (1000mg). My mother has a long history of recurrent urinary tract infections, and this vitamin C has virtually eradicated that issue. She has not had even one UTI since she began using this vitamin C.

For me, it has boosted my immune system (haven’t had even a hint of a cold) and makes the skin on my face firm and radiant. I don’t know why this vitamin C is so much more effective than others, but it is. It simply works. I can highly recommend this product.”

“Best vitamins siya. Eto pinapainom ko sa brother ko kasi sumasakit gout nya. Infairness hanggang ngayon di na sumasakit kahit kumain siya ng mga bawal. Pero syempre pag naubos na yung isang bottle papahinga muna ng 1-week para macleanse man lang.” – Sofia

“Couldn’t be more satisfied. The exact same product I’ve been buying for many years now. Arrived in perfect condition and in a most timely manner. Though to some, the tablets might be a bit large, they are easy to swallow (I have mine with morning coffee or a late-night tea). Value? I’ve never known how Kirkland does it but the quality meets the higher-priced vitamins at a most exceptional price.

I’ve seen reviews discussing the “flavor” and don’t understand them. The tablets are swallowed easily enough, they’re not “chewable“, so the flavor has nothing to do with the potency or flavor, to my thinking. They “taste” the same as any other tablet of the same or similar. If “flavor” is an issue, I recommend buying chewable or mix-with-water powders.

For health reasons and professional advice, I’ve been taking these at least once every day for many years and am pleased with the quality and particularly with the value. This will be my “Go-To” from now on.” – Judah

“The capsule-shaped tablets are big and rather difficult to swallow. Chewing them up is horrible!” – Tina

“For many years I’ve depended on Kirkland Vitamin C and wouldn’t be without it in the house. And in recent times, it’s not only just a “precaution” or a mere “supplement”, it’s actually an “essential” to my well-being so it’s a necessity. That said, the quality is the same as the very much more costly “health brands” and they’re just as easy to swallow as the “special coated” tablets.

The price is amazingly competitive and, as I say because they’re a necessity in this household, that’s appreciated more than I can express. I’m grateful for them and will Kirkland will always be my first “go-to” brand… not only for this product but for many others. Amazing quality.”
– Jude

“My family and I love it. Okay naman siya for us so far, and nahiyang naman kami. So far, great value for the price. And during this pandemic, super essential uminom ng Vitamin C to boost immunity, so taking Kirkland Vitamin C has been indispensable to us.” – ML
