How Does NSI® Vitamin C Work? Vitamin C, also known as ascorbic acid, is necessary for normal growth and maintenance of the human body. It plays a part in the development and repair of all bodily tissues and is crucial for healing wounds and repairing cartilage, bones and teeth. Vitamin C is also involved in the production of collagen, used to make skin, ligaments, tendons and blood vessels. Vitamin C is one of nature's most powerful antioxidants, working to protect the body from harmful free radical molecules. It's found in some concentration in fruits and vegetables, however citrus fruits, strawberries, cantaloupe, tomatoes, broccoli, potatoes and leafy greens are the best sources. As a water-soluble vitamin, vitamin C is not stored in the body and must be regularly replaced through diet or supplementation (the body cannot make it on its own). Deficiency is rare, but smoking, stress and certain illnesses can cause reduced levels. Supplementing with vitamin C may help strengthen the immune system. ¹. NSI® Vitamin C 1,000 mg is better because it:. Contains 1,000 mg Vitamin C per capsule. Is a better value when compared to other brands. ¹ Hemila H & associates. Vitamin C and the common cold: a retrospective analysis of Chalmer's review. Journal of the American College of Nutrition 1995: 14(2): 116-123. . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"In the past days, I usually took 3 pieces in the morning and another 3 pieces in the evening to take enough daily value which were sold in the shops in Japan. But with this product, I only take one capsule to take about the same value and it's comparatively cheaper considering shipping."

"while it is a little hard to decipher the direct outcomes of taking vitamin C (I take it 3 times a day) I would say it has made a difference and has helped me. More specifically, it has helped me recovered from constant high-intentity workouts. I workout 4-5 times a week either doing HIT (intensity to failure) bodybuilding routines or HIT strength routines (intensity to 1RM) doing dual factor training where I am most often than not in a state of fatigue. Taking a multi, vitamin C and fish oil 3 times a day in addition to good nutrition helps me recover faster than before. Cheers."

"My doctor suggested that I should take Vitamin C daily. I looked at many different sources but not very many places had it in capsule format. This is important to me because it is easier to take and works fastest.
Your prices were comparable and in some cases even less. It was easy to make this choice."

"A fresh product, unlike most store brands, providing a convenient 1,000 mg in just one capsule. When taking more than one supplement daily, as I do, having to take just one capsule daily does make a difference. Everybody should always have a bottle of this product at home."
