Vitamin C 1000 100 capsules by Nutri-Dyn
Nutri-Dyn

Vitamin C 1000 by NutriDyn is a potent vitamin C supplement that provides powerful antioxidant and immune system support. It contains pure ascorbic acid to help combat oxidative stress. Vitamin C is one of the body's most important antioxidants. It's involved in optimal immune function, neurotransmitter production (including norepinephrine and dopamine), and healthy liver function. It also plays important roles in iron absorption and the production of collagen needed for healthy skin, hair, bones, joints, and blood vessels. Vitamin C acts to recycle other important antioxidants including glutathione and vitamin E. It can be challenging to meet the daily requirement for vitamin C through diet alone. Because it's a water-soluble vitamin, our bodies aren't able to store large quantities like fat-soluble vitamins so we must consistently take in vitamin C to meet our bodies' needs. During times of stress, our bodies' need for vitamin C is greatly increased and supplementation may be required. This important micronutrient is able to help with stress in many different ways. Foremost, it's able to improve poor immune function caused by stress. It can help reduce levels of the stress hormone cortisol and help control oxidative stress. Vitamin C is also helpful for when you're feeling a little under the weather. While it may not be able to prevent you getting sick with a cold, vitamin C can help you recover faster by boosting your immunity to help you fight the illness better. Research has found NurtiDyn's Vitamin C 1000 may be helpful for: Improving immune function. Supporting collagen synthesis. Protect against oxidative stress. Recover from colds faster.

Vitamin C-400 180 tabs by Innate Response
Innate Response

Gentle and effective. 400 mg FoodState vitamin C can be taken anytime of day, even on an empty stomach. Phenolic blend of orange, wild blueberry and cranberry. Vitamin C is a water-soluble vitamin needed for the growth and repair of tissues in all parts of the body. It is necessary to form collagen, an important protein used to make skin, scar tissue, tendons, ligaments, and blood vessels. Vitamin C is one of many antioxidants. Antioxidants are nutrients that block some of the damage caused by free radicals, which are by-products that result when our bodies transform food into energy. The build- up of these by-products over time is largely responsible for the aging process and can contribute to the development of various health conditions such as cancer, heart disease, and a host of inflammatory conditions like arthritis. Antioxidants also help reduce the damage to the body caused by toxic chemicals and pollutants such as cigarette smoke. Vitamin C deficiency can lead to dry and splitting hair; gingivitis and bleeding gums; rough, dry, scaly skin; decreased wound-healing rate, easy bruising; nosebleeds; weakened enamel of the teeth; swollen and painful joints; anemia; decreased ability to ward off infection; and, possibly, weight gain because of slowed metabolic rate and energy expenditure. The body does not manufacture vitamin C on its own, nor does it store it. It is therefore important to include plenty of vitamin C-containing foods in one’s daily diet.

About Vitamin C

Vitamin C is necessary for human growth and development. However, unlike other animals, people must get their vitamin C from food and other sources as the human body does not produce it naturally. Good food sources of vitamin C include fruits and vegetables, especially citrus fruits. Vitamin C can also be produced synthetically in a laboratory.

The most common use of vitamin C is to reduce the risk of the common cold and reduce its severity if you do catch it. In addition, it is used for other infections such as gum disease, acne, skin infections, bronchitis, bladder, prostate, and stomach ulcers caused by bacteria. Vitamin C has also been known to help with depression, dementia, Alzheimer's disease, reducing physical and mental stress, fighting fatigue, and reducing the symptoms of attention deficit hyperactivity disorder.

Some people also believe that taking vitamin C can help improve heart and blood vessel health. The skin can even benefit from vitamin C as it is known to help protect against the sun, pollutants, and environmental hazards. Vitamin C can also be applied directly to the skin to help reduce the damage from radiation therapy.
