Protects Memory
Dementia is a catch-all phrase for symptoms associated with poor memory and thinking. It affects over 35 million individuals worldwide and is especially common among those above the age of 65. Vitamin C is a potent antioxidant. Low levels of this vitamin have been linked to decreased cognitive function. Vitamin C helps to fight free radicals, the particles that damage cells within the brain. Free radical damage is involved in conditions like Alzheimer’s disease and dementia because it makes communication between neurons harder or impossible for them due to oxidative stress.
Boosts Immunity
Vitamin C is involved in many aspects of the immune system, which is one of the reasons people take vitamin C supplements. Vitamin C is necessary to produce white blood cells, which fight bacterial and viral infections. It helps the immune system by preventing oxidative stress damage that reduces activity or kills off significant immune cell populations (such as T-cells). People with vitamin C deficiency symptoms often complain of frequent colds and flu because these conditions start due to lowered immunity from chronic infection.
Improves Skin Health
Vitamin C not only protects your skin from free radicals but also plays a vital role in collagen production within your body’s connective tissues like bones and muscles. Collagen keeps skin looking young and vibrant over time if you get plenty of this essential nutrient each day through diet alone (or supplements when needed). Many people find their wrinkles fade away after consuming plenty of vitamin C from oranges, grapefruit, and other healthy foods.
Improves Vision
Vitamin C deficiency symptoms include eye problems like blurred vision, dry eyes, and difficulty seeing colors. Vitamin C helps make sure your cornea remains healthy by maintaining the lipid (oil) balance. This will prevent damage caused by oxidative stress that leads to conditions like cataracts or other degenerative issues with the corneas of your eyes over time.
Helps Maintain Healthy Hair And Nails
People who don’t get enough vitamin C often suffer from hair loss because this nutrient works together with iron for red blood cells (and hemoglobin) to be produced efficiently inside bone marrow tissue found throughout our tresses on top of heads everywhere! Vitamin C also assists protein formation within tissues, so nails grow strong alongside shiny and healthy hair.
Prevents Cancer
Oxidative stress damages DNA and other cellular structures over time, which increases the risk of cancerous cell development inside your body because it makes cells divide uncontrollably. Vitamin C helps prevent oxidative damage thanks to its antioxidant properties, so you don’t have a higher chance of developing certain cancers (like prostate or breast). Some studies even show that vitamin C intake from foods like oranges reduces your chances by up to 50%!
How Much Vitamin C Do You Need?
The RDA for vitamin C for adults is 65 to 90 mg per day, with a daily upper limit of 2,000 mg. However, megadoses of vitamin C supplements might cause diarrhea. The NIH states that the daily recommended intake of vitamin C is as follows:
- Ages 0 – 6 months: 40 mg
- Ages 7 – 12 months: 50 mg
- Ages 1 – 3 years: 15 mg
- Ages 4 – 8 years: 25 mg
- Ages 9 – 13 years: 45 mg
- Ages 14 – 18 years: 75 mg
- Ages 19+ years: 90 mg
Vitamin C is important for pregnant women, who require approximately 75 mg per day. Vitamin C supplementation is beneficial for smokers who need 35 mg extra each day than nonsmokers.
Sources Of Vitamin C
Fresh fruits and vegetables are the best sources of vitamin C, including citrus fruit like oranges, grapefruit, lemons, limes, melons. Broccoli is a good source of this nutrient as well. Because ascorbic acid is water-soluble and is destroyed by heat, the vitamin C content of food may be reduced over time. Cooking or peeling fruit and vegetables will reduce the vitamin C content. Fortified breakfast cereals are also good sources, as well as fortified juices like orange juice.
Vitamin C Deficiency
If you don’t get enough vitamin C from your diet, symptoms such as fatigue and lethargy may result. Other signs of a deficiency include bleeding gums or nosebleeds, bruising easily, hair loss, easy weight loss (despite poor dietary choices), and frequent infections due to low immunity levels.
Health Risks From Too Much Vitamin C
Vitamin C has low toxicity and isn’t thought to cause serious adverse effects in large doses. The most frequent complaints are diarrhea, nausea, abdominal cramps, and other gastrointestinal problems due to the osmotic effect of unabsorbed vitamin C in the stomach. High intakes of vitamin C have also been linked to reduced levels of vitamin B12 and copper, accelerated metabolism or excretion of ascorbic acid, enamel erosion, and allergic reactions.
However, many of these findings were due to assay error, and additional research has not confirmed them. The FNB has set safety standards for vitamin C that apply to both food and supplement use. Long-term intakes of vitamin C above the UL may cause health problems. The ULs do not apply to persons receiving vitamin C for medical purposes, but they should be under a doctor’s care.
Conclusion
As you can see, vitamin C is an essential component of a healthy diet. Vitamin C is a water-soluble vitamin that serves many purposes in the human body. It aids in the healing of wounds, the formation of collagen, and immune function. It has a lot of advantages, but there are also drawbacks to consider. Make sure not to exceed the daily recommended intake without speaking with a doctor.
