Vitamin A and vision make potent allies. Carrots contain lots of beta carotene and Vitamin A, which can contribute to your eyes' health and may provide a fantastic source of eye vitamins for macular degeneration and cataracts. Good sources of Vitamin A and rhodopsin are also abundant in carrots.
Why Is Vitamin A Important For Eyesight? One of the most important benefits vitamin A has for our eyes is reducing the risk of macular degeneration and vision loss. It also boosts the immune system, helping soothe eye inflammation and decreasing our chance of developing eye infections.
Vitamin E. Together with vitamins A and C, vitamin E strengthens the tissues and cells in the body, including those in the eyes, which is why it is one of the best vitamins for blurry vision. This fat-soluble antioxidant also helps to prevent macular degeneration and cataracts.
Without enough vitamin A, your eyes cannot produce enough moisture to keep them properly lubricated. Vitamin A deficiency is the leading cause of preventable blindness in children worldwide. An estimated 250,000 to 500,000 children become blind every year because of vitamin A deficiency.
Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency. This happens when the deficiency causes damage to the optic nerve that leads to your eyes. The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.
"Taking some vitamin D is OK for an aging population," says Sporny, "but too much vitamin D can cause damage to blood vessels, eye tissue and kidneys."
Vitamin B12 supports and promotes eye health
Vitamin B12 can help maintain and promote healthy eyesight. As we get older, many of us suffer from macular degeneration (loss of eyesight). In a study on 5 000 women over the age of 40, sufficient vitamin B12 intake was linked to 34-41% lowered risk of macular degeneration.
Severe visual loss and legal blindness, which may be caused by the induced hyperexcitability and toxicity of the NMDA receptors, have been observed in Mg-deficient (Mg-D) patients (12).
The results showed that high doses of antioxidants vitamin C (500 mg), vitamin E (400 IU), and beta-carotene (15 mg/25,000 IU), along with zinc (8 mg), reduced the risk of vision loss from advanced age-related macular degeneration (AMD) in some, but not all, people with this disease.
People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their health care provider. Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
Magnesium assists in the activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. All of the enzymes that metabolize vitamin D seem to require magnesium, which acts as a cofactor in the enzymatic reactions in the liver and kidneys.
Caution is advised if you have diabetes, liver disease, phenylketonuria (PKU), or any other condition that requires you to limit/avoid these substances in your diet. Ask your doctor or pharmacist about using this product safely.
The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause nausea and vomiting, weakness, and frequent urination. Vitamin D toxicity might progress to bone pain and kidney problems, such as the formation of calcium stones.
Vitamin B12, or cobalamin, is naturally found in animal foods. It can also be added to foods or supplements. Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells.
B vitamins — like B6, B12, and folic acid — can help improve eye health by preventing age-related macular degeneration (AMD), a condition in which your retina deteriorates over time, causing blurry vision.
