Do you know the ingredients of Ocuvite supplement? Are the ingredients in Ocuvite safe for consumption?
Dietary supplements are products designed to augment your daily intake of nutrients, including vitamins and minerals. Normally, you should be able to get all the nutrients you need from a balanced diet. However, supplements can provide you with extra nutrients when your diet is lacking or certain health conditions trigger a deficiency.
While most dietary supplements are safe as long as you follow the product instructions, large doses of a certain ingredient can have adverse effects. Also, some may not contain the ingredients that they claim to have.
So understanding what ingredients Ocuvite supplement contain is the most critical step before making a purchase.
Over the past few weeks, I have done thorough research about the ingredients of Ocuvite supplement. So I can tell you whether it’s safe to consume Ocuvite supplement.
I’m going to cover the benefits and potential side effects of the Ocuvite ingredients in this article.
What are the Ocuvite Ingredients?
Before we talk about the benefits and side effects of the Ocuvite Ingredients, let me give you a brief overview of the ingredients used in Ocuvite supplement.
Ocuvite supplement contains the following ingredients:
- Vitamin C
- Vitamin E
Lutein is part of the carotenoid family of antioxidants. Carotenoids are a type of phytonutrient, or plant chemical, found in the cells of many types of plants.
Carotenoids are responsible for the vibrant colors seen in many plants, such as the bright red, orange, and yellow hues of various fruits and vegetables.
While these pigments play an important role in plant health, they also provide health benefits for people who eat foods that are a good source of this phytonutrient.
Along with lutein, zeaxanthin is another important carotenoid that offers eye health benefits. It’s structurally similar to lutein, with just a small difference in the arrangement of its atoms.
Lutein and zeaxanthin are the only dietary carotenoids found in your retina. They’re concentrated mostly in the macula region, located at the back of your eye, which is essential for your vision. Because of where they’re concentrated, these two carotenoids are known as macular pigments.
Zeaxanthin is a carotenoid found in the human eye. The other two carotenoids your eyes contain are lutein and meso-zeaxanthin
Meso-zeaxanthin is thought to be created when your body breaks down other carotenoids, and you don’t typically get it from your diet.
Carotenoids are fat-soluble, antioxidant molecules that are bright red, yellow, or orange. They’re found in some algae, bacteria, fungi, plants, fruits, and vegetables.
They’re essential nutrients that you have to get from your diet.
Of the 700 carotenoids identified in nature, only about 20 have been consistently found in the human body. Of these, zeaxanthin and lutein are primarily found in the human eye.
You can find zeaxanthin and lutein in a variety of fruits, vegetables, and animal products, such as egg yolks.
They belong to the carotenoid class of pigments called xanthophylls, and they’re found in high concentrations in light-exposed structures in both plants and the human eye.
In scientific studies, zeaxanthin and lutein are often described together due to their overlapping functions in the eye, but also because the human body can convert lutein into zeaxanthin.
Zeaxanthin is concentrated in the center of the retina, while lutein is found in the peripheral regions of the retina. Together, they form the macular pigment of the eye.
Both offer antioxidant benefits, although zeaxanthin is the more effective antioxidant.
In humans, the most studied functions of carotenoids — including zeaxanthin — are vision and their role in eye health and the reduced risk of eye disease.
Omega-3 fatty acids are a type of polyunsaturated fat — also referred to as “healthy fats” — praised for their potential protective roles in several chronic diseases, such as heart disease and dementia.
They are one of the key building blocks for cell membranes and remain a subject of interest in the scientific community.
The family of omega-3 fatty acids includes:
- alpha-linolenic acid (ALA)
- stearidonic acid (SDA)
- eicosapentaenoic acid (EPA)
- docosapentaenoic acid (DPA)
- docosahexaenoic acid (DHA)
DHA and EPA are the primary polyunsaturated fats in brain cell membranes and have been popularized and successfully marketed as dietary supplements.
Omega-3 fatty acids are essential, meaning the human body is incapable of creating them on its own — the fatty acids or their precursors must be obtained from the diet.
For instance, ALA from plant seeds can be converted in the body to all the other types of omega-3 fats: EPA, SDA, DHA, DPA.
Zinc is considered an essential nutrient, meaning that your body can’t produce or store it.
For this reason, you must get a constant supply through your diet.
Zinc is required for numerous processes in your body, including:
- Gene expression
- Enzymatic reactions
- Immune function
- Protein synthesis
- DNA synthesis
- Wound healing
- Growth and development
Zinc is naturally found in a wide variety of both plant and animal foods.
Foods that don’t naturally contain this mineral, such as breakfast cereals, snack bars and baking flour, are often fortified with synthetic forms of zinc.
You can also take zinc supplements or multi-nutrient supplements that provide zinc.
Because of its role in immune function, zinc is likewise added to some nasal sprays, lozenges and other natural cold treatments.
Copper is an essential trace mineral necessary for survival. It is found in all body tissues and plays a role in making red blood cells and maintaining nerve cells and the immune system.
It also helps the body form collagen and absorb iron, and plays a role in energy production.
Most copper in the body is found in the liver, brain, heart, kidneys, and skeletal muscle.
Both too much and too little copper can affect how the brain works. Impairments have been linked to Menkes, Wilson’s, and Alzheimer’s disease
Deficiency is rare, but it can lead to cardiovascular disease and other problems.
Vitamin C is an essential vitamin, meaning your body can’t produce it. Yet, it has many roles and has been linked to impressive health benefits.
It’s water-soluble and found in many fruits and vegetables, including oranges, strawberries, kiwi fruit, bell peppers, broccoli, kale, and spinach.
The recommended daily intake for vitamin C is 75 mg for women and 90 mg for men.
While it’s commonly advised to get your vitamin C intake from foods, many people turn to supplements to meet their needs.
Though vitamin E is often thought of as a single compound, it’s actually a group of eight fat-soluble compounds with powerful antioxidant effects.
Of these eight chemical forms, alpha-tocopherol best meets the dietary requirements of humans.
Vitamin E exists naturally in certain foods, including seeds, nuts, some vegetables, and some fortified products. You can also take it as a dietary supplement.
It plays many roles in your body. It’s perhaps best known for its antioxidant effects, protecting your cells from oxidative damage by neutralizing harmful molecules called free radicals. In addition, it’s needed for proper immune function and cellular signaling.
That’s why it’s not surprising that research suggests taking vitamin E supplements may benefit your health in several ways.
Benefits of Ocuvite Ingredients
The ingredients in Ocuvite supplement are carefully sourced and formulated. There are many benefits to your health.
1. Support eye health
Ocuvite contains lutein. As powerful antioxidants, lutein may protect your body and especially your eyes in numerous ways. With regards to your eye health, research suggests that these nutrients may help:
- suppress inflammation
- defend against free radicals and oxidative stress
- enhance the sharpness of your vision
- improve your visual contrast sensitivity
- reduce glare impairment
- protect eye tissue from sunlight damage
- reduce cell loss and death related to eye disease
- protect your eyes from harmful blue light
- convert light signals into electrical signals in your retina and aid in the transmission of those signals to the visual cortex in your brain
- protect against nearsightedness (myopia) and protect pre-term infants against the effects of retinopathy of prematurity (ROP)
2. Reduced risk of eye disease
Ocuvite contains zeaxanthin. Many studies demonstrate that zeaxanthin plays an important role in eye health throughout the lifespan. In particular, it’s associated with a lower risk of age-related eye disease, including AMD, cataracts, and glaucoma.
These eye conditions lead to the destruction of the macula of the eye — the region responsible for fine-feature vision. The macula is also where the carotenoids zeaxanthin and lutein are stored.
Cataracts, glaucoma, and diabetic retinopathy are all eye conditions caused by damage to the nerves in the eyes due to prolonged high blood sugar levels, which can happen to people with diabetes.
AMD is the leading cause of blindness in people over the age of 40 in the United States.
Zeaxanthin’s antioxidant properties help prevent oxidative stress, reduce inflammation in the eye, and protect the macula from damage.
Zeaxanthin also plays an important role in eye development in developing fetuses, as well as in optimal vision during young adulthood.
A diet rich in zeaxanthin and other antioxidants may increase the density of the macular pigment and is associated with a lower risk of eye disease.
3. May improve brain health and cognition
Ocuvite contains zeaxanthin. In addition to its role in vision, zeaxanthin is present in regions of your brain associated with cognition, movement coordination, and decision making.
Less research has been conducted on the benefits of zeaxanthin for the brain compared with its benefits for the eyes.
Nonetheless, studies have shown that people with Alzheimer’s who have higher levels of zeaxanthin have a lower mortality rate from the disease.
Other studies suggest that taking 2 mg of zeaxanthin daily may not improve cognitive function in people with Alzheimer’s disease.
It’s unclear how this finding relates to the dietary intake of zeaxanthin from foods. Researchers estimate that the average daily intake of zeaxanthin in the United States is 1.3 mg, but that it may reach as high as 25 mg in some South Pacific populations.
4. Can Reduce Symptoms of Metabolic Syndrome
Metabolic syndrome is a collection of conditions.
It includes central obesity — also known as belly fat — as well as high blood pressure, insulin resistance, high triglycerides and low “good” HDL cholesterol levels.
It is a major public health concern because it increases your risk of many other illnesses, including heart disease and diabetes.
Ocuvite contains Omega 3. Omega-3 fatty acids can improve insulin resistance, inflammation and heart disease risk factors in people with metabolic syndrome.
5. Boosts Your Immune System
Ocuvite contains Zinc. Zinc helps keep your immune system strong.
Because it is necessary for immune cell function and cell signaling, a deficiency can lead to a weakened immune response.
Zinc supplements stimulate particular immune cells and reduce oxidative stress.
For example, a review of seven studies demonstrated that 80–92 mg per day of zinc may reduce the length of the common cold by up to 33%.
What’s more, zinc supplements significantly reduce the risk of infections and promote immune response in older adults.
6. Decreases Inflammation
Ocuvite supplement contains Zinc. Zinc decreases oxidative stress and reduces levels of certain inflammatory proteins in your body.
Oxidative stress leads to chronic inflammation, a contributing factor in a wide array of chronic illnesses, such as heart disease, cancer and mental decline.
In a study in 40 older adults, those who took 45 mg of zinc per day experienced greater reductions in inflammatory markers than a placebo group.
7. May Reduce the Risk of Certain Age-Related Diseases
Ocuvite contains Zinc. Zinc may significantly reduce your risk of age-related diseases, such as pneumonia, infection and age-related macular degeneration (AMD).
Zinc may relieve oxidative stress and improve immune response by boosting the activity of T-cells and natural killer cells, which help protect your body from infection.
Older adults who supplement with zinc experience improved influenza vaccination response, reduced risk of pneumonia and boosted mental performance.
In fact, one study determined that 45 mg per day of elemental zinc may decrease the incidence of infection in older adults by nearly 66%.
Additionally, in a large study in over 4,200 people, taking daily antioxidant supplements — vitamin E, vitamin C and beta-carotene — plus 80 mg of zinc decreased vision loss and significantly reduced the risk of advanced AMD.
8. May lower your risk of heart disease
Heart disease is the leading cause of death worldwide.
Many factors increase the risk of heart disease, including high blood pressure, high triglyceride or LDL (bad) cholesterol levels, and low levels of HDL (good) cholesterol.
Ocuvite supplement contains Vitamin C. Vitamin C may help reduce these risk factors, which may reduce heart disease risk.
For example, an analysis of 9 studies with a combined 293,172 participants found that after 10 years, people who took at least 700 mg of vitamin C daily had a 25% lower risk of heart disease than those who did not take a vitamin C supplement.
Interestingly, another analysis of 15 studies found that consuming vitamin C from foods — not supplements — was linked to a lower risk of heart disease.
However, scientists were unsure whether people who consumed vitamin-C-rich foods also followed a healthier lifestyle than people who took a supplement. Thus, it remains unclear whether the differences were due to vitamin C or other aspects of their diet.
Another analysis of 13 studies looked at the effects of taking at least 500 mg of vitamin C daily on risk factors for heart disease, such as blood cholesterol and triglyceride levels.
The analysis found that taking a vitamin C supplement significantly reduced LDL (bad) cholesterol by approximately 7.9 mg/dL and blood triglycerides by 20.1 mg/dL.
In short, it seems that taking or consuming at least 500 mg of vitamin C daily may reduce the risk of heart disease.
9. May reduce markers of oxidative stress and improve antioxidant defenses
Oxidative stress is a condition that occurs when there’s an imbalance between your body’s antioxidant defenses and the production and accumulation of compounds called reactive oxygen species (ROS). This can lead to cellular damage and increased disease risk.
Ocuvite contains vitamin E. Because vitamin E acts as a powerful antioxidant in the body, studies have shown that supplementing with high doses of it can reduce markers of oxidative stress and boost antioxidant defenses in some populations.
For example, a 2018 study in 54 people with diabetic nephropathy — kidney damage caused by high blood sugar — found that supplementing with 800 IU of vitamin E per day for 12 weeks significantly increased levels of glutathione peroxidase (GPx) compared with a placebo.
GPx is a group of antioxidant enzymes that protect your cells from oxidative damage.
A 2021 study also showed that supplementing with a combination of vitamin E and vitamin C daily for 8 weeks reduced markers of oxidative stress, such as malondialdehyde and ROS, in women with endometriosis.
Side Effects of Ocuvite Ingredients
When taken at the recommended doses, the ingredients in Ocuvite supplement are generally safe to consume. However, you should bear in mind that some may cause side effects when used improperly.
For example, Ocuvite contains Zinc. Zinc is likely safe when used in amounts no greater than 40 mg daily. However, taking very high doses of zinc is likely unsafe and might cause stomach pain, vomiting, and many other problems.
Final Verdict: Are Ocuvite Ingredients Safe or Harmful?
To conclude, the ingredients used in Ocuvite supplement are generally safe for adults. They are natural ingredients that do not usually have any side effects, but it should not be used by kids or women who are pregnant or breastfeeding. All you need to do is follow the dosage instructions.
However, while there have been no reported side effects of Ocuvite supplements in most healthy adults, you might still consult your doctor for double confirmation.
