Preservision is a popular brand of eye health supplements that claims to help maintain healthy vision and protect against age-related macular degeneration (AMD). However, before deciding to include any supplement in your daily routine, it is crucial to understand if it meets the regulatory standards set by the Food and Drug Administration (FDA) in the United States.
FDA Regulations and Standards for Supplements
The FDA regulates dietary supplements under a different set of rules compared to prescription drugs. While prescription drugs require extensive testing and approval, dietary supplements like Preservision are regulated under the Dietary Supplement Health and Education Act (DSHEA) of 1994.
Under DSHEA, supplement manufacturers are responsible for ensuring product safety and labeling accuracy, and the FDA does not approve or review dietary supplements before they are marketed. However, the FDA can take action against any supplement if it poses a health risk or makes misleading claims.
Predominant Ingredients in Preservision
Preservision's formula consists of various ingredients known to support eye health. The key ingredients include:
1. Vitamin C:
Essential for the formation and maintenance of healthy blood vessels in the eye.
2. Vitamin E:
An antioxidant that protects the eye's cells from damage caused by free radicals.
3. Zinc:
Helps transport vitamin A to the retina, playing a vital role in maintaining healthy vision.
4. Copper:
Assists in the formation of connective tissues in the eye.
5. Lutein and Zeaxanthin:
Maintain the health of the macula, an area of the retina responsible for central vision.
6. Omega-3 Fatty Acids:
Support overall eye health and reduce the risk of developing AMD.
Evidence-Based Research and Clinical Trials
Preservision's ingredients have been extensively studied for their potential benefits in eye health. Numerous clinical trials and research studies have investigated the effects of these ingredients on AMD, cataracts, and overall visual acuity.
Several studies have shown that lutein, zeaxanthin, and antioxidants like vitamin C and E can help reduce the risk of AMD progression and improve visual function. Omega-3 fatty acids have also demonstrated positive effects on dry eye syndrome and other ocular conditions.
