Common questions about Preservision AREDS 2 (FAQ)
Q: What is the recommended age range for people taking Preservision AREDS 2?
The formula’s use is strictly defined by the clinical trial criteria, which focused on adults who are generally 50 years of age or older and who have been diagnosed with a specific stage of age-related macular degeneration (AMD). The use of this formula is not recommended for the pediatric population, which includes children and teenagers.
Q: Is this supplement meant to prevent eye conditions, or only slow their progression?
Clinical studies indicate the AREDS 2 formula helps to reduce the risk of progression to advanced age-related macular degeneration (AMD) in people who already have intermediate or advanced AMD in one eye. Clinical benefit has not been established for the purpose of preventing the condition in individuals with early or no AMD.
Q: Does Preservision AREDS 2 contain any ingredients derived from common allergens like shellfish or gluten?
Official product information states that certain forms of the supplement are labeled as free from common additives like gluten and soy derivatives. However, the presence of specific potential allergens may vary based on the exact product and formulation. Reviewing the complete ingredient list on the specific product packaging is recommended for full details.
Q: Can taking too much Preservision AREDS 2 be harmful?
Taking more than the recommended daily dose may increase the risk of documented serious adverse effects, primarily zinc-induced copper deficiency. It may also lead to consumers surpassing official safe upper intake levels for various components.
Q: Are there different concentrations or strengths of Preservision AREDS 2?
The AREDS 2 formula, based on the clinical study, uses a fixed concentration of active ingredients (Lutein, Zeaxanthin, Vitamins C and E, Zinc, and Copper) that is consistent across all PreserVision forms, including Caplets, MiniGels, and Chewables. While different forms are available, they are designed to deliver the same precise daily dose.
Q: Why are there different versions like 'Preservision AREDS 2 MiniGels'?
Different versions are available to address consumer needs related to specific absorption profiles or swallowing difficulty. For example, MiniGels are designed with an enhanced formulation for the absorption of Lutein and Zeaxanthin.
Q: How long does it usually take before a person notices any effects from taking Preservision AREDS 2?
The AREDS 2 formula is defined as a long-term chronic nutritional strategy aimed at protecting the integrity of ocular tissues over time. The clinical trial that established its benefit tracked progression over five years. As such, the effects are not expected to be immediately noticeable.
Q: Is the full benefit of Preservision AREDS 2 achieved after a certain number of months?
The formula is intended for consistent daily intake over a long period to maintain protective nutrient levels in the eye. The AREDS 2 study that established its benefit tracked participants over a duration of five years. Achieving the full protective benefit is generally tied to consistent, long-term use.
Q: Does the formula expire, and does potency decrease over time?
Official regulatory guidance requires that unused or expired medications and supplements be disposed of safely. The product packaging includes an expiration date which signifies the time period during which the formula is expected to remain at its full intended potency.
Q: Are the side effects generally mild, or are severe reactions common?
Official safety data classifies documented adverse reactions into two types: Common reactions, which are typically mild (like gastrointestinal upset), and Serious systemic reactions (like zinc-induced copper deficiency anemia). The risk of serious reactions is documented in regulatory texts but is generally considered rare compared to the common, milder effects.
Q: What should I do if I experience nausea after taking the capsules?
Nausea and stomach upset are classified as commonly documented side effects, generally associated with the high mineral content of the formula. If any side effects, including nausea, persist or are concerning, individuals should refer to the full safety information and regulatory guidance on adverse events.
Q: Does Preservision AREDS 2 contain Vitamin E, and is there a limit to how much Vitamin E is safe?
The formula contains a high dose of Vitamin E (400 IU daily). Regulatory documentation highlights the risk of interaction with certain medications, such as blood thinners, due to this high level. Consumers should be aware of official upper intake limits for Vitamin E when taking this supplement.
Q: Can it be taken alongside supplements like Omega-3 fish oil?
The AREDS2 clinical trial included a group that took Omega-3 fatty acids alongside the core AREDS 2 formula. The study found that adding Omega-3s did not demonstrate an overall beneficial effect on the progression of AMD in the participants.
Q: Has the AREDS 2 study been replicated by other research groups?
The efficacy of the AREDS 2 formula was established in the original five-year clinical trial sponsored by the NIH. The benefits have been reaffirmed by subsequent follow-up studies conducted by the National Eye Institute over a 10-year period.
Q: How does the dosage of Zinc in Preservision AREDS 2 compare to a typical daily zinc supplement?
The daily dose of 80 mg of Zinc in the PreserVision AREDS 2 formula is notably higher than the standard Recommended Dietary Allowance (RDA) for zinc, which is typically 8 mg to 11 mg per day for adults. This high concentration is part of the specific AREDS 2 protocol.
Q: Is there a different Preservision product available for people who are non-smokers?
The PreserVision AREDS 2 formula is beta-carotene free and is appropriate for all users, including non-smokers. However, the manufacturer also offers products with different component combinations, such as those that include a multivitamin or the original AREDS formula, though the latter is not recommended for smokers.
Q: Does the lutein in the formula come from marigolds or another source?
According to official product information and ingredient lists, the lutein and zeaxanthin in the PreserVision AREDS 2 formula are typically derived from marigold flower and/or paprika fruit extract.
Q: Do I need to inform my dentist that I am taking Preservision AREDS 2?
Official regulatory guidance highlights the importance of providing an up-to-date list of all medications and supplements to any healthcare professional, including dentists. This is because the high-dose components, such as Vitamin E, may pose interaction risks with certain medical treatments or procedures.
Q: Can this supplement change the results of my eye exam?
The components lutein and zeaxanthin structurally integrate into the eye and are known to increase macular pigment density. This density is sometimes measured during specialized eye exams; the supplement is designed to support the ocular tissue in patients undergoing regular eye examinations.
Q: Can taking this supplement affect liver enzyme levels?
Safety constraints note that caution is needed for individuals with pre-existing hepatic (liver) function impairment. However, no general effect on liver enzyme levels is listed as a common or serious adverse reaction in official product labeling.
Q: Are there any documented cases of overdose with Preservision AREDS 2?
Regulatory documentation contains information on the signs of overdose, which typically include severe stomach upset or vomiting. Additionally, overdose with products containing iron (found in some combination products) is highlighted as a serious risk.
Q: Does the FDA approve or regulate supplements like Preservision AREDS 2?
The product is classified as a dietary supplement and is therefore regulated by the FDA under the Dietary Supplement Health and Education Act (DSHEA). This means that statements regarding its purpose have not been evaluated by the FDA, and it is not subject to the same approval process as prescription drugs.

Instructions for altering the soft gel or caplet forms (such as crushing) are not present in the regulatory text. Different product forms, such as MiniGels or chewable tablets, are available to address potential swallowing difficulties.
Q: What are the alternatives for someone who cannot tolerate the zinc content in the formula?
While the full AREDS 2 formula is the standard, alternatives that contain the other core components without zinc and copper are commercially available. These alternatives are designed for individuals with zinc sensitivity or those with specific recommendations from a healthcare professional.
