Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • “Black Soybean hull extract” is listed as a grouped ingredient — the label gives one combined amount (120 mg) without saying how much of each component you get.

Vision Support II contains five active ingredients. Astaxanthin is a carotenoid (a naturally occurring pigment) from algae.

Thiamine is vitamin B1. Zeaxanthin and lutein are carotenoids found in the eye that support the macula — the central part of your retina responsible for sharp vision.

Black Soybean hull extract is included for its antioxidant compounds. The product is delivered in softgel capsules made with extra virgin olive oil, safflower oil, corn oil, and mixed tocopherols (vitamin E forms) as inactive ingredients.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Eye health support.
  • We looked for evidence on: Age-related macular degeneration (AMD), Asthenopia (eye strain), Cataracts, Central serous retinopathy, Choroideremia, Diabetic retinopathy — and 4 related terms.
  • The strongest evidence on file: Lutein is rated "Possibly Effective" for Age-related macular degeneration (AMD) (Natural Medicines).
  • Also on file: Lutein is rated "Possibly Effective" for Cataracts.
  • Also on file: Zeaxanthin is rated "Possibly Effective" for Age-related macular degeneration (AMD).

The evidence we hold is limited for most uses in this formula. Astaxanthin shows insufficient reliable evidence for age-related vision loss, cognitive decline, skin aging, and Alzheimer disease.

Zeaxanthin and lutein are both rated possibly effective for age-related macular degeneration (AMD) — the progressive eye condition that damages central vision — though the overall evidence base remains modest. Thiamine, when used alone for thiamine deficiency or Wernicke-Korsakoff syndrome, is rated effective, but its role as part of a vision blend hasn't been established.

We hold no effectiveness data for Black Soybean hull extract or Cyanidin-3-Glucosides in the context of vision support.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

The ingredients in this product are generally well tolerated at typical supplement doses. Astaxanthin may cause abdominal pain, diarrhea, or red-colored stools; long-term safety data are limited.

Lutein and zeaxanthin are well tolerated, with lutein showing no adverse effects at doses up to 20 mg daily. Thiamine is very safe when taken by mouth, though rare allergic reactions are possible.

For pregnancy, astaxanthin has insufficient data — the safety data advises against use. Thiamine is needed in pregnancy and is likely safe, but use only supplement doses advised by your doctor.

Zeaxanthin and lutein are likely safe in pregnancy from food sources, though supplement safety is not well studied — discuss with your provider. For breastfeeding, astaxanthin should be avoided due to lack of data; thiamine is needed and likely safe at recommended amounts; zeaxanthin and lutein are likely safe from food but lack robust safety data for concentrated supplements.

Talk with your doctor or pharmacist before starting if you're pregnant or nursing.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Thiamine, Astaxanthin, Zeaxanthin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 755 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your medications if you take drugs metabolized by the CYP3A4 or CYP2B6 liver enzymes (Moderate concern with astaxanthin) — a pharmacist can tell you if yours are affected. If you're on antidiabetes drugs, be aware of the theoretical risk of low blood sugar with zeaxanthin.

If you take trimethoprim (an antibiotic), thiamine may increase your blood levels of that drug.

Astaxanthin2 drug types · 671 drugs

Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP2B6.
In vitro research shows that astaxanthin induces cytochrome CYP2B6 enzyme activity in human hepatocytes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes. This effect has not been reported in humans.

Black Soybean hull extract12 drug types · 611 drugs

Monoamine Oxidase Inhibitors (Maois)

Taking soy products containing high amounts of tyramine along with MAOIs can increase the risk of hypertensive crisis.
Fermented soy products such as tofu and soy sauce contain tyramine, a naturally occurring chemical that affects blood pressure regulation. The metabolism of tyramine is decreased by MAOIs. Consuming more than 6 mg of tyramine while taking an MAOI can increase the risk of hypertensive crisis. The amount of tyramine in fermented soy products is usually less than 0.6 mg per serving; however, there can be significant variation depending on the specific product used, storage conditions, and length of storage. Storing one brand of tofu for a week can increase tyramine content from 0.23 mg to 4.8 mg per serving. Advise patients taking MAOIs to avoid fermented soy products that contain high amounts of tyramine.

Likelihood Likely Evidence C
Antidiabetes Drugs

Soy can lower blood glucose and have additive effects with antidiabetes drugs.
Clinical research shows that whole soy diets and soy-based meals reduce fasting glucose levels in diabetic and non-diabetic individuals. Also, individuals following a soy-based meal replacement plan seem to require lower doses of sulfonylureas and metformin to manage blood glucose levels when compared with individuals following a diet plan recommended by the American Diabetes Association.

Likelihood Possible Evidence A
Antihypertensive Drugs

Theoretically soy protein may have additive effects with antihypertensive drugs and increase the risk of hypotension.
Although some contradictory research exists, most clinical evidence suggests that consuming soy protein modestly reduces systolic and diastolic blood pressure in individuals with prehypertension or hypertension.

Likelihood Possible Evidence A
Caffeine

Theoretically, soy might reduce the clearance of caffeine.
Soy contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females. This effect has been attributed to inhibition of the cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if this effect occurs with the lower amounts of genistein found in soy.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, soy might have additive effects when used with diuretic drugs.
Animal research suggests that genistein, a soy isoflavone, increases diuresis within 6 hours of subcutaneous administration in rats. The effects seem to be similar to those of furosemide. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, soy might competitively inhibit the effects of estrogen replacement therapy.
Soy contains phytoestrogens and has been shown to have estrogenic activity in some patients. Although this has not been demonstrated in humans, theoretically, concomitant use of soy with estrogen replacement therapy might reduce the effects of the estrogen replacement therapy.

Likelihood Possible Evidence D
Levothyroxine (Synthroid, Others)

Soy products might reduce the absorption of levothyroxine in some patients.
Preliminary clinical research and a case report suggest that soy-based formulas inhibit the absorption of levothyroxine in infants with congenital hypothyroidism. A levothyroxine dosage increase may be needed for infants with congenital hypothyroidism while using soy-based formulas, and the dose may need to be reduced when soy-based formulas are no longer administered. However, in postmenopausal adults, clinical research shows that taking a single dose of soy extract containing isoflavones 60 mg along with levothyroxine does not affect the oral bioavailability of levothyroxine.

Likelihood Possible Evidence B
Progesterone

Theoretically, combining soy isoflavones with transdermal progesterone may worsen bone density.
Clinical research suggests that significant bone loss may occur in females with osteoporosis who receive a combination of transdermal progesterone with soy milk containing isoflavones when compared with placebo, soy milk alone, or progesterone alone.

Likelihood Possible Evidence A
Tamoxifen (Nolvadex)

Theoretically, estrogenic soy isoflavones might alter the effects of tamoxifen.
Laboratory research suggests that genistein and daidzen, isoflavones from soy, can antagonize the antitumor effects of tamoxifen under some circumstances; however, soy isoflavones might have different effects when used at different doses. A relatively low in vitro concentration of soy isoflavones such as 1 microM/L seems to interfere with tamoxifen, whereas high in vitro concentrations such as those >10 microM/L might actually enhance tamoxifen effects. People on a high-soy diet have soy isoflavones levels ranging from 0.1-6 microM/L. Until more is known, advise patients taking tamoxifen to avoid therapeutic use of soy products.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, soy might interfere with the effects of warfarin.
Soy milk has been reported to decrease the international normalized ratio (INR) in a patient taking warfarin. The mechanism of this interaction is not known. However, animal and in vitro research suggests that soy may also inhibit platelet aggregation. Dosing adjustments for warfarin may be necessary.

Likelihood Possible Evidence D
Antibiotic Drugs

Theoretically, antibiotics may decrease the activity of soy isoflavones.
Intestinal bacteria are responsible in part for converting soy isoflavones into their active forms. Antibiotics may decrease the amount of intestinal bacteria and decrease its ability to convert isoflavones.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Soy might modestly induce CYP2C9 enzymes. However, this effect does not seem to be clinically significant.
In vitro research suggests that an unhydrolyzed soy extract might induce CYP2C9. However, the significance of this interaction is likely minimal. In healthy females taking a specific extract of soy (Genistein Soy Complex, Source Naturals), blood levels of losartan, a CYP2C9 substrate, were not significantly affected.

Likelihood Unlikely Evidence D
Black Soybean hull extract full monograph & interactions

Zeaxanthin1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, taking zeaxanthin with antidiabetes drugs might increase the risk of hypoglycemia.
In an animal diabetic model, zeaxanthin has hypoglycemic effects. However, population research has found that increasing intake of dietary zeaxanthin plus lutein does not decrease the risk of developing type 2 diabetes.

Likelihood Possible Evidence D
Zeaxanthin full monograph & interactions

Thiamine1 drug type · 3 drugs

Trimethoprim (Proloprim)

Trimethoprim might increase blood levels of thiamine.
In vitro, animal, and clinical research suggest that trimethoprim inhibits intestinal thiamine transporter ThTR-2, hepatic transporter OCT1, and renal transporters OCT2, MATE1, and MATE2, resulting in paradoxically increased thiamine plasma concentrations.

Vision Support II by AOR Advanced Orthomolecular Research Advanced: Common Questions

Does Vision Support II by AOR Advanced Orthomolecular Research Advanced interact with any medications?
Yes. Based on its ingredients, Vision Support II has a known interaction with 1,124 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vision Support II contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does this product actually work for vision loss or macular degeneration?
The evidence we hold is mixed. Zeaxanthin and lutein are both rated possibly effective for age-related macular degeneration, which is the main vision concern this product targets. However, the overall evidence base is modest, not definitive. Talk to your eye doctor about whether this formula is right for your specific situation.
Can I take this if I'm pregnant or breastfeeding?
Astaxanthin should be avoided — there isn't enough safety data. Thiamine is needed and likely safe at recommended doses under your doctor's guidance. Zeaxanthin and lutein are likely safe from food sources, but supplement safety in pregnancy and breastfeeding isn't well studied. Discuss this product with your doctor or pharmacist before starting.
What side effects might I get from Vision Support II?
Most people tolerate it well. Astaxanthin may cause abdominal pain, diarrhea, or red-colored stools. Thiamine rarely causes allergic reactions. Lutein and zeaxanthin at typical doses haven't been linked to side effects in the data we hold.
What is astaxanthin and why is it in this product?
Astaxanthin is a pigment from algae with antioxidant properties. It's included for potential eye and skin support, though the evidence we hold is still developing. It does interact with how your liver processes certain medications, so check your drug list before starting.
Is Black Soybean hull extract a major active ingredient?
Black Soybean hull extract is included for its antioxidant compounds. We don't have detailed individual ingredient data for it because it's listed as a blend or group ingredient. Its specific role in vision support hasn't been established in the evidence we hold.
Are there any fillers in this product?
The inactive ingredients are extra virgin olive oil, safflower oil, corn oil, mixed tocopherols, and the softgel capsule itself — all common carriers and capsule materials used in supplements.
