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 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Opti Gold contains six active ingredients. Alpha-lipoic acid is an antioxidant that may help with nerve damage from diabetes and cholesterol.

Vitamin A supports vision and immune function. Taurine is an amino acid involved in heart and liver health.

FloraGLO lutein and zeaxanthin are carotenoids that protect your eyes, especially from age-related damage. Bilberry extract, a 4:1 concentration, provides anthocyanins that may support eye and cognitive health.

The product also contains inactive ingredients—rice flour, vegetable cellulose, magnesium stearate, and others—that serve as fillers and binders.

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: vision support.
  • We looked for evidence on: Age-related macular degeneration (AMD), Asthenopia (eye strain), Cataracts, Diabetic retinopathy, Retinal health, Blue light protection — and 1 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).

For alpha-lipoic acid, there is possibly effective evidence for diabetic nerve damage, high cholesterol, and weight management. Vitamin A is effective for vitamin A deficiency and possibly effective for mouth sores, aging skin, measles, ulcerative colitis, and lung disease in premature infants.

Taurine is possibly effective for liver inflammation and heart failure, but possibly ineffective for weight loss. Lutein is possibly effective for age-related macular degeneration and cataracts, but possibly ineffective for other retinal conditions.

Bilberry extract has insufficient evidence to rate for most uses, and was found possibly ineffective only for night vision. Zeaxanthin is possibly effective for age-related macular degeneration but has insufficient evidence for cognitive decline, Alzheimer's, asthma, breast cancer, and lung disease.

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 5 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Alpha-lipoic acid is generally well tolerated but can lower blood sugar and should be used under medical guidance; it may cause headache, heartburn, nausea, or skin rash, and there's not enough safety data in pregnancy or while breastfeeding. Vitamin A at recommended doses is safe, but high doses accumulate in your body and can cause liver damage, birth defects, and serious brain and vision effects—avoid high-dose supplements in pregnancy, though normal dietary and recommended amounts are needed.

Taurine is generally well tolerated short-term in healthy adults, though long-term safety is less certain; common side effects include constipation, diarrhea, and indigestion, and supplement safety during pregnancy and breastfeeding is not well studied. Lutein from food and typical supplement doses is generally safe; no adverse effects were reported at doses up to 20 mg daily.

Bilberry fruit is well tolerated but may cause dark stools, gas, and stomach discomfort; avoid concentrated supplements in pregnancy and breastfeeding due to lack of safety data. Zeaxanthin is generally well tolerated at typical doses; dietary amounts are fine, but supplement safety in pregnancy and breastfeeding is not well studied.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 5 of the 6 matched ingredients can interact with medications — Bilberry, Alpha-lipoic Acid, Vitamin A, Taurine, Zeaxanthin.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; cancer treatments; diabetes medications; lithium.
  • For scale: 771 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 with your doctor or pharmacist before taking this if you use blood thinners or antiplatelet drugs (increased bleeding risk from alpha-lipoic acid and bilberry), retinoid medications like isotretinoin or tretinoin (major risk of vitamin A toxicity), blood pressure medications (taurine may lower pressure further), diabetes drugs (alpha-lipoic acid, bilberry, and zeaxanthin may raise low blood sugar risk), thyroid hormones (alpha-lipoic acid may reduce effectiveness), chemotherapy drugs (alpha-lipoic acid's antioxidant effects may interfere), tetracycline antibiotics (vitamin A may raise brain pressure risk), lithium (taurine may increase levels), liver-toxic drugs (vitamin A may add to risk), erlotinib or other CYP2E1 substrate drugs (bilberry may reduce effectiveness), or warfarin specifically (vitamin A may increase bleeding risk).

Each ingredient & the kinds of drugs it affects

For each ingredient in Opti Gold with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Vitamin A4 drug types · 387 drugs

Retinoids

Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.

Likelihood Possible Evidence C
Tetracycline Antibiotics

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Likelihood Possible Evidence D
Vitamin A full monograph & interactions

Bilberry 4:1 extract4 drug types · 275 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro, animal, and clinical research suggest that anthocyanidin extracts from bilberry can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity. Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity. This effect has not been reported in humans.

Likelihood Possible Evidence D
Erlotinib (Tarceva)

Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Bilberry 4:1 extract full monograph & interactions

Alpha Lipoic Acid5 drug types · 263 drugs

Alkylating Agents

Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of alkylating agents.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy. Advise patients to consult their oncologist before using alpha-lipoic acid.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, alpha-lipoic acid may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro, alpha-lipoic acid inhibits platelet aggregation.

Likelihood Possible Evidence D
Antitumor Antibiotics

Theoretically, the antioxidant effects of alpha-lipoic acid might alter the effectiveness of antitumor antibiotics.
The use of antioxidants like alpha-lipoic acid during chemotherapy is controversial. There are concerns that antioxidants could reduce the activity of antitumor antibiotic drugs, which work by generating free radicals. However, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that might interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as alpha-lipoic acid have on chemotherapy involving antitumor antibiotics. Advise patients to consult their oncologist before using alpha-lipoic acid.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, alpha-lipoic acid might decrease the effects of thyroid hormone drugs.
Animal research suggests that co-administration of thyroxine with alpha-lipoic acid reduces conversion into the active T3 form.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking alpha-lipoic acid with antidiabetes drugs might increase the risk of hypoglycemia.
Although some small clinical studies have suggested that alpha-lipoic acid can lower blood glucose levels, larger clinical studies in patients with diabetes have shown no clinically meaningful effect. Additionally, co-administration of single doses of alpha-lipoic acid and glyburide or acarbose did not cause detectable drug interactions in healthy volunteers.

Likelihood Unlikely Evidence B
Alpha Lipoic Acid full monograph & interactions

Taurine2 drug types · 173 drugs

Antihypertensive Drugs

Theoretically, taurine might increase the risk of hypotension when taken with antihypertensive drugs.
Some clinical evidence suggests that taurine can reduce both systolic and diastolic blood pressure.

Likelihood Probable Evidence D
Lithium

Theoretically, taurine might reduce excretion and increase plasma levels of lithium.
Taurine is thought to have diuretic properties, which might reduce the excretion of lithium.

Likelihood Probable Evidence D
Taurine 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.

Opti Gold by Botanic Choice: Common Questions

Does Opti Gold by Botanic Choice interact with any medications?
Yes. Based on its ingredients, Opti Gold has a known interaction with 770 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?
Opti Gold contains 6 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.
Can I take Opti Gold if I'm pregnant?
There is not enough reliable safety data for most of these ingredients during pregnancy. Vitamin A at high doses can cause birth defects, though normal dietary and recommended amounts are needed; alpha-lipoic acid and bilberry lack sufficient pregnancy data. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy.
What are the most common side effects I might notice?
Alpha-lipoic acid may cause headache, heartburn, or nausea. Bilberry can cause dark-colored stools, gas, or stomach discomfort. Taurine may cause constipation or diarrhea. These tend to be mild, but if they persist, mention them to your pharmacist.
Does this product actually help with vision?
Lutein and zeaxanthin are possibly effective for age-related macular degeneration based on current evidence. Bilberry has insufficient evidence for most eye uses. Alpha-lipoic acid, vitamin A, and taurine were not rated for vision specifically, though vitamin A supports eye health.
Can I take this with my blood pressure medication?
Taurine in this product may theoretically lower blood pressure further, so you should check with your doctor or pharmacist before combining them. They can tell you whether it's safe for you or if monitoring is needed.
Is this safe to use long-term?
Alpha-lipoic acid and lutein are generally well tolerated. Taurine's long-term safety is less certain. Bilberry supplement long-term safety evidence is limited. It's best to discuss ongoing use with your doctor or pharmacist.
What is FloraGLO lutein?
FloraGLO is a branded form of lutein, a carotenoid naturally found in leafy greens and other foods. It's used in supplements to support eye health, particularly for age-related macular degeneration and cataracts.
