Quick Answer
iGenics at a Glance
iGenics is one of the better-dosed eye supplements we've reviewed. Its 20 mg lutein and 10 mg zeaxanthin exceed the AREDS2 trial levels, and the botanical stack — bilberry at 480 mg, saffron at the 20 mg clinically-studied dose, turmeric at 350 mg with BioPerine for absorption — is more comprehensive than most competitors. The 180-day money-back guarantee is the most generous in the category. Where we'd moderate expectations: some sales-page claims are overstated; meaningful results from any carotenoid supplement take 60–90+ days, not seven.

What Is iGenics?
iGenics is a dietary supplement manufactured by Science Genics, a supplement company based in Ohio. The formula is built around 12 ingredients targeting retinal health through two parallel mechanisms: delivering high-dose carotenoids to the macula, and reducing the systemic inflammatory environment that accelerates oxidative damage in retinal tissue.
The ingredient list exceeds the AREDS2 standard on carotenoid dosing and adds botanicals not included in the original NIH trial: bilberry extract at 480 mg, saffron at 20 mg (the dose used in published RCTs), turmeric at 350 mg with BioPerine, and ginkgo biloba for retinal microcirculation.
It's made in an FDA-registered, GMP-certified facility in the United States. Available only through the official website, processed via ClickBank or BuyGoods.
iGenics Ingredients: All 12, With Doses
| Ingredient | Dose | AREDS2 Dose | Role |
|---|---|---|---|
| Lutein | 20 mg | 10 mg | Macular pigment; blue-light filter |
| Zeaxanthin | 10 mg | 2 mg | Macular pigment co-factor |
| Bilberry Extract | 480 mg | — | Retinal microcirculation; anthocyanins |
| Saffron Extract | 20 mg | — | Photoreceptor protection (RCT-supported dose) |
| Turmeric Extract | 350 mg | — | Anti-inflammatory; curcumin pathway |
| Black Pepper (BioPerine) | 20 mg | — | Curcumin bioavailability +2,000% |
| Ginkgo Biloba | Not disclosed | — | Retinal blood flow; microcirculation |
| Vitamin A | Not disclosed | — | Rhodopsin synthesis; night vision |
| Vitamin C | Not disclosed | 500 mg | Lens/retinal antioxidant |
| Vitamin E | Not disclosed | 400 IU | Retinal lipid protection |
| Zinc | Not disclosed | 80 mg | Retinal enzyme function (AREDS2) |
| Copper | Not disclosed | 2 mg | Prevents zinc-induced depletion |
Doses disclosed by the manufacturer. Some vitamins and minerals are listed without specific mg — this is a transparency limitation.
1. The Carotenoid Core: Lutein 20 mg + Zeaxanthin 10 mg
The AREDS2 trial (NIH, n=4,203) established 10 mg lutein + 2 mg zeaxanthin as the standard for macular support. iGenics doubles the lutein dose and quintuples the zeaxanthin. Higher doses increase macular pigment optical density (MPOD) more effectively, which is the primary measurable biomarker for these nutrients. This is a genuine formulation strength.
2. Bilberry 480 mg
Bilberry (Vaccinium myrtillus) is high in anthocyanins — blue-purple plant pigments that cross the blood-retinal barrier and support retinal microcirculation. At 480 mg, iGenics delivers one of the higher bilberry doses available in the supplement market. Research in pilots and night-vision studies has linked bilberry to improved dark adaptation, though effect sizes are modest and dose-response is still being established.
3. Saffron 20 mg — The Clinically-Studied Dose
Saffron at 20 mg/day is the exact dose used in the 2010 RCT published in Investigative Ophthalmology & Visual Science that found improved ERG function in early AMD patients. The active compounds crocin and crocetin appear to protect photoreceptors from oxidative damage. This is an evidence-backed dose, not a token inclusion.
4. Turmeric 350 mg + BioPerine 20 mg
Curcumin (turmeric's active compound) is poorly bioavailable on its own — around 3–5% absorption. BioPerine (piperine from black pepper) increases curcumin bioavailability by approximately 2,000%, making the 350 mg effective rather than cosmetic. Curcumin has published evidence for reducing inflammatory cytokine activity — the same pathways implicated in chronic low-grade retinal inflammation.
5. Ginkgo Biloba
Ginkgo biloba extract has been studied for its role in improving ocular blood flow, including in the context of normal-tension glaucoma. While evidence for AMD specifically is limited, retinal microcirculation — the capillary network feeding photoreceptors — benefits from improved peripheral blood flow. The dose is not disclosed, which is a transparency issue.
iGenics vs AREDS2 — How It Stacks Up
The AREDS2 trial is the gold standard for macular supplement research. Here's how iGenics compares.

| Zeaxanthin | 10 mg ✓✓ | 2 mg | 2 mg |
| Vitamin C | Present | 500 mg | 500 mg |
| Vitamin E | Present | 400 IU | 400 IU |
| Zinc + Copper | Present | 80 mg / 2 mg | 80 mg / 2 mg |
| Bilberry | 480 mg ✓ | — | — |
| Saffron 20 mg | ✓ | — | — |
| Turmeric + BioPerine | 350 mg ✓ | — | — |
| Price/bottle | $39–59 | — | $22–28 |

What Customers Are Saying
Robert H.
Seattle, WA
Been on iGenics for 4 months. My ophthalmologist said my macular pigment reading was noticeably better at my last checkup. Didn't mention I was taking it beforehand — she noticed first.
Linda G.
Phoenix, AZ
I compared it to PreserVision and went with iGenics because of the higher lutein dose and the saffron. The 180-day guarantee made it a no-brainer. Three months in and the halos at night are definitely reduced.
Michael F.
Atlanta, GA
Screen fatigue was brutal working from home. Two months on this and by late afternoon my eyes don't feel like sandpaper anymore. Sticking with it.
Carol W.
Denver, CO
My retina specialist knows I take supplements. He looked at the iGenics ingredient list and said the dosing was solid — specifically mentioned the lutein level and the saffron. That was enough for me.

Who Is iGenics For?
Good fit:
- Adults 40+ concerned about age-related macular changes who want AREDS2-level or above coverage
- People who've tried basic lutein supplements and want higher doses or a more complete formula
- Those who want the saffron and bilberry botanicals not available in pharmacy-brand AREDS2
- Anyone who values the security of a 180-day refund window
Not the best fit:
- People whose primary concern is gut-driven inflammation (see VisiFlora for the gut-eye angle)
- Anyone with advanced macular disease — supplements don't replace specialist care
- Those looking for immediate results — 60–90+ days is the realistic minimum

Frequently Asked Questions
What is iGenics?
iGenics is a 12-ingredient supplement by Science Genics built around a high-dose AREDS2 carotenoid profile (lutein 20 mg, zeaxanthin 10 mg) plus botanicals: bilberry 480 mg, saffron 20 mg, turmeric 350 mg with BioPerine, and ginkgo biloba.
How does iGenics compare to AREDS2?
iGenics includes all core AREDS2 nutrients (lutein, zeaxanthin, vitamins C/E, zinc, copper) and exceeds AREDS2 on carotenoid dosing — 20 mg lutein vs 10 mg in AREDS2, and 10 mg zeaxanthin vs 2 mg. It adds botanicals not in AREDS2: bilberry, saffron, turmeric, ginkgo.
Does iGenics have a money-back guarantee?
Yes — 180 days (6 months), no return required. This is one of the most generous guarantees available for any eye supplement.
How long does iGenics take to work?
Realistic timeframe is 60–90 days minimum. Carotenoids accumulate in macular pigment gradually. Studies measuring MPOD changes typically run 3–6 months. Ignore any claims of results in days.
Is iGenics FDA approved?
No supplement is FDA-approved. iGenics is manufactured in an FDA-registered, GMP-certified US facility, meaning production meets federal quality standards.
Is iGenics better than VisiFlora?
Different, not strictly better. iGenics focuses on higher carotenoid doses and botanicals. VisiFlora focuses on the gut-eye axis — addressing how gut barrier integrity affects retinal inflammation. The best choice depends on which mechanism matters more for your situation. Some people take both.
Final Verdict
iGenics earns a straightforward recommendation for anyone who wants AREDS2-equivalent or above carotenoid coverage with the addition of botanicals not available in pharmacy brands. The 20 mg lutein and 10 mg zeaxanthin doses are clinically meaningful. The saffron is at the 20 mg level used in actual RCTs. The bilberry at 480 mg is genuinely high. BioPerine makes the turmeric work.
The transparency limitation — some vitamins and minerals without specific doses — is a real weakness. And the sales page overclaims on timeline. But those are marketing issues, not formulation issues. The formula itself is solid.
The 180-day guarantee removes the financial risk entirely. If it's not working at 6 months, you haven't lost anything.
