Choosing A Vision SupplementChoosing A Vision Supplement: Ten Checks
Ten questions, each answerable from a label in under a minute, then applied in public to the product this website sells.
Are the amounts printed? Is a blend hiding the split? Are lutein and zeaxanthin there? Do the antioxidants come near their trials? Do the seals name anybody? Applied here, the product sold on this website clears five and fails four.
A scorecard you can carry to any bottle, and a worked example at the end that is not flattering.
The ten checks, in the order worth running them
Nine of the ten are answerable from the bottle alone. The tenth needs the seller's terms.
1. Are all the ingredient amounts printed?
A Supplement Facts panel must give the amount of every declared nutrient. What it may withhold is the split inside a proprietary blend, which is a legal format that declares a total weight and a list of components in descending order and no figure for any single one.
This is the first check because everything downstream depends on it. An amount you cannot see is an amount you cannot compare with a trial.
2. Is there a proprietary blend, and how much of the bottle is inside it?
Blends are legal and common. The question is proportion. A blend carrying a minor flavouring is different from a blend that holds the ingredients the front label is selling.
Read the blend total against the rest of the panel. If the blend outweighs the declared nutrients, the bottle's most important number is the one nobody has published.
3. Does it carry lutein and zeaxanthin, and at what amounts?
These are the two ingredients that define a modern eye formula, and AREDS2 gave them at 10 mg and 2 mg a day. A bottle carrying neither is a broad multivitamin with an eye-shaped label, which may still be a reasonable purchase and is a different object from what most buyers think they are getting.
4. Do the antioxidant amounts come anywhere near the trials they borrow from?
Vitamin C 500 mg, vitamin E 400 IU and zinc 80 mg are the AREDS figures, with 25 mg of zinc the useful lower comparison from AREDS2. Set each row against those. A fraction is not a failure on its own, but a bottle at a tenth of a trial dose should not be described as an AREDS-type formula by anybody.
5. If the zinc is high, is copper there too?
Sustained high-dose zinc depletes copper, which is why both trials carried 2 mg of cupric oxide. Above roughly 25 mg of zinc, the absence of copper is a real gap. Below it, the question does not arise and the absence is consistent.
6. Are the forms named, and are they the ones the trials used?
The words in brackets carry the real dose. Magnesium oxide delivers less than magnesium citrate at the same weight. DL-alpha tocopheryl acetate is the synthetic vitamin E. Zinc oxide is what AREDS used, which makes that comparison clean.
A panel that names its forms is being straightforward. A panel that names only the element is leaving out the part that decides how much arrives.
7. Does the panel's own arithmetic check out?
Take any row, divide the amount by the FDA Daily Value for an adult, and see whether the printed percentage falls out. It is a two-minute check on a whole panel and it is the only quality signal on a bottle that can be verified from the outside.
A panel whose percentages disagree with its own weights was assembled carelessly, and carelessness in the one place a buyer can see is worth weighing.
8. Is the allergen line there, and does it match the ingredient list?
Soy, gelatin, shellfish and dairy all reach supplements through inactive ingredients and through extracts. Read the allergen statement and then read the ingredient list again to see whether the two agree.
A blend containing plant sterols from soy while the allergen line says nothing is a genuine problem. A label that says so twice is doing its job.
9. Do the seals name anybody?
A seal that names its certifier can be looked up. A seal that names nobody cannot, and most seals on most supplement packs name nobody.
Two specific ones are worth recognising. An FDA-registered facility mark refers to a registration filed with the agency rather than to an inspection or an approval. A GMP mark without a certifier's name asserts compliance with a rule that United States law already requires of every manufacturer.
10. Is there a refund you can actually reach, with a person on the telephone?
The last check is commercial and it is the one that costs money when it is skipped. Find the window, find out what day it starts from, find out who pays return postage, and find a telephone number that reaches somebody who can see an order.
A window counted from purchase rather than from delivery is shorter than it looks, and it is worth checking whether the largest pack on the ladder outlasts it.
Why these ten and not others
Ordered so the cheapest information comes first.
Each check exists because it separates two bottles that look identical on a shelf. A front label saying supports eye health tells a buyer nothing, because every bottle in the category says it and the law does not permit anything stronger.
The checks are ordered so that the cheapest information comes first. Checks one to three take about ninety seconds with the bottle in your hand and will settle most decisions on their own. Checks four to seven need the amounts from the guide and a moment's arithmetic. Checks eight to ten are about what happens after the purchase.
The amounts every check compares against are set out, with their trials, in the vision supplement guide.
OptiCore Pro scored against all ten checks
Ten checks, applied without adjustment to the product sold here.
The product this website sells, run through the same scorecard without adjustment. Four rows fail outright, a fifth takes a partial, and five pass. The failures are unpacked first below, because those are the ones worth having before an order rather than after one.
| Check | Result | Why |
|---|---|---|
| 1. All amounts printed? | Partial | Sixteen declared nutrients each carry a weight and a per cent Daily Value. The seventeenth row gives 179.5 mg for eleven plants together and no figure for any one of them. |
| 2. Proprietary blend, and how much? | Fail | There is one, at 179.5 mg, covering 11 botanicals in descending order with no split. Eleven of this bottle's twenty-seven named ingredients have no amount a reader can check. |
| 3. Lutein and zeaxanthin? | Fail | Neither appears on the panel. These are the two ingredients AREDS2 is known for, at 10 mg and 2 mg, and this is a broad multivitamin sold for the eye rather than an AREDS2-style formula. |
| 4. Antioxidants near the trial amounts? | Fail | Vitamin C 60 mg against 500 mg, vitamin E 7 mg against 400 IU, zinc 3.62 mg against 80 mg or the lower 25 mg arm. Every one is a fraction, and the largest figure on the panel belongs to biotin, which has no vision trial at any amount. |
| 5. Copper with high zinc? | Pass | No copper, and none needed. At 3.62 mg the zinc is nowhere near the amount that depletes copper, so the absence is internally consistent rather than a gap. |
| 6. Forms named? | Pass | Every row names its form: beta-carotene, ascorbic acid, cholecalciferol, DL-alpha tocopheryl acetate, thiamin mononitrate, pyridoxine HCl, cyanocobalamin, calcium carbonate, ferrous fumarate, magnesium oxide, zinc oxide, manganese amino acid chelate, potassium gluconate. Two of those forms are the cheap end, and naming them is what lets a reader know. |
| 7. Panel arithmetic correct? | Pass | All sixteen percentages were recomputed against the current FDA Daily Values and every one agrees to within a rounding step. The working is on the supplement facts page. |
| 8. Allergen line present and consistent? | Pass | The other-ingredients line reads “Contains: Soy” and the blend separately names plant sterols from soy bean. The label declares the allergen its own blend contains, which is the correct outcome. |
| 9. Do the seals name anybody? | Fail | Three of the four marks name no organisation at all. The FDA roundel refers to a registration rather than an inspection, the GMP seal names no certifier, and the money-back seal carries no day count. Only the ingredient-origin seal is confirmed by the printed label. |
| 10. Refund route with a telephone number? | Pass | 180 days, opened bottles included, with an order desk on +1 (302) 200-3480. The window is counted from purchase rather than delivery, and the six-bottle pack outlasts it, which check ten tells you to look for. |
Five passes, one partial and four failures. A commercial website publishing four failures against its own product is the whole reason this page is worth reading.
What the four failures mean for a buyer
Four rows in three groups, and what each group costs the buyer.
The blend, check two
Eleven of this bottle's named ingredients sit inside 179.5 mg with no individual figure. That is legal and common, and it means no plant in the blend can be set against a trial of that plant. Two of them, nettle root and saw palmetto, have single-plant trials whose daily amount is larger than the whole blend weighs.
The missing carotenoids, checks three and four
Lutein and zeaxanthin are absent and the antioxidant amounts are a fraction of the trial figures. Anybody arriving expecting an AREDS2-style formula is looking at the wrong product, and the honest description of this one is a broad multivitamin built around the eye rather than a trial formulation.
The seals, check nine
Three of four marks name nobody, so nothing on them can be verified by anybody outside the supply chain. That is the ordinary state of a supplement pack rather than a scandal, and it is the reason a seal wall should be audited rather than admired. The testing and quality page does that one at a time.
What the five passes are worth
Five rows the product clears, stated with the same care as the four it does not.
A scorecard that only reported failures would be as useless as one that only reported passes, so the other side belongs here too.
The sixteen declared amounts are genuinely printed, the forms are named down to the salt, and the percentages all compute correctly against the current FDA reference values. That combination is more than a good deal of this category offers, and it is what makes the comparison with the trials possible at all.
The allergen line does its job, declaring the soy its own blend contains. And the refund route is the strongest single thing about the purchase: 180 days from the date of purchase, opened bottles included, with a telephone number that reaches somebody who can see an order.
The tenth check's own warning applies even so. A window counted from purchase is shorter than it looks, and the six-bottle pack on this ladder outlasts it by about nine days. The guarantee page has the calendar.
Carrying this scorecard to a different bottle
Ten checks that work on any bottle in this category.
The point of ten checks is that they work on anything in the category. A reader who runs them on three bottles in a shop will find that most fail checks one and two, that check nine almost never passes anywhere, and that check ten separates sellers far more sharply than the panels do.
Two closing notes. A bottle that fails several of these can still be a reasonable purchase for somebody whose diet is narrow and who wants one capsule rather than four. And a bottle that passes all ten is still not a treatment for an eye condition, because no supplement is. Four failures out of ten is a middling score in this category rather than an unusually poor one, which is itself worth knowing.
For an actual eye complaint, the National Eye Institute and MedlinePlus are free and considerably more useful than any product page, this one included.
