Choosing supplements for seniors is easy — choosing well takes a method. What should seniors look for in the supplement aisle? Here is how — part fifteen.

First, check the ingredients. Are the ingredients in the product the ones that research has studied — at the dose the research studied? Check whether the label names them — and at what dose. A product that hides its ingredients behind a proprietary blend is a product that is not telling you the whole story.

Second, check the dose. An ingredient studied at 1,000 mg a day, present at 100 mg in the product, is not evidence for the product — it is evidence for a different dose. Check whether the dose matches the research — and whether the form matches too. A low dose, at a high price, is poor value — however good the marketing.

Third, check the form. Is the ingredient in its studied form — or a cheaper substitute? A form that is absorbed well is worth more than a form that is not. Check the form — and ask whether it matches the research. A product that uses the studied form is a product worth trusting.

Fourth, check who paid for it. Was the study funded by the brand that sells the product — or by an independent body? A study funded by the brand is a study that should be read with care. A study funded independently is a study worth trusting. Check who paid — and ask whether they had an interest in the result.

Fifth, check the result — not the headline. Did the study show a large effect — or a small one? A headline that says "works" can hide an effect so small it does not matter. Check the numbers — how big was the difference, and was it meaningful? A small difference, however real, is still a small difference.

Sixth, check whether other studies agree. Does this study stand alone — or do other studies say the same thing? One study, however good, is not enough. A body of studies, pointing the same way, is worth trusting. Check whether other studies agree — and ask whether the evidence is consistent.

Seventh, check the date. When was the study published — and has anything newer changed the picture? Research moves — and a study from twenty years ago may not be the last word. Check the date — and ask whether it is recent.

Choosing supplements for seniors is not complicated. Ingredients, dose, form, funding, result, agreement, date. Seven checks — and the evidence, not the marketing, decides.

Independent reviews can help you choose. The Supplement Rating publishes evidence-led reviews that start with the label, check doses against research, examine testing disclosure and state their limits plainly — and its safety checklist covers the five checks that matter most before you buy. a review of a botanical eye-health formula shows the method in practice: label first, dose second, evidence third, verdict last.
