It is not a customer-review average, independent laboratory result or clinical efficacy score.\u003c\/p\u003e\u003ch2\u003eFormula and daily supply\u003c\/h2\u003e\u003cp\u003eDoNotAge states 400 mg quercetin per capsule, in dihydrate form sourced from Sophora japonica L. The manufacturer’s 800 mg daily serving is two capsules, taken with a source of fat at the first meal. The company says there are no fillers inside the capsule beyond quercetin powder.\u003c\/p\u003e\u003cp\u003eAt two capsules daily, 60 capsules last 30 days and 366 capsules last 183 days. The subscription options provide one 366-capsule container for 400 mg\/day or two for 800 mg\/day, in one annual shipment. These are product quantities and directions, not personal prescribing advice.\u003c\/p\u003e\u003ch2\u003ePrice and quality policy\u003c\/h2\u003e\u003cp\u003eThe US one-time snapshot checked on 18 October 2026 was $35 for 60 capsules and $133 for 366, before discounts, shipping or tax. At two capsules daily, that is approximately $1.17 or $0.73 per day.

We have not independently inspected a lot-specific certificate or assayed this product.

The studies use different forms, populations and regimens. They do not establish the same outcome for this exact DoNotAge formula, nor prove human lifespan extension, dementia prevention or a disease cure.\u003c\/p\u003e\u003cp\u003eOur review compares the label, current product information, quality policy and ingredient literature. We did not perform a hands-on efficacy test or identify published product-specific clinical results establishing those outcomes.\u003c\/p\u003e\u003ch2\u003eWho it suits\u003c\/h2\u003e\u003cp\u003eIt is our preferred option for readers who want one clearly labelled active ingredient and the ability to choose a smaller starting pack or compare larger-pack value. Readers specifically seeking a phospholipid complex or bromelain blend have a different formulation preference.\u003c\/p\u003e\u003cp\u003eCheck your medicines and clinical circumstances before use, particularly anticoagulation, kidney disease, pregnancy, breastfeeding or complex treatment.
