Upper intake level
Adults, 2,000mg a day, from food, beverages and supplements together. One serving of this product holds 1,000mg, less than that level on its own.
An upper intake level is the largest daily intake unlikely to cause harm for most people. It is not a recommendation about what to take.

- Printed on this bottle's own panel image as "Vitamin C (as Quali®-C Ascorbic acid) 1000 mg 1111%" in a "Serving Size: 2 Capsules" serving with "Servings per Container: 30", and the front prints "60 Capsules" and "1000 mg/serving". Milligrams of vitamin C are the comparison basis and the panel prints milligrams, so nothing is converted. Vitamin C is the only line in the panel. The liposome is listed among the other ingredients, with no amount, as "Liposomal Complex (Ascorbyl palmitate, Sunflower lecithin, and Phosphatidylcholine)", so there is no second active to mark, and the 1000 mg is the panel's own Vitamin C line. The front and the panel both say liposomal. The label prints "CONTAINS SOY"; it makes no vegan, vegetarian or gluten claim, so those stay Unknown.
Delivery
Delivery cost
Applies, amount not published
Delivery is NOT free on this order. It is $55.01 below the $75.00 threshold, and this retailer does not publish a rate, so we cannot tell you what it will add. Free shipping on orders of $75 or more, from the announcement bar on coremedscience.com, first read August 31, 2026 and read again on September 28, 2026 and October 17, 2026 with the same figure. The shipping policy page itself states no domestic threshold. No rate is published below $75, so delivered cost below it is Unknown and those listings are left out of cheapest-delivered claims.
Cost per dose delivered

We will not put a number on this. The product price is a floor, not the price you will pay. Reaching the free-delivery threshold, or choosing a retailer that publishes its rate, is the only way to know in advance.

Verification, Tier D: Could not locate independent data
We could not locate independent testing or certification for this product. That is a statement about our search, not about the product. These programs certify what a company submits to them, so a product can be absent simply because it was never entered, which is not a finding against it. Which certifier databases we searched, and when, is listed below. Where a program is not listed there, we have not checked it and do not imply anything either way.
- Searched 4 certifier databases and found no listing for this product, and located no published test results. Programs we did not search are named below as not checked.
- Checked NSF Certified for Sport database on Oct 17, 2026: not listed.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked, and no listing names this package. The Certified for Sport directory holds two vitamin C rows under this brand, both "Vitamin C (500mg)": 1802300, filed under "Core Med Science", and 1691898, filed under "Core Med Science / OIAM Performance". Both listing pages, opened on Oct 17, 2026, print Package Size "30" and Serving Size "1 capsule", and the Supplement Facts image each one files prints "Serving Size: 1 Capsule", "Servings Per Container: 30" and "Vitamin C (as Ascorbic Acid) 500mg"; the image filed with 1691898 adds "Other Ingredients: Vegetable Cellulose (from capsule), MCC, Stearic acid, Magnesium Sterate" and its photograph is a white OIAM carton. That is a plain ascorbic acid capsule, 30 to a package. This bottle is liposomal vitamin C, 60 capsules in a 2-capsule serving of 1000 mg with a liposomal complex among its other ingredients, so neither listing names it. The brand's own store sells no 30-capsule vitamin C. Absence from a database is not a failed test.

Same category and format and, for vitamin D, the same labeled strength. Different recorded ingredient-form lists are kept separate.

These are browsing options, not recommended substitutes.
What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
