What it is
NOW Foods Sodium Ascorbate Powder is a buffered vitamin C powder in an 8 oz (227 g) bottle, and sodium ascorbate is the only thing in the jar. A serving of 1/2 level teaspoon — given on the panel as approximately 1.9 g — supplies 1,670 mg of vitamin C and 210 mg of sodium, and the bottle holds about 119 of those servings. The front of the bottle reads "Pure, Buffered" above "Vitamin C Powder", with "A Dietary Supplement" and "Vegetarian/Vegan" printed beneath the net weight.
The format is the point of difference. There is no capsule shell and no tablet binder; the powder is scooped, so the serving is whatever you level off in the spoon, and the panel's figures are calculated against that level spoonful. It sits in our Supplements range alongside capsule and tablet forms of the same nutrient.
What's inside
One compound accounts for both lines on the Supplement Facts panel: sodium ascorbate, named as the source of each. Sodium ascorbate is the sodium salt of ascorbic acid — the same vitamin C molecule, with a sodium ion sitting where one of ascorbic acid's acidic hydrogens would be. That substitution is what the word "buffered" on the front panel refers to, and it is also why sodium gets its own nutrient row rather than an ingredient line: the sodium is part of the molecule being measured out, not something stirred in afterwards.
The two rows account for the serving almost exactly. Vitamin C at 1,670 mg plus sodium at 210 mg comes to 1,880 mg, against a serving weight printed as approximately 1.9 g. That arithmetic is the panel's own demonstration of the line directly beneath it — "Other ingredients: None." No filler, no flow agent, no sweetener, no color.
Vitamin C is a water-soluble nutrient the body neither manufactures nor stores in quantity, which is why it turns up so widely in food and in supplement formulas; the NIH Office of Dietary Supplements fact sheet on vitamin C gives general background on the nutrient. This is a concentrated preparation of it: the panel puts one serving at 1,856% of the Daily Value, a figure worth reading before deciding how the powder fits alongside anything else in your routine.
The sodium row is the second number to know. At 210 mg it is 9% of the Daily Value for sodium — a modest share of a day's allowance, but a real one, and it is the trade-off that comes with this particular buffered form. The side panel also describes the powder as non-bitter and highly soluble, both of which are descriptions of the raw material in the bottle. If you want to compare how other manufacturers declare the same compound, the NIH Dietary Supplement Label Database holds transcribed panels from across the category.

How to use it
The bottle's suggested usage is one instruction: take 1/2 level teaspoon daily. Level the spoon rather than heaping it — every figure on the panel is calculated against a level 1/2 teaspoon, so a rounded spoonful puts all of them out by a margin you cannot see.
The panel also states that the product is sold by weight, not volume, and that is worth understanding rather than skimming. The bottle is filled by weight to 227 g; how high the powder sits in the jar depends on how it has settled in transit. It is also why the serving reads "1/2 Level Teaspoon" with "approx. 1.9 g" beside it — the spoon is the convenient measure, the gram figure is the exact one.
Storage is straightforward: keep it in a cool, dry place after opening, as printed on the panel. At one serving a day, about 119 servings works out to roughly a four-month supply from a single 8 oz bottle.
Who it's for
This is a product for adults who already know they want vitamin C in powder form and want it without anything else attached. The single-ingredient panel is the whole proposition — someone comparing labels for a clean declaration will find "Other ingredients: None." hard to improve on. It is stocked under Antioxidants for anyone browsing that part of the catalog by nutrient rather than by brand.
The powder format suits people who would rather not swallow capsules or tablets, and the 8 oz size suits someone who has already settled on a routine rather than someone sampling a nutrient for the first time — 119 servings is a long commitment to one form and one brand. Anyone monitoring their sodium intake should weigh the 210 mg figure against the rest of the day before choosing this form over an unbuffered one. As with any supplement, this is a product for adults 18 and over.
Good to know
- Reading the asterisk. The statements NOW prints on the bottle carry an asterisk pointing to the standard FDA notice. The FDA's page on structure/function claims explains what that asterisk means on any supplement label and why it is there.
- The bottle's own caution. Printed in full: for adults only; consult a physician if pregnant or nursing, taking medication, or managing a medical condition; keep out of reach of children.
- Color. The side panel notes that natural color variation may occur in this product. A shade difference between bottles is expected and is not a fault.
- Allergens. Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients. Produced in a GMP facility that processes other ingredients containing these allergens — the packaging states both halves of that, and the second half matters if you react to trace exposure.
- Marks on the pack. The front panel carries a Non-GMO badge and a "K" inside a triangle; the side panel carries a "GMP Quality Assured" roundel. The bottle itself is printed as being made from 100% PCR (post-consumer recycled) resin.
- Where it comes from. Packaged for NOW Foods, 395 S. Glen Ellyn Rd., Bloomingdale, IL 60108, USA. The panel states the product is packaged and quality tested in the USA.
- Before you combine it with anything. If you take prescription medication or several supplements at once, the NIH page on dietary and herbal supplement safety is a reasonable general starting point for a conversation with your own clinician.

Frequently Asked Questions
How much vitamin C is in one serving?
One serving of 1/2 level teaspoon supplies 1,670 mg of vitamin C, listed on the panel as 1.67 g and as 1,856% of the Daily Value. That figure comes entirely from sodium ascorbate, which is the only compound declared on the label.
Does this powder contain anything besides sodium ascorbate?
No — the Supplement Facts panel reads "Other ingredients: None." There is no filler, sweetener, flow agent or added color, and the arithmetic backs it up: the panel's two nutrient rows total 1,880 mg against a serving weight of approximately 1.9 g.
How much sodium does a serving add?
Each serving contains 210 mg of sodium, which the panel gives as 9% of the Daily Value. The sodium is part of the sodium ascorbate molecule rather than an added ingredient, so it cannot be separated out of this particular form of vitamin C.
How many servings are in the 8 oz bottle?
About 119, according to the Supplement Facts panel. At the suggested 1/2 level teaspoon once daily, that is roughly a four-month supply.
How is this order packaged for delivery?
Every order ships in plain, unmarked outer packaging with no indication of the contents. It will not show the Gear Isle name.
