Quick Facts

Who NOW C-1000 Is For

• Adults wanting a reliable daily vitamin C at the lowest cost per gram in Canada
• People focused on daily immune support, especially during cold and flu season
• Smokers, who need significantly more vitamin C than non-smokers (research-supported)
• Anyone using vitamin C for collagen production support (skin, hair, nails, connective tissue)
• Active people supporting recovery and antioxidant balance after training
• People who want the bioflavonoid-enhanced version closer to whole-food vitamin C

Who this product is NOT for: People with kidney stones (especially calcium-oxalate type) should consult their healthcare practitioner before taking high-dose vitamin C — it can increase oxalate excretion. People with hemochromatosis should be cautious — vitamin C enhances iron absorption. If you have a sensitive stomach, buffered vitamin C or vitamin C with sodium ascorbate is gentler than pure ascorbic acid. If you want a higher-absorption form for very high daily doses (>2,000mg), look at liposomal vitamin C instead.

Vitamart's Take

NOW C-1000 is an everyday vitamin C supplement for immune and antioxidant support, providing 1,000 mg per capsule. It includes citrus bioflavonoids and rosehips, making it a more rounded option than plain vitamin C on its own. The 1,000 mg strength makes it a simple, high-potency choice for daily vitamin C support.

How NOW C-1000 Compares

NOW C-1000 vs AOR C + Bioflavonoids

Both pair vitamin C with bioflavonoids. AOR C + Bioflavonoids includes a wider spectrum of citrus bioflavonoids (narirutin, didymin, hesperidin, hesperetin) at a premium-priced point. NOW C-1000 covers the basics at significantly lower per-capsule cost. AOR is the more sophisticated formula; NOW is the workhorse daily value. Both work.

NOW C-1000 vs AOR Vitamin C 1000mg

AOR Vitamin C 1000mg is plain ascorbic acid without bioflavonoids — simplest possible formula at a moderate price. NOW C-1000 adds bioflavonoids and rosehips at a comparable per-capsule cost. NOW gives you more for similar money.

NOW C-1000 vs Liposomal Vitamin C

Liposomal vitamin C uses fat-based liposomes for higher absorption — useful at very high doses (2,000–3,000mg+) where standard vitamin C absorption plateaus. NOW C-1000 is fine for standard daily doses (1,000–2,000mg). Choose liposomal if you're specifically targeting high-dose support (recovering from illness, immune intensive care under practitioner guidance); choose NOW for everyday baseline.

NOW C-1000 vs Buffered Vitamin C

Pure ascorbic acid (like NOW C-1000) is acidic and can upset sensitive stomachs. Buffered vitamin C combines ascorbic acid with calcium, magnesium, or potassium salts to neutralize the acidity — gentler on stomachs but slightly less bang-per-mg of pure C. If you have a sensitive stomach or take vitamin C on an empty stomach, buffered is the kinder option.

Vitamin C: What It Actually Does

• Immune function. Vitamin C concentrates in immune cells and is required for their normal function. Low vitamin C is associated with increased infection susceptibility; supplementation supports cell function and may modestly reduce cold duration.
• Collagen synthesis. Vitamin C is required for the enzymatic step that converts proline into hydroxyproline — the bond that holds collagen together. Skin, blood vessels, tendons, ligaments, and bones all depend on collagen, which depends on vitamin C.
• Antioxidant action. Vitamin C neutralizes free radicals in water-based compartments of the body and helps recycle vitamin E (the fat-soluble antioxidant) — the two work as a team.
• Iron absorption. Vitamin C dramatically improves absorption of non-heme iron (the iron in plant foods and supplements). Take with iron for vegetarians or people with iron-deficiency anemia.
• Bioflavonoid synergy. Bioflavonoids extend the antioxidant action of vitamin C and may have their own benefits for capillary integrity, allergy support, and inflammation balance. They're why whole-fruit vitamin C tends to be more effective than isolated ascorbic acid in some contexts.
• Smokers need more. Smoking dramatically increases vitamin C requirements (smokers are recommended to consume 35mg more daily than non-smokers, often more from supplementation).
• Bowel tolerance ceiling. Very high doses cause loose stools — the body's signal it can't absorb more. Most people tolerate up to 2,000–3,000mg daily without issue, split into multiple doses.

How To Use

Adults: Take 1 capsule daily with food. For higher daily doses during illness or for immune intensive support, split into 2–3 doses throughout the day (vitamin C is water-soluble — splitting maintains steadier blood levels than one big dose).

Cautions: Consult your healthcare practitioner before use if you are pregnant or breastfeeding (although vitamin C is generally considered safe), have kidney stones or kidney disease, have hemochromatosis or iron overload, are scheduled for surgery, or take medication. May affect glucose meter readings; if you have diabetes and monitor blood sugar, be aware.
