How C-1000 CAPS Works in Your Body: Science-Backed Health Benefits
Vitamin C is an essential water-soluble micronutrient. Because human bodies cannot produce or store vitamin C, daily replenishment is necessary for foundational biochemical pathways:
Robust White Blood Cell & Immune Defense: Immune cells such as phagocytes and T-lymphocytes accumulate high intracellular concentrations of ascorbic acid. During periods of environmental or seasonal challenge, vitamin C supports cellular motility, helps white blood cells neutralize invading microbes, and shields delicate immune tissues from oxidative breakdown (Carr & Maggini, Nutrients, 2017).
Collagen Synthesis for Skin, Gums, and Joints: Vitamin C is an indispensable co-factor for the enzymes prolyl hydroxylase and lysyl hydroxylase. These enzymes cross-link and stabilize the structural triple-helix collagen fibers that make up your skin, cartilage, ligaments, tendons, and blood vessels (Pullar et al., Nutrients, 2017).
Botanical Synergy with Bioflavonoids & Rutin: In whole citrus fruits, vitamin C naturally occurs alongside polyphenol bioflavonoids. Citrus bioflavonoids and rutin (derived from Sophora japonica flower buds) act as botanical guardians, helping stabilize ascorbic acid, reducing premature oxidative degradation, and supporting strong capillary integrity (Vlachojannis et al., Phytother Res, 2011).
Enhanced Non-Heme Iron Absorption: Taking vitamin C alongside meals converts dietary plant-based iron from its insoluble ferric state into an easily absorbable ferrous form in the duodenum, significantly boosting iron uptake for individuals following plant-focused diets (Lynch & Cook, Ann NY Acad Sci, 1980).
Cellular Antioxidant Defense: Normal metabolic processes, intense exercise, and daily exposure to environmental pollutants generate free radicals (unstable oxygen molecules). Vitamin C donates electrons to neutralize these compounds and helps regenerate other protective antioxidants in the body, such as Vitamin E.

Behind the Bottle: NOW Brand Lab Testing & Contaminant Standards
Not all vitamin supplements are manufactured with equal diligence. NOW Foods maintains one of the most advanced quality assurance infrastructures in the natural products industry, operating private, state-of-the-art analytical testing facilities that protect consumers against contaminated or sub-potent products:
NOW’s analytical and microbiological laboratories are formally accredited by the American Association for Laboratory Accreditation (A2LA). This certification proves that testing methodologies, technical competency, and equipment calibrations meet the exact standards expected of reference laboratories.
2. 31,000+ Quality Tests and Analyses Conducted Monthly
From incoming raw materials to final encapsulated lots, NOW performs over 31,000 comprehensive assays every single month, verifying ingredient identity, testing active strength, and ensuring formula stability through the expiration date.
3. ICP-MS Heavy Metal Testing (Parts-Per-Billion Sensitivity)
Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), NOW screens raw ingredients and finished capsules for toxic heavy metals—including lead, arsenic, cadmium, and mercury—down to parts-per-billion (ppb) detection thresholds. Testing limits strictly comply with California Proposition 65 and USP standards.
4. Comprehensive Pesticide & Pathogen Screening
Because C-1000 CAPS contains plant extracts (citrus bioflavonoids and sophora flower buds), NOW utilizes Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography (LC-MS) to screen for more than 500 pesticide residues. Polymerase Chain Reaction (PCR) DNA technology screens every batch for microbial pathogens, including Salmonella, E. coli, and Staphylococcus.
5. Recognized Industry Leadership
NOW was awarded the prestigious NutraIngredients-USA Editors Award for Industry Initiative of the Year after conducting independent testing campaigns that exposed fraudulent, adulterated, and severely under-dosed supplements sold by unauthorized third-party marketplace sellers.
How to Take NOW C-1000 CAPS: Dosage, Digestive Tips & Safety Guidance
Taking high-potency vitamins properly maximizes absorption while keeping your stomach comfortable. Here is practical advice based on clinical pharmacokinetics:
Suggested Daily Use:
Take 1 capsule daily, accompanied by a meal and a full glass of water.
Why Take Vitamin C With Food?
Ascorbic acid has a naturally mildly acidic pH. Consuming your capsule alongside dietary fats and proteins buffers stomach acid, prevents minor heartburn, and slows gastrointestinal transit time so your intestinal transport proteins (SVCT-1) can steadily absorb the nutrient.
Ascorbic Acid vs. Buffered Forms:
Pure ascorbic acid (found in this formula) is the exact form found in fresh fruits and is easily utilized by healthy digestive systems. However, individuals with severe gastric sensitivity, gastritis, or active acid reflux may prefer mineral-buffered forms (such as calcium ascorbate).
Safety, Tolerability & Upper Limits:
The National Institutes of Health (NIH) Office of Dietary Supplements sets the Tolerable Upper Intake Level (UL) for adults at 2,000 mg per day. Single doses higher than 2,000 mg can cause unabsorbed ascorbic acid to pull water into the bowel, leading to temporary loose stools. The 1,000 mg dose in this capsule sits safely within recommended clinical tolerances.
Precautions & Interactions:
For adults only. Consult your physician before using this product if you are pregnant, nursing, taking prescription medications (especially blood thinners, as rutin can affect capillary tone), or have a medical history of calcium-oxalate kidney stones or iron overload syndromes (hemochromatosis). Keep out of reach of children. Store in a cool, dry place after opening.

Frequently Asked Questions About NOW C-1000 CAPS
Why are Citrus Bioflavonoids and Rutin included with Vitamin C in this capsule?
In nature, citrus fruits pair ascorbic acid with botanical bioflavonoids and rutin. These phytonutrients help protect vitamin C from oxidizing before your body can absorb it, assist in recycling active antioxidants inside your cells, and provide natural support for healthy capillary strength.
What is the difference between NOW C-1000 Veg Capsules and buffered vitamin C?
NOW C-1000 CAPS delivers unbuffered ascorbic acid, matching the natural organic acid form found in citrus fruit. Buffered vitamin C chemically combines ascorbic acid with mineral carbonates (like calcium or magnesium) to reduce acidity. While most adults digest ascorbic acid with food without issue, buffered vitamin C is generally reserved for people with severe gastric ulcers or acid intolerance.
How long will one 500-capsule bottle last?
At the standard serving size of one capsule per day, a single 500-count bottle provides a full 500-day supply (over 16 months of continuous daily supplementation), offering exceptional value for individuals and families.
How does NOW test this product for lead and heavy metals?
NOW tests raw ingredients and finished lots using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) inside their ISO/IEC 17025 accredited laboratories. This equipment detects trace heavy metals down to parts-per-billion levels, confirming compliance with strict USP and California Proposition 65 safety parameters.
Can I open the capsule and mix the powder into juice or a smoothie?
Yes. The vegetarian hypromellose capsule can be gently twisted open and the contents stirred into water, fresh orange juice, or a cold smoothie. Avoid blending into hot liquids, as prolonged high heat can degrade active ascorbic acid.
What return policy applies to this purchase?
VitaNet backs this product with an unconditional 100% money-back guarantee[cite: 1]. If you are unsatisfied for any reason, we refund your purchase and pay the return shipping costs, whether the bottle is opened or unopened[cite: 1].
