NOW C-1000 RH NO TR (250 Tablets): High-Potency Vitamin C with Rose Hips & Bioflavonoids
Fast-acting antioxidant support, collagen synthesis, and everyday immune defense in an unbuffered, non-timed-release formulation.
What does "NO TR" mean? On retail product listings, "NO TR" stands for "Non-Timed Release" (standard or immediate release). Unlike sustained-release (SR) or timed-release tablets engineered with waxy coatings to dissolve gradually over several hours, this regular-release tablet dissolves promptly in the digestive tract. This provides rapid, bioavailable delivery of 1,000 mg of pure ascorbic acid right when your immune system and muscle tissues need it most.
If you are looking for an everyday immune essential that delivers high-strength ascorbic acid paired with botanical co-factors, NOW Foods C-1000 RH NO TR delivers clinical-strength nutrition without unnecessary fillers, artificial colorings, or synthetic sustained-release matrices.
The Synergistic Trio: Why Vitamin C Needs Rose Hips & Citrus Bioflavonoids
Many cheap retail supplements use plain synthetic ascorbic acid in isolation. While your body can utilize isolated ascorbic acid, nature never packages vitamin C alone. In raw citrus fruits and wild berries, vitamin C is surrounded by complementary plant compounds that protect the molecule and enhance how your tissues absorb it.
1. Pure Ascorbic Acid (1,000 mg)
The bioidentical active form of Vitamin C recognized directly by human transport proteins (SVCT1 and SVCT2). It drives essential enzymatic reactions throughout the cardiovascular, skeletal, and immune systems.
2. Rose Hips Powder (25 mg)
Derived from the fruit of wild rose bushes (Rosa canina), rose hips provide natural organic acids, pectin, and plant pigments. These compounds mimic the whole-food matrix to assist natural digestive uptake.
3. Citrus Bioflavonoids (25 mg)
Polyphenols (including hesperidin) extracted from citrus rinds. Bioflavonoids act as dedicated "bodyguards," shielding fragile ascorbic acid from premature oxidation in the gut and supporting capillary strength (Vinson & Bose, Am J Clin Nutr, 1988).
Together, this trio delivers a balanced, nature-inspired delivery model that supports cellular uptake while remaining gentle on your wallet.
Core Health Benefits: What 1,000 mg of Vitamin C Does Inside Your Body
While most people associate vitamin C exclusively with winter wellness, this water-soluble micronutrient serves as an essential cofactor in dozens of enzymatic processes every single day.
✓ 1. Essential Collagen Synthesis for Skin, Tendons, and Joint Cartilage
Collagen is the primary structural protein holding your body together. However, your body cannot knit together stable collagen strands without vitamin C. Ascorbic acid acts as the required cofactor for the enzymes prolyl hydroxylase and lysyl hydroxylase, which stabilize the triple-helix structure of collagen (Pullar et al., Nutrients, 2017). A daily intake of 1,000 mg provides the raw nutritional support needed for firm skin, resilient blood vessel walls, healthy gums, and flexible joint cartilage.
✓ 2. Robust Immune Cell Activation and Motility
During seasonal challenges or periods of physical exhaustion, your white blood cells (phagocytes and T-cells) rapidly deplete their internal vitamin C reserves. Supplementing with 1,000 mg replenishes intracellular concentrations up to 100 times higher than blood plasma levels. This fuels cell motility, helps immune cells clear out spent debris, and protects healthy tissue from collateral oxidative stress (Carr & Maggini, Nutrients, 2017).
✓ 3. Systemic Antioxidant Defense ("The Molecular Janitor")
Every breath we take, combined with sun exposure, environmental pollution, and intense physical exercise, produces unstable free radicals. Vitamin C donates electrons to neutralize these reactive molecules before they can degrade DNA, lipids, or cell membranes. Even better, vitamin C actively regenerates other spent antioxidants—such as Vitamin E—returning them to active duty.
✓ 4. Enhanced Non-Heme Iron Bioavailability
Plant-based iron from beans, grains, and leafy greens is notoriously hard for the human digestive tract to absorb. Taking vitamin C alongside meals chemically reduces ferric iron (Fe3+) into ferrous iron (Fe2+), significantly boosting intestinal absorption and helping combat everyday fatigue caused by sub-optimal iron status (National Institutes of Health ODS, 2021).

How to Take, Digestive Tolerance & Important Cautions
To maximize absorption and avoid digestive upset, practical timing and dosage awareness make all the difference.
Recommended Usage
Take 1 tablet daily, preferably with a main meal and a full 8-ounce glass of water. Taking unbuffered ascorbic acid with food helps buffer natural acidity in the stomach and promotes steady intestinal absorption.
Tolerable Limits & Safety
The Tolerable Upper Intake Level (UL) established by the National Academy of Medicine is 2,000 mg per day for healthy adults. Because vitamin C is water-soluble, excess amounts are naturally cleared through urine. Doses exceeding 2,000 mg may cause temporary loose stools or mild cramping.
Important Health Considerations & Contraindications:
Kidney Stone History: Ascorbic acid is partially metabolized into oxalates. If you have a clinical history of hyperoxaluria or calcium oxalate kidney stones, consult your nephrologist or physician before taking high-dose vitamin C.
Iron Overload Conditions: Because vitamin C significantly boosts non-heme iron absorption, individuals diagnosed with hemochromatosis or thalassemia should consult their healthcare provider prior to supplementation.
Medical Consultation: For adults only. If pregnant, nursing, taking blood-thinning medications, or receiving chemotherapy, consult your doctor before using high-potency vitamins.

Frequently Asked Questions (FAQ)
What does "C-1000 RH NO TR" mean?
"C-1000" refers to 1,000 milligrams of Vitamin C. "RH" stands for Rose Hips, and "NO TR" signifies that this tablet is Non-Timed Release (immediate/standard release). It dissolves naturally in the stomach rather than using synthetic wax binders to release slowly over 8 hours.
Should I take regular release (NO TR) or timed release (TR) vitamin C?
Regular release (NO TR) is preferred if you want rapid cellular uptake—such as during acute immune needs or right after an intense workout when oxidative stress peaks. It also eliminates the need for sustained-release excipients. Timed-release versions are generally chosen by individuals who experience acid sensitivity when absorbing high single doses.
Why are there dark speckles on my NOW C-1000 tablets?
The visible speckles are completely natural. They come directly from ground rose hips (Rosa canina) fruit powder and citrus bioflavonoid extracts blended into the formula. NOW Foods does not add artificial bleaching agents or dyes to mask these authentic botanical ingredients.
Is 1,000 mg of Vitamin C too much to take every day?
For healthy adults, 1,000 mg daily is well within safe clinical parameters. The established Tolerable Upper Intake Level (UL) is 2,000 mg per day. Since Vitamin C is water-soluble, your body uses what it needs and gently clears any excess through normal kidney filtration.
Can I take this supplement on an empty stomach?
We recommend taking it with food. Ascorbic acid is naturally tart and acidic; pairing your tablet with breakfast or lunch buffers the stomach lining and improves gastrointestinal comfort while enhancing the absorption of dietary iron from your meal.
Is NOW C-1000 RH vegan and allergen-free?
Yes. This formula is 100% vegetarian and vegan, using a plant-based tablet coating and vegetable-source magnesium stearate. It is manufactured without wheat, gluten, soy, milk, egg, fish, shellfish, or tree nut ingredients in a certified cGMP facility.
