Source Naturals Systemic C, 500 mg – 240 Tablets

Vitamin C is a vital nutrient that your body cannot store, so regular intake is essential. Source Naturals Systemic C offers a carefully formulated 500 mg tablet to help maintain your daily levels. With 240 tablets per bottle, this supplement provides a convenient way to support your immune system and overall wellbeing.*

Key Benefits of Vitamin C

Vitamin C is best known for its ability to support the immune system. Adequate intake helps maintain the body’s natural defences, and as an antioxidant, it neutralises free radicals that can cause cellular damage and premature ageing.* Beyond immune and antioxidant support, vitamin C is involved in collagen synthesis—a protein essential for skin elasticity, wound healing, and strong blood vessels.* It also enhances absorption of non-heme iron from plant foods, making it valuable for vegetarians and vegans.

Types of Vitamin C Supplements

Vitamin C supplements come in various forms: ascorbic acid, sodium ascorbate, calcium ascorbate, and liposomal vitamin C. Ascorbic acid is the most common but can be acidic, causing digestive discomfort in sensitive individuals. Buffered forms like calcium ascorbate and magnesium ascorbate are less acidic and better tolerated.

Systemic C from Source Naturals combines ascorbic acid with mineral ascorbates and bioflavonoids, offering a balanced approach. Bioflavonoids, such as hesperidin and rutin, are plant compounds that work synergistically with vitamin C to support capillary health and antioxidant activity.*

What Makes Systemic C Different?

Many vitamin C supplements simply provide ascorbic acid, but Source Naturals Systemic C is designed to make more vitamin C available for your body. The formula includes a blend of mineral ascorbates and bioflavonoids, naturally occurring compounds that may support vitamin C utilisation.* This thoughtful formulation aims to optimise delivery and activity, setting it apart from standard supplements.

Each tablet provides 500 mg of vitamin C from calcium ascorbate, magnesium ascorbate, and ascorbic acid. This buffered form is gentler on the stomach than straight ascorbic acid, whilst delivering potent antioxidant support.

How to Choose the Best Vitamin C Supplement

When selecting a vitamin C supplement, consider dosage, form, and additional ingredients. A 500 mg dose is a common starting point for daily maintenance, with higher doses used during times of immune stress. For a sensitive stomach, a buffered form like Systemic C is a better choice than plain ascorbic acid.

Quality matters: look for supplements made in facilities following Good Manufacturing Practises (cGMP) and check for third-party testing. Source Naturals has been a trusted brand for over 40 years, manufacturing in the USA under strict quality standards. Systemic C is free from yeast, dairy, egg, gluten, soy, wheat, preservatives, and artificial colours, flavours, or fragrances.

Recommended Dosage and Safety

The suggested use for Source Naturals Systemic C is 2 tablets once or twice daily, providing 1000 mg to 2000 mg of vitamin C per day. Start with the lower dose to assess tolerance. Vitamin C is water-soluble, so excess is typically excreted, but very high doses (above 2000 mg per day) may cause digestive upset in some individuals.

As with any supplement, consult your health care provider before use, especially if you are pregnant, nursing, have a medical condition, or are taking medication. Store in a cool, dry place away from direct sunlight.
