Key Benefits of Vitamin C Supplementation
Discover Source Naturals Systemic — Vitamin C is well known for helping to maintain a healthy immune system.* It supports the production and function of white blood cells, which are essential for defending the body.* As a powerful antioxidant, it helps neutralize free radicals—unstable molecules that can cause cellular damage and contribute to premature aging.*
Beyond immune support, vitamin C is required for the synthesis of collagen, a protein necessary for healthy skin, blood vessels, tendons, and bones.* It also enhances the absorption of non-heme iron from plant-based foods, making it a valuable nutrient for those on vegetarian or vegan diets.* Many people turn to vitamin C as a cornerstone of their daily wellness routine, particularly during cold and flu season.
What Is Systemic C and How Does It Work?
Source Naturals Systemic C is a high-potency vitamin C supplement designed to deliver 1000 mg of ascorbic acid per tablet. Unlike standard vitamin C, this formulation is created with a focus on systemic availability, meaning it is designed to help support the body's natural distribution and utilisation of this essential nutrient.* After vitamin C performs its antioxidant function by neutralizing free radicals, it becomes oxidized and is No longer active. Systemic C is formulated to help maintain a steady supply of active vitamin C in the body, supporting immune function and free radical scavenging throughout the day.*
Vitamin C is a water-soluble nutrient that must be replenished daily through diet or supplementation. It plays a vital role in numerous physiological processes, including collagen synthesis and neurotransmitter production. With 1000 mg per tablet, Systemic C offers a convenient way to meet higher daily requirements, especially during times of increased oxidative stress or immune demand.*
What Makes Systemic C Special?
Systemic C is not just another vitamin C supplement; it is designed with a unique approach to bioavailability. The term “systemic” refers to the formula’s aim to help support the body’s natural processes for distributing vitamin C to tissues and cells. After vitamin C performs its antioxidant duties, it becomes oxidized and spent. Systemic C is designed to help replenish and maintain active vitamin C levels, ensuring that a steady supply is available when needed.*

Types of Vitamin C Supplements
Vitamin C supplements come in various forms, including ascorbic acid, buffered mineral ascorbates (such as sodium ascorbate or calcium ascorbate), liposomal vitamin C, and whole-food sources like acerola cherry or camu camu. Ascorbic acid is the most common and most cost-effective form, offering excellent potency in a compact tablet. Systemic C uses pure ascorbic acid, providing 1000 mg per tablet for those seeking high-dose convenience.
Buffered forms are often recommended for individuals with sensitive stomachs, as they are less acidic. Liposomal vitamin C is said to have enhanced absorption, but traditionally delivered ascorbic acid like Systemic C is well-absorbed when taken with food. Whole-food sources provide additional phytonutrients, but the potency per serving is usually lower. Choosing the right form depends on your individual needs, tolerance, and lifestyle.
How to Choose the Best Vitamin C Supplement
When selecting a vitamin C supplement, consider the dosage, form, purity, and manufacturing standards. Systemic C offers a high dose of 1000 mg per tablet, ideal for those who require greater amounts for immune support or antioxidant protection. The tablets are free from common allergens and artificial additives, ensuring a clean product. Also, look for brands with a long history of quality, such as Source Naturals, which has been providing supplements since 1982 and adheres to cGMP standards.
If you have a sensitive stomach, you may want to start with a lower dose or take the tablet with food. For those on a budget, ascorbic acid tablets like Systemic C offer excellent value without compromising on potency. Always check the label for third-party testing certifications and avoid products with unnecessary fillers or binders.
Recommended Dosage and Safety
The suggested use for Source Naturals Systemic C is one tablet one to two times daily. Each tablet provides 1000 mg of vitamin C (as ascorbic acid). Do not exceed the recommended serving size unless advised by a healthcare professional. Some individuals may experience gastrointestinal discomfort, including diarrhea or upset stomach, when taking high doses of vitamin C. It is generally recommended to start with a lower dose and gradually increase as tolerated.
Vitamin C is water-soluble, meaning excess amounts are excreted in urine. However, taking more than 2000 mg daily may increase the risk of kidney stones in susceptible individuals. If you have a history of kidney stones, consult your physician before supplementing with high-dose vitamin C. As with any supplement, it is advisable to speak with a healthcare provider before starting a new regimen, especially if you are pregnant, nursing, or taking medication. Keep out of reach of children.
