Vitamin World Timed Release C-1000 mg
Brand: Vitamin World · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that Vitamin World Timed Release C-1000 mg provides a high dose of vitamin C in a formulation designed for gradual absorption. This is a reasonable choice for supporting immune function, but the data provided does not include any clinical studies or specific efficacy outcomes for this exact product. Data not available on clinical trials for this specific formulation.
How it works
Vitamin C acts as a powerful antioxidant that helps protect your cells from damage caused by free radicals. It also plays a key role in supporting your immune system and is necessary for the production of collagen, which is important for skin and joint health [NIH ODS]. The "timed release" design is meant to deliver the vitamin C steadily over several hours, which may help maintain consistent blood levels compared to a single large dose.
Safety profile
FDA received 694 adverse event reports for vitamin C products. Side effects can include gastrointestinal discomfort, diarrhea, and nausea, especially at high doses [FDA data]. Because this product provides 1,000 mg, which is above the Tolerable Upper Intake Level of 2,000 mg daily for adults, you should be cautious about taking additional vitamin C from other supplements or foods [NIH ODS].
Our recommendation
For most adults, a daily intake of 75-90 mg of vitamin C is sufficient through diet, and 1,000 mg is a high supplemental dose [NIH ODS]. If you choose to use this product, start with one tablet daily and monitor for any digestive upset. Data not available on long-term safety or interactions with medications for this specific product.
