Frequently Asked Questions About Hi-Tech Vitamin C
-
Why does Vitamin C absorption matter so much?
Standard ascorbic acid tablets are water-soluble and absorbed through the gut relatively quickly — but absorption efficiency decreases significantly at higher doses. At 1,000mg, a meaningful portion of a standard tablet passes through unabsorbed. Cyclosome® Technology uses a liposomal encapsulation approach that protects Vitamin C through early digestion and improves how much of the dose actually reaches circulation — relevant at the 1,000mg level that most people supplement at.† -
What do citrus bioflavonoids do alongside Vitamin C?
Citrus bioflavonoids are naturally occurring plant compounds found alongside Vitamin C in whole citrus fruits. Research suggests they enhance Vitamin C's antioxidant activity and may improve its absorption and retention in the body. Including 25mg of citrus bioflavonoids alongside 1,000mg of Vitamin C more closely mirrors how Vitamin C is found in whole food sources compared to isolated ascorbic acid alone.† -
How much Vitamin C do active people actually need?
The RDA for Vitamin C is 90mg for adult men and 75mg for adult women — but these are minimums to prevent deficiency, not necessarily optimal amounts for athletes and active individuals. Intense exercise increases oxidative stress and free radical production, which raises the body's demand for antioxidants including Vitamin C. Many sports nutrition researchers and practitioners recommend 500–1,000mg daily for regularly training individuals as part of a complete antioxidant strategy.† -
Can I take Vitamin C with other Hi-Tech wellness supplements?
Yes — Vitamin C stacks naturally with the rest of Hi-Tech's immunity stack including Zinc Lozenges, Black Elderberry, and Echinacea. It is also included in the Revive MD Essential Vitamins Pack — if you are already taking that product check the label before adding standalone Vitamin C to avoid unnecessarily high doses.† -
Is taking 1,000mg of Vitamin C per day safe?
Yes — the Tolerable Upper Intake Level for Vitamin C is 2,000mg per day for adults. 1,000mg daily is well within the established safe range for healthy adults. The most common side effect of very high dose Vitamin C is loose stools — if this occurs simply reduce the dose. Vitamin C is water-soluble meaning the body excretes what it does not use, making toxicity at standard doses extremely unlikely.†
