Liposomal Vitamin C by Quicksilver Scientific

If you struggle with fruit-and-vegetable intake, train hard, or your plasma vitamin C has tested low, liposomal vitamin C is a practical way to replete without stomach upset. Smokers and secondhand smoke–exposed adults burn through vitamin C faster. It also pairs well with oral iron when Ferritin (your iron storage marker) is low, since vitamin C improves iron absorption. For skin or post-procedure collagen needs, steady daily dosing is more useful than occasional megadoses.

This formula uses sodium ascorbate (a buffered form of vitamin C) inside tiny lipid spheres called liposomes that enhance absorption through the mouth and gut. Vitamin C donates electrons to neutralize free radicals, regenerates vitamin E, and is required for collagen cross-linking, which shows up in skin, tendons, and wound healing. It also supports immune cell function and modestly lowers histamine (a signaling molecule behind congestion) during infections, though it won’t prevent colds outright.

Each teaspoon provides 1,000 mg. Follow the label: take it by mouth, hold for 30 seconds, then swallow on an empty stomach at least 10 minutes before meals. Most adults use 500–1,000 mg once or twice daily; during acute stress or travel, some split into 2–3 doses. If you’re taking iron for low Ferritin, take them together. Loose stools or gas usually mean you’ve exceeded your personal tolerance—reduce the dose.

If you have a history of calcium oxalate kidney stones, advanced kidney disease, or iron overload conditions (like hemochromatosis), avoid high-dose vitamin C unless your clinician is monitoring labs such as Ferritin and creatinine. High intakes can skew some home glucose meters and fecal occult blood tests; time your dose away from testing days. Oncology patients should clear any antioxidant, including vitamin C, with their care team. Each teaspoon contains 125 mg sodium, relevant if you’re on a strict low-sodium diet.
