It stimulates white blood cell production and function, which are crucial for fighting infections, and protects immune cells from oxidative stress thanks to its antioxidant properties. As a required cofactor for collagen synthesis, vitamin C helps maintain healthy skin, supports wound healing, and keeps blood vessels, bones, and cartilage in good shape. Additionally, it contributes to the maintenance of normal bones and teeth by aiding in collagen matrix formation, and it neutralizes free radicals to support overall cellular health.\u003c\/p\u003e\u003ch2\u003eTypes of Vitamin C Supplements\u003c\/h2\u003e\u003cp\u003eWhen it comes to vitamin C supplements, you have choices: ascorbic acid (the most common and budget-friendly), sodium ascorbate (a buffered version that’s easier on the stomach), and liposomal vitamin C (encapsulated for better absorption). Some products also add bioflavonoids, naturally occurring plant compounds that may work synergistically with vitamin C. GNC’s formula uses ascorbic acid as the active ingredient, and it includes citrus bioflavonoids derived from lemon and orange peels for a comprehensive antioxidant profile. The capsules are vegetarian-friendly and free from sugar, starch, artificial colours, artificial flavours, sodium, wheat, gluten, corn, dairy, and soy—perfect for those with dietary restrictions.\u003c\/p\u003e\u003ch2\u003eHow to Choose the Best Vitamin C Supplement\u003c\/h2\u003e\u003cp\u003eWhen picking a vitamin C supplement, consider the dosage, form, and any extra ingredients. A typical serving is between 500 mg and 1,000 mg, depending on your needs. Tablets, capsules, powders, and gummies each offer different convenience and absorption rates. If you have a sensitive stomach, a buffered form like sodium ascorbate might be better. Look for products with third party testing or quality seals. GNC, with over 85 years of experience, manufactures this supplement in facilities with strict quality standards. The citrus bioflavonoids are a plus, as they may enhance bioavailability. And if you have sensitivities, this product is allergen-friendly—no common allergens or artificial additives.\u003c\/p\u003e\u003ch2\u003eWhat Is Vitamin C and Why Do You Need It?\u003c\/h2\u003e\u003cp\u003eVitamin C (ascorbic acid) is a water-soluble vitamin essential for many bodily functions. Since your body can’t make it, you have to get it from your diet or supplements. It’s famous for immune support, acting as a potent antioxidant that shields cells from free radical damage. It’s also necessary for collagen synthesis, a protein that gives structure to skin, blood vessels, tendons, and bones. Without enough vitamin C, your body can’t repair tissues properly or keep bones and teeth strong. This GNC supplement delivers 1,000 mg of vitamin C per capsule, paired with citrus bioflavonoids—plant compounds that may help with absorption and antioxidant activity. Whether for daily wellness or seasonal immune support, vitamin C is fundamental.\u003c\/p\u003e\u003ch2\u003eRecommended Dosage and Safety\u003c\/h2\u003e\u003cp\u003eTake one capsule daily for 1,000 mg of vitamin C. Since it’s water-soluble, any extra is usually flushed out in urine, but doses over 2,000 mg per day can cause digestive upset in some people. Always follow the label and check with a health-care professional before starting a new supplement, especially if you are pregnant, nursing, on medication, or have a medical condition. This product is for adults. Store in a cool, dry place out of reach of children.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eCan I take this vitamin C supplement on an empty stomach?\u003c\/strong\u003e It’s usually fine, but some may get mild stomach upset.
