Excerpt: We were curious about THORNE Vitamin C’s promise as an immune and collagen booster, so we pitted it against natural oranges. While oranges are a whole-food powerhouse, this supplement blends high-quality Vitamin C with citrus bioflavonoids from oranges, offering a potent dual action. Our test revealed balanced support for cellular energy production and tissue health, with its gluten-free capsules making it a convenient daily choice. Unlike raw oranges, THORNE’s formula ensures sustained absorption, though we wish it matched the natural glow oranges provide. The 90-capsule count gives us a decent supply for monitoring, and the citrus bioflavonoids complement the Vitamin C without overpowering it. A reliable pick for those seeking targeted immunity and collagen support—just don’t expect beach vibes from a bottle.
