NOW Foods Vitamin C-1000 with Ro...

Pros

✓Excellent value — 250 tablets provides 8+ months of daily supply at a budget-friendly price
✓Bioflavonoid complex (100 mg) and rutin support vitamin C bioavailability and vascular health
✓Well tolerated — majority of reviewers report no GI irritation when taken with food
✓Strong brand credibility: GMP certified, Non-GMO, Vegan, Kosher, third-party tested

Cons

✗Tablets are notably large — some reviewers mention this as an inconvenience, with a few resorting to chewing
✗Standard ascorbic acid form — some users prefer buffered (e.g. calcium ascorbate) or liposomal vitamin C for higher-dose tolerance
✗Rose hips and acerola are present in small amounts (25 mg and 10 mg respectively) — more symbolic than therapeutically significant
✗Can cause loose stools or mild GI discomfort if taken in multiple high doses or on an empty stomach

Best For

Daily immune maintenance users Athletes seeking antioxidant and recovery support Budget-conscious supplement buyers Vegans and those with multiple allergen sensitivities People taking iron supplements (vitamin C enhances non-heme iron absorption) Over-40s focused on collagen and vascular health

CollagenUP®, Hydrolysed Marine C...

Pros

✓Clean minimal formula — hydrolysed marine collagen, hyaluronic acid, and vitamin C with no fillers or unnecessary additives
✓Strong pattern of skin and nail improvements in reviews, typically noticed within 2–4 weeks of daily use
✓Dissolves easily and blends into coffee, miso soup, or juice without significantly altering flavour
✓464g container offers good value per serving; multiple reviewers buy the larger size specifically for economy

Cons

✗5g collagen per scoop is on the lower end; clinical studies for joint and cartilage benefits typically use 10–15g daily
✗Noticeable fishy smell and taste in cold or plain water — several reviewers recommend mixing with juice or warm drinks
✗Vitamin C and hyaluronic acid doses are not disclosed, making it impossible to assess whether they reach clinically relevant levels
✗No third-party testing verified per product specs

Best For

People prioritising skin hydration and elasticity who want a clean, additive-free collagen powder Those avoiding bovine collagen due to dietary, religious, or personal preference for fish-sourced products Regular collagen users buying in bulk for family use or long-term supplementation

What does the data say about NOW Foods Vitamin C-10... vs CollagenUP®, Hydrolyse...?

These two products share vitamin C as an ingredient but serve entirely different purposes. NOW Foods Vitamin C-1000 is a straight supplement — 1000mg ascorbic acid per tablet, plus a 100mg bioflavonoid complex and rutin to support absorption and vascular health. CollagenUP, by contrast, uses vitamin C as a supporting ingredient alongside hydrolysed marine collagen peptides and hyaluronic acid, targeting skin and nail health rather than immune support specifically. The dosing gap matters too: CollagenUP provides only 5g of collagen per scoop, which is below the 10–15g range used in clinical studies for joint benefits, according to the product data.

On scores, NOW Foods wins across every category — 83/100 overall versus 73/100, with a value score of 92/100 against CollagenUP's 82/100. At £24.99 for 250 tablets, that works out to over eight months of daily use, which is genuinely difficult to beat. CollagenUP at £33.84 offers a clean, additive-free formula with no fillers, and reviewers report visible skin and nail improvements within two to four weeks — but the lower overall score of 73/100 reflects limitations in effectiveness and ingredient quality relative to price.

Practically speaking, the NOW Foods tablets are on the large side, and some users find them awkward to swallow. CollagenUP dissolves well in hot drinks like coffee or miso soup, but in cold or plain water the fishy smell and taste are noticeable enough that several reviewers specifically recommend mixing it with juice. If your goal is daily immune maintenance or antioxidant support on a tight budget, NOW Foods is the clear pick. If you want a collagen-focused powder that also delivers vitamin C, and you're comfortable mixing it into a warm drink each morning, CollagenUP fills that gap — though athletes seeking recovery support would be better served by the NOW Foods option.

NOW Foods Vitamin C-1000 with Rose Hips & Bioflavonoids - 250 Tablets Winner 83.0/100

NOW Foods Vitamin C-1000 is a well-regarded daily immune support supplement delivering 1,000 mg of ascorbic acid per tablet, enhanced with 100 mg of citrus bioflavonoids, rose hips, rutin, and acerola — a formula reviewers consistently praise for immune resilience, antioxidant support, and collagen-related skin benefits.
