Known Nutrition Marine Liquid Collagen vs Shivay Herbals Marine Collagen: What Does the Data Say?

Advanced Hydrolysed Marine Liquid Collagen Couples Supply delivers 5000mg hydrolysed marine collagen per serving in liquid form with claimed liposomal delivery. Marine Collagen Complex with Vitamin C, Hyaluronic Acid, Biotin packs 1000mg hydrolysed Type I marine collagen into capsules plus Vitamin C, Hyaluronic Acid and Biotin. The liquid version scores 82/100 overall and 83/100 on effectiveness while the capsule one hits 70/100 overall and 65/100 on effectiveness. Ingredient quality follows the same pattern at 83/100 versus 70/100. Value flips the script with the capsules winning at 91/100 against 69/100 for the liquid.

People who prefer liquids and want higher doses should grab the Advanced Hydrolysed Marine Liquid Collagen Couples Supply at £64.99 especially if they seek skin plumpness and fine line reduction within four weeks or notice hair thinning improvements. Those on tight budgets who hate any taste or smell and just need an easy daily habit will find the Marine Collagen Complex with Vitamin C, Hyaluronic Acid, Biotin at £9.99 for 60 days far more practical. Capsule swallowers avoid the hassle of sachets while liquid fans dodge large pills.

Practical issues matter too. The liquid sachets often leak and prove tricky to empty completely which annoyed several users enough for one-star reviews. Capsules carry no taste or aftertaste yet some reviewers call them notably large and hard to swallow. The liquid format suits anyone who struggles with pills. Both products target skin hair and nails support but differ sharply in daily experience and cost.

Advanced Hydrolysed Marine Liqui...

Pros

  • 5000mg hydrolysed marine collagen at a clinically relevant dose, with liposomal delivery claimed to enhance absorption
  • Strong positive feedback on skin plumpness, fine line reduction, and hydration — multiple reviewers report results within 4 weeks
  • Hair thinning and dullness improvements noted, particularly by perimenopausal users
  • Synergistic formula: Vitamin C (cofactor for collagen synthesis), pine bark extract (antioxidant), bilberry, Vitamin E, and A

Cons

  • Redesigned sachet format widely criticised: leaking, difficult to fully empty, and inconvenient — drove two 1-star reviews from previously loyal customers
  • Price has increased while some reviewers feel pack size has decreased, reducing perceived value
  • One reviewer found the taste artificial; subjective but relevant given the liquid format
  • Short-term users (under 1 week) report no results yet, which is expected but may disappoint those seeking rapid outcomes

Best For

Women over 40 or in perimenopause seeking skin and hair support Those who struggle to swallow capsules and prefer a liquid format Couples or household members sharing a monthly supply Consumers prioritising certified, UK-manufactured supplements Anyone wanting a collagen product with supporting antioxidant co-factors built in

Marine Collagen Complex with Vit...

Pros

  • Exceptional value — approximately £9.99 for a 60-day supply works out to around £5 per month, significantly cheaper than collagen liquids and powders
  • No taste or aftertaste reported across all reviewers, making daily compliance straightforward for those sensitive to collagen flavour or odour
  • Well-rounded formula: hydrolysed Type I marine collagen combined with Vitamin C (EFSA-approved collagen-formation claim), Hyaluronic Acid, and Biotin
  • Made in the UK under GMP standards, free from GMOs and artificial colours — reassurance of basic quality control

Cons

  • 1,000mg daily dose is at the low end of the therapeutic range — clinical research on skin and joint outcomes typically uses 2.5–10g per day; powder alternatives commonly deliver 5–10g per serving
  • Capsules described as notably large by multiple reviewers — may be a challenge for those with swallowing difficulties
  • No independent third-party testing (e.g. Informed Sport, NSF, Labdoor) — quality assurance relies solely on the manufacturer's own GMP declaration
  • Not suitable for vegetarians, vegans, or those with fish allergies — contains fish-derived collagen

Best For

Budget-conscious shoppers seeking an affordable daily collagen habit People who dislike the taste, smell, or texture of collagen powders and liquids Women over 30 noticing early signs of collagen decline — fine lines, brittle nails, hair thinning Collagen beginners wanting a low-cost, low-commitment entry point before investing in higher-dose formats UK consumers who prefer domestically manufactured supplements with clear ingredient labelling
