Shivay Herbals Marine Collagen vs Known Nutrition Clear Skin

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

Pros

• ✓Most reviewers report clearer, less oily skin with regular use
• ✓Strong certifications: ISO independently tested, GMP, BRC — rare combination for gummy supplements
• ✓Zinc Citrate and Selenium Yeast are well-absorbed, evidence-backed forms for skin health
• ✓Contains probiotic (Bacillus coagulans) and prebiotic (inulin) for gut-skin axis support

Cons

• ✗Evening Primrose Oil at 60mg is far below the 500–3000mg range used in clinical studies — likely token dosing
• ✗Inulin at 50mg is negligible as a prebiotic (effective doses start at 5g); Bacillus coagulans at 250M CFU is low-end
• ✗At least one user reported a strong sulfurous/rotten-egg taste, possibly from selenium yeast
• ✗Not suitable for vegans (contains milk via lactic acid); glucose syrup and sucrose are the first two ingredients
