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

✓Vegan, free from gluten, dairy, soya, sugar, and starch — broad dietary compatibility

Cons

✗Results require patience — noticeable improvements typically take 4–8 weeks of consistent use
✗L-proline and L-lysine doses (50mg each) are modest compared to standalone collagen peptide formulas
✗Not third-party tested — no independent certification for purity or label accuracy

What does the data say about Advanced Hydrolysed Ma... vs Skin, Nails and Hair F...?

Known Nutrition's marine collagen liquid costs £64.99 for two 28-day supplies against Solgar's £13.90 tablets. The liquid delivers 5000mg hydrolysed collagen with claimed liposomal absorption, producing visible skin plumping and fine lines reduction within four weeks. Solgar takes a different route: zinc citrate, copper bisglycinate, and 1000mg MSM targeting nail and hair growth, with faster, stronger nails as the key result. On effectiveness both score high (83 and 82), though Solgar's ingredient quality edges ahead at 85 versus 83.

Choose the liquid if you want rapid visible skin improvements and manage the redesigned sachet format — users report it leaks and doesn't empty fully. Pick the tablets for nail strength, expecting results after 4–8 weeks with notably large pills. At nearly five times the price, Known Nutrition justifies itself only if fast skin results matter. Solgar under £14 delivers genuine benefits if you're patient and okay with larger tablets.
