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

Pros

✓Nail strength and growth is the most consistently reported benefit, often noticed within 2–4 weeks

✓Well-formulated with bioavailable forms (zinc citrate, copper bisglycinate) and collagen co-factors (L-lysine, L-proline, vitamin C)
✓Vegan-friendly with a clean ingredient profile and no artificial sweeteners, salt, or starch

Cons

✗Tablets are notably large and can be difficult to swallow — a frequent complaint across platforms
✗Skin benefits are the least dramatic and slowest to materialise compared to nails and hair
✗No third-party testing or certification (e.g. Informed Sport, NSF) disclosed
✗Zinc content (15mg at 150% NRV) may cause mild nausea if taken on an empty stomach

Best For
