Advanced Hydrolysed Marine Liqui...

Pros

✓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

What does the data say about Advanced Hydrolysed Ma... vs Collagen Boosting Beau...?

Known Nutrition's Advanced Hydrolysed Marine Liquid Collagen Couples Supply (£64.99, 82/100) and Bioglan Superfoods' Collagen Boosting Beauty Protein (£16.99, 70/100) take fundamentally different approaches. The Known Nutrition option delivers 5000mg of hydrolysed marine collagen in liquid form with claimed liposomal delivery for absorption, while Bioglan's powder contains 75.3g of plant-based protein from pea and rice sources. One is direct collagen; the other supports your body's natural collagen production through amino acids.

The Known Nutrition product suits people seeking fast results — reviewers report skin plumpness and reduced fine lines within four weeks, particularly benefiting perimenopausal women experiencing hair thinning. It's ideal if you struggle with capsules. Bioglan suits vegans, vegetarians, or anyone wanting complete protein with beauty nutrients on a budget. At £16.99, it costs roughly a quarter of Known Nutrition's price.

Known Nutrition's redesigned sachet format has frustrated customers with leaking and difficulty emptying. Bioglan's powder mixes easily and tastes pleasant, though it's labeled non-vegan despite being plant-based. Only Known Nutrition carries third-party testing verification.

Advanced Hydrolysed Marine Liquid Collagen Couples Supply (2x 28-Day Supply) Winner 82/100

Known Nutrition's Advanced Marine Liquid Collagen delivers 5000mg of hydrolysed marine collagen per 15ml sachet, enhanced with liposomal technology, Vitamin C, pine bark extract, and bilberry.
