Kiki Health offers two distinct references. Pure Marine Collagen is a single-spectrum type I collagen, optimised for skin and joints with maximum purity and a concentrated amino acid profile (hydroxyproline, glycine, proline). The Beauty Marine Collagen Blend is an enriched formula adding vitamin C, hyaluronic acid and other beauty actives. Pure Marine Collagen is ideal for those wanting a clean, dosable base to integrate into their own nutritional stack.
Kiki Health collagen peptides have undergone enzymatic hydrolysis reducing their molecular weight to under 2,000 Daltons. At this size, their bioavailability exceeds 90% according to pharmacokinetic studies, compared to under 5% for non-hydrolysed collagen. This is the difference between an active supplement and an ordinary protein powder.
For skin-specific benefits, yes. Marine collagen is primarily type I, the dominant type in skin (80% of cutaneous collagen). Its molecular structure is closer to human collagen than bovine. Comparative studies show marine peptides have greater skin biocompatibility. Bovine collagen better covers types I AND III, making it more relevant for joints and tendons. Choose based on your objective.
The clinically validated effective dose is 5 to 10 grams of collagen peptides per day. A dose of 10 grams (two level tablespoons) in your morning drink constitutes the optimal protocol for combined skin and joint action.
Yes. Hydrolysed collagen peptides are thermostable. You can incorporate it into your coffee, hot tea, soup or porridge without losing efficacy. The powder dissolves perfectly when hot and remains completely neutral in taste.
For skin: an 8-week study showed a 20% reduction in fine lines and a 12% increase in skin hydration. First effects (radiance, hydration) are visible from 3 to 4 weeks. For joints, studies use periods of 12 to 24 weeks. Daily consistency is non-negotiable.
No. Marine collagen is extracted from fish skins and scales, making it formally contraindicated for people with fish allergies. In this case, Kiki Health Bovine Collagen is the alternative.
Pure marine collagen is generally very well tolerated. Pregnant women may consume it, but should check the label to ensure the formula contains no additional contraindicated actives. If following a high-protein diet, integrate the collagen into your daily protein intake.
