Marine collagen peptides provide 89 g protein per 100 g. A meta-analysis of 19 RCTs (Kirmse et al., Sports Med 2024) found collagen with exercise improves lean mass, tendon structure, and 48-hour recovery. Sourced from fish skin, it suits those avoiding bovine products.
How should I track Collagen peptides, marine?
Collagen peptides, marine is high in protein. Supplement tracking comes down to two things: measuring the supplement itself and logging everything around it. For powders like Collagen peptides, marine, a kitchen scale beats a scoop — scoops typically deliver 10–20% more than the stated serving (Almiron-Roig et al., Appetite 2013, found portion errors of 50–200% for dense foods). For capsules and tablets, count-based tracking is simpler but still matters at multiple daily doses. The real tracking trap is what you mix supplements with — milk, fruit, or nut butter can turn a 30-calorie serving into a 400-calorie shake. Log each ingredient separately for an accurate total.
