How these numbers are read

  • The absorption score ranks forms of the same compound against each other. It is not a measured share of the dose — see how we derive it.
  • Safety rating reflects tolerance at normal doses, not toxicity risk.
  • Cost is per month at the typical daily dose, so a cheaper form taken at double the dose is not cheaper.
  • Evidence level A means the form itself was studied, not just the parent compound.

Common questions

Which is better, Bovine Collagen or Marine Collagen?

Marine Collagen absorbs better — 95% against 90%. Absorption decides how much of the dose actually reaches you, so it usually matters more than the milligrams printed on the label.

What is the difference between Bovine Collagen and Marine Collagen?

They are different substances from the same group, so they do not do the same job. They also differ in how well the body takes them up, how they are tolerated and what a month costs: $45 against $60.

Can you take Bovine Collagen and Marine Collagen together?

Yes — they are different substances, so taking both is normal and often the point. Check each one against your other supplements rather than against each other.
