The claim

What Sports Research claims

“Supports bone health and immune system”The principal claim, quoted verbatim.
  • “Vitamin D3 contributes to a healthy immune system”
  • “supports bone health by helping you metabolize calcium”
  • “Vitamin K2 helps ensure that calcium gets deposited in your bones where it’s needed for bone and arterial health”
  • “Supports Bone Health*”
  • “Unlock your maximum potential”Broad marketing rather than a testable outcome, so the report says that plainly instead of grading it.

In total we found 7 printed sentences on the page and label, making 4 claims that can each be checked against human research, plus marketing too broad to test. Each claim gets its own answer in the report.
