简要总结
This study is investigating whether a new type of fish oil supplement, in the form of soft chews, leads to better absorption of omega-3s in the body compared to traditional fish oil capsules. Omega-3s, found in fish oil, are known to support heart health and reduce inflammation, but they may absorb better in certain forms. In this study, participants will take both types of supplements (soft chews and capsules) at different times to compare how well the omega-3s are absorbed. Researchers will measure the levels of omega-3s in the blood over several hours to determine if the soft chews offer a better option for people seeking the health benefits of omega-3s.
