Hair 15N levels provide an accurate medium-to-long term biomarker for dietary EPA and DHA intake, reflecting the previous two months of consumption, whereas blood 15N reflects a shorter period.
Hair 15N levels can accurately reflect your EPA and DHA intake over the previous two months, offering a more long-term view than blood tests.
GoodSupportsHIGH confidence
Hair 15N was correlated with dietary EPA and DHA (r=0.83, 0.84, respectively)... Hair 15N is able to reflect the previous two months of intake
Why this rating
