A member asked:
Do you think hair strand testing is more accurate than blood testing for things like magnesium and potassium deficiency?
A doctor has provided 1 answer
Absolutely not!: Think about it: it takes weeks for your hair to grow. Analysis will tell you what your minerals were weeks ago. Potassium and magnesium levels, which are important for your heart's rhythm, can change day to day. A blood sample gives you immediate data which is what is necessary for decision making.
