Carnitine results-can someone explain?

[Guest guest]

Below are my son's carnitine results. Can anyone eplain to me what the

difference is between total, free etc? Right now he is on 500 mg 2x/day of

L-Acetyl Carnitine. A few months ago he was on 500 mg 1x/day and I took him off

for 2 weeks and tested him and his free number was 3 pts higher and his total

number was 2 points lower. It seems like his numbers should be higher than this

on 1000 mg/day??

So my questions....1. what do the different categories mean? 2. Optimal results

should be higher right?

total 35 range 32-62

free 25 range 25-54

esters 11 range 4-12

esterified/free ratio .43 range .09-.35

Thanks!
