Amino Acid testing

[Guest guest]

My son Philip (age 13) recently had urine amino acid testing done

through IWDL. Even though he eats a varied high-protein diet, the

testing showed that he was low in a number of essential amino acids.

This suggests he has a problem with digestion and absorbtion. The

recommendation is to give him customised amino acid supplementation.

The dosage levels are very high.

We were wondering whether to get blood amino acid testing done as well,

to see if the results are confirmed. Has anybody done either urinary

or blood amino acid testing and used supplmentation, with positive (or

otherwise!) results?

We'd be grateful for any advice.

Thanks
