Side effects

Advanced Amino Formula side effects: is it safe?

Short answer

The maker lists no side effects but warns that people with phenylketonuria (PKU) should take amino acids only under a doctor's supervision. Amino acids from supplements are generally well tolerated at label amounts; the main points to discuss with a doctor are L-tryptophan with antidepressants, kidney or liver disease, pregnancy and nursing.

What the maker says

The sales page says the formula contains only amino acids and names one group that needs medical supervision: people with PKU, a rare inherited disorder in which the body cannot process phenylalanine. The blend contains L-phenylalanine.

What is generally known about the ingredients

Amino acids in general: usually well tolerated at supplement amounts; some people notice stomach upset, nausea or bloating, especially with several tablets at once
L-phenylalanine: must be avoided or medically controlled in PKU
L-tryptophan: the body uses it to make serotonin; combining it with antidepressants or other medicines that affect serotonin needs a doctor's approval
Leucine, valine, isoleucine: must be restricted in rare inherited disorders of amino acid metabolism, such as maple syrup urine disease
Other ingredients (vegetable stearic acid, silica, cellulose coating): common tablet ingredients

Who should talk to a doctor first

People with PKU or another inherited disorder of amino acid metabolism
Anyone taking antidepressants, migraine medicines or other drugs that affect serotonin
People with kidney or liver disease, or on a protein-restricted diet
Anyone taking prescription medication or with a chronic condition
Pregnant or nursing women
Children and teenagers – the product is made for adults
