III Do an Amino Safety Check 

General Precautions:

□ If you take medications or herbs regularly, ask your pharmacist to research any

interactions between them and the amino acids you plan to try.

□ If you don’t generally tolerate supplements well, you may be intolerant to some or all

aminos. Trial at ¼ doses from opened capsules to find out. Or order a Trialing Kit.


If you check off any of the boxes below, please avoid all amino acids unless you have medical


□ If you have serious physical illness

□ If you have severe liver or kidney problems (e.g., hepatitis or lupus)

□ If you have an ulcer (amino acids are slightly acidic)

□ If you are pregnant or nursing (no individual amino acids are recommended, but a

total amino blend maybe be used with your OB’s OK e.g. Total Amino Solution by


□ If you have schizophrenia, bipolar spectrum disorder, or other mental illness

(and are not stabilized on medication)



Specific Amino Precautions for Each Craving Type

I have marked with Xs the amino supplements that are known to sometimes have certain adverse effects on some people.

Type 1 Precautions

Possible Contraindications 5-HTP Tryptophan Melatonin Adverse Reaction Levels

You take a serotonin-targeted SSRI (including Zoloft, Lexapro, Prozac, Paxil), a tricyclic (including Pamelor, Norpramin), or MAOI antidepressants. Check with your pharmacist or prescriber to be sure, and to get information on possible interactions









Moderate to severe



·         If you’re on only one SSRI, check with your prescriber about taking a Type 1 amino 4-6 hours away from the drug.


You regularly take anti-migraine, anti-microbial, or other serotonin-targeted drugs (e.g., Imitrex,  linezolid, ecstasy)  





Moderate to severe

Check with your pharmacist


Asthma       X           X        X Mild to Moderate, but very rare*
A carcinoid tumor (that produces serotonin)       X         X DO NOT USE without medical approval**

Type 2 Precautions

We have seen or heard of very few adverse reactions to this much researched and lauded amino supplement, but here are two that we have seen a few of times.


Possible Contraindications Glutamine Risk Level
Rise in a diabetic’s blood sugar: Typically diabetics get improved blood sugar stabilization from glutamine, but on rare occasions they find that it raises blood sugar slightly. Monitor your blood glucose levels while you take this supplement, if you are diabetic. We have seen this ourselves only once.          X Mild
In the brain, glutamine regularly converts into the excitatory neurotransmitter glutamate, and vice versa. The two keep in proper balance that way, but if too much glutamate is made, an agitated reaction can take place in those who are on the bipolar spectrum (whether they’ve been diagnosed or not). We’ve seen depression relief, or an energy surge five times. We have seen manic reactions twice.          X Mild to Severe


Type 3 Precautions

As you can see in the box below, there are several conditions that might warrant caution or preclude the use of DLPA. One of the two aminos in DLPA, L-phenylalanine, has mildly stimulating properties so we occasionally see some jitteriness in reaction to a trial of DLPA. Any such reaction during your trial would let you know to take DPA instead. Ditto if you have elevated blood pressure. Keep track of your blood pressure if you decide to trial DLPA in that case.


Possible Contraindications DLPA DPA* Risk Level
Hyperthyroidism (Grave’s Disease)         X DO NOT USE
Melanoma         X DO NOT USE
Manic Tendencies         X DO NOT USE
High Blood Pressure         X DO NOT USE without a blood pressure cuff


Headaches, including Migraines         X Mild – Moderate
Hashimoto’s Autoimmune Thyroiditis         X Mild – Moderate

*DPA has not caused any of the above problems, though it can, in rare instances, convert to some LPA and increase energy slightly.



Type 4 Precautions

Note: Infants should not use GABA.

Possible Contraindications GABA Theanine Risk Level
It could cause too much sedation if taken at the same time that you take a GABA-targeted medication, e.g., alcohol, Neurontin (Gabapentin), or benzodiazepines like Klonapin, Ativan, Xanax, or Valium.  









Check with your pharmacist. With your prescriber’s okay, trial 4-6 hrs. away from the medication.

If your natural blood pressure is really low (under 105/65) or if you are on blood pressure–lowering medication**  





(Type 4 aminos can lower blood pressure further and make you lightheaded.) Start at half dose.

**GABA lowers blood pressure a little.


Type 5 Precautions

Possible Contraindications Tyrosine LPA Risk Level
Grave’s Disease Hyper (overactive) thyroid (Tyrosine is the central component of all thyroid hormones.)       X       X DO NOT USE

(Never use Type 5 aminos if your illness is active. If your thyroid has been removed or reduced by surgery, ask your doctor’s advice.)

Melanoma      X        X DO NOT USE even in remission

without MD advice

Bipolar spectrum tendencies: if mania or hypomania is a problem, these aminos can be too stimulating. (And we have not seen them lift bipolar or unipolar depressions.) *      X         X DO NOT USE
High blood pressure (on or off  medication)** Moderate to severe


Mild to moderate


Monitor your blood pressure, trial them at low doses. (Low doses of LPA are rarely a problem.) DO NOT USE if even low doses cause elevation.
Headaches,*** especially migraines: If you get relief from Imitrex (or any other serotonin-targeted migraine medication) you are more likely to be adversely affected by Type 5 aminos. Moderate to severe


Mild to moderate


Mild to severe

Tyrosine is more likely to trigger.

Hashimoto’s Autoimmune Thyroiditis ****         X        X Moderate to severe

These aminos cause jitteriness in 15% of our clients with this condition. *** (Trial at ½ dose.)

Use of stimulating drugs such as caffeine, Adderall, Dexadrine, meth, diet pills, energy drinks, cocaine        X Overstimulating if Type 5 aminos are used at the same time as these meds. (Good for withdrawing from such meds.)
