No supplement is inert, and a page claiming zero possible side effects is not being careful with you. Here is what is plausible given the formula, what is serious, and who should not take it without medical advice.
Plausible mild effects
Digestive symptoms are the most likely - nausea, loose stools or mild cramping - particularly when taken on an empty stomach, which is the labelled instruction. Taking it with a small amount of food usually resolves this. The liquid has a mildly bitter herbal taste that some people find lingers. L-Tryptophan can cause drowsiness in some people, which matters if you take it in the morning before driving. Eleuthero has been associated in some reports with restlessness or sleep disturbance, though it is not a stimulant. Headache is reported across most supplement categories.
Interactions that matter
This is the more important section. L-Tryptophan affects serotonin pathways and should not be combined with SSRIs, SNRIs, MAOIs, triptans, tramadol or other serotonergic agents without medical advice, because of serotonin syndrome risk. GABA may add to the effect of sedatives, benzodiazepines, sleep medication and alcohol. Eleuthero has been reported to interact with several medication classes including anticoagulants, digoxin and diabetes medication, and may affect blood pressure. L-Carnitine may interact with thyroid medication and warfarin. Show the label to a pharmacist if you take anything prescribed.

See NeuronGold PricingWhen to stop
Stop immediately and seek urgent medical attention for any sign of allergic reaction - rash, hives, facial or throat swelling, difficulty breathing. Stop and seek advice for jaundice, dark urine, persistent right-sided abdominal pain or unusual fatigue, which can indicate liver involvement. Stop for palpitations, agitation, confusion, fever or muscle rigidity, which alongside serotonergic medication could indicate serotonin syndrome. Not for use in pregnancy, breastfeeding, or under 18. Keep the batch number and report adverse events to the FDA's MedWatch programme.

Verdict
The plausible side effects are mild and mostly digestive, but the interaction profile is not trivial - tryptophan with serotonergic medication is the one that matters most. Anyone on prescription medication should check with a pharmacist before starting.
