Declaration note

The public international Nutriversum table contains several internally inconsistent values for choline bitartrate, L-lysine and L-ornithine. The current Serbian Lama declaration lists 1,240mg choline bitartrate and 300mg each of L-lysine and L-ornithine per serving, consistent with the declared amounts per 100g.

For a specific production batch, the physical pack declaration should always take priority.

GABA and L-tryptophan in an evening formula

GABA is gamma-aminobutyric acid, naturally present in the body and an important inhibitory neurotransmitter. L-tryptophan is an essential amino acid involved in metabolic pathways associated with serotonin and melatonin synthesis.

This does not mean that a supplement containing GABA and L-tryptophan should be presented as a medicine for insomnia, anxiety or mood disorders. GH Powder Dark is a food supplement, not a treatment for these conditions.

High magnesium content

One serving provides 508mg magnesium, equivalent to 135% of the nutrient reference value. It is therefore not advisable to automatically combine GH Powder Dark with another high-dose magnesium supplement without checking total daily intake.

Larger amounts of supplemental magnesium may cause gastrointestinal discomfort or looser stools in sensitive individuals.

What does “GH” in the product name mean?

The name GH Powder should not be interpreted as proof that the product increases growth hormone secretion. The formula contains amino acids, GABA, minerals, choline and vitamin B6, but it should not be advertised as hormonal treatment or with a claim that it has been proven to raise growth hormone.

Directions

• mix 10.5g powder with 250ml water;
• take with the last meal of the day or immediately before bedtime;
• one serving corresponds to approximately 2 included scoops;
• the scoop is intended only as a measuring aid;
• the manufacturer recommends a digital scale for accurate measurement;
• take one serving daily;
• do not exceed the recommended daily intake.

Who may find it suitable?

• adult athletes and physically active people;
• users looking for a multi-ingredient evening formula;
• people who prefer GABA and L-tryptophan as a drink;
• users looking for amino acids combined with magnesium, zinc and vitamin B6;
• people who prefer a combined evening supplement rather than several separate products.

Important information

• one serving already provides 508mg magnesium, 10mg zinc and 5.15mg vitamin B6 – check total intake when using other vitamin and mineral supplements;
• the formula contains 800mg L-tryptophan; if you take antidepressants, sedatives, sleep medicines or other medicines acting on the nervous system, consult a doctor or pharmacist before use;
• if you already use separate GABA, tryptophan, 5-HTP, magnesium or another evening formula, do not automatically combine the products;
• the product is not a medicine for insomnia, anxiety, depression or other nervous-system disorders;
• the name GH Powder is not proof of increased growth hormone;
• if evening use causes drowsiness or reduced alertness, do not drive or operate machinery;
• contains Ponceau 4R, for which the declaration states that it may adversely affect activity and attention in children;
• not intended for young children;
• food supplements should not replace a varied and balanced diet and healthy lifestyle;
• keep out of reach of children.

Pharmacist's advice

GH Powder Dark is a concentrated multi-ingredient formula, so I would not view it as a simple evening magnesium supplement. One serving already provides 508mg magnesium, 1,200mg GABA and 800mg L-tryptophan together with several other amino acids.

If you already use a separate magnesium, GABA, tryptophan or another night-time formula, compare the declarations first. Duplicating several ingredients does not necessarily mean a better effect.

For an athlete's overnight recovery, adequate energy and protein intake, sufficient recovery time between demanding sessions and enough quality sleep remain fundamental. A supplement may complement the routine but cannot compensate for chronic sleep deprivation.

If you use antidepressants, sedatives or other medicines affecting the nervous system, I recommend checking the combination beforehand because of the L-tryptophan, GABA and overall complexity of the formula.
