What is Night Blend (Astera Labs)?

Melatonin with amino acid support, for sleep and overnight recovery. The melatonin is the part doing the work.

Melatonin is the hormone that signals night to your body, and at 2mg it is at a dose that shifts sleep timing and shortens how long it takes to fall asleep. GABA and glutamine work on the calming and recovery side, and arginine is included because growth hormone release peaks during deep sleep, which is where a lot of overnight recovery actually happens.

Night Blend benefits

Melatonin at 2mg, which is a working dose rather than a token one
Aimed at both falling asleep and the recovery that happens once you are asleep
Glutamine and arginine on the recovery side
No sedative, so no grogginess the following morning
Not hormonal in the androgen sense, so nothing is suppressed

Night Blend dosage

Standard: 1ml, 30 to 60 minutes before bed
Melatonin: 2mg per ml
GABA: 50mg per ml
L-arginine: 50mg per ml
L-glutamine: 30mg per ml
Timing: Evening only

1ml half an hour to an hour before bed. Evening only, since melatonin shifts your body clock and a daytime dose works against you.

Melatonin works better at lower doses than people assume. If 1ml leaves you groggy, less rather than more is the answer.

Who is Night Blend for?

People whose sleep is the weak link in their recovery, which for anyone training hard is more often the case than they think.

It is the evening half of a pair with Day Blend. If you want sleep support without melatonin, DSIP is the alternative, though the evidence for it is weaker.

Before you use it. Melatonin is a hormone, though not an androgen, and it shifts your body clock rather than sedating you. Use it in the evening only; a daytime dose pushes your clock the wrong way. Vivid dreams are common and harmless. Lower doses generally work better than higher ones for sleep, which is unusual and worth knowing. Do not drive after taking it. Nothing in it is hormonal, so nothing is suppressed and no post-cycle therapy applies. Store cool, dry and out of direct sunlight. Not for anyone under 18, and not for women who are pregnant or breastfeeding.
