Carlson Labs Melatonin delivers a conservative 300 mcg (0.3 mg) dose of melatonin, a naturally occurring hormone that supports healthy sleep onset and circadian rhythm regulation. This low-dose format is designed for adults seeking gentle sleep support without the higher doses found in most commercial melatonin products.
Why It's Worth Considering: At 300 mcg, this formulation aligns closely with doses studied in sleep research, making it a practical option for those who find standard 3–10 mg doses excessive or who prefer starting with a physiologically modest amount.

More category questions
How much melatonin should I take?
Start with 0.3-0.5mg — this is the physiological dose that mimics natural production. Most supplements are dosed at 3-10mg which is 10-30x the physiological amount. Higher is NOT better — studies show 0.3mg is often more effective than 3mg because excess melatonin can cause morning grogginess and disrupt the receptor sensitivity.
Is melatonin safe to take every night?
Short-term use (up to 3 months) is well-established as safe. Long-term nightly use is common but some practitioners recommend periodic breaks (5 nights on, 2 off) to maintain receptor sensitivity. Melatonin does not cause dependence — your body still produces its own. However, addressing the root cause of insomnia (light exposure, stress, caffeine timing) is always preferred.
Why do I feel groggy after taking melatonin?
You're likely taking too much. The most common mistake is using 3-10mg when 0.3-1mg is sufficient. Melatonin is a circadian signal, not a sedative — excess stays in your system and causes morning drowsiness. Try cutting your dose in half. Also, take it 30-60 minutes before bed, not right at bedtime.
Does melatonin work for jet lag?
Yes — this is one of melatonin's best-studied uses. Take 0.5-3mg at the destination's bedtime for 3-5 days after arrival. For eastward travel (harder adjustment): start taking melatonin at destination bedtime 1-2 days before departure. For westward: take melatonin only upon arrival.
