Description
Melatonin alone doesn't fix a racing mind. NuBest Sleep Xtra pairs 4mg of melatonin with calming botanicals like ashwagandha, L-Theanine, and valerian — built as a non-habit-forming capsule for teens 10 and up and adults who need help winding down, not a knockout dose.
What's Actually in the Capsule
The formula groups 12 ingredients into three functional roles — calming the mind, easing sleep onset, and supporting the body's own melatonin production.
Ashwagandha, L-Theanine, Passionflower & Skullcap
Ashwagandha is an adaptogen used to ease stress and anxiety before it keeps you up. L-Theanine promotes relaxation by increasing alpha brain waves, while Passionflower and Skullcap work through GABA pathways to calm an overactive mind — the "racing thoughts" part of insomnia, not just the physical side.
Melatonin, Valerian, Chamomile & Hops
Melatonin signals the body that it's time to sleep. Valerian is well-studied for reducing the time it takes to fall asleep, Chamomile contains apigenin which binds to GABA receptors to induce sleepiness, and Hops adds a mild sedative effect traditionally paired with valerian.
Vitamin B6, Calcium & Magnesium
Vitamin B6 supports the body's own melatonin synthesis. Calcium helps metabolize tryptophan, the amino acid behind that sedative effect, and Magnesium is commonly paired with melatonin to support relaxation and longer sleep duration.
A sleep aid that only handles the physical side misses half the problem — a racing mind keeps you up just as much as low melatonin does.
How to Use It
Adults
Take 2 capsules 30 minutes before bedtime. If you have a more sensitive constitution, start with 1 capsule.
Teens and children ages 10+
Take 1 capsule daily, 30 minutes before bedtime, or as directed by a healthcare professional.
Can't swallow capsules?
Open the capsule and sprinkle the powder onto food or into a drink, then mix well before taking.
Daily or as-needed — either works
The brand notes some people use it nightly, others only when they need it. There's no single "right" way, since individual response varies.
This isn't meant for indefinite daily use without a break. The brand's own FAQ points to research suggesting short-term melatonin use (3 months or less, at up to 10mg daily) is fine for healthy adults, but long-term use at that level should be supervised by a healthcare professional.
Not intended for children under 10. The teen/adult dosing on this label starts at age 10 — younger children should not take this formula.
Where to Buy
Pricing may vary by retailer and change over time — always confirm current price before purchase.
Frequently Asked Questions
How much melatonin is actually in each serving?
4mg of melatonin per serving, alongside Vitamin B6 to support the body's own melatonin production.
Is this habit-forming?
No — it's formulated to be natural, vegan-friendly, non-habit-forming, and drug-free.
Do I need to take a break from using it?
Short-term use (3 months or less) is generally considered fine for healthy adults, but long-term daily use should be discussed with a healthcare professional, particularly given the melatonin content.
Why does it include Vitamin B6 and Calcium?
Vitamin B6 supports the body's natural melatonin production, which regulates the sleep-wake cycle. Calcium helps metabolize tryptophan, the amino acid behind its sedative effect.
Can it cause weight gain?
No — the formula isn't designed to affect body weight in either direction.
