Best Melatonin with L-Theanine (2026): Which Blend Should You Buy?

Every other blend on this page is measured against this one. OLLY Sleep states 3 mg melatonin and names L-theanine in its title, 70 count. The L-theanine amount is not published, so we do not state one and credit it with nothing the label does not claim; the Supplement Facts panel has it. $16.35 divided by 70 is about 23 cents a gummy.

The line around it is the other reason to buy in: a 50 count at $11.90 to try it, a 120-count pouch at $29.99, and Extra Strength 5 mg for people who have used more. OLLY also carries the pairing into its kids line, OLLY Kids Sleep 0.5 mg with L-theanine, which is a pediatrician's decision and the Family Desk's territory. The full line is in the OLLY Sleep review.

Six cents a gummy less than OLLY, with one number missing. Natrol Sleep+ Calm names melatonin and L-theanine, states strawberry and 60 count. $9.98 divided by 60 is about 17 cents a gummy. The melatonin amount is not in the title, so we do not state it; the panel does.

Natrol's line is the deepest in the category, and the same brand's 3 mg Fast Dissolve (90 for $7.32, about 8 cents) is the single-ingredient value if you decide the L-theanine is not worth paying for. The whole line is in the Natrol melatonin review.

A capsule carries no sugar and no two-gummy ambiguity, and NOW's is the one to buy. NOW Sleep Regimen 3-in-1 names melatonin, 5-HTP and L-theanine, and states 90 veg capsules. $16.89 divided by 90 is about 19 cents a capsule. None of the three amounts is published in the title; we credit the 5-HTP and L-theanine with nothing the label does not claim.

NOW's single-ingredient melatonin runs from a 1 mg tablet to a 20 mg capsule and is sorted in the NOW melatonin review; the capsule field is in best melatonin capsules and softgels.

The most complete premium title on this page. The MaryRuth's Melatonin 5 mg Sleep Gummy states 5 mg, names L-theanine and lemon balm, and states 60 count. $19.95 divided by 60 is about 33 cents a gummy. The amounts of the two additions are not published; we name them because the title does and credit neither with an effect the label does not claim.

MaryRuth's wider sleep line, including a melatonin-free L-theanine gummy and two liquids, is in the MaryRuth's sleep review.

More named actives than any other title on this page, at the highest amount. ZzzQuil Pure Zzzs Complete Sleep states 10 mg melatonin and names L-theanine, GABA, ashwagandha and magnesium. None of the four amounts is stated, and neither is the count. We name all four because the title does and credit them with nothing the label does not claim.

Pure Zzzs is the supplement line; the original ZzzQuil liquid is diphenhydramine, an over-the-counter drug with a Drug Facts label, and the two are not interchangeable. The whole family is in the ZzzQuil Pure Zzzs review, and the ashwagandha blends are ranked in best melatonin with ashwagandha.

Three named actives, clean-label claims, and no numbers. The SmartyPants Adult Fast-Acting Sleep Gummies name melatonin, magnesium and L-theanine, and state drug-free, gluten-free and clean label. The melatonin amount, the count, and the amounts of the two additions are all absent from the title. "Fast-acting" is the maker's positioning; we report it and do not vouch for it.

SmartyPants also sells the L-theanine pairing in its melatonin-free kids gummy, a pediatrician's decision covered by the Family Desk. The full line is in the SmartyPants sleep review, and the magnesium half of this formula is ranked in best melatonin with magnesium.

Under 4 cents a night, at an amount we would not start anyone on. Carlyle Melatonin 10 mg with L-Theanine states 10 mg, names L-theanine, and states 270 tablets. $9.99 divided by 270 is about 3.7 cents a night. The L-theanine amount is not stated. A swallowed tablet, no sugar question, nine months per bottle.

Carlyle's whole line, including its strong low-dose tablets, is in the Carlyle melatonin review, and every 10 mg format is in best melatonin 10 mg.
