Formula

Yu Sleep ingredients & declared dosages

Ingredient	Declared amount	Manufacturer / label context	Evidence / potential role
Vitamin B2 (Riboflavin)	Label-disclosed	Per 2 mL serving	Supports normal energy metabolism and cellular function; it is not established as a standalone sleep treatment. [seller][ods-riboflavin]
Vitamin B6	Label-disclosed	Per 2 mL serving	Supports normal neurotransmitter and amino-acid metabolism; total intake matters because chronic high supplemental doses can cause neuropathy. [seller][ods-b6]
Melatonin	0.9 mg	Per 2 mL serving	Melatonin is a circadian timing signal with evidence for selected sleep and jet-lag uses; this does not prove the finished Yu Sleep formula. [seller][nccih-melatonin]
Red Tart Cherry Concentrate	Not verified	Part of 637 mg proprietary blend; individual amount undisclosed	Tart cherry has small human sleep studies, but the undisclosed dose prevents matching Yu Sleep to those trials. [seller][fda-supplements-context]
Magnesium Glycinate	Not verified	Part of 637 mg proprietary blend; individual amount undisclosed	Magnesium is essential for neuromuscular function; evidence for sleep benefit from supplementation is mixed and dose-dependent. [seller][ods-magnesium]
Apigenin	Not verified	Part of 637 mg proprietary blend; individual amount undisclosed	Apigenin is a flavonoid studied mostly in preclinical settings; robust clinical sleep evidence for this dose is not established. [seller][fda-supplements-context]
Lemon Balm Extract	Not verified	Part of 637 mg proprietary blend; individual amount undisclosed	Lemon balm has limited human research for stress or sleep-related outcomes, but the Yu Sleep amount is not disclosed. [seller][fda-supplements-context]
5-HTP	Not verified	Part of 637 mg proprietary blend; individual amount undisclosed	5-HTP is a serotonin precursor; medication interaction risk is important, especially with serotonergic drugs. [seller][fda-supplements-context]
L-Theanine	Not verified	Part of 637 mg proprietary blend; individual amount undisclosed	L-theanine has small human studies related to relaxation and sleep quality, but the product dose is unknown. [seller][fda-supplements-context]
GABA	Not verified	Part of 637 mg proprietary blend; individual amount undisclosed	Oral GABA has limited human sleep/stress research; the undisclosed dose prevents direct comparison with studies. [seller][fda-supplements-context]

Use carefully

Safety, interactions & who should be cautious

Melatonin and the broader formula may cause drowsiness, vivid dreams, headache, dizziness, digestive upset or next-day sleepiness in some users. [nccih-melatonin]
5-HTP creates extra caution with serotonergic medicines; sedatives, alcohol and other calming products may also change tolerability. [fda-supplements]
Persistent insomnia, repeated nighttime waking, suspected sleep apnea, pregnancy/breastfeeding or medication use warrants professional guidance rather than relying only on a supplement. [nccih-melatonin]

Editorial evidence check

What the evidence says

Claim / question	Evidence assessment	Strength
Is Yu Sleep clinically tested as a finished product?	No qualifying published human trial of the current finished Yu Sleep formula was identified in the sources reviewed. [seller][fda-supplements]	not established
Does the 0.9 mg melatonin dose have a plausible rationale?	Melatonin has evidence for selected circadian and sleep-timing uses, but individual response varies and the evidence does not validate Yu Sleep as a finished formula. [nccih-melatonin]	limited
Can the seven blend ingredients be compared with clinical study doses?	Not reliably. They share one 637 mg proprietary blend and individual amounts are not disclosed. [seller]	limited

Potential strengths

Liquid format
Low disclosed melatonin dose
Current label and package structure are available

Important limitations

Seven blend ingredients lack individual doses
No qualifying finished-product trial identified
Detailed return terms are more restrictive than the headline guarantee suggests

Our assessment

Oriqeva assessment of Yu Sleep

Yu Sleep is most defensible as a convenient liquid sleep-support option rather than a proven insomnia treatment. The transparent 0.9 mg melatonin dose is useful, but seven other ingredients share an undisclosed 637 mg blend and no qualifying finished-product trial was found.
