The Short Answer
Olly Sleep is a convenient gummy with melatonin and L-theanine. It works for people who need a simple sleep nudge. But it has only 4 active ingredients, uses a higher melatonin dose (3mg vs 0.9mg), and arrives in gummy form that slows absorption.
Yu Sleep is a 9-ingredient nano liquid designed for people who want more than a gummy can deliver - especially if 3 AM wake-ups and racing thoughts are the real problem.
What Is Olly Sleep?
The formula: 4 active ingredients
Olly Sleep contains four active ingredients: melatonin (3mg), L-theanine, chamomile extract, and passionflower extract. It comes as a gummy with added sugar, gelatin, and natural flavors.
The formula is simple and well-tolerated. Melatonin tells your body it is bedtime. L-theanine calms racing thoughts. Chamomile and passionflower provide mild herbal calming. It is a reasonable entry-level sleep supplement.
The limitation is breadth. Olly targets two sleep mechanisms (melatonin signal and mild calming). Yu Sleep targets five.

The Absorption Problem
How fast a supplement absorbs matters more than most people think.
Olly Gummy (Digestive)
- ✗Must dissolve in stomach acid first
- ✗Passes through liver first-pass metabolism
- ✗Active ingredients reduced by 30-60% before reaching bloodstream
- ✗Takes 20 to 45 minutes to feel effects
- ✗Sugar and gelatin slow digestion further
- ✗Bioavailability varies based on what you ate that day
- ✗Some ingredients destroyed by stomach acid
Yu Sleep (Sublingual Nano)
- ✓Absorbs through sublingual tissue in 30 seconds
- ✓Bypasses liver first-pass metabolism entirely
- ✓Nano-sized molecules enter bloodstream directly
- ✓Effects felt within minutes, not 30+ minutes
- ✓No sugar, gelatin, or fillers to slow absorption
- ✓Consistent bioavailability regardless of meals
- ✓All 9 ingredients reach full concentration in blood
Sublingual delivery means the active ingredients go directly into your bloodstream through the tissue under your tongue. No stomach acid, no liver processing, no loss.
Ingredient-by-Ingredient Breakdown
What each formula contains and what it means for your sleep.
Melatonin (0.9mg)
Olly: 3mg
Yu Sleep uses a lower, more precise dose supported by other ingredients. Olly relies on a higher melatonin dose as the primary sleep signal.
L-Theanine
Both contain it
Both formulas include L-theanine for calming alpha brain waves. Yu Sleep pairs it with GABA for stronger nervous system calming.
GABA
Olly does not contain
Quiets overactive brain activity. Olly has no equivalent - it relies on L-theanine and passionflower for calming.
Lemon Balm Extract
Olly does not contain
Specifically targets the cortisol spike that wakes you at 3 AM. Olly cannot address this mechanism.
Magnesium Glycinate
Olly does not contain
Promotes deep sleep stages. Over 50% of adults are deficient in magnesium. Olly does not address this gap.
5-HTP
Olly does not contain
Supports serotonin production, which converts to melatonin naturally over time. Olly has no equivalent.
Vitamin B6 & B2
Olly does not contain
Help your body produce its own melatonin. Olly provides synthetic melatonin instead of supporting natural production.
Apigenin
Olly does not contain
A plant flavonoid that shortens time to fall asleep. Olly has chamomile (which contains apigenin) but in lower concentration.
Red Tart Cherry Extract
Olly does not contain
One of the richest food sources of natural melatonin. Supports your body's own production.
