Yu Sleep Ingredients: What Is in Each 2 mL Serving

Ten ingredients inside one amber dropper bottle is how the seller puts it, and the panel on the bottle bears out the count. Our ingredients article adds more background.

With any new supplement, speak to your doctor first and leave your prescriptions alone.

The panel at a glance

Each serving is 2 mL (two full droppers); roughly 30 fit in a bottle.

No Daily Value figures are given for the blend or melatonin, so none are quoted here.

The ten, one at a time

Melatonin and the two B vitamins are listed on their own lines. The other seven sit together in the blend.

Melatonin

A hormone your body produces after dark, and a name most shoppers know from the sleep aisle. A serving of Yu Sleep carries 0.9 mg.

Vitamins B2 and B6

Two B vitamins at 0.5 mg apiece. The label names their forms as riboflavin 5-phosphate (B2) and pyridoxal 5-phosphate (B6).

Red tart cherry juice concentrate

Tart cherries pressed and concentrated; it is named first among the seven.

Magnesium glycinate

The mineral magnesium joined to glycine, an amino acid.

Apigenin

A plant compound, best known as a component of chamomile.

Lemon balm extract

Taken from a mint-family herb with leafy stems, often brewed as an evening tea.

5-HTP

Short for 5-hydroxytryptophan, here sourced from Griffonia seed. It is the reason the safety guidance tells antidepressant users to see a doctor before starting.

L-theanine and GABA

Both are amino acids. L-theanine is the one that occurs in tea leaves.

What carries the liquid

Distilled water and glycerin make up the liquid, sweetened with medium invert syrup and erythritol. Citric acid, sodium citrate and potassium sorbate are in there too, plus natural flavors, gum arabic and xanthan gum. Anyone on a restricted diet should read the entire list on the bottle.

A note on the blend

The label gives one 637 mg figure for the whole seven-part blend, with no separate amount for each. You see the full cast and the combined weight.

Who will like this label

• Shoppers who want every ingredient named before they pay
• People who prefer one formula to several separate bottles
• Adults after an evening step they can finish in seconds

Melatonin and 5-HTP are in the formula. Anyone taking an antidepressant, an anxiety drug, a sleep aid or blood-pressure pills, and anyone pregnant or feeding a baby, should consult a doctor beforehand. Adults only.
