Sensoril® Ashwagandha

125 mg per stick

Supports the body’s response to everyday stress.*

What it isSensoril® is a branded extract made from ashwagandha root and leaf.

Why it’s in WinksChosen for the everyday-stress layer. Sensoril® is a standardized root-and-leaf extract, used at 125 mg, the daily amount in its 8-week study.

Rounded percentages calculated from published group averages. Week-eight scores did not differ significantly between these two groups. Ingredient research—not a Winks trial.

Affron® Saffron

28 mg per stick

Supports better sleep quality.*

What it isAffron® is a branded saffron stigma extract, standardized for its key compounds.

Why it’s in WinksChosen for sleep quality. Affron® is the standardized saffron extract used in both placebo-controlled trials below, at the 28 mg daily amount.

Organic Tart Cherry

480 mg per stick

Provides polyphenols—naturally occurring plant compounds. Its effects on sleep depend on the preparation studied.

What it isTart cherry is a fruit. Winks uses it in a measured powder form.

Why it’s in WinksIncluded for its naturally occurring polyphenols. We use a measured organic powder so every stick carries the same 480 mg.

Different preparations; neither establishes a sleep benefit from the powder amount in Winks.

Magnesium Bisglycinate

100 mg per stick

Helps nerves send signals and muscles function normally.*

What it isBisglycinate is magnesium bound to the amino acid glycine.

Why it’s in WinksChosen as the mineral layer. We use the bisglycinate form, magnesium bound to glycine, at 100 mg so it fits in one stick alongside calcium.

The study used a higher dose and different form—not the magnesium amount in Winks.

Organic Lemon Balm

300 mg per stick

Studied for calming effects during stress; results vary by extract and preparation.

What it isLemon balm is a leafy botanical in the mint family.

Why it’s in WinksOne half of the calming botanical pair, with passion flower. Organic lemon balm at 300 mg makes up most of the 450 mg of evening botanicals in each stick.

Standardized extract in drinks or yoghurt—not a trial of the Winks ingredient or finished drink.

Organic Passion Flower

150 mg per stick

Studied for sleep quality and duration, with early findings from tea and extract trials.

What it isPassionflower is a flowering botanical, also called Passiflora incarnata.

Why it’s in WinksThe other half of the calming botanical pair. Organic passion flower at 150 mg rounds out the 450 mg of evening botanicals in each stick.

Tea is not equivalent to the passionflower material or amount in Winks; this was not a Winks trial.

Phosphatidylserine

100 mg per stick

Forms part of cell membranes, including those of nerve cells, and helps support cell signaling.

What it isPhosphatidylserine is a phospholipid, a type of fat found in cell membranes. Ours is sourced from sunflower seeds.

Why it’s in WinksIncluded in the stress layer alongside ashwagandha. We chose a sunflower-derived, soy-free source at 100 mg, the lower amount used in the study below.

The study used soy-derived phosphatidylserine, not the sunflower-derived ingredient in Winks, and did not test sleep.

Calcium

200 mg per stick

Helps muscles contract and nerves carry messages. It also supports bones and teeth.*

What it isCalcium is a mineral. Winks supplies it in calcium citrate form.

Why it’s in WinksIncluded as the second mineral in the formula, in citrate form at 200 mg. Calcium is paired with magnesium rather than used alone.

Association is not cause and effect. This was not a trial of calcium supplements or the amount in Winks.

Lithium Orotate

0.5 mg per stick

Lithium can affect cellular signaling. A sleep benefit from this trace amount has not been established.

What it isLithium orotate is the form used for the trace lithium amount in Winks.

Why it’s in WinksIncluded as a trace mineral at 0.5 mg, far below prescription amounts. We use the orotate form and keep the amount fixed in every stick.

A review—not a sleep trial. Findings from prescription lithium cannot be applied to this trace amount.
