Seredyn is an herbal over-the-counter sleep aid- pill which includes the following active ingredients: L-Theanine, passion flower, valerian root extract, niacinamide, and magnesium taurinate.

L-theanine, is an amino acid found in green tea. It is purported to produce a sense of relaxation within minutes. L-theanine increases the activity of Gamma-aminobutyric acid (GABA), a neurotransmitter that promotes relaxation and reduces anxiety. L-theanine is also thought to stimulate the release of dopamine, a neurotransmitter thought to promote calmness.

Passion Flower has been used as a natural anxiety treatment for centuries. Passion Flower may also reduce sedative withdrawals.

Valerian (Valeriana officinalis) is a perennial flowering plant, with sweet scented pink and white flowers. The flowers bloom in the northern hemisphere of Europe and North America from June to September. Valerian has been used as a medicinal herb since at least the time of the ancient Greeks and Romans. It is native to both Europe and North America, and has been used in many cultures around the world as a sedative and sleep aid. During World War II, English citizens received prescriptions for valerian root to help them endure the air raids.

Valerian is used to combat sleep disorders, restlessness, anxiety, and as a muscle relaxant. It is thought to work best when taken over longer periods, though its short-term use is common as well. Valerian root is not as potent a sleep herb as others, including prescription medications, but it does have less side-effect.
