The formula is designed for the use of adults.


1) Sleep Nice Quick Facts

Sleep Nice is an herbal-based dietary supplement.

The valerian is a medicinal plant commonly used to treat sleep disorders due to its capability to increase GABA levels. The root is believed to be most effective, but it is not known which of its constituents are responsible for the plant’s benefits. Valerian is also used to reduce ADHD, anxiety, psychological stress, depression, migraines, and stomach upset. However, most of its benefits are sometimes exaggerated and it is very important to remember that plant extracts may sometimes be toxic. Valerian was shown effective in treating insomnia with noticeable benefits after approximately a month of use. Safety on long term and in children is unknown. The plant is not recommended for people who are operating heavy machinery or while driving.

Chamomile is an herb used for centuries to treat insomnia, anxiety, slow-healing wounds, eczema, gum inflammation, and upset stomach. The plant owes its benefits to bisabolol and couramin, the active compounds that give chamomile the anti-inflammatory, anti-microbial, and anti-anxiety effects. While bisabolol seems to lack side effects, couramin may interact with anticoagulants increasing the risk of hemorrhage. However, adverse reactions occur when higher amounts of the constituent are consumed. The most potent part of chamomile is the flower which is most commonly dried and used to make tea. Other forms of chamomile remedies are tinctures, liquid extracts, creams, and ointments.

The recommended dose of Sleep Nice is 1-2 capsules daily at bedtime.

3) What Does Sleep Nice Do?

Sleep Nice formula is an herbal based dietary supplement.

St. John’s Wort (Hypericum perforatum) has been used in traditional medicine to treat mental health conditions and heal wounds. It is believed to be very effective in alleviating depression and anxiety symptoms, as well as a variety of sleep disorders. It is not uncommon for the plant to be recommended to reduce fatigue and exhaustion, usually associated with the aforementioned conditions. The advantage of St. John’s Wort over prescription drugs (antidepressants) is that it promotes a quality sleep without the drowsiness caused by the latter. The way it does so is by allowing the patient to enter the REM sleeping phase, essential for mental health. Scientists have agreed also that a certain dose used regularly reduces the symptoms of mild depression. Some of the potential side effects are skin rash, nausea, fatigue, dizziness, anxiety, sexual dysfunction, and confusion. The plant may interact with other antidepressants, anticoagulants, and contraception pills.

Passion Flower is also used in the treatment of insomnia, spasms, hypertension, asthma, burns, high blood pressure, and seizures. Scientific evidence supports the use of passion flower in the treatment of anxiety and the symptoms of narcotic withdrawal, but evidence is controversial as regards to all the other uses. Side effects include dizziness, confusion, and poor coordination of muscles. It is not recommended when operating machinery or in the cases of pregnant or nursing women (it may cause contractions in the uterus). The extracts may also interact with anticoagulant medication other sedative drugs.

There are no testimonials to support the Effectiveness of the formula. This is not a well-researched dietary supplement.The recommended dose of this product is 1-2 capsules daily before bedtime.

How To Use

The effectiveness of this formula is measurable judging by the effectiveness of the active ingredients and the reputation of the manufacturer. There are no studies involving this specific formula or any other evidence (including testimonials) to prove the formula actually brings benefits to its users.


8) Our Final Take On Sleep Nice

This relaxation formula is based on a blend of 4 natural remedies commonly used to treat sleeping problems. The daily value for the active ingredients is not established in the USA and no evidence of a clinical trial involving the formula is available. Also, the manufacturer does not mention the concentrations from each ingredient used to create the formula.

It is impossible to evaluate the effectiveness of Sleep Nice given the fact that it is unknown if the beneficial compounds are used in potent amounts and there are no testimonials to support the health claims.

It is therefore best to consult a healthcare professional before deciding to use the formula, especially because it is known that the active substances may interact with certain drugs.
