Why It Works

Key Benefits

🧪
Three Products, Also Sold Separately
The bundle contains VitaNight Sleep Formula, Kasivit Magnesium Glycinate Capsules and Kasivit Ashwagandha Capsules with Black Pepper. The studies mentioned on this page tested single ingredients, mostly in specific groups of adults; none tested these products or this combination.
🌙
VitaNight: Contains Melatonin, Can Cause Drowsiness
A 2-capsule serving contains melatonin 2 mg with valerian, chamomile, GABA, L-tryptophan, lemon balm and passion flower extracts. In a meta-analysis of 19 trials, melatonin shortened the time to fall asleep by about 7 minutes compared with placebo (a modest effect); results for valerian were mostly no different from placebo, and evidence for oral GABA on sleep was very limited. A 2017 American Academy of Sleep Medicine guideline suggested that clinicians not use melatonin, tryptophan or valerian to treat chronic insomnia (weak recommendations). Do not drive or operate machinery after taking it.
🧘
Magnesium Glycinate: Small Effect in One Trial
A serving provides 275 mg of elemental magnesium from 2,500 mg of magnesium glycinate. In a 4-week trial of 155 adults reporting poor sleep, 250 mg of elemental magnesium a day as bisglycinate lowered insomnia scores slightly more than placebo; the authors called the effect size small. The US upper limit for magnesium from supplements is 350 mg a day for adults, and magnesium can cause loose stools.
🌿
Ashwagandha: Studied as Standardized Extracts
A meta-analysis of five trials (400 people) found a small improvement in sleep with ashwagandha extract, and another found lower cortisol but no significant effect on perceived stress. This product lists organic ashwagandha root with black pepper, not a standardized extract, so the results may not apply to it. Rare cases of liver injury have been reported with ashwagandha supplements.
⚠️
Check Medicines Before Combining
VitaNight contains melatonin, valerian and passion flower, and ashwagandha and magnesium are also taken in the evening, so ask your prescriber or pharmacist before combining these products with sedatives, sleep medicines, antihistamines, antidepressants or alcohol. Ask first if you take thyroid medicines, immunosuppressants, antibiotics or blood-pressure medicines. Do not stop or change a prescribed medicine because of a supplement.

Product notes
Editorial Team's Note
Editorial note: This bundle groups three separate Kasivit products. The studies mentioned on this page tested single ingredients, usually in specific groups of adults, and found small or mixed effects on sleep (for example melatonin shortened the time to fall asleep by about 7 minutes in a meta-analysis, and valerian trials mostly showed no difference from placebo); none tested these products or their combination. VitaNight contains melatonin and can cause drowsiness. Ask your prescriber or pharmacist before use if you take sedatives, sleep medicines, antidepressants, thyroid medicines or any other medicine, and speak with a doctor if sleep trouble is persistent.*

Three Kasivit products sold together: VitaNight, Magnesium Glycinate and Ashwagandha with Black Pepper.

These are three separate products that are also sold individually. The combination has not been studied. VitaNight contains melatonin and can cause drowsiness, so do not drive or operate machinery after taking it. None of these products is a treatment for insomnia, anxiety or any other condition. If sleep trouble is persistent, speak with a doctor, because it can have medical causes.

VitaNight Sleep Formula — per the confirmed label, a 2-capsule serving contains melatonin 2 mg (1 mg per capsule), valerian extract 150 mg, chamomile extract 100 mg, GABA 100 mg, L-tryptophan 100 mg, lemon balm extract 100 mg and passion flower extract 100 mg. The capsule is gelatin (not vegan). In a meta-analysis of 19 randomized trials in people with primary sleep disorders, melatonin shortened the time to fall asleep by about 7 minutes and increased total sleep time by about 8 minutes compared with placebo, effects the authors called modest (Ferracioli-Oda 2013). A review of 29 controlled trials of valerian found that most showed no significant difference from placebo (Taibi 2007), and a review of oral GABA found very limited evidence for sleep (Hepsomali 2020). These studies tested the ingredients on their own, and no study of VitaNight is cited.*

Kasivit Magnesium Glycinate Capsules — per the confirmed label, a 3-capsule serving provides 275 mg of elemental magnesium from 2,500 mg of magnesium glycinate. In a 4-week trial in 155 adults reporting poor sleep, 250 mg of elemental magnesium a day as bisglycinate lowered Insomnia Severity Index scores slightly more than placebo (-3.9 vs -2.3 points), and the authors called the effect size small (Schuster 2025). The US upper limit for magnesium from supplements is 350 mg a day for adults (it was set in 1997 with diarrhea as the limiting factor), so count magnesium from all supplements. No study of this product is cited.*

Kasivit Ashwagandha Capsules with Black Pepper — organic ashwagandha (Withania somnifera) root and organic black pepper fruit in pullulan capsules; the supplier's suggested use is 2 capsules once a day. A meta-analysis of five randomized trials (400 people) found a small but significant improvement in overall sleep with ashwagandha extract compared with placebo (Cheah 2021), and a meta-analysis of seven trials found lower cortisol but no significant effect on perceived stress scores (Albalawi 2025). These trials tested standardized extracts, not this product. Cases of liver injury have been reported with ashwagandha supplements, usually starting 2 to 12 weeks after beginning (Bjornsson 2020).*

Bundle price of $84.99 vs. $94.97 when the three products are bought separately.
