Melatonin is a powerful antioxidant compound that has been shown to be helpful for improving egg quality, especially when given in combination with folic acid and myo-inositol. In addition, melatonin is a frequently recommended natural ingredient for helping to restore normal sleep cycles in people with insomnia. OvaBoost contains a small amount of melatonin, similar to the amount given to trying-to-conceive women in clinical trials looking at the benefits of this natural ingredient for supporting egg health. When taken in the recommended dosage, we do not expect OvaBoost to impact your sleep cycle, or your day time energy levels or alertness. We do recommend that you take all capsules just before bedtime.
