“Love it. 44 F. Totally helped even out my skin tone (Irish red cheeks), reduced wrinkles on my forehead and neck, thickened my hair which had been thinning, and grew my eye lashes.”
This review confirms that the quality of literature is substandard for physicians to make well-informed recommendations on usage of oral magnesium for older adults with insomnia. However, given that oral magnesium is very cheap and widely available, RCT evidence may support oral magnesium supplements (less than 1 g quantities given up to three times a day) for insomnia symptoms.
