Cramp Relax™ from Vitanica is an update to their long-time beloved Cramp Bark Extra™, now featuring Black Haw bark, an herb relative to cramp bark herb and also traditionally used in support of relaxing occasional muscle cramps during menses. This is the same formula, now with Black Haw; still featuring the thoughtful combination of supportive herbs and nutrients thought to soothe common menstrual cramps during menses. This change is due to a shortage of cramp bark worldwide.
