Short Answer: Plasma zinc is the single most important marker of zinc status. Urine zinc may decline faster in deficiency. Hair zinc increases with supplementation but does not decrease in deficiency. Plasma zinc is decreased by inflammation, oxidative stress, the ovulatory and luteal phases of the menstrual cycle, probably pregnancy and oral contraceptive use, and any kind of stress that leads to an adrenal output. If plasma zinc declines despite supplementation, corroborate that this reflects zinc status by showing normal hair zinc and low urine zinc. Use symptoms as the ultimate arbiter of whether zinc supplementation is helping.
