Nature Made Men's Pack Review

Iodine at this full dose matters mainly for people who lack it. In iodine-poor areas it cut cretinism in children of supplemented mothers ^[1] and shrank goitre ^[2], but too much can harm the thyroid ^[3]. Selenium at this full dose lowered thyroid antibodies and thyroid-stimulating hormone in people with Hashimoto thyroiditis ^[4], and in people with a mildly underactive thyroid it restored normal function in 31% versus 3% ^[5]. One review still judged the evidence too weak for routine use ^[6]. Zinc and magnesium, at full dose with two servings a day, raised free thyroxine in underactive thyroid when given together with vitamin A ^[7][8], but zinc results overall are inconsistent ^[9]. Vitamin C at full dose gave mixed results, with no effect on antibodies in a placebo trial ^[10]. Vitamin D, at full dose with two servings, lowered antibodies in pooled trials ^[11], though another review found no effect ^[12]. Vitamin A here is well below the studied dose ^[13]. The potassium benefits came from iodine or bromide, not potassium itself. Most other vitamins and minerals showed no thyroid benefit ^[14]. Animal and cell studies are never counted.

Nine of the ten panelists spoke about zinc, the main ingredient, and the group leans toward recommending or using it, while one panelist spoke about selenium instead and recommended it for healthy immune regulation. Four of them recommend zinc for body functions, mainly testosterone and prostate health, and one also suggests it with magnesium for sleep. Others use it for gut lining support (as zinc carnosine), for immunity alongside vitamin C, in a skin sunscreen, or for a patient's arthritis, and one takes 15 mg in the morning for longevity. One panelist's surgery plan includes zinc for wound healing, and the same panelist cautions that going over the right amount of zinc can lead to a copper deficiency. Vitamin D, magnesium and vitamin C are smaller ingredients in this product, and most of the panel also speaks well of them.
