Synopsis

Rating (out of 5): 5
Vitamin D2 (ergocalciferol) is scientifically validated for its use in supporting the parathyroid glands and overall calcium homeostasis. The parathyroid glands regulate calcium and phosphate metabolism in the body through the secretion of parathyroid hormone (PTH). Vitamin D2, when ingested, is converted in the liver to 25-hydroxyvitamin D and then further hydroxylated in the kidneys to the active form, 1,25-dihydroxyvitamin D. This active form enhances intestinal absorption of calcium and phosphate, which is crucial for maintaining appropriate blood calcium levels. When calcium levels are low, PTH is secreted to increase calcium, partly by stimulating the activation of vitamin D in the kidneys. Thus, adequate vitamin D (including D2) is essential for the parathyroid glands to carry out their regulatory functions. Clinical guidelines, such as those from the Endocrine Society and the National Institutes of Health, recognize vitamin D2 as an effective treatment for vitamin D deficiency, which can lead to secondary hyperparathyroidism—a compensatory overactivity of the parathyroid glands in response to low calcium. Supplementation with vitamin D2 has been shown to normalize PTH levels and restore calcium balance. While vitamin D3 (cholecalciferol) is more commonly used due to its slightly higher potency, D2 is FDA-approved and widely used in medical practice for the same indications. Therefore, the use of vitamin D2 to support the parathyroid glands is well-established and strongly supported by scientific evidence.
