The Vitamin Shoppe D3 125 mcg (5000 IU)
Brand: The Vitamin Shoppe · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Vitamin D is a critical nutrient, but the specific product you are asking about — The Vitamin Shoppe D3 125 mcg (5000 IU) — contains a dose that is well above the standard RDA for most adults. Data for the active ingredient, calcium, indicates it supports bone mineralization and neuromuscular function [NIH ODS]. However, for this specific Vitamin D product, detailed ingredient-specific clinical study data is not available in the provided information.
How it works
Think of vitamin D as a master regulator for calcium. It helps your body absorb calcium from food, which is essential for bone density and mineral deposition. The calcium in your diet also supports neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].
Safety profile
Data not available for this specific product's side effects. However, the FDA has received a total of 592,059 adverse event reports across all dietary supplements. For the related mineral calcium, high intakes can lead to constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS].
Our recommendation
Start with a lower dose, such as 600-800 IU daily, and get your blood levels checked before taking 5000 IU. Be aware that calcium supplements can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Consult your doctor before starting this high-dose product.
