Ingredient Safety

Nutrigold Vitamin D3 Gold recorded 2200 IU vitamin D3/serving (Mean = 1674.5 IU). A single serving exceeds the 600 IU Recommended Dietary Allowance (RDA) by 266.7% while two servings of this product exceed the 4000 IU/daily vitamin D Upper Limit (UL) by 10%.

Although dosing is high, toxicity is unlikely to occur; according to the National Institutes of Health (NIH), most clinical reports set a toxicity threshold of 10,000 IU - 40,000 IU vitamin D daily. The Mayo Clinic notes toxic reactions after several months' consumption of 50,000 IU vitamin D daily. Excess vitamin D may cause calcium build-up in the blood, leading to fatigue, stomach issues and, over extended exposure, kidney damage.
