Brand: Sundown Naturals · Form: GUMMY [E0176]
Our assessment
The evidence shows that the primary active ingredient in Sundown Naturals Fiber Gummies with Vitamin D3 is calcium, based on the data provided. For a general audience, we can say that calcium is essential for bone health, but you need to be careful about dosing. The data does not specify the exact amount of calcium or vitamin D3 in this product, so we must state: Data not available for the specific formulation.
How it works
Think of calcium as a building block for your skeleton. It supports bone density and mineral deposition, which is crucial for keeping your bones strong as you age. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Side effects from too much calcium include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Our assessment: Do not exceed the RDA for calcium without consulting your doctor. Be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Since the exact vitamin D3 content is not provided in the data, you should check the label carefully. If you have a history of kidney stones or heart disease, speak with your pharmacist before starting this product.
