Invigorate NOW Probiotic Ultra Cleanse

Our assessment

The evidence shows that the primary active ingredient in Invigorate NOW Probiotic Ultra Cleanse is calcium, a mineral essential for bone health. Our assessment is that this product can support your bone density and nerve function, but you must be cautious about your total daily calcium intake from all sources, including food and other supplements [NIH ODS].

How it works

Think of calcium as a structural builder and a signal messenger. It supports bone mineralization, helping to maintain strong bones, and it also aids in neuromuscular relaxation, which is important for proper muscle function and nerve signaling throughout your body [NIH ODS].

Safety profile

FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Side effects from high blood calcium levels 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

We recommend you check your total calcium intake from food and other supplements before adding this product. Calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, so separate dosing by at least two hours is advised [NIH ODS].
