Reset/360 BY DR. SARA GOTTFRIED Daily Fiber

Our assessment

The evidence shows that Reset/360 Daily Fiber contains calcium as an active ingredient. For a general audience, calcium supports bone health and muscle function, but you need to be aware of specific risks and medication interactions before adding this supplement to your routine [NIH ODS].

How it works

Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].

Safety profile

Data not available for this specific product’s adverse events. The total number of adverse event reports for all supplements in the FDA database is 592,059 [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high levels in your blood and urine can cause 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].

Our recommendation

You should check your total daily calcium intake from food and other supplements to avoid exceeding safe levels. If you take any medications — especially bisphosphonates, tetracycline or fluoroquinolone antibiotics, levothyroxine, or phenytoin — take this fiber supplement at a different time of day, as calcium can reduce their absorption [NIH ODS].
