The evidence shows that the calcium in New Chapter Probiotic GI Tract is essential for bone health, but you need to be aware of the risks associated with high intake. Data on the specific probiotic strains in this product is limited to what is provided here [NIH ODS].

How it works

Calcium acts as a master regulator for your bones and nerves. It supports bone density and mineralization, and also helps 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 high levels include constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS].

Our recommendation

Start by checking your total daily calcium intake from food and other supplements. Calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine. Take this product at least two hours apart from those medications [NIH ODS].
