Our assessment
The evidence shows that Carlson Hi-Fiber is a dietary supplement containing calcium.

Data not available for the specific amount of calcium in this product, so you must check the label carefully.
How it works
Calcium is a master regulator for your body. It supports bone density through bone mineralization and helps your muscles relax and your nerves signal properly [NIH ODS]. Think of it as the structural foundation for your skeleton and a key player in neuromuscular function.
Safety profile
The FDA has received a total of 592,059 adverse event reports for all dietary supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking the label for the exact milligrams of calcium per serving. Do not exceed 2,500 mg of total calcium per day from food and supplements combined. Take this supplement at least two hours apart from any prescription medications listed above. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before use [NIH ODS].
