Our assessment
The evidence shows that Doctor's Best Best Collagen Types 1 & 3 contains calcium as an ingredient. For calcium specifically, our assessment is that it plays a crucial role in bone health, but you need to be cautious about your total intake from all sources, including supplements and food [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition through a process called bone mineralization. It also helps your muscles relax and supports proper nerve signaling [NIH ODS].
Safety profile
Data not available for side effects specific to this product. However, for calcium, the safety profile includes important warnings. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the 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]. The FDA has received a total of 592059 adverse event reports across all supplements, but specific counts for this product are not available [FDA data].
Our recommendation
Start by evaluating your total daily calcium intake from food and other supplements. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these medications, you should separate your doses by at least two hours [NIH ODS]. We recommend you speak with your doctor before adding this supplement to your routine, especially if you have a history of kidney stones, heart disease, or take prescription medications.
