ProCaps Laboratories PQQ 20 mg
Brand: ProCaps Laboratories · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that PQQ (Pyrroloquinoline Quinone) is a supplement with emerging research, but the specific product from ProCaps Laboratories at 20 mg has limited data. Data for the ingredient calcium is provided, not for PQQ itself. For calcium, our assessment is that it is essential for bone health, but you must be cautious with dosing and interactions, as high intakes may pose risks [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a signal messenger for your nerves and muscles. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high levels 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. Some research also suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
For calcium, data not available for a specific PQQ product recommendation. If you are considering calcium, do not exceed the RDA without medical supervision. Be aware that calcium can reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For PQQ specifically, data not available for a confident recommendation.
