Allergy Research Group QuatreActiv Folate Plus
Brand: Allergy Research Group · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Allergy Research Group QuatreActiv Folate Plus contains calcium, a mineral essential for bone health, but the data provided does not specify the exact amount of calcium per serving. Based on the available information, this product is formulated to support bone mineralization and nerve signaling through its calcium content [NIH ODS]. However, without a specific dosage, we cannot confirm how much calcium you are actually getting from this supplement.
How it works
Think of calcium as a structural builder for your skeleton and a signal regulator for your nerves. It works by supporting bone density through mineralization and helps your muscles relax properly after contraction [NIH ODS]. This dual action makes calcium critical for both skeletal strength and neuromuscular function.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, though specific reports for this product are not available in the provided data. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Given that the exact calcium dosage is not listed in the provided data, we recommend you check the product label carefully before taking this supplement. If you are taking any of the medications listed above, separate your calcium dose by at least 2 hours to avoid absorption issues [NIH ODS]. For bone health, aim for the standard 1,000–1,200 mg of total calcium daily from both diet and supplements, but do not exceed 2,000 mg per day from all sources combined [NIH ODS]. Speak with your healthcare provider before starting this supplement, especially if you have a history of kidney stones, heart disease, or prostate concerns.
