Allergy Research Group QuatreActiv Folate Plus
Brand: Allergy Research Group · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Allergy Research Group QuatreActiv Folate Plus contains calcium, a mineral essential for bone health. However, the data on calcium is nuanced, and we must be careful about dosing. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. For you, the key is ensuring you are not exceeding recommended intake levels without medical supervision.
How it works
Think of calcium as a structural building block for your skeleton. It supports bone density and mineral deposition, which is critical for preventing fractures as you age. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for this specific product's adverse events. However, for calcium supplements broadly, the FDA has received 592,059 total adverse event reports across all supplements. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are taking this product, be aware of total calcium intake from all sources. Check for interactions with any prescription medications you take. Do not exceed the recommended daily allowance without a healthcare provider's guidance. If you experience constipation, nausea, or unusual tiredness, discontinue use and consult your doctor [NIH ODS] [FDA data].
