1st Phorm Essential Amino Acids Watermelon

Our assessment

The evidence shows that while the product you asked about contains calcium, the specific formulation of 1st Phorm Essential Amino Acids is not supported by sufficient data to make a strong health claim. For calcium specifically, our assessment is that it plays a vital role in bone health, but you must be cautious about total intake from all sources, including supplements [NIH ODS].

How it works

Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age. Additionally, calcium is essential for neuromuscular relaxation and nerve signaling, meaning it helps your muscles relax after contracting and supports proper nerve function [NIH ODS].

Safety profile

FDA received a total of 592,059 adverse event reports across all supplements, though specific report counts for this product are not available. Regarding calcium, some research suggests that high 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Data not available to recommend this specific product. For calcium, you should aim to meet your needs through food first and avoid exceeding the tolerable upper intake level from supplements. If you take calcium, do not take it at the same time as medications like thyroid hormone or certain antibiotics [NIH ODS].
