Life Extension Provinal Purified Omega-7
Brand: Life Extension · Form: SOFTGEL CAPSULE [E0161] On Market
Our assessment
The evidence shows that Life Extension Provinal Purified Omega-7 is a targeted supplement, but you should be aware that the key ingredient, calcium, is present in the formula. Our assessment is that you need to understand both the benefits and risks of calcium supplementation before taking this product. The data confirms that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural and signaling mineral — it helps build and maintain strong bones by supporting bone density and mineral deposition, and it also helps your muscles relax and your nerves send signals properly [NIH ODS]. This mechanism is central to how this supplement may support your overall health.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, 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] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to consult your doctor before taking this supplement, especially if you have a history of kidney stones, heart disease, or take any prescription medications. Be aware of your total daily calcium intake from all sources — food and supplements — to avoid exceeding safe levels. Data on the specific omega-7 component of this product is not available [NIH ODS].
