Rainbow Light Performance Energy For Men
Brand: Rainbow Light · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Rainbow Light Performance Energy For Men is a multivitamin that includes calcium, a mineral essential for bone health. However, you should be aware that the data on calcium supplementation includes important safety considerations. Our assessment is that while this product can help you meet your daily needs, you must be cautious about your total calcium intake from all sources, as high levels are linked to serious health risks [NIH ODS].
How it works
Calcium serves as a master regulator for your body's structural integrity and nerve function. It supports bone density through a process called bone mineralization, and it also aids in neuromuscular relaxation, which helps your muscles relax and nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement products, though specific data for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high levels of calcium in the blood and urine include 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 medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend that you take Rainbow Light Performance Energy For Men only if your diet is low in calcium. Do not take additional calcium supplements without reviewing your total daily intake from food and other sources. Separate this supplement from any medications you take by at least two hours to avoid absorption issues [NIH ODS]. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before use [NIH ODS].
