Our assessment
The evidence shows that Herbalife Nutrition Active Fiber Complex Unflavored contains calcium. Our assessment is that while calcium is essential for health, you need to be careful with supplementation because high intakes carry risks. Specific data on this exact product's effectiveness is not available, so we focus on the ingredient itself.
How it works
Think of calcium as a structural builder and messenger. It supports bone mineralization by helping deposit minerals into your skeleton, and it supports neuromuscular relaxation, which is crucial for muscle function and nerve signaling [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all products. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you get your calcium primarily from food sources and only use supplements to fill a verified gap. Before taking this product, check your total calcium intake from all sources (diet and supplements) to avoid exceeding safe levels. If you take medications, especially those listed above, consult your doctor or pharmacist about timing and potential interactions [NIH ODS].
