Herbalife Nutrition Active Fiber Complex Apple

Our assessment

The evidence shows that Herbalife Nutrition Active Fiber Complex Apple is a dietary supplement that contains calcium as a key ingredient. Our assessment is that while calcium is essential for your health, the specific benefits and risks of this product depend entirely on your individual dietary needs and current calcium intake. Data on the complete formula is limited, so we focus on the known ingredient.

How it works

Think of calcium as a building block for your body. It supports bone mineralization, which is the process of depositing minerals into your bone matrix to keep them strong and dense. Calcium also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after they fire [NIH ODS].

Safety profile

The FDA has received 592,059 total adverse event reports across all dietary supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium in your 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]. Please note that specific side effect report counts for this product are data not available.

Our recommendation

We recommend you calculate your total daily calcium intake from all sources—food, water, and supplements—before adding this product. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these, separate your supplement from your medication by at least two hours. Start with a low dose and monitor for any digestive discomfort. For personalized advice, consult your primary care provider or a registered dietitian.
