Life Extension Fiber-Immune Support Apple-Cinnamon Flavor
Brand: Life Extension · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that this product’s primary active ingredient, calcium, is well-established for bone health, but the specific "Fiber-Immune Support" formulation lacks direct clinical trial data for the claimed immune benefits. Data on the fiber component is not available in the provided information.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, and plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as a foundational mineral that your muscles and nerves rely on to function smoothly.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high blood levels can cause poor muscle tone, kidney issues, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS].
Our recommendation
If you are using this for bone support, calcium is a well-supported choice. However, be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Separate your dose by at least two hours from these medications. For the immune and fiber claims, data is not available to support a specific recommendation.
