Our assessment
The evidence shows that Shaklee Shaklee Fiber Plan Unflavored contains calcium, which is a mineral essential for bone health. However, the data on calcium is nuanced and requires careful consideration. Our assessment: while calcium is necessary, you need to be aware of the specific risks and interactions associated with supplementation, as the benefits are not without potential downsides [NIH ODS].
How it works
Think of calcium as a structural builder and a cellular messenger. It supports bone mineralization, which is the process of depositing minerals into your bone matrix to maintain density and strength. Additionally, calcium plays a critical role in neuromuscular relaxation, helping your muscles contract and your nerves transmit signals properly [NIH ODS].
Safety profile
Safety data is critical here. The FDA has received a total of 592,059 adverse event reports for products in this category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium in the blood and urine can lead to 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].
Our recommendation
Our recommendation: do not exceed the established upper limits for calcium from all sources. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these medications, take your calcium supplement at a different time of day. Data not available on the specific dosage of calcium in this product, so you must consult the product label and your healthcare provider before starting [NIH ODS].
