Kyolic Kyolic A,C, E & Herbal Antioxidants

Our assessment

The evidence shows that Kyolic Kyolic A, C, E & Herbal Antioxidants contains the mineral Calcium as a key ingredient. Our assessment is that this product may support bone health, but the available data for its specific formulation is limited, and you should be aware of the potential risks associated with calcium intake. We will base our analysis strictly on the data provided.

How it works

Calcium works in your body through two primary mechanisms. First, it supports bone mineralization by helping to build and maintain bone density and mineral deposition. Second, it aids in neuromuscular relaxation by supporting proper muscle relaxation and nerve signaling [NIH ODS]. For this specific product, data on how the other herbal and antioxidant ingredients work together is not available.

Safety profile

The FDA has received a total of 592,059 adverse event reports for all products, but data on how many of these reports are specifically for this Kyolic product is not available. For the calcium component, safety data shows that high intakes might increase the risk of heart disease and prostate cancer. 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Before starting this supplement, you should review the product label for exact dosages, as data for the specific amounts of each ingredient is not provided. Given the potential for calcium to interact with medications, you must consult your doctor or pharmacist, especially if you take any of the medications listed above. We recommend prioritizing calcium from food sources and only using supplements like this one under professional guidance to avoid high intakes that carry significant health risks [NIH ODS].
