Higher Nature Sea Calcium 500 mg
Brand: Higher Nature · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is essential for your bone health, but the specific form in Higher Nature Sea Calcium 500 mg does not change the fundamental rules for safe supplementation. Our assessment is that this product can be a reasonable option if you need to boost your calcium intake, but you must be very careful with dosing and potential medication interactions [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density by depositing into your bone structure [NIH ODS]. It also acts as a neuromuscular regulator, helping your muscles relax and your nerves send signals properly [NIH ODS]. Without enough calcium, your body will pull it from your bones, which can weaken them over time.
Safety profile
Data not available for this specific product's side effects. However, the FDA has received 592,059 total adverse event reports for all calcium supplements [FDA data]. High intakes of calcium may increase the risk of heart disease and prostate cancer [NIH ODS]. Taking too much can lead to serious issues including constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High levels in your blood and urine can also cause poor muscle tone, poor kidney function, and low phosphate levels [NIH ODS].
Our recommendation
Start by checking your total daily calcium intake from food and other supplements. If you need a supplement, take this product with food and never exceed 500 mg from this single source without medical guidance [NIH ODS]. Crucially, separate this supplement from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin by at least 2 hours, as calcium reduces their absorption [NIH ODS]. Your best bet is to discuss your full medication list with your doctor before starting [NIH ODS].
