Sunwarrior Liquid Light With Magnesium, Silica, Selenium & Zinc

Our assessment

Our assessment: This product combines several minerals that support foundational body functions. The evidence shows that the calcium in this formula is critical for bone density, but you should be aware of the specific risks associated with high intake levels [NIH ODS]. The total number of FDA adverse event reports for this product's ingredients is 592,059, though this number covers all products containing these ingredients, not just this specific brand [FDA data].

How it works

Think of the minerals in this supplement as team players — each has a specific job. Calcium supports bone mineralization and neuromuscular relaxation, meaning it helps your bones stay dense and your muscles relax properly [NIH ODS]. The formula also contains magnesium, silica, selenium, and zinc, which work together to support various enzymatic reactions and structural health in your body.

Safety profile

Safety profile: You need to be cautious with calcium intake. 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. The FDA has received 592,059 adverse event reports total for products containing these ingredients [FDA data].

Our recommendation

Our recommendation: Do not exceed the total daily calcium recommendation of 1,000–1,200 mg from all sources (food and supplements combined). Take this supplement with food to improve absorption and separate it from medications like thyroid hormone, antibiotics, and bisphosphonates by at least 2 hours [NIH ODS]. Data not available on the specific dosage of each mineral in this product, so check the label carefully before starting [See label].
