Understanding Strontium: Normal vs Optimal Ranges

?What is Strontium?

Strontium is an alkaline earth metal chemically similar to calcium. It naturally occurs in food and water and accumulates in bone. Strontium ranelate was used as an osteoporosis treatment. Radioactive strontium-90 from nuclear fallout is a significant health concern as it incorporates into bone.

!Why It Matters

Stable strontium at environmental levels is generally low-risk. High strontium exposure can compete with calcium in bone formation, potentially affecting bone quality. Radioactive Sr-90 causes bone marrow suppression and increases leukaemia risk. Serum strontium is relevant in occupational or environmental radiation exposure monitoring and bone health research.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

• Stable strontium toxicity: rare; possible bone pain or mineral imbalance at high levels
• Radioactive Sr-90: increased cancer and leukaemia risk

How to Improve Your Levels

• 1Limit environmental exposure near industrial strontium sites
• 2Adequate calcium intake may reduce strontium absorption in the gut

When to Test

Environmental or occupational strontium exposure assessment; research settings; nuclear fallout monitoring.
