Strontium Citrate 227 mg by Pure Encapsulations

Strontium citrate is worth considering if your DXA scan shows low bone density or your trend is slipping despite adequate calcium and Vitamin D, 25-Hydroxy. It’s a pragmatic option for postmenopausal women, men over 50 with osteopenia, and those who can’t tolerate or won’t use prescription osteoporosis drugs. If you’ve had a recent low-trauma fracture, discuss adding strontium citrate with your clinician alongside lifestyle, calcium, and vitamin D. For established deficiency of vitamin D, correct that first, then layer this in.

Strontium is a calcium-like mineral that gets incorporated into bone crystals and shifts bone turnover toward building. It nudges osteoblasts (the cells that form bone) to be more active and reins in osteoclasts (the cells that break bone down), which can raise measured bone density within a year. The catch is that DXA can overestimate gains because strontium blocks X-rays more than calcium. Track bone turnover markers like P1NP (bone formation) and CTX (bone resorption) to gauge true biology, not just imaging.

Pure Encapsulations provides 227 mg per capsule; most clinical programs use about 680 mg elemental strontium daily, which is three capsules. Take it in divided doses or once at bedtime, away from calcium-containing foods or supplements by at least two hours so it absorbs properly. Keep calcium and vitamin D steady in the background, then recheck DXA after 12–24 months and consider P1NP/CTX at 3–6 months to confirm direction.

Take strontium citrate at least two hours apart from calcium, iron, magnesium, or zinc, and separate it by several hours from levothyroxine and from antibiotics like tetracyclines or quinolones so those drugs absorb. If you have chronic kidney disease, a history of heart attack or stroke, or uncontrolled high blood pressure, review strontium use with your clinician; cardiovascular safety signals came from a prescription form in high-risk patients. Pregnancy and breastfeeding: avoid.

Most people won’t feel anything day to day; this is about long-term structure. P1NP and CTX can shift within 3–6 months, while meaningful DXA changes take 12–24 months. Strontium citrate does not replace calcium or vitamin D, it works alongside them. If your Vitamin D, 25-Hydroxy is low, correct that first so bone-building signals have the raw materials they need.
