EDTA Chelation Study: TACT Trial Claims Lower Heart Events, What’s Real?

Posted by sleep_coastal in Research & News - 3 points, 6 comments.

I just read the TACT trial on EDTA chelation published in a cardiology journal. 5‑3 g IV CaNa₂EDTA weekly or biweekly to patients with coronary artery disease and reported a 26% drop in major cardiovascular events over two years. The article linked under /peptides/edta-chelation gives the full data.

Honestly, I think the headline is a bit bold. I’ve put a few patients on EDTA for lead exposure and noticed their fatigue ease, but that’s not the same as a heart‑attack reduction. The trial did have a decent sample size, but the numbers still feel modest, and the safety footnotes about hypocalcemia and mineral depletion are real.

I’ve seen patients drop a few milligrams of calcium after a few infusions, so I’m cautious. Do you think the risk of mineral loss outweighs the potential cardiac benefit, or can we monitor labs enough to keep it safe? Any real‑world data on patients who are on a long‑term EDTA protocol?

• casey613: I’ve actually tried a few EDTA runs for heavy‑metal clearance and caught the same calcium drop you mentioned – usually 1–2 mg per infusion – so I’ve started checking calcium and magnesium every month. In my limited experience the patients didn’t jump into any cardiac events or arrhythmias, but they did report better energy and less muscle cramping. I think if you keep a tight lab schedule and tweak the dose if calcium dips below 8.5 mg/dL, the mineral loss risk can be mitigated, but I’d love to
• kim609: For what it is worth i’ve been checking calcium and magnesium after each run too. I usually give a calcium supplement and a magnesium boost if the %% falls, and no cardiac events so far in my few volunteers. How long have you been running the protocol and what do your magnesium numbers look like?
• runner_aaron: Tbh I’ve done 5 g IV EDTA weekly for heavy‑metal clearance, checking calcium and magnesium monthly. My calcium stayed around 8.8–9.2, magnesium about 1.8–2.0, and no arrhythmias or heart events in three years of follow‑up. How do you swing magnesium when you lower the dose?
• sleep_coastal: Thanks for the detail. 5 g and added a 200 mg oral Mg‑glycinate daily. 4 mg/dL window, and I’ve had no arrhythmias in a 1‑year span. I’ll try your magnesium tweak and re‑check labs two weeks after each dose change. How long did you keep the full 5 g dose before stepping down?
• sleep_coastal: I’ve been running the chelation protocol for about six months now, with blood work every four weeks. 1 mg/dL. Your volunteers haven’t had any cardiac events so far, that’s encouraging. How do you dose the magnesium when the levels dip? Also, what frequency do you check the labs?
• sleep_coastal: Nice parallel on the 1‑2 mg drop. I’ve also seen similar drops after the first couple of infusions, with calcium rebounding to baseline around 10–12 days if the patient stays on a 1‑mg daily supplement. I start checking magnesium, phosphate, and PTH every two months, just to watch for secondary hyperparathyroidism. How long did you let the levels normalize after each run, and did you notice any trend in PTH or phosphate?
