Radiation Protection for Bones: Antioxidant Protocol Before CT Scans

CT scans save lives, but they also come with a hidden cost: radiation damage.
Researchers now estimate that CT scans may cause 100,000 new cancers each year—about 5% of all cancers in the U.S. This is because CT scans deliver some of the highest doses of medical radiation, leading to DNA damage and long-term health risks.The good news? Canadian researchers discovered a simple antioxidant protocol that significantly reduces DNA damage when taken before a scan. Even better, the antioxidants used are the same ones that support bone health every day.

The Antioxidants That Protect Bones (and DNA)

Radiation creates free radicals, which attack DNA and weaken bone cells. Antioxidants neutralize these free radicals, reducing both DNA and bone damage. The key nutrients include:

Vitamin C (buffered ascorbate) – our favorite antioxidant for bone and immune health
N-acetylcysteine (NAC) – boosts glutathione, the body’s master antioxidant
Lipoic acid – a powerhouse for bone and cellular health
Beta-carotene – supports bone, eye, and immune resilience

The Proven Antioxidant Protocol

At Better Bones, we’ve adapted the Velauthapillai study protocol to make it simple and effective:

2,000 mg buffered ascorbate (Alkaline for Life® Alkalini-C, ~2/3 tsp)
600 mg lipoic acid (the Toronto study used this amount)
1,200 mg N-acetylcysteine (NAC)
30 mg beta-carotene

*See what lipoic acid, NAC, and beta carotene Dr. Brown recommends here: https://us.fullscript.com/plans/betterbones-radiation-protection-protocol Alkalini-C available in better bones shop.

For best results, take this protocol daily for at least five days before your scan to build antioxidant reserves. This provides maximum protection at the time of radiation exposure.

What If You Don’t Have Five Days?

Emergencies happen. Dr. Susan Brown shares her own experience: “After an accident, I needed a CT scan of my neck. I didn’t have time to prepare with the protocol. In that case, the best suggestion is to take a high dose of buffered vitamin C immediately after the scan, and add lipoic acid and NAC if available.”

While pre-scan preparation is best, post-scan antioxidant support still helps reduce oxidative stress.

When to Use This Protocol

Consider antioxidant protection for:

CT scans
DEXA bone density scans
Mammography
Other high-radiation medical imaging

Final Word: Use Scans Wisely

While CT scans and other imaging tests can be lifesaving, they shouldn’t be used casually. As Dr. Brown reminds us:
“Let’s only get CAT scans if we really need them—and protect ourselves beforehand if at all possible.”

With the right antioxidant protocol, you can dramatically reduce radiation’s impact on both your bones and your long-term health.
