Marvel Comics loves a trio of superheroes. There’s Captain America, Thor, and Iron Man as the Avengers Prime, and the original Defenders — Namor, Hulk, and Doctor Strange.

Your health loves a trio of superheroes too. The combination of vitamin D3, omega-3s, and strength-building exercise is powerful enough to cut your risk of developing invasive cancer after age 70 by 60%.

A new multinational randomized, controlled trial published in the journal Frontiers of Aging looked at the impact of taking 2,000 IU a day of vitamin D3, taking 1 gram of omega-3s, and doing a simple at-home strength-building exercise routine at least three times weekly.

Among the more than 2,000 participants who were tracked from 2012 to 2017, only four people who followed all three of the recommended interventions developed cancer, while 12 who followed none of them were diagnosed with cancer.

The benefits of doing any one of the treatments or combining two of them were measurable, but not nearly as powerful as the trio together.

Here’s what to do:

1. Perform stand-to-sit exercises, one-leg balance exercises, elastic resistance bands, or going up steps. Exercise helps fight cancer by improving immune strength.

2. Ask your doctor for a blood test to check your vitamin D levels. Then take the prescribed amount of D3 to build your immune and bone strength (2,000 IU in the study).

3. Get omega-3 fatty acids from salmon, anchovies, herring, and sea trout, and supplements made from algae or fish oil (1,000 mg in the study). These heart-loving fats may actually promote cancer cell death.
