Supplement Ingredient Quandary Solved

From eNewsletter 7/22/2026

Steve: Titanium dioxide, the ubiquitous whitening agent, has been used for decades in food and non-food objects. There are two forms: regular titanium dioxide and nanoparticle titanium dioxide.

We are vehemently against the use of nanoparticle titanium dioxide in all products. Even sunscreens that contain it are dangerous because it is so small it can get beyond the dermal layers and into cells around the body.

Until recently, our opinion on regular titanium dioxide was agnostic. The safety data is now questionable enough that we are recommending against ingesting foods and supplements with titanium dioxide unless no other alternative exists. Regular titanium dioxide is still okay topically in sunscreens and body care products.

We found ourselves in a quandary with Ecological Formulas Vitamin C 1000 because it contains titanium dioxide. There are literally only two non-corn-based vitamin C supplement options on the market. The alternative is a cumbersome tablet and expensive. Luckily, the issue has been resolved. After constantly badgering the powers that be at Ecological Formulas, I can happily say that they have removed the titanium dioxide going forward :)

Don't Rely on the Sun for This

From eNewsletter 7/20/2026

DID YOU KNOW that you should not rely on the sun, even in warm weather climates or summers in cold climates, for vitamin D sufficiency?

Researchers publishing in the European Journal of Clinical Nutrition found that a significant number of people have low vitamin D year-round without realizing it, potentially affecting bone health, overall well-being, and long-term health outcomes.

The study focused on adults aged 65 and older as well as people from minoritized ethnic backgrounds of all ages. The researchers found that vitamin D insufficiency was common in both groups.

Most notably, vitamin D levels did not improve during the summer months. This finding runs counter to the common assumption that increased exposure to sunlight during summer is enough to bring vitamin D levels back into a healthy range. This is because very few people stay in the sun for 15 minutes or more per day with 75% of their skin exposed without sunscreen.

Best Fruit for Bone Loss

From eNewsletter 7/15/2026

DID YOU KNOW that prunes are one of the most effective fruits for preventing and reversing bone loss?

A study from Frontiers in Nutrition reviewed existing data and found skeletal benefits associated with consumption of 50-100 grams of prunes, particularly at the lumbar spine based upon trabecular scores.

This is important because trabecular score gauges bone quality, which is more important than quantity.
