Alison,

Here’s some relevant information provided on the Heliocare site:

—

Q. When does Heliocare Oral start to be active?

A. The protection is active half an hour after taking the capsule.

Even though the product’s activity is immediate, we recommend starting taking Heliocare Oral a few weeks before the major sun exposure periods.

Q. How long does the protection last?

A. Clinical studies performed in Boston suggest that the protection offered by Fernblock™ is still active at 2.5 hrs after the systemic administration.

We have no experimental data on the activity beyond 2.5hrs. However, the protection against histological damages was very significant at 2.0 hrs evaluation and this may suggest a longer lasting protection from subclinical damages (histological protection is being considered among the scientific community as much important as the one against clinical erythema).

Additional studies will be performed.

Be well!

Do you only take the Heliocare on days you are going to be in the sun?

Iggy,

I got a reply back re: the Vitamin D issue.

Here’s what they conveyed to me:

“According to the researcher who developed the product, it works mainly by antioxidant activity. It is not expected to interfere with vitamin D conversion.”

Be well!

That’s a great question, Iggy.

I’m not sure anyone knows for sure.

I sent your question to the leading manufacturer of such a product. Hopefully they’ll get back to us. If they do, I’ll report back.

Be well!

I’m curious if the fern extract interferes with vitamin D synthesis?

Thanks, David! How is that product working out for you?

When I was researching fern I found some really interesting studies that even show neurological benefits. It seems like it’s potential hasn’t been fully tapped as of yet.

I just noticed that the shampoo I use contains fern extract as well! I guess manufacturers are starting to take note of this ingredient. Hopefully that trend will continue.

Be well!
