Health Benefits & Sources
Why You Need It
- Internal Sun Protection: Acts as a natural supplement to reduce UV-induced skin damage.
- Antioxidant Powerhouse: Neutralizes free radicals that cause aging and cellular stress.
- Skin Health Support: Helps prevent sunburn, reduce redness, and maintain skin elasticity.
Deep Dive
Polypodium works primarily by providing your body with a concentrated dose of phenolic compounds and antioxidants. When you take it, these compounds circulate in your blood and reach your skin cells.
- UV Defense: It is clinically proven to reduce the inflammatory response caused by UVB rays, effectively minimizing the severity of sunburns. It doesn't replace sunscreen, but it adds a layer of defense.
- DNA Repair: It helps protect the DNA within your skin cells from mutation caused by sun exposure, which is crucial for preventing long-term damage.
- Immune Support: It prevents the suppression of the skin's immune system (Langerhans cells) that usually happens after sun exposure, keeping your skin's defenses fully operational.
Natural Food Sources
Unlike common vitamins found in oranges or spinach, Polypodium Leucotomos is exclusive to the fern plant. You cannot get a therapeutic dose from your diet alone. However, you can support the supplement's effects by eating foods rich in general antioxidants.
| Food | Amount | % DV |

Supplementation
Since this is a specialized botanical extract, supplementation is the only way to get the benefits.

- Who Should Take It: People who are photosensitive, those with a history of skin cancer, or anyone looking for extra protection against sun damage and photoaging.
