No supplement is intended to treat, cure, or prevent disease.

Cigarette smoking is known to cause cell damage from free radicals (unstable molecules made as cells metabolize).

This cell damage is a known risk for many health conditions, including heart disease and cancer.

However, any gastrointestinal upset, including diarrhea or cramping, should resolve with discontinued use.

The risk of vitamin C toxicity even at large doses is low.

Camu camu is found in powder, puree, pulp, capsule, and juice forms.

It may help in reducing inflammation, contributing to heart health, and in fighting post-viral fatigue.

It can also be helpful in managing blood sugar levels.
