Frequently Asked Questions (FAQ)

Can Shilajit and Astaxanthin be taken together?

Yes, Shilajit and Astaxanthin can be taken together. Shilajit supports energy, brain health, and hormones, while Astaxanthin provides antioxidant protection for the skin, heart, and muscles. Since they work differently, taking both can support overall wellness.

What are the potential side effects of Astaxanthin?

Astaxanthin is generally safe, but some people may experience mild digestive discomfort, bloating, or stomach upset. High doses may rarely cause a slight orange skin tint. Always talk to a healthcare provider if you have concerns.

How do Shilajit and Astaxanthin differ in their antioxidant properties?

Astaxanthin is a direct antioxidant that neutralizes free radicals and protects cells from oxidative stress. It is much stronger than vitamin C. Shilajit supports antioxidant activity indirectly by boosting nutrient absorption and mitochondrial function—which helps reduce oxidative damage.
