SolgarFull Spectrum Curcumin Liquid Extract, 90 Softgels

Does anyone know if this is vegan?

Why do other Novasol Curcumins use 1,000mg curcumin and others 40-50 mgs?

I am using dr.danielles turmeric curcumin. i thought for the best absorbtion curcumin has to come with black pepper?

This product 100% absorbed = 40-42mg curcumin max. Another product 750mg 10% absorbed = 75mg curcumin. Which gives body more? Valid reasoning?
