How often should I take Viva+?

Some take Viva+ during periods of stress, while others prefer to take it on a daily basis.

Safety issues? The toxicity of the saffron extract has been tested in vivo and in vitro (Abdullaev et al., 2002).
The authors concluded that doses of up to 1.0 g/day of saffron extract are safe (=70 Viva+ tablets.)
5 grams of saffron extract (= 350 Viva+ tablets) is considered poisonous.
