    Zest Active is Keto friendly. You should take your Zest Active with water as opposed to in a smoothie or fruit juice and should take it just before one of her meals.

    As long as you take Zest Active with water and not a juice or a smoothie, you are perfectly able to take it anytime, it does not have to be in your eating window. The calorific value of Zest Active is 6 kcal, so is negligible in the scheme of things. If, however, you were to have your Zest Active in a smoothie or with a full sugar drink or fruit juice, I would take it within my eating window.

    Zest Active contains Wellmune & selenium enriched yeast. Both are produced from deactivated yeast and the yeast is inactive in the final product. It should not cause you any problems if you are suffering from yeast intolerance or if you are trying to avoid yeast.

    Elite athletes can safely take our product as each batch has been tested against WADA prohibited substance list and found to contain no prohibited substances. All testing is carried out independently of Revive Active

    Revive Active and Zest Active are both suitable for adults aged 18 and over, however, Revive Active is tailored for those over the age of 35 as it contains additional ingredients targeted at heart health. Zest Active unlike Revive Active, contains an additional ingredient Wellmune®,a beta glucan by the Kerry Group, along with the eight other ingredients that contribute to the normal function of the immune system - Zinc, Copper, Folate, Selenium Vitamins B12, B6, C, and D.

    Both products contain similar ingredients that contribute to the reduction of tiredness and fatigue, ingredients such as Vitamins C, B12 and B6 to name but a few but Revive Active contains CoQ10 which is critical for cellular energy and depletes naturally as we age. To summarise, Revive Active is tailored to suit the healthy aging demographic, whereas Zest Active is targeted more to a younger age demographic who are trying to juggle a busy work schedule, daily fitness regime and an active social life.
