It is best to avoid drinking caffeine one hour either side of taking your Smart Supplement.

This is because research has found that the polyphenol content of caffeinated drinks/food can inhibit the absorption of dietary iron by between 30 - 60%. The research around this is inconclusive and consensus has not been reached. Therefore, it is not definite that caffeinated products alongside your Smart Supplement will hinder the absorption of iron in the capsule.

If you are asking our advice, then we suggest giving your body the best chance of absorbing 100% of the nutrients in the Smart Supplement. Therefore, wait one hour post Smart Supplement for that morning coffee! For what it’s worth - Smart Supplement aside - it’s better to let your circadian rhythm kick in to wake you up naturally in the morning, before employing the caffeine kick for a helping hand, in any case!
