Yes, the products can be taken individually or in combination with each other, depending on the effect you want.
We recommend the following combinations:
FOKUS (2 pcs. morning) +RO (2 pcs. evening)
RO (2 pcs. morning or evening) + FOKUS (2 pcs. morning)
MÆT (2 pcs. morning or evening) + FOKUS (2 pcs. morning)
IMMUN (2 pcs. morning) + FOKUS/RO/MÆT (2 pcs.)
If you combine the products, we still recommend that you take 2 capsules of each to achieve the full effect. As all bodies are different, we have also experienced that some get the full effect by taking just 1 capsule of one product or of both products when combined. We would always encourage you to test how your body reacts.
