Essential amino acids

Essential amino acids (9 types of which we know) are essential for the human body because they are not or only insufficiently produced by the body. That is why it is particularly important to supply them from external sources, preferably in the optimal amount and proportion.

Question CBD (Translated by Google)

Hello . (+ 1kerdes)
CBD oil can be taken next to it?
thanks... (Translated by Google)

Yes, can be taken! (Translated by Google)

Question Melatonin (Translated by Google)

I would have a question of coming from this next to Melatonin (1mg)?
And before bedtime, how long do L-tryptophant be taken? (Translated by Google)

Together, I do not recommend the two, and Tryptophan is worth taking it half-1 hour before bedtime. (Translated by Google)

Medication (Translated by Google)

Unfortunately didn't come in. Do not replace the medicine at least! SSRI was taking medicine for a long time (antidepressant) that psychiatrist writes up, but this product did not bring the same. Damage. :( (Translated by Google)
