Amazon or PromoFarma for ZMA: which is better value per capsule
The short answer. For ZMA, Amazon lists 26 products and PromoFarma another 9. By price per capsule, Amazon’s median is €0.211/capsule and PromoFarma’s is €0.234/capsule. The highest scoring across both catalogues is HSN ZMA Zinc Magnesio Vitamina B6 EvoZMA | 120 Cápsulas Vegetales | con 1000 mg Ácido D-Aspártico | Suplemento Deportivo Vegano y Sin Gluten | No-GMO from Amazon, with 74 out of 100 at €0.099/capsule. Neither has products at verification level 4: for ZMA the ceiling today is a lab report published by the brand itself, and that is not a certification.

† Some links are affiliate links — they do not change the ranking
Some store links are affiliate links: if you buy through them, this site may earn a commission at no extra cost to you. It changes nothing in the ranking: the score is computed beforehand and without reading those links, and products with no affiliate programme appear exactly the same. How it is calculated.
