Are these alternatives therapeutically equivalent?

Generics with the same INN have the same active substance and are assessed by the European Medicines Agency (EMA) for bioequivalence. Differences appear in the excipients (relevant for patients with specific food allergies — e.g. lactose), the brand and the manufacturer. Even so, the decision to switch rests with the doctor or pharmacist; do not change a chronic treatment without consultation.

Can I replace GNC - Isomer E 400UI 90cps with a generic without consulting the doctor?

For OTC (over-the-counter) medicines you can ask the pharmacist for an alternative with the same INN — this is accepted practice.

Generic vs original — in short

Generics contain the same active substance (INN) as the original product, at the same dose and in the same pharmaceutical form. To be authorised they must demonstrate bioequivalence — that is, a similar pharmacokinetic profile (the blood concentration over time is within ±20%). Typical differences are in the excipients (relevant for patients allergic to lactose, gluten or colourings), the brand and the manufacturer. For chronic treatments, switching from one generic to another is done with the doctor's agreement — even if the active substance is identical, individual tolerance can differ.
