The Primary Ingredient Is: Robuvit Oak Wood Extract

Robuvit oakwood extract is a plant-based polyphenol supplement ingredient standardised to provide bioactive compounds called roburins that help cellular energy processes.

This form is sourced from French oak timber and is standardised to deliver 80 mg of total polyphenols per capsule, with Robuvit recognised as a registered extract used to support energy-related cellular activity.

What Does Robuvit Do?

Robuvit contributes to ribosomal biogenesis, the production of ribosomes involved in protein synthesis essential for energy metabolism. It participates in upregulating genes linked to ribosome production, helping to support normal cellular energy function.

In line with general dietary guidance, this mechanism helps to support energy maintenance and daily wellness through its role in fundamental cellular processes.
