While human studies are still in the early phases, preliminary results are encouraging. A few clinical trials have reported that NMN supplementation is safe and well-tolerated, showing promise for increasing NAD+ levels in healthy individuals. However, more substantial clinical data is needed to fully understand its long-term effects and potential health benefits.
Despite their advantages, oxo-biodegradable additives also face skepticism and critique. One significant concern is that the breakdown process may not fully eliminate microplastics from the environment. Critics argue that while the additives help plastics degrade faster, they do not necessarily ensure complete biodegradability. Some studies suggest that the degradation process may leave behind small plastic fragments that can harm marine life and ecosystems. Therefore, while oxo-biodegradable plastics are a step in the right direction, they must be regarded as part of a broader strategy to combat plastic pollution.
