When it comes to the vitamin and supplement industry, selecting the right manufacturer can make all the difference in the success of your business. In this guide, we outline the key factors you should consider when choosing a manufacturing partner for your vitamins and supplements.


Manufacturing capability

A reliable manufacturing partner should possess the expertise and experience necessary to produce your product range with precision and consistency. They should have the expertise and experience to not only produce your current products but should also be skilled in a range of manufacturing capabilities should you need to adjust to market trends.

For example, you may notice a pivot in the market from Vitamin C tablets to Vitamin C chewables and decide to update your range.
