I've been curious about how the supplement industry works behind the scenes, especially when it comes to businesses that manufacture products for other brands. What should a company consider before choosing a B2B supplement manufacturer? I imagine there are quite a few things to think about beyond the price, such as ingredient quality, production standards, certifications, minimum order quantities, packaging, and the ability to maintain consistent quality between batches. How do businesses usually check whether a manufacturer is reliable, and what questions should they ask before starting a partnership? I'm also interested in how smaller brands manage product development and production when they don't have their own manufacturing facilities. For those who have experience in this industry, what are the most common challenges and what would you recommend paying attention to from the beginning?
