• Good Vendor Reputation After receiving your green maeng da kratom, you can assess it by looking at the color. Old kratom usually turns brown. Instead, fresh products can appear green. It should also have an earthy smell and taste. The product should also be dated and have a long shelf life. From our tests, New Dawn Kratom seems to be the best source of Green Meng Da with the most competitive prices on the market. They offer a high-quality product that is ethically sourced, have great customer support, and has one of the best vendor reputations in the industry. One of the main factors that sets New Dawn Kratom apart from other vendors is the higher alkaloid percentage as their green maeng da kratom is fresh.
