A tablet is another delivery form chosen by some dietary supplement manufacturers. Tablets are a cheaper manufacturing alternative to capsules, and they are often filled with harmful fillers, preservatives and unnatural additives that take away from the nutrient value of the supplement.
Tablets are compressed and contain additives to meet their requirements for hardness and stability, therefore they are more difficult for the stomach to break down and can cause gastrointestinal irritation or poor absorption of nutrients. Additionally, some tablets may be manufactured through wet or dry granulation, which can add heat or moisture to the components.
