Capsules generally refer to capsules made from special film-forming materials (such as gelatin, cellulose, polysaccharides, and pure natural plant starch, etc.), which is used to enclose ingredients in a relatively stable shell, allowing them to be taken orally. The two main types of capsules are hard-shelled capsules and soft-shelled capsules. The hard-shelled capsules contain dry, powdered ingredients whereas the soft-shelled capsules primarily used for oils and for active ingredients that are dissolved or suspended in oil. The ingredients placed in the soft capsule are more restricted. In addition, the material of the capsule shell can also be made of plant material. The plant-based capsule shell is very commonly used in products for vegetarians. Generally speaking, the cost of the plant-based shell is higher than that of the animal-derived gelatin shell.
The advantages of the capsule include the ability of being effective oxygen barrier and excellent chemical stability, which could improve product stability. For example, components are unstable, sensitive to temperature, light and heat can be made into capsule forms. Moreover, capsules are good in uniformity of dosage units, and capsules can be made into different types to meet the needs.
Another common type used in dietary supplements is tablet format, which requires high pressure to help with molding. However, the pressure and temperature at the time of making could potentially damage the activity of the sensitive components. Moreover, the tablet form has to be coated with a film coat to increase moisture resistance; the composition of the coating contains a lot of chemical additives, including titanium dioxide and talcum powder. All of which have pointed out potential risks and harms. Some cheaper tablet products also used to add artificial colors on the coating, which burden our body in a big way.
Aim at the multiple advantages of capsules, REAL PROMISE’s products chose the capsule format purposely. We also emphasize on using plant-based capsules, because it has better taste due to plant-derived ingredients and natural ingredients compared to animal-derived gelatin capsules. The plant-based capsule shell is stable at low humidity levels, has low moisture content and low static charge, and is more suitable for oxygen-sensitive and immediate-release drugs. These characteristics make the contents safer, better dissolution, and more remarkable impact on the users. REAL PROMISE is also extremely careful in the choice of capsule size. The sizes of the hard-shelled capsules for the human body are divided into six types, from 00 (maximum) to 4 (minimum). In general, the size of the hard shell affects the user acceptance and compliance. REAL PROMISE selects the smallest size of the capsules, our intention is to make the product easier to swallow, thus reducing the discomfort and rejection from the users. REAL PROMISE always think best for your health, we try to stand on the perspective of the consumers, and provide the best nutritional supplementations.
