Capsules and liquid formulas can be easier to absorb than tablets. When taking a multi-vitamin or B complex, your urine will turn a very bright (almost fluorescent) yellow once it has been absorbed. In general, this process should occur within an hour of taking the supplement. If your urine doesn’t turn yellow, it could mean that your body is having difficulty absorbing that particular supplement (meaning, you may have not produced sufficient stomach acid to dissolve it).
Since each person’s metabolism is different, it is virtually impossible to predict a specific absorption time. Age, health, and activity levels are a few factors which contribute to absorption of a supplement. Some supplements may take up to six hours to disintegrate in your body.
Products in tablet form tend to contain more excipients and fillers. Manufacturers make tablets because they are cheaper and more of the raw materials can be compressed into one pill than capsules. However, this compression produces heat which can destroy some of the active ingredients. Moreover, capsules are much easier to swallow and digest than tablets. Tablets can typically require seven different excipients. Capsules allow for more of the active ingredients to be absorbed by the body than tablets. Endeavor to buy products as close to nature as possible.
