Vitamin Supplements – Why Injections Are Better than Oral

Years ago, a reputable consumer watchdog company did an intensive study on the purity and effectiveness of 1,600 oral supplements. Of all the tested products, 25% were proven to be sub potent and/or contaminated. Because the FDA is has no responsibility over oral vitamin supplements, manufacturers are left on their own as to the quality of such products. On the other hand, vitamin Injections only contain ingredients approved by the the United States Pharmacopeia-National Formulary (USP-NF).

The following are the exact advantages offered by vitamin injections:

More Efficient Absorption and Bioavailability

Oral supplements first need to be digested and absorbed by the body’s tissues before their active ingredients start taking effect. Additionally, poor quality nutrients and cheap fillers can reduce the supplements’ bio-availability (how much of the supplement actually benefits the body), considerably diminishing intestinal absorption, leading to indeterminable levels of the active ingredients making it to the the bloodstream. However, vitamin Injections directly transport nutrients into the body’s tissues, ensuring hundred percent absorption and utilization of active ingredients on-the-spot.

Requires No First-Pass Metabolism

The moment oral supplements are reach the digestive system, they go through a heavy metabolic process before they are released into the blood for systemic circulation. Called first-pass metabolism, this process eats away at the amount of active ingredients that the body can actually use and benefit from. In contrast, the first-pass effect does not apply to vitamin injections because the active ingredients are delivered straight into the bloodstream.

Rapid Effects

As mentioned in the previous paragraph, oral supplements have to go through an entire process before getting into the bloodstream, and this can take hours before the active ingredients start to act on the target tissues. Compared to the oral route, injectable vitamin supplements can correct dietary deficiencies drastically faster.

Lower Dosing Frequency

Due of their low bioavailability and the extensive metabolic process they must go through, oral supplements need to be dosed frequently so they can be effective. As they do not need to undergo the same process, vitamin injections are fully absorbed, meaning the concentration of nutrients that arrive in the tissues is higher. As well, intramuscular injections have a depot effect, where which the supplements’ active ingredients are released slowly but steadily within a period of time. Hence, compared to oral supplements, injectables need less frequent dosing.

Summary

Compared to oral dietary supplements, vitamin injections are better because of their superior quality ingredients, which do not include fillers or contaminants, and higher potency. Right after administration, the active ingredients are totally absorbed by the bloodstream for systemic circulation, correcting nutritional deficiencies instantly. And due to the depot effect and more nutrients getting into target tissues, vitamin injections require less frequent doses to be effective.
