Capsules vs Powders: Which Delivery Method is Best?

Supplements come in enough forms to make any consumer’s head hurt. Delivery methods are chosen for several reasons, not least of which is taste. Some nutrients break down in humid conditions and others are easier to absorb in specific forms. Your choice of powder or capsule will need to account for all of these considerations.


Protein is one of the most common nutrients to be delivered in powdered form because you would have to swallow 60 one-gram tablets daily to meet your daily requirements. Some nutrients are tasteless, but others are too unpalatable to drink. Spirulina lends itself to powder and pill forms, but vitamins A, B, and D have potent tastes and are, thus, best taken as pills.


Capsules are easily absorbed and equally convenient to carry or store. They hide flavor and protect ingredients from moisture. Some capsules are made from soft gels, which carry nutrients that are best suspended in oil. Omega 3 and vitamin A are two examples. Water-based nutrients are usually reduced to powdered form and encapsulated in traditional gelatin.


Tablets are cost-effective when synthetic magnesium stearate is used as a flow agent. Organic flow agents are more expensive and could improve the bioavailability of some supplements. Excipients hold the ingredients together, but they can also reduce absorption rates depending on dosage and the site of absorption. Capsules need fewer excipients to make the nutrients they carry easier to absorb.

Bioavailability has become a buzzword in recent years because today’s consumers educate themselves on every aspect of their health. Modern supplements must do more than merely achieve convenience. They must be effective, and your clients are likely to know how delivery choice affects your product. That’s why supplement sellers are using Healthy Solutions for their capsule and powder products. The more sellers incorporate both methods, the better.
