But outside of these scenarios, there’s really no basis to assert that a quality name-brand supplement tablet can not or will not break down and be completely absorbed when taken as directed.The technology of capsule and tablet manufacture has grown and evolved with the product-side of industry; considerably more goes into making a good multivitamin capsule or tablet than simply compressing ingredients in a machine. For example, name-brand and all reputable contract manufacturers test and re-test their products for acceptable dissolution times and thoroughness under stomach-like conditions.Then there’s the old wives’ tale about the worthlessness of vitamins because “they just make expensive urine” or “you just pee them out” or other variations on the theme.
It’s not hard to see where this one came from. Anytime you take a multivitamin or a B complex, you’re going to get some vitamin B2 (Invalid Link Removed). B2 markedly changes the color or urine, usually making it much yellower. Thus when someone visit the bathroom an hour or so after taking their supplement, it’s easy to see why they might conclude that their vitamins have been wasted and have not been absorbed.
But neither is the case. Vitamins from supplements are absorbed the same way as vitamins from food; they have the same fate. No vitamin, whether from food or supplements, can go directly from the stomach to the bladder. The only way vitamins can change the appearance of urine is if they have been filtered from the bloodstream by the kidneys, and the only way that can occur is if the supplement has been absorbed from the digestive tract, and the only way that can occur is if the supplement breaks down easily or is otherwise manufactured to be Invalid Link Removed.
So, contrary to the myth, when you see color changes in your urine associated with your supplement, it’s not evidence of it being wasted, it’s confirmation that it’s been broken down, absorbed and made available to body tissues.
One final point about absorption; faster isn’t necessarily better. Many people spend the extra money for liquid supplements based on a belief that they will absorb faster than capsules or tablets. They might, but the time difference between complete absorption of liquids versus other forms, 20-30 minutes, does not amount to a noticeable advantage or a nutritional advantage with most supplements. In fact, where higher potencies are concerned, slower absorption may be preferable to fast, sudden absorption. This is because there are limits to how fast and how much of a given nutrient can be absorbed per unit of time. When you overwhelm these absorption pathways, you do waste nutrients. Slower is better when it comes to essential nutrients. Many supplements are available in time-released format for this reason. For other types of supplements such as Invalid Link Removed or Invalid Link Removed the faster absorption makes a significant difference, and has led to market dominance of these formats.
The idea that faster absorption is better comes from, we think, advertisements about medications, both prescription and OTC. When it comes to medications, especially pain medication, faster definitely is better. But it’s important to avoid applying drug-type standards to supplements. Both types of products may appearsimilar, but are as different as a farmer’s pesticides are to his fertilizer.
Now onto the different supplement formats.
Tablets are the most cost-effective supplements in general because they are less-expensive to manufacture than other formats. Tablets allow the manufacturer to pack the most material into a given space. From the manufacturing standpoint, tablets are the most shelf-stable choice and retain their potency over a longer time than liquids, powders and most capsules. Tablets can be offered in the widest range of sizes and shapes. And as long as you stick with a name-brand product and take it as directed, you needn’t worry about absorption issues with tablets. Drawbacks to tablets? Large tablets can be hard for some people to swallow. Tablets don’t offer the flexibility of dosing that liquids and powders do.
Caplets are simply tablets that have a smaller size and smoother-coating, making them as easy to swallow as capsules without giving up the other advantages of tablets. There are far fewer products offered in caplet form than tablets, however. In every other respect, caplets are similar to tablets.
Capsules refer to the familiar two-piece gelatin capsules that are widely used in supplements and some medications. Their main advantages are their easy-to-swallow characteristics and their ability to break down quickly in the stomach, although, again, not to the point that there’s any nutritional advantage. Vegetarian capsules, of which VegiCaps are the best-known brand, are a gelatin-free alternative rapidly gaining popularity as customers become more hesitant to consume meat by-products like gelatin. Some people like the fact that they can open up capsules and, using all or part of its powdered contents, mix the nutrients into applesauce or a protein shake, for example. That can be a great aid to children or others who have difficulty swallowing pills. The drawbacks of capsules? They cost considerably more than tablets. They have significant space and potency limitations since their powdered contents cannot be compressed to a significant degree. Since capsules are not air-tight, their shelf-life is shorter than tablets. They are not suited to liquid or oil-based nutrients either unless special, expensive encapsulation techniques and products are used.
