What Are Probiotic Tablets

A probiotic tablet is a compressed solid form of beneficial bacteria, typically formed under physical pressure. This tableting process is an industry-documented consideration when it comes to bacterial viability. Tablets generally don't use a capsule shell, so how bacteria are released depends on their coating. Bio-K+ doesn't currently offer a tablet format; readers exploring tablet alternatives can look at the capsule line instead.

What Are Probiotic Capsules

Capsules consist of a two-piece shell that encases live probiotic bacteria in a protected environment. Bio-K+'s targeted-release technology is designed to help live bacteria survive stomach acid and reach the gastrointestinal tract intact, promoting, supporting, and maintaining digestive and immune health.† Capsules are shelf-stable and don't require refrigeration, and potency is guaranteed until the expiration date, a key part of every Bio-K+ probiotic capsule.

What Are Probiotic Drinkables

Probiotic drinkables are fermented liquid formats that deliver live and active bacteria in a food or beverage base. Bio-K+ drinkable probiotics contain 50 billion CFU per bottle, guaranteed until the expiration date, and promote, support, or maintain digestive and immune health.† They're available in dairy-based and vegan fermented bases, including rice, soy, and pea. Drinkables suit readers who prefer a food-based approach over a capsule.

Tablets vs. Capsules Compared

Capsules vs. tablets is a common comparison for readers evaluating solid probiotic formats. Tableting involves physical compression, which industry sources note can affect bacterial viability compared to encapsulation. Capsule shells provide a physical barrier that helps protect bacteria before they reach the digestive tract. Targeted-release capsule technology is designed to delay bacterial release until the appropriate section of the gastrointestinal tract. Bio-K+ has chosen the capsule format to support delivery of its proprietary strains.

Capsules vs. Drinkables Compared

When it comes to probiotic drinks vs. capsules, the right choice depends on lifestyle. Capsules are shelf-stable, convenient for travel, and easy to add to a daily routine without preparation. Drinkables are a fermented food-based format that may suit readers who prefer food sources over a capsule. Both Bio-K+ capsules and drinkable probiotics feature the same proprietary three-strain formula, backed by more than 30 years of research.

Reading a Probiotic Label

A quality probiotic label lists full strain names, including genus, species, and strain code, not just a generic family name. CFU count should be guaranteed at a specific date, ideally the expiration date, not the time of manufacture. Registered trademarks on strain names signal proprietary, researched cultures. Bio-K+ labels specify each proprietary strain with its registered trademark code and guarantee CFU until the expiration date on every capsule.

Choosing Your Probiotic Format

How to choose a probiotic format comes down to lifestyle fit. Choose a capsule format if you value shelf stability, travel convenience, and targeted-release delivery. Choose a drinkable format if you prefer a fermented food-based approach and enjoy a daily functional probiotic drink. Bio-K+ doesn't make a tablet format; the capsule line is the closest equivalent. Format availability varies by SKU across the United States, so check the product page for details.

Frequently Asked Questions

Can probiotic bacteria survive the tablet compression process?

Tablet compression involves physical pressure that industry sources identify as a potential factor affecting bacterial viability. This differs from the encapsulation process used in capsule formats, which doesn't involve the same physical force. Enteric-coated or specially formulated tablets may partially address this, though protection varies by product and coating type. Capsules using targeted-release technology are specifically engineered to help bacteria survive gastrointestinal transit.

Do probiotic capsules need to be refrigerated?

Bio-K+ probiotic capsules are shelf-stable and don't require refrigeration. This makes them practical for travel and for anyone who'd rather not manage refrigerated products. Live bacteria potency is guaranteed until the expiration date under normal storage conditions. Store capsules away from direct heat, moisture, and sunlight, refrigeration or not, to help protect the bacteria inside.

Are probiotic drinks better than capsules?

Neither drinkable probiotics nor capsules are universally better; the right format depends on individual lifestyle and preference. Bio-K+ drinkable probiotics are a fermented food-based format, while Bio-K+ capsules use targeted-release technology to deliver bacteria to the gastrointestinal tract. Both formats share the same core three-strain formula and the same potency guarantee until the expiration date. Choosing between them comes down to daily routine and personal preference.

Why don't probiotic tablets list strain codes on the label?

Many generic probiotic products list only genus and species without a strain code, which makes it hard to confirm a specific researched strain is included. Strain codes appear alongside genus and species names on Bio-K+ labels as registered trademark identifiers. A strain code is a key indicator of a proprietary, researched formulation rather than a generic bacterial culture.

Can I switch between probiotic capsules and drinkables?

Switching between Bio-K+ capsule and drinkable formats is possible, since both use the same core three-strain formula. Consistency in probiotic use matters more than the specific format you choose. If you switch formats, try to maintain the same daily routine to support consistent results. Consult a healthcare professional if you have questions about switching while managing a specific health condition.
