  • Why is Tanalbit a superior gastrointestinal support product?

    Tanalbit contains milk-derived complex amino acids and proteins, namely hydroxyproline and proline amino acids. The proteins "mask" the Tanalbit product and allows it to travel further into the gastrointestine, where often most support is needed. Read More...

    How does Tanalbit work?
    Tanalbit is composed of a propriety zinc and plant tannin blend called "zinc tannates".  The zinc tannates bond with the fat and protein layers of unwanted organisms forming zinc tannate-organism complexes. (Why is this important? When the zinc tannates "occupy" cellular receptors of unwanted organisms, the activity of those organisms is shut down and they cannot metabolize or replicate.) The final step occurs when these complexes are slowly digested out during normal elimination processes. Read More...
  • Refining our Formula
    We have refined the Tanalbit formula to bring you:
    • More active ingredients per capsule, including the identification of polyphenolic and tannic acid activity per capsule
    • Higher Zinc and L-Proline milligram content per capsule, supporting better metabolism of the zinc tannate complex. Please note that Zinc is bound to the tannic acid complex and is not absorbed. It is a buffer as well, reducing  potential irritability caused by tannins.
    • Smaller Suggested Dosage: With greater potency comes a more convenient suggested regimen. Instead of 9 capsules daily our suggested regimen stops at 6 capsules daily
    • Greater Efficiency: Individuals will see greater results in a shorter amount of time and as a consequence will also benefit from cost savings

    What are Tannins?

    Tannins are water soluble, polyphenolic compounds and are either hydrolyzable or condensed. Tannins have astringent and antioxidant properties. Tannins give the bitter taste to black teas, the strong taste to red wines and are a significant component of Redwood Tree bark, giving it the bark its distinctive red color.  The plant tannins found in Tanalbit are condensed tannins.

    Are Tannins taken in a dietary supplement safe?

    Yes. Tanalbit contains condensed plant tannins. Condensed tannins have antioxidant activity properties and support GI health and healing. Tannins taken as a dietary supplement, drunk as teas or in wine, eaten in fruits or food have been shown to exhibit antioxidant activity that supports a healthy body.

    Tanalbit is complexed with milk derived proteins/amino acids which allows the formula to directly target the GI tract and mitigate possible irritation caused by tannic acid. In addition, milk proteins also help to mitigate any anti-nutritive effects of tannins. Tanalbit is non-toxic and can safely be taken by a variety of individuals.

    Please note: If you are suffering from a nutrient deficiency, have malabsorption or other conditions that results in low nutrient levels (including Calcium, Iron), do not Tanalbit before speaking with your health professional or personal physician. If your physician approves use of Tanalbit, consider supplementing with a comprehensive Multivitamin.

    Does Tanalbit affect beneficial bacteria? Will it deplete minerals?

    Tanalbit will not significantaly affect beneficial bacteria levels. Often we suggest using a probiotic after a Tanalbit regimen and using a comprehensive multivitamin to ensure proper mineral balance because imbalanced flora can contribute to nutrient deficiencies.

    Are there contraindications for Tanalbit? What about side effects?

    Occasionally individuals may experience temporary constipation after taking Tanalbit. To avoid temporary constipation, increase water intake while taking Tanalbit and consider taking a Magnesium supplement. Sometimes tannins may cause nausea or upset stomach. To prevent this, take Tanalbit with a small, protein snack.

    Tannins, the active ingredients in Tanalbit, may interfere with the absorption or efficacy of some medications. They may also not be recommended for individuals with significant nutrient deficiencies or individuals with chronic maladies or under physician supervision for serious ailments. Please consult with your health professional prior to introducing Tanalbit. There are some known contraindications for tannins (general) and medications.

    Why does Tanalbit contain amino acids derived from milk?

    The complex milk proteins (casein, proline, hydroxyproline) in Tanalbit act as potent buffers. They serve to transport the Tanalbit complex past the degrading acids of the stomach into the large intestine and colon. Milk protein powder also acts to mitigate any anti-nutritive effects of tannins.

    Tanalbit contains high heat milk powder which, as a consequence of its manufacture, contains mostly denatured, less allergenic proteins. Tanalbit may therefore be suitable for those with milk sensitivity (check with your allergist first) but it is not recommended for those with milk allergies. Tanalbit will not cause problems for individuals with lactose intolerance (where the issue is milk sugar not milk protein). The milk proteins Tanalbit will neither cause nor exacerbate mycelia growth.

    If you have a milk allergy, do not take the product and consult your health professional if he or she has suggested it for you. Consider our milk-free plant tannins, Viracin, or Tabit. Viracin and Tabit may be helpful for healthy bacteria balance support and immune support.

    Why does Tanalbit contain Zinc? Is Zinc absorbed?

    The zinc in Tanalbit activates the complex and acts as a buffer. It lessens potential irritability caused by tannins and allows the complex to travel through the GI. As part of the Zinc Tannate complex, Zinc is not "available" and not absorbed. 

    Should I use Tanalbit or Viracin? When should I use them together? How about Tabit?

    Tanalbit, Viracin and Tabit rely on the astringent and antioxidant activity properties of plant tannins. Each contain different tannin extracts which themselves behave differently.

  • What is the suggested dosage for Tanalbit?
    2 capsules, 3 times daily and increase water intake two-fold. As a general rule, water will help improve digestion, eliminate toxins and prevent dehydration and temporary constipation. Dosage suggested for 4-6 weeks or as prescribed by your health professional or physician. Tanalbit performs best on a relatively empty stomach, at least 30 minutes to 1 hour before meals. If you cannot tolerate Tanalbit on an empty stomach, take your suggested dosage with  a small protein snack. If you are using Tanalbit for skin health, suggested dosage is 2 servings daily for at least 2 weeks. When taking Tanalbit for food sensitivity or indigestion, take 1 to 2 capsules right after a meal. Questions? Email our nutrition guru, Olivia Melaugh, at askolivia@intensivenutrition.com for help.

    Do not take Tanalbit after large meals or at the same time as other supplements/medications. Allow at least 1 hour between Tanalbit and other dietary supplements; Tanalbit needs to work without competition from other supplements / medications. Tanalbit works in a gradual manner hence the need for a larger dosage as well as a regimen that works throughout the day instead of all at once.

    Some basic rules: avoid excess sugar, refined carbohydrates and citrus. 

    Maintenance Program:

    A maintenance dosage is suggested after 4 weeks of Tanalbit, but please consult with your health professional before starting a maintenance program.
