Are You Absorbing Your Supplements?

 

What is Bioavailability?

Bioavailability refers to the proportion of a substance that is absorbed into the body.

Several factors influence bioavailability:

The Form of the Supplement:

• Intravenous injection: Delivered directly into the circulatory system, bypassing the digestive system.
• Topical: Includes creams, patches, and liquids applied to the skin, also bypassing the digestive system.
• Sublingual: Drops held under the tongue for absorption via sublingual veins.
• Powder: Such as protein powders or functional foods.
• Capsule: A capsule supplement refers to a form of dietary or nutritional supplement that is encapsulated in a small, cylindrical-shaped shell or container, typically made of gelatin or plant-based materials. The capsule serves as a convenient and easy-to-ingest delivery method for various nutrients, vitamins, minerals, herbs, or other bioactive substances.
• Tablet: The least bioavailable form, requiring consideration of its absorption rate.

Solubility:

The ease with which a substance dissolves in the body impacts its absorption. For example, Centrum, which is known for its poor solubility, contrasts with highly absorbable health supplements from brands like Platinum Health Products.

Particle Size:

Smaller particles are absorbed more efficiently. This concept is exemplified by the comparison of granulated sugar to frosting. The process of reducing large molecules into smaller ones is termed “nanoparticalization,” a word that is challenging to use in casual conversation.

Duration in the Body:

Substances that remain in the body longer have a greater chance of being absorbed. Therefore, some companies create time-released versions of supplements like vitamins B and C to prolong their presence in the body.

Excretion Rate:

Substances entering the body often pass through the liver, which works to eliminate them quickly. Slowing down this process can extend the duration a substance stays in the body.

Complementary Ingredients:

Pairing certain ingredients can increase the bioavailability of the primary substance. For instance, curcumin, a component of turmeric, has low bioavailability on its own. However, when combined with phosphatidylcholine, the effects are achievable with a much smaller dose.

 

Practical Application of This Information:

When it comes to selecting health supplements, it’s crucial to be discerning and prioritize quality. Here are some key criteria to consider when making your decision:

1. Ingredients Transparency:
   • Opt for supplements with transparent and clearly listed ingredients. Avoid products with proprietary blends that don’t specify individual component amounts.
2. Purity and Quality:
   • Look for supplements that are third-party tested for purity and quality. This ensures that the product meets the stated standards and doesn’t contain contaminants.
3. Bioavailability:
   • Consider the form of the nutrients in the supplement. Some forms are more easily absorbed by the body, increasing their bioavailability and effectiveness.
4. Additives and Fillers:
   • Avoid supplements with unnecessary additives, preservatives, or fillers. Choose products that are free from artificial colors, flavors, and sweeteners.
5. Allergen Information:
   • Check for allergen information, especially if you have known sensitivities. Ensure the supplement is free from common allergens like gluten, soy, and dairy, unless intentionally included for specific purposes.
6. Dosage and Potency:
   • Evaluate the dosage and potency of the supplement. Ensure it provides the recommended daily amount without excessive overdosing.
7. Scientific Evidence:
   • Look for supplements backed by scientific research. Products supported by well-conducted studies are more likely to be effective.
8. Brand Reputation:
   • Choose supplements from reputable brands with a history of producing high-quality products. Read reviews and testimonials from other users to gauge their experiences.
9. Formulation Purpose:
   • Select supplements based on your specific health needs. Whether you’re looking for immune support, energy enhancement, or general well-being, choose products formulated for those purposes.
10. Sustainability and Ethics:
    • Consider the company’s commitment to sustainability and ethical sourcing of ingredients. This is important for both environmental and ethical reasons.
11. Expiration Date:
    • Always check the expiration date to ensure the potency of the supplement. Using expired products may result in reduced efficacy.

Remember, it’s advisable to consult with a healthcare professional before introducing any new supplements, especially if you have underlying health conditions or are taking medication. They can provide personalized advice based on your individual health needs.
