Astaxanthin

Astaxanthin

Astaxanthin stands out as one of nature's most powerful antioxidants. This remarkable compound gives salmon and flamingos their distinctive pink colour and offers significant health benefits for humans. Scientists have discovered that astaxanthin provides stronger antioxidant protection than other well-known nutrients. This article explores the advantages, proper usage, and important considerations for taking astaxanthin supplements, helping readers make informed decisions about their health.

What is Astaxanthin?

Astaxanthin is a red-orange carotenoid pigment that belongs to the xanthophyll family. This naturally occurring compound consists of carbon, hydrogen & oxygen atoms, with a molecular formula of C40H52O4 and a melting point of 224°C. Its unique molecular structure allows it to anchor across cell membranes, providing exceptional protection against oxidative damage.

The US Food & Drug Administration (FDA) has recognised astaxanthin as safe for consumption, approving it as a dietary supplement in 1999. This powerful compound occurs naturally in various marine sources:

• Microalgae (particularly Haematococcus pluvialis)
• Marine creatures (shrimp, krill, salmon)
• Freshwater organisms (trout)
• Certain types of yeast
• Various forms of plankton

Natural astaxanthin demonstrates superior biological activity compared to its synthetic counterpart. The natural form, particularly from Haematococcus pluvialis, shows more than 50 times stronger singlet oxygen quenching capability than synthetic versions. This remarkable difference explains why natural astaxanthin commands a higher market price. 

Astaxanthin Tablet Uses

The therapeutic applications of astaxanthin tablets extend across multiple health domains, making it a versatile supplement for various medical conditions. Research has shown that this powerful antioxidant protects against free radicals in the human body, supporting overall health and wellness.

• Benefits for Immune System Function: It activates white blood cells (WBCs) and natural killer cells, enhancing the body's natural defense mechanisms. 
• Support Cardiovascular Health: The supplement helps to:
  • Reduce LDL (bad) cholesterol levels
  • Increase HDL (good) cholesterol
  • Lower high blood pressure
  • Protect heart muscle from oxygen deficiency
• Brain Health Support: Studies indicate that astaxanthin can cross the blood-brain barrier, offering protection against neurodegenerative conditions and managing symptoms associated with Alzheimer's and Parkinson's disease. However, more research is ongoing in this area.
• Reduce the Growth of H. pylori Bacteria: This bacterium causes peptic ulcers. Astaxanthin can significantly reduce the growth of this bacteria in the digestive tract.
• Diabetes Management: The supplement shows potential in protecting against kidney damage, though regular monitoring under medical supervision is essential.
• Additional Health Benefits: The compound demonstrates significant anti-inflammatory properties, potentially helping with conditions such as rheumatoid arthritis and celiac disease. It accumulates in the skin's epidermis and dermis layers, providing natural protection against UV damage and supporting skin health.

How to Use Astaxanthin Tablet

Proper administration of astaxanthin tablets requires attention to timing and method of consumption for optimal absorption. The supplement comes in several convenient forms to suit different preferences, including capsules, tablets, drops, and powder.

• Timing and Absorption: Proper administration of astaxanthin tablets requires attention to timing and method of consumption for optimal absorption. While the supplement can be taken at any time, establishing a consistent schedule helps maintain regular usage.
• Administration Guidelines: The optimal absorption occurs when taken with food items rich in healthy fats, such as:
  • Olive oil
  • Avocados
  • Nuts
  • Fish
• This approach enhances absorption 2 to 4 times compared to taking it on an empty stomach.

Side Effects of Astaxanthin Tablet

While astaxanthin tablets demonstrate a strong safety profile, understanding potential side effects helps users make informed decisions about supplementation. The Food & Drug Administration (FDA) has classified astaxanthin as safe (GRAS) when consumed within recommended dosages.

However, some people may experience common side effects, particularly at higher astaxanthin doses:

• Digestive system discomfort
• Increased frequency of bowel movements
• Red-coloured stools
• Mild stomach pain
• Temporary changes in digestion

Severe Reactions: Though rare, severe allergic reactions can occur. Users should immediately seek medical help if they experience difficulty breathing, itching, or rash development. Research indicates that even at high doses, astaxanthin shows minimal risk of severe side effects in most healthy adults.

Precautions

• Medical Conditions: Individuals with concomitant health conditions should exercise particular caution when considering astaxanthin supplementation:
  • Bleeding disorders
  • Diabetes
  • Autoimmune disorders
  • Hypertension
  • Low blood calcium levels
  • Parathyroid disorders
  • Asthma
• Older Adults: Adults over 65 years should approach astaxanthin supplementation with additional care, as this age group typically experiences a higher likelihood of medication side effects. 
• Kids: Children require special consideration, as most astaxanthin products target adult populations and lack specific dosing guidelines for younger individuals.
• Pregnancy and Lactation: Pregnant and breastfeeding individuals should avoid astaxanthin supplementation due to limited research on its effects during these periods. 

How Astaxanthin Tablet works

The molecular structure of astaxanthin enables it to function as a powerful cellular protector in the human body. This unique compound positions itself across cell membranes, creating a protective shield that spans the inner and outer layers of cells.

Primary Mechanisms of Action:

• Neutralises harmful free radicals through electron donation
• Forms stable compounds with reactive oxygen species
• Protects cell membrane integrity
• Enhances mitochondrial function
• Improves blood flow properties

Can I Take Astaxanthin with Other Medicines?

The following medications require special attention when taken with astaxanthin:

• Blood Thinner Considerations: Research indicates that combining astaxanthin with blood-thinning medications may increase the risk of bleeding and bruising. Doctors may need to monitor patients closely and adjust medication dosages accordingly.
• Cholesterol Medication: Individuals taking cholesterol-lowering medications should exercise particular caution. Astaxanthin can affect cholesterol levels, potentially creating additive effects when combined with statins or omega-3 fatty acids.
• Immune System Medications: Careful monitoring becomes essential for those taking immune support medications like adalimumab. Astaxanthin's effects on the immune system may interact with the following medications, requiring professional oversight:
  • Blood pressure medications
  • Hormone-affecting drugs

Dosing Information

The recommended daily intake of astaxanthin typically falls within these parameters:

• Basic Supplementation: 4-6 mg daily
• Therapeutic Purposes: 8-12 mg daily
• Maximum Studied Dose: 40 mg daily
• Maintenance Dose: 4 mg daily

Duration and Timing: Studies indicate safe usage patterns across different timeframes:

• Short-term Use: 4-40 mg daily for up to 12 weeks
• Long-term Use: 4 mg daily with other supplements for up to 12 months
