PRODUCT FAQ

 

SKU: SH-HD Categories: , Tags: ,

Seeking Health DAO Enzyme is formulated to support individuals with histamine intolerance or sensitivities. Each capsule contains DAO, an enzyme essential for breaking down histamine in the body, particularly in the small intestine, colon, and other organs. This enzyme plays a critical role in metabolizing excess histamine, whether ingested through diet or produced internally. Additionally, the supplement includes Vitamin C, a crucial co-factor for DAO’s production and function, increasing its effectiveness.

Key Benefits:

  • May help support digestion of food-derived histamine in the digestive tract
  • May help support normal inflammatory responses in the digestive tract
  • Contains Vitamin C, which assists in normalizing DAO levels and aids in histamine breakdown.
  • May provide relief from symptoms like migraine headaches, nasal congestion, and skin issues associated with high histamine levels.

This product may benefit individuals experiencing symptoms of histamine intolerance, including recurrent headaches, gastrointestinal problems, sneezing, and skin irritation. It is particularly useful for those who have identified dietary histamine as a trigger for these symptoms.

Suggested Use

Take 1 capsule, as needed, just prior to consuming high histamine foods or drinks. Or, take away from food if wanting to support healthy histamine levels in the digestive tract. Use as directed by your healthcare professional.

Seeking Health Australia

Practitioner-grade supplements designed for clarity, tolerance, and individual needs Seeking Health is a practitioner-focused supplement brand developed to support individual nutritional needs with a strong emphasis on formulation clarity and tolerance. Founded by Dr Ben Lynch, Seeking Health is best known for its work in areas such as methylation, histamine balance, gut health, and immune support. The brand offers a broad range of supplements — from everyday nutritional foundations to more targeted products for people who don’t respond well to standard formulations. At Fairfield, we stock a wide selection of Seeking Health products used by practitioners and individuals who want more control and predictability in how supplements affect them.

What makes Seeking Health different

Designed for people who don’t tolerate “standard” supplements well

Many supplements are formulated with the assumption that everyone responds the same way. In practice, this often isn’t true. Seeking Health products are commonly chosen by people who:
  • feel overstimulated by certain vitamins (especially B vitamins)
  • react poorly to additives or excipients
  • need more flexibility around dose and form
  • want supplements that can be adjusted rather than “one-size-fits-all”
This approach makes the range particularly useful for people who’ve struggled with multivitamins or complex blends in the past.

How to think about using Seeking Health products

The range naturally divides neatly into the categories we like to use:
  • foundational products that suit many people and can be used long-term
  • targeted products designed for specific patterns, sensitivities, or short-term support
This makes it easier to start simply, observe how you respond, and only layer additional support if it’s genuinely needed.

🟢 Foundational Seeking Health products

Suitable for many people, including longer-term use Foundational products are typically used to support:
  • baseline nutrient intake
  • nervous system and muscle function
  • digestion and fat absorption
  • general immune and metabolic health
These are often the first products people introduce. Common foundational options include:
  • Optimal Multivitamin – comprehensive daily nutrient support with careful balance
  • Multivitamin One – simplified daily multivitamin for those wanting fewer ingredients
  • Optimal Magnesium – well-tolerated magnesium support for muscles and nervous system
  • Vitamin C Plus – foundational antioxidant and immune support
  • Vitamin D3 – baseline vitamin D support when sun exposure is limited
  • Vitamin D3 + K2 – combined fat-soluble vitamin support for bone and cardiovascular health
  • Fish Oil – omega-3 fatty acids for general inflammatory balance
  • Digestive Enzymes – broad-spectrum enzyme support to assist digestion
  • Optimal Man – foundational nutrient support formulated for male health needs
These products suit most people. Those with very sensitive systems may still benefit from lower starting doses or slower introduction.

🟡 Targeted Seeking Health products

Best used for specific sensitivities or clearer needs A large part of the Seeking Health range is designed for more specific situations, particularly where standard supplements haven’t worked well. Targeted products are commonly used to support areas such as:
  • histamine sensitivity or intolerance
  • methylation-related nutrient needs
  • immune regulation
  • gut-related reactivity
  • stress and neurotransmitter balance
These products are usually:
  • added on top of foundations
  • used with clearer intent
  • reassessed rather than taken indefinitely
If you’re unsure whether a targeted product is appropriate, it’s generally better to begin with foundational support first.

A practical note on individual response

Seeking Health products are intentionally flexible — which means responses can vary. Some people notice benefits quickly. Others may need to:
  • adjust dose
  • simplify what they’re taking
  • allow more time between introducing products
This doesn’t mean a product is “wrong”. It usually means your body needs a more gradual or selective approach. Doing less, more carefully, is often the fastest way forward.
