Winter Blues: Vitamin D & Sunlight Needed to Make Serotonin

Without enough vitamin D, we are unable to synthesize serotonin. Serotonin regulates our mood, whether we have positive or negative thoughts, inner rest and confidence, appetite, sleep, cognitive functions like memory and learning! It’s a neurotransmitter that’s vital for many brain functions including regulating dopamine levels, which plays a role in reward-mediated behavior. Did you know that we need Vitamin D to make serotonin? Vitamin D is needed to support the conversion of tryptophan into serotonin. So being outdoors in the...

Serum DAO May Help Diagnose Histamine Intolerance

Histamine intolerance may develop when the body doesn’t have the capacity to fully metabolize and degrade histamine. Whether it’s from the histamines found in or triggered by food or medications, or from other environmental factors, this imbalance overwhelms the body. The main enzyme that metabolizes ingested histamine is produced by the body, though often not in adequate amounts, is diamine oxidase. It is referred to as DAO. In a 3 1/2 year study*, researchers determined that DAO (diamine oxidase) activity in serum along with a...

Study: Lower Serum DAO in Patients with Histamine Intolerance

The enzyme DAO (Diamine Oxidase) breaks down histamine in the gut. So what happens when you don’t have enough active DAO, or too high level of histamines? Often this leads to Histamine Intolerance, also referred to as HIT. A common symptom is gastric hypersecretion manifested with GI discomfort when eating. Many of my clients with histamine intolerance report relief when taking a DAO enzyme supplement with meals. This study concluded similarly, that people who exhibited a histamine intolerance, the majority of whom had lower serum DAO...

Biochemistry: Why DAO Can Help Histamine Intolerance

Biochemistry: Why DAO Can Help Histamine Intolerance

  Look at the histamine pathways and you’ll see why the supplement DAO (diamine-oxidase) helps many people with their symptoms of histamine intolerance! The image shows the biochemistry of how histamine gets degraded in the body. The breakdown of histamine is through two pathways: via the enzyme DAO in the gut, or via the enzyme HNMT in the rest of the body. Some people just don’t make enough of their own DAO enzyme. This could be due to a genetic SNP that they have. Or, it could be that their requirement for DAO may be very...
