Seasonal allergies can be a bothersome issue for many, leading to symptoms such as sneezing, itchy eyes, and nasal congestion. As a cardiologist, I understand the importance of holistic health, which includes managing such allergies without compromising heart health. Here’s a review of some of the top supplements that can help alleviate seasonal allergy symptoms safely and effectively. At the end of the article, I have my seasonal allergy protocol for you.
1. Quercetin
Quercetin is a naturally occurring flavonoid found in many fruits and vegetables. It’s known for its antioxidant properties and ability to stabilize mast cells, which reduces the release of histamine—the chemical responsible for most allergy symptoms. For heart patients, quercetin also offers the benefit of promoting cardiovascular health by improving blood vessel function.
2. Vitamin C
A powerful antioxidant, vitamin C boosts the immune system and can help reduce the severity of allergy symptoms. It supports the function of various immune cells and has anti-inflammatory properties. This vitamin also plays a crucial role in cardiovascular health by aiding in the prevention of endothelial dysfunction, a common condition in heart patients that can lead to severe complications.
3. N-acetyl Cysteine (NAC)
N-acetyl cysteine, or NAC, is a supplement form of cysteine. Consumed as a supplement, NAC acts as a powerful antioxidant and expectorant, helping to thin out mucus and making it easier to clear from the airways. It is particularly beneficial for those with respiratory conditions exacerbated by allergies. NAC also has cardiovascular benefits as it helps to reduce oxidative stress and improve endothelial function, which are vital for maintaining heart health.
4. Bromelain
Bromelain is an enzyme found in pineapple juice and the pineapple stem. It is effective in reducing nasal swelling and thinning mucus, which can help relieve respiratory symptoms associated with allergies. Additionally, bromelain has been shown to have cardiovascular benefits by preventing blood platelets from sticking together and reducing inflammation, which is a risk factor for heart attacks.
5. Stinging Nettle
Stinging nettle is a perennial flowering plant that has been used medicinally since ancient times. It’s believed to have natural antihistamine properties, which can help manage the symptoms of allergic rhinitis. Stinging nettle is also beneficial for heart health; it acts as a diuretic, helping to lower blood pressure and support circulatory health.
6. Diamine Oxidase
Diamine oxidase (DAO) is an enzyme that helps degrade histamine in the body, thus potentially reducing allergy symptoms. A notable natural source of this enzyme is bison liver and heart. These organs not only supply DAO but also provide a rich array of nutrients that support overall health, including the cardiovascular system.
7. Probiotics
Probiotics are beneficial for seasonal allergies as they help balance the gut microbiome, which is closely linked to the immune system. A healthy gut can lead to improved immune regulation and a reduced inflammatory response to allergens. Probiotics may also help boost the production of regulatory T-cells, which can help decrease allergic responses.
8. Omega-3 Fatty Acids
Omega-3 fatty acids, predominantly found in seafood like salmon, mackerel, and sardines, are crucial for their anti-inflammatory properties. They can significantly reduce the production of inflammatory cytokines and eicosanoids, which are prevalent during allergic responses. Regular consumption of omega-3 rich foods can help mitigate the intensity of allergy symptoms and promote overall cardiovascular health.
Protocol:
- Kickstart My Heart (loaded with vitamins, minerals, proteins and fat…plus diamine oxidase)
- Wild Salmon Roe (all the vitamins, minerals, proteins, and fats, including omega 3 fatty acids
- Heart Helpers probiotic
- Hist-PRO: Contains all items 1-5 above. 2 caps up to 3x per day.
The protocol can be used acutely for symptoms, but works best when starting a week or two before “allergy season”.
