Horse Chestnut Supplement Buying Guide 

It is always good to research a bit before buying any dietary supplement. We have designed this buying guide to help you pick the best chestnut supplement for your horse. Here are a few recommendations.

Dosage Recommendation 

Generally, the recommended Horse chestnut dosage is 400-600mg per day, usually, taken in two equal doses a day. Split doses are often recommended for best results because the active components in horse chestnuts take time to absorb completely. These supplements are available in capsule form, and you can take them with or without food.

The finest quality horse chestnut product will clearly mention the standardized amount of aescin present in each tablet. Typically, a chestnut extract standardized to 20% aescin is available in the market. The dosages for aescin extract should be around 100-150mg. So, if a supplement is available in 500mg of horse chestnut containing 20% aescin, this means it offers an aescin dosage of 100mg.

Safety And Side Effects 

Horse chestnut extract can cause several side effects, including nausea, itching, gastrointestinal problems, headache, and muscle aches.

To achieve the safe use of horse chestnut, make sure to ask your physician before you consider using the supplement to treat CVI or any other health condition.

If you have kidney disease or other bleeding disorders, you should avoid taking horse chestnuts. Never combine horse chestnut with Coumadin (warfarin), aspirin, Plavix (clopidogrel), and other antiplatelet (blood-thinning) or anticoagulant drugs unless your doctor prescribed. Because it may increase the side effects of these medications.

Be careful while using these supplements as they are not tested for safety, and therefore, are considered an unregulated dietary product. Also, there is a possibility that the ingredients of some products may differ from what is mentioned on the product label. 

Note: The safety of horse chestnut supplements in nursing mothers, pregnant women, children, and those with other medical conditions or taking medications hasn’t been established.

Arbutin speeds up the healing of varicose veins, while aescin prevents the blood from pooling in veins.

The blood vessels become dilated due to these body postures and cannot properly return to their standard size. In the end, the veins become stretched out.

Additionally, these supplements can be used for many other health conditions, including hemorrhoids, itchy skin, swelling in general, and pain associated with bruises.

What are some other benefits of chestnut supplements?

Antioxidant — A horse chestnut containing antioxidants properties, including flavonoids, can keep you healthy by fighting damage done by free radicals.
