1 What is it?
Pine bark extract is a supplement taken from the bark of a Mediterranean tree: the maritime, or cluster, pine. It may be used for the antioxidant properties of its main active ingredient, procyanidin which contains polyphenols.
2 How does pine bark extract help as an antioxidant?
The antioxidant effect is thought to support the body’s ability to recycle nutrients and maintain vitamin C and E level (also antioxidants). This may help those with chronic venous insufficiency (whereby the veins are not able to send blood back to the heart efficiently), at risk of retinopathy and support athletic performance (See fact 4 below).
There is some evidence suggesting the extract may support blood sugar balance through a reduction in oxidative stress. Additionally, pine bark extract may inhibit the production of nitric oxide and, while nitric oxide can be helpful, too much of it may cause harm.
Studies of humans are limited into the benefits of this product, and some findings are controversial in that the results have been mixed.
3 Where can I find it?
Pine bark extract may be found under different names, however the main one is pycnogenol. Unlike many compounds I discuss in consultations and blogs, it can only be found in supplements, and not food. It may be found in supplements combined with nutrients such as vitamin C.
If you wish to try the supplement, and you are not working with me, please ensure that you choose a reputable brand and if you have any queries regarding dosage contact the manufacturer or appropriately trained professional. See below for cautions, and my approach with clients.
4 What cautions should I take?
If you are taking any medication or other supplements, or have any health concerns, please ensure you seek advice from an appropriately trained professional before taking this supplement. To avoid any confusion, I have decided not to list any specific medications, supplements or health concerns that should be considered here. Bark pine extract may have immune stimulating effects, anti-platelet activity and hypoglycemic effects, which need to be borne in mind by anybody considering its use.
According to The Natural Medicines Database, common adverse effects may include gastrointestinal complaints, dizziness and vertigo. The effects may vary depending on dosage and the individual using the supplement.
5 Alible Nutrition’s position on supplements
As a nutritional therapist I recognise that supplements have their place in supporting individual’s health. As I am not a trained herbalist, I cannot routinely suggest herbal supplements to my clients. Some herbs are restricted by law meaning that they are officially recognised as traditional herbal medicines and can only be recommended or sold by those registered as medicinal herbalists.
Thankfully, despite not being a food product per se, pine bark extract is classified as a food supplement. It is therefore within my remit to recommend this product to clients if I believe it is beneficial and appropriate for the individual. Furthermore, I ensure there is scientific evidence to support any recommendations that I make.
