QUICK ANSWER
Only a little, on average. Pooled trials found pine bark extract lowered LDL cholesterol by about 0.1 to 0.2 mmol/L and systolic blood pressure by about 2 to 3 mmHg. A Cochrane review called the evidence inconclusive. To see if it works for you, test LDL and ApoB before you start and 12 weeks later.
Your cholesterol came back a bit high, or your blood pressure was borderline at the pharmacy. Someone online swears by 100mg of Pycnogenol a day. So you bought a tub. Is it doing anything?
The honest answer is that the average effect is small and the studies disagree. Your own blood is the only way to know what it did for you. If you already hold a result, start with what your LDL number means.

As of October 2026. Pycnogenol is a busy topic on supplement forums this month. The newest pooled analysis, published in BMC Complementary Medicine and Therapies in February 2025, covered 27 trials.
1. What is Pycnogenol?
It is a branded extract of French maritime pine bark.
The bark is rich in plant compounds called procyanidins, a type of flavonoid. These are the same family of compounds found in cocoa, grapes and tea. Pycnogenol is the most studied pine bark product, so most trials use it.
People take it hoping to lower LDL cholesterol, the type that can build up in artery walls, and to ease blood pressure. It is sold as a food supplement in the UK, not as a medicine.
2. Does Pycnogenol lower cholesterol?
A little, in some analyses. Not at all, in others.
- A 2014 analysis of 7 trials found no clear effect on LDL, HDL, total cholesterol or triglycerides.
- A 2019 analysis of 24 trials found LDL fell by about 0.18 mmol/L and HDL rose slightly.
- A 2025 analysis of 27 trials found LDL fell by about 0.13 mmol/L, with no change in total cholesterol or triglycerides.
Here is what that looks like. If your LDL is 3.8 mmol/L, a 0.15 fall takes it to about 3.65. That is around 4%. Plant sterols, by comparison, average 7.5 to 12% in our plant sterols guide.
Blood pressure moved a bit more consistently. Both newer analyses found systolic pressure, the top number, fell by about 2 to 3 mmHg. HbA1c, a three-month average of your blood sugar, dipped slightly too.
The trials were mostly small and short. Cochrane, which reviews evidence for health decisions, looked at 27 of them in 2020:
“Small sample sizes, limited numbers of RCTs per condition, variation in outcome measures, and poor reporting of the included RCTs mean no definitive conclusions regarding the efficacy or safety of pine bark extract supplements are possible.”
So the trial average tells you what might happen. It cannot tell you what happened in your arteries. Our cholesterol blood test guide explains every line of a lipid report.
3. Who should check with a GP first?
Anyone already on heart or blood sugar medicine.
That means statins, blood pressure tablets, blood thinners and diabetes medicine. Ask your GP or pharmacist before you add Pycnogenol to any of them. The same goes if you are pregnant or breastfeeding.
Do not use it in place of anything you were prescribed. A 0.15 mmol/L drop is far smaller than a statin gives, and no trial has shown that pine bark means fewer heart attacks or strokes.
4. How do you tell if Pycnogenol is working for you?
Test before you start, then again at 12 weeks.
Twelve weeks gives LDL time to settle and lets HbA1c cover the full period. These are the markers worth tracking:
- LDL cholesterol is the number the trials measured most.
- ApoB counts the particles that carry cholesterol into artery walls.
- Non-HDL cholesterol adds up every harmful type in one figure.
- hs-CRP is a sensitive marker of low-level inflammation.
- HbA1c shows your average blood sugar over about three months.
Blood pressure is not a blood test. Check it at home or at a pharmacy on the same days, at the same time of day.
Change one thing at a time. If you also start citrus bergamot or a new diet, you will not know which one moved your numbers. LDL also wobbles a few percent between tests on its own. With an average effect this small, look for a clear drop, not a tiny one.
The Helvy Advanced Heart Health panel (£159) reports LDL, non-HDL, ApoB, hs-CRP and HbA1c in one finger-prick kit, with Lp(a) alongside. A blood test measures. It does not diagnose. Anything outside range is one to take to your GP.
Frequently asked questions
Does Pycnogenol lower LDL cholesterol?
Pooled trials found an average fall of about 0.1 to 0.2 mmol/L, though one earlier analysis found no effect. Your own result may differ, so test before and after.
Does pine bark extract lower blood pressure?
Two analyses found systolic pressure fell by about 2 to 3 mmHg on average. Cochrane said the blood pressure evidence it found in people with heart disease was very low certainty.
When should I retest after starting Pycnogenol?
At around 12 weeks. That gives LDL time to settle and lets HbA1c reflect the whole period.
Which Helvy panel checks LDL and ApoB?
Advanced Heart Health (£159) reports LDL, HDL, triglycerides, non-HDL and ApoB, plus Lp(a), hs-CRP and HbA1c.
