Dietary supplements of omega-3 (n-3) fatty acids reduce blood pressure in hypertensive patients, but it seems this effect does not appear in healthy individuals. In simple words, Hemp seed oil will not cause low blood pressure and faintness in people with normal values, but it will reduce it in hypertensive (high blood pressure) patients. This lowers the risk of cardiovascular diseases such as stroke and heart attack.
According to the research published in the Journal of Hypertension (official journal of European Society of Hypertension), omega-3 fatty acids are recommended to be used as an adjunct therapy combined with diuretics and beta blockers in order to achieve better blood pressure control .
Heart Disease & Hemp Seed Oil
A 2007 study found that hemp seed oil was able to prevent blood clots from forming. This could be a potential medicine for preventing clot-induced strokes and heart. Researcher in another study concluded that hemp seed oil may provide significant protection from strokes. Recent analysis conducted by the American Chemical Society found that intake of omega-3 fatty acids may prevent coronary heart disease prevention.
When it comes to hemp seed oil specifically, researchers have discovered that it is the plant sterols – special compounds found in plants known to lower cholesterol – that potentially prevent heart problems. Hemp seed oil also contains tocopherols, which reduce the risk of degenerative heart diseases, among a variety of other conditions.
Inflammation is a good thing- as long as it’s under control. That’s how the body fights off bacteria and other microorganisms and how it heals itself. But sometimes inflammation gets out of control and establishes as a permanent process, damaging the body functions and causing severe health issues in the long run. Medical research in the past decade revealed it’s the missing link between obesity and diabetes.
A study published in 2013 revealed that omega-3 fatty acids lower biomarkers of body inflammation and metabolic syndrome . Although this finding may seem not so spectacular to laymen, what it tells us is that hemp seed oil can help you prevent diabetes, put the insulin resistance under control or interrupt the obesity- metabolic syndrome- diabetes cascade in time, before serious health complications occur.
Most clinical studies looking at omega-3 supplements for arthritis have focused on rheumatoid arthritis, an autoimmune disease that causes inflammation in the joints. Several small-scale studies found that supplementation reduced symptoms of rheumatoid arthritis, including joint pain and stiffness. One study suggests that people with rheumatoid arthritis who take fish oil may be able to lower their dose of painkillers (NSAIDs).
An analysis of 17 randomized, controlled clinical trials looked at the pain-relieving effects of omega-3 fatty acid supplements in people with rheumatoid arthritis or joint pain caused by inflammatory bowel disease (IBS) and painful menstruation (dysmenorrhea). The results suggest that omega-3 fatty acids, along with conventional therapies, such as NSAIDs, may help relieve joint pain associated with these conditions.
Lowering Blood Cholesterol
Omega 3 is well known for it’s effect on blood pressure, regularly given to patients by doctors on prescription. Increasing the amount of hemp seed oil in your diet may help cholesterol-lowering medications called statins work more effectively. These medications include:
- Atorvastatin (Liptor)
- Lovastatin (Mevacor)
- Simvastatin (Zocor)
Management of hypertriglyceridemia
Hypertriglyceridemia, one of the most common metabolic disorders, is a condition of elevated triglycerides in the blood. It is essential to understand that omega-3 fatty acids have their place in therapy of different health conditions. These supplements are not always the best choice. For example, in cases of severe hypertriglyceridemia, it’s essential to put it under control as fast as possible, before acute pancreatitis develops (often deadly inflammation of the pancreas).
On the other hand, in patients with moderate elevation of triglycerides, omega-3 fatty acids (Hemp Seed Oil) can be used as an adjuvant or single therapy option . Unlike statins, omega-3 FA does not have side or adverse effects, and no drug interactions have been recorded so far. Also, they do not affect liver function (unlike statins which show the hepatotoxic effect in some patients). Why is this important? In some cases, introducing another drug into the therapy of a patient who already regularly takes a few medications can trigger side effects or interact with some of the drugs, changing their “behavior” in the body (a phenomenon with the sometimes fatal outcome).
Hemp seed oil is rich in GLA (gamma linolenic acid), a building block from some prostaglandins. Prostaglandins play an important role in the body’s function, helping smooth muscles contract, controlling body temperature and inflammation, and other bodily functions. This research suggests that supplementing with GLA is important for optimal hormone health, and may be why so many women with PMS have been helped by hemp seed oil. One study of women with PMS required the women take one gram of essential fatty acids (including 210 mg of GLA) daily. This resulted in a significant reduction in their PMS symptoms. Hemp seed oil’s high levels of GLA indicate that it may also help reduce menopause symptoms.
The past two decades brought omega-3 fatty acids into the focus of scientific research. All world known medical journals, published on monthly basis research results that push further the boundaries of our omega-3 fatty acids understanding. Two or three decades ago, it was unimaginable to hear a doctor say “use more omega-3 fatty acids in your diet to regulate your blood lipids level”. Today, it would be wrong not to try those before introducing drugs into the therapy. Keep in mind that omega-3 fatty acids are not the magical solution for every health problem- sometimes you will need drugs (especially in situations when it’s crucial to achieve therapeutic effect as fast as possible). Hemp Seed Oil is a natural source of omega-3 fatty acids and a great alternative to processed fats we consume so much nowadays.
Why is hemp seed oil so healthy?

The Perfect Balance
Hemp Seed Oil is nature’s most perfectly balanced plant oil because it has a very healthy 3:1 ratio of Omega 6 to Omega 3. 
In the modern diet, the ratio of Omega 6 to 3 can be as distorted as 20:1 (trans fats, and processed vegetable fats being to blame for this). Views vary, but most agree that the ratio should be between 5:1 and 3:1. 
Hemp seed oil is known to contain up to 5% of pure GLA, a much higher concentration than any other plant . GLA has been shown to reduce inflammation in the body.  
Understanding Fats and Essential Fatty Acids
A modern obsession has developed with fats. “Low-fat” has become part of the modern culture. But there are many misunderstandings about the different types of fats, their impact upon health and their role in therapeutic nutrition.
Essential Fatty Acids are an essential for health and vitality . They cannot be made by your body, so they need to be included in your diet . They are often referred to as the “Good Fats”. This special group of fats that deserve most attention when it comes to health and nutrition.
Essential fatty acids fall into two groups omega 3 and 6 (parent essential fatty acids), and your body uses them to make derivatives of these. 
Processed / synthetic fats are generally referred to as:
These should be completely eliminated from your diet if you want to achieve optimum health and vitality . Even those saying for example “virtually free from trans fats” should be left out of your shopping basket, checking labels is essential.
Hydrogenated fats have absolutely no nutritional benefit, and are in fact harmful . Synthetic fats form new molecular structures unacceptable to the human physiology . Evidence continues to grow about the health risks (although researchers began to document the risks back in the 70s).
The soaring rates of health conditions such as heart disease go hand in hand with the dramatic rise in processed vegetable oils and are nothing to do with the consumption of natural fats such as butter. We don’t have to go back very far to find evidence of diets extremely high in saturated fats, and yet a low incidence of heart disease. Even today, we can find groups of people with high fat diets, and still a low incidence of heart disease, obesity and other conditions often associated with saturated fats . This is called the “French Paradox”.
So let’s look at the natural fats
These fall into three main headings (sub headings will be looked at below):
Saturated fats are solid in form, when stored at room temperature. Subject to intense negative publicity, probably even more so than trans fats, saturated fats are much misunderstood. Lard and Butter for example are natural saturated fats, and in moderation are perfectly healthy .
These can be found in some healthy oils, and foods such as olives, almonds, pecans and avocados. Olive Oil is a key part of the Mediterranean diet known for its health benefits .
They are found in various vegetable oils, corn, sunflower, safflower, sesame and soy.
Most polyunsaturated fats are weighted far too heavily towards omega 6. While some are better than others, some should be avoided completely, especially when refined and processed .
Essential Fatty Acids
ALA – (alpha-linolenic acid) is a “short chain” fatty acid found in plant sources, such as hemp seed oil, flaxseed oil and walnuts. Unique to plants, even those who eat a lot of fish would be well advised to ensure adequate intake  .
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are “long chain” fatty acids found in fish, the best sources being salmon, sardines, mackerel, herring, halibut and sea bass .
The science is complex, however, in short, if you’re consuming good quantities of ALA (short chain), this converts to EPA and DHA in the body .
Omega-6 – Good and Bad!
Also known as Linoleic Acid, and is mainly found in plant oils. But also beef, chicken (especially non grass fed), grains and eggs . Intake for many people is too high, as frying oils are mostly the “bad forms” of omega 6. However, “good omega 6”, such as GLA, is needed in the right quantities for health .
Eliminating processed foods, eating oily fish regularly, and consuming good oils such as Hemp Seed Oil with leafy greens  easily brings the balance of omega fatty acids in the body back into balance .
