What is sea buckthorn oil?

Sea buckthorn oil is a type of oil known for its high omega-7 content. It is typically used for improving heart health and lowering inflammation. This article is about the main benefits of sea buckthorn oil, its potential side effects, the best time to take it, and more.

What does sea buckthorn oil do for the body?

Sea buckthorn oil may increase HDL and lower LDL cholesterol levels, at least in unhealthy individuals.

It can also have anti-inflammatory properties and may improve the hydration of dry skin and mucous membranes.

Possible benefits

The benefits mentioned below are dose-dependent. Generally, the higher the dose, the more pronounced the effects are. However, they do reach a plateau at a certain point. We will discuss the best dosing protocol later in this article.

Minor benefits

Hydration of dry eyes – 2 grams of sea buckthorn oil is able to reduce symptoms of dry eyes, particularly the reddening and the perceived dryness.
Improved cholesterol and triglyceride levels – People with poor cholesterol profile may notice an increase in HDL and a decrease in LDL. Sea buckthorn may also help lower triglyceride levels if they are unnaturally high. However, these benefits do not seem to apply to healthy individuals.

Possible side effects

These side effects are dose-dependent. The risk for them increases (often linearly but sometimes exponentially) as you increase the dose. Some of the side effects only apply to very high doses.

Nausea
Diarrhea
Oxidation – Omega 7 from sea buckthorn oil or other sources is prone to oxidation and can become a pro-oxidant that can easily cause more harm than good in the body. This is why you need to choose the brand you get omega 7 supplements from carefully and store the supplement well.
Toxicity – While acute toxicity is extremely rare, taking high amounts of sea buckthorn oil could lead to chronic toxicity and cause some health problems. To prevent chronic toxicity, it is best to stay below 5 grams a day unless you have a great reason to take more.
Contamination – Contaminated supplements are uncommon in the USA and other well-regulated countries. However, if you wish to buy products from China, India, or other countries without strict regulations, beware that the supplements may be contaminated. Either way, you need to choose the brand you order from wisely. It is highly recommended to check the certificates or read through some reviews for the specific product before you buy it. The FDA (Food and Drug Administration) has the power to regulate dietary supplements but can only do so after they have been on the market for a while. That’s because supplement companies are not obligated to announce to the FDA when releasing a new product on the market. The FDA has to discover the product and test it for potential impurities, which can take a lot of time. During that time, the supplement can be sold on the market even if it’s impure. Also, supplement companies can change their manufacturers without announcing it to the FDA.

Who should not take sea buckthorn oil?

You should probably avoid taking the supplement if you:

experience a severe adverse reaction after taking the fatty acid
are on a tight supplement budget (since there are more cost-effective supplements on the market for most people)

Who will benefit the most?

You should consider taking the supplement if you:

are on a very low-fat diet
experience dry eyes

How much sea buckthorn oil should you take?

If you plan to take sea buckthorn oil as a supplement, 2 grams appears to be the best daily dose for most people. This amount should provide most of the benefits without meaningful side effects.

The upper safety limit for sea buckthorn is not well-established. To stay on the safe side, don’t take more than 5 grams daily unless you have a great reason to do so. Higher amounts may cause problems if you take the supplement for a prolonged period.

Best time to take sea buckthorn oil

Most bioactive compounds in sea buckthorn oil are fat-soluble so make sure to take it with food to absorb it well.

Whether you take the supplement in the morning or the evening doesn’t matter much.

Unless it feels too impractical, spread the daily dose into 2+ smaller doses throughout the day.

Where to buy sea buckthorn oil

Amazon is the best option for ordering sea buckthorn oil in most countries. They offer some very affordable products backed by many positive reviews. Also, you can choose from a wide range of brands without having to search through other markets on the internet.

Beware some brands display the dosage per serving instead of per pill or capsule. Therefore, you may accidentally buy something less potent than you intended. Do not fall for this marketing trick.

FAQ

You can take the fatty acid daily and do not need to cycle it. However, it is certainly not a problem if you don’t take it every day. Not taking the supplement every once in a while could lead to better absorption. That is yet to be proven or disproven.

All of these options are fine. The two most important things to consider are the price and dosing. Powders are almost always the cheapest form. However, you may need a highly accurate scale to dose them correctly (preferably 0.001g). You can get one for as little as $20 from Amazon. Dosing the powders also takes some time that can add up over months or years. The disadvantage of capsules is that they often contain bovine gelatin, which rarely comes from an ethical source.

Yes. Most fatty acids, including omega 7, absorb and digest well if you take them before falling asleep. The supplement should not impact sleep quality in any significant way.

This fatty acid can oxidize and become harmful if kept in bad conditions. Unfortunately, many omega 7 supplements are already heavily oxidized by the time you buy them, which is why choosing a high-quality brand is important.

Keep the supplement in a cold, dark, and dry place, and it should remain just as potent for many months.

While toxicity is rare, too much sea buckthorn oil can cause some health problems, often related to oxidation or causing an imbalance in fatty acids. It is best to stay below 5 grams a day to prevent these side effects.

In the long term, you need to take the supplement for about 2-4 weeks to begin noticing the benefits.

Yes, sea buckthorn oil is vegan-friendly. If you buy the supplement in a capsulated form, beware that the capsules often contain animal-based gelatin. Instead, find a brand that puts its products into cellulose capsules.

Most bioactive compounds in sea buckthorn oil are fat-soluble, so you need to take it with food to absorb it well.

Sea buckthorn oil should not break a fast unless you take a very high dose at once. If you practice time-restricted eating, take this fatty acid during your eating window to make sure it absorbs well and doesn’t break your fast.
