What Is Sacha Inchi Oil? The Plant-Based Omega-3 Worth Knowing About

If you’ve been anywhere near wellness social media recently, sacha inchi oil has probably crossed your path more than once. Search interest has spiked sharply this year, with a wave of enthusiasm coming from beauty and health circles, particularly in Asia Pacific. The claims being made online are bold, and quite a few of them are, frankly, not supported by the evidence.

What sacha inchi oil actually is, though, is genuinely interesting. It’s a plant-based source of omega-3, high in ALA, with an interesting nutritional profile, real research behind it, and a specific authorised health benefit that’s worth understanding properly. Here’s the full picture, without the hype.

What Is Sacha Inchi?

Sacha inchi (Plukenetia volubilis) is a perennial climbing plant native to the Peruvian Amazon, where its seeds have been consumed by indigenous communities for centuries. Sometimes called the Inca peanut, it produces small star-shaped pods containing seeds that are cold-pressed to make a pale yellow oil with a mildly nutty flavour.

What makes sacha inchi particularly interesting, nutritionally speaking, is its fatty acid profile. Around 80 to 90 per cent of its fat content is polyunsaturated fatty acids (PUFAs), with alpha-linolenic acid (ALA), a plant-based omega-3, making up roughly 47 to 51 per cent of the total. That makes it one of the most concentrated plant sources of ALA you can find.

What Are the Different Sources of Omega-3?

Not all omega-3 fatty acids are the same, and understanding the difference matters when you’re choosing a supplement. 

There are three main types:

ALA (alpha-linolenic acid) is a plant-based omega-3 found in flaxseed, chia seeds, walnuts, hemp seeds, and sacha inchi. It’s an essential fatty acid, meaning the body cannot produce it, and it must come from food or supplementation. ALA contributes to the maintenance of normal blood cholesterol levels (the beneficial effect is obtained with a daily intake of 2g of ALA), which is its authorised health claim under UK food supplement regulations.

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are long-chain omega-3s found primarily in oily fish such as salmon, mackerel, and sardines, as well as in algae-based supplements. These are the forms most associated with cardiovascular and cognitive health benefits in clinical research. Our bodies can convert some ALA to EPA and DHA, though this conversion is limited.

For anyone following a plant-based diet, or who simply doesn’t get on with fish oil supplements, ALA-rich sources such as sacha inchi are a genuinely worthwhile option for supporting omega-3 intake. They’re not a direct replacement for EPA and DHA, but as part of a balanced approach to essential fatty acid nutrition, they have real value.

What Does the Research Say About Sacha Inchi Oil?

The evidence base for sacha inchi has been growing over recent years, with several human trials now available. 

What the Research Shows: Cholesterol and Heart Health

This is the area with the strongest evidence. In a randomised study, healthy adults who consumed 10 to 15ml of sacha inchi oil daily over 16 weeks saw reductions in total cholesterol and LDL (low-density lipoprotein) cholesterol, with improvements in HDL (high-density lipoprotein) cholesterol too. A separate double-blind, placebo-controlled trial in adults with elevated blood pressure, cholesterol, and blood glucose found significant improvements in cardiovascular risk markers compared to a corn oil placebo. ALA contributes to the maintenance of normal blood cholesterol levels, and these findings are consistent with that.

Bioavailability: Does the ALA Actually Get Into the Body?

A fair question, and one the research answers clearly. A human study comparing sacha inchi oil to sunflower oil found that consuming sacha inchi oil significantly raised plasma levels of ALA. Levels of DHA also increased following sacha inchi oil intake, while sunflower oil produced no such changes. The omega-3 fatty acids in sacha inchi oil do become bioavailable after ingestion.

Vitamin E and Antioxidant Benefits

Sacha inchi oil naturally contains vitamin E, particularly gamma and delta-tocopherols, which are among the most potent forms of this nutrient. Vitamin E contributes to the protection of cells from oxidative stress, which is the everyday wear and tear caused by unstable molecules in the body. It’s a meaningful part of the nutritional picture, even if it is not the headline story.

What the Research Does Not Support

Social media is awash with bold claims about sacha inchi oil that include: weight loss, diabetes management, eye health, memory and fertility. Some posts have even drawn comparisons with GLP-1 weight-loss medications, which is quite a leap.

To be straightforward about it: none of these claims are supported by the available evidence for ALA-based omega-3s. Many of the benefits being promoted, where they do exist in the research, relate specifically to EPA and DHA rather than ALA. They are different fatty acids with different properties, and the distinction really matters.

At Metabolics, we won’t make claims we can’t support. We think that’s worth saying plainly, because plenty of brands don’t apply the same standard. If you’re reading something about sacha inchi online that sounds extraordinary, it’s worth asking where the evidence comes from.

Who Might Benefit from Sacha Inchi Oil?

Sacha inchi oil is worth considering if you:

• Follow a vegan or vegetarian diet and want a plant-based source of omega-3
• Dislike or cannot tolerate fish oil supplements
• Want to improve your omega-3 to omega-6 ratio, since modern diets tend to be heavily weighted towards omega-6 from processed foods and vegetable oils
• Have an interest in supporting normal cholesterol levels as part of a balanced diet and lifestyle

If you have a specific health condition or are taking medication, it’s always worth a conversation with your healthcare professional or a registered nutritional therapist before adding something new.

How Does Sacha Inchi Compare to Other Plant-Based Omega-3 Sources?

There are several good plant-based ways to get ALA into your diet. 

Here’s how sacha inchi stacks up against the others:

Flaxseed oil: One of the most well-established ALA sources, with around 50 to 55 per cent ALA content. Widely available, well researched, and a solid choice.

Chia seeds: Rich in ALA as well as fibre and protein. Eaten as whole seeds rather than oil, so a different kind of addition to the diet.

Hemp oil: Contains both ALA and linoleic acid (omega-6), with a naturally balanced ratio between the two.

Walnuts: A food source of ALA alongside protein and polyphenols. Good to eat, harder to dose consistently.

Sacha inchi oil: Among the highest plant-based concentrations of ALA available, at up to 51 per cent, alongside omega-6, omega-9, and vitamin E. Its omega-3 to omega-6 ratio is unusually favourable compared to most plant oils, which is part of what makes it stand out.

Where Does Metabolics Source Its Sacha Inchi Oil?

Our sacha inchi oil comes from Peru, its native growing region, where the plant has been cultivated for centuries. As with every raw material we use, each batch undergoes identity testing at a GMP facility before it reaches our production floor in Devizes.

This is not a regulatory requirement for food supplements in the UK. We do it because we believe you should know exactly what you’re taking, and we hold ourselves accountable to that. It costs more, and it takes longer, but it’s the standard we have always applied, and we have no intention of changing it.

 

 

 

Your Questions About Sacha Inchi Oil, Answered

Is sacha inchi oil the same as fish oil?

No. Fish oil contains EPA and DHA, which are long-chain omega-3 fatty acids. Sacha inchi oil contains ALA, a plant-based omega-3. Both are sources of omega-3, but they are different forms with different properties and different authorised health claims. ALA must be partially converted by the body to produce EPA and DHA, and this conversion is limited, which is why they are not interchangeable.

Can sacha inchi oil replace fish oil?

For people following a plant-based diet or those who do not tolerate fish oil well, sacha inchi is a genuinely useful source of omega-3. It’s not a direct replacement for EPA and DHA, but it contributes meaningfully to overall omega-3 intake. 

What is ALA, and why does it matter?

ALA (alpha-linolenic acid) is an essential omega-3 fatty acid, which means the body cannot produce it and it has to come from what you eat or supplement. It contributes to the maintenance of normal blood cholesterol levels and acts as a precursor to the longer-chain omega-3s EPA and DHA, though the conversion rate is modest.

How much sacha inchi oil should I take?

Human trials have typically used 10 to 15ml of culinary oil daily, or around 1,000 mg of encapsulated oil. The authorised cholesterol claim for ALA requires a daily intake of 2g. As with any supplement, starting at the lower end and building up is sensible. Mild digestive discomfort can occur at higher doses or if taken on an empty stomach.

Cutting through the noise

There’s a lot of enthusiastic and occasionally unreliable information circulating about sacha inchi oil at the moment. What the research does show is genuinely worth paying attention to, particularly for anyone looking for a high-quality, plant-based source of omega-3 that has real evidence behind it.
