Amaranth

Amaranth oil, extracted from Amaranthus species seeds, contains exceptionally high levels of squalene (up to 8%) along with phenolic compounds like sinapic acid that selectively inhibit NLRP3 inflammasome activation. These bioactives target inflammation via PI3K-Akt and MAPK pathways while providing complete protein with all nine essential amino acids.

Origin

Amaranthus spp., commonly known as Amaranth, is an ancient pseudocereal native to Central and South America, now cultivated globally in tropical and subtropical regions. Its seeds yield a nutrient-dense, golden-hued oil prized for its concentration of squalene, essential fatty acids, and antioxidants. Revered by ancient civilizations, Amaranth has evolved into a modern wellness staple for its comprehensive nutritional profile, supporting skincare, cardiovascular health, and inflammation reduction.

Potential benefits

Provides complete protein,**: supplying all nine essential amino acids to support muscle repair, endurance, and overall vitality.
Enhances skin hydration,**: elasticity, and barrier protection due to its high squalene content.
Supports cardiovascular health**: by regulating cholesterol and improving arterial flexibility through squalene, fiber, and phytosterols.
Promotes digestive and**: gut health with high fiber content, nourishing microbiome diversity and supporting intestinal regularity.
Reduces systemic inflammation**: and supports cellular repair via antioxidant-rich polyphenols, flavonoids, and vitamin E.
Contributes to bone**: strength and mineral density through its rich content of calcium, magnesium, and phosphorus.
Offers antimicrobial and**: healing benefits, particularly when applied topically.

How it works

Sinapic acid and other phenolic compounds in amaranth oil selectively inhibit NLRP3 inflammasome activation and target 132 inflammation-related pathways including PI3K-Akt and MAPK. Key molecular interactions involve GAPDH downregulating TNF-α while upregulating IL-10, with additional effects on ALB and IL-6 receptors. The high squalene content enhances skin barrier function through lipid membrane stabilization.

What the research says

Current evidence is limited to in vitro studies and network pharmacology analyses, with no completed human clinical trials providing quantified efficacy data. Laboratory studies demonstrate antioxidant activity reaching 0.923 mg TEAC/g in certain seed varieties using DPPH scavenging assays. LC-MS/MS analyses confirm the presence of bioactive phenolic acids and molecular docking studies support anti-inflammatory mechanisms. Human clinical trials are needed to validate therapeutic claims and establish effective dosing protocols.

Safety and interactions

Amaranth oil is generally recognized as food-safe with no specific drug interactions or contraindications documented in current literature. Antinutrients including phytic acid and tannins may reduce digestibility and bioavailability of certain nutrients, though levels vary by variety. Pregnant and breastfeeding women should consult healthcare providers before therapeutic use due to limited safety data in these populations. No adverse effects have been reported in available studies, but comprehensive safety profiling remains incomplete.

Suggested use

Available as whole seeds, flour, puffed grains, leaf powder, and seed oil.
Seeds are consumed cooked (porridges, soups, gluten-free flour) or as puffed grains.
Seed oil can be used as a finishing oil in culinary applications or applied topically for skincare.
Leaf extract is available in supplement form.
Topical application: Use oil directly on skin or blend into creams and serums.
Recommended dosage: 1–2 tablespoons (15–30g) of seeds daily, or 1 teaspoon of seed oil daily.
For leaf extract, 500–1,500 mg daily for antioxidant and bone health support.

Frequently asked questions

What is the squalene content in amaranth oil compared to other sources?

Amaranth seed oil contains up to 8% squalene, making it one of the richest plant-based sources of this compound. This concentration is significantly higher than most vegetable oils and comparable to shark liver oil without ethical concerns.

How do the phenolic compounds in amaranth oil reduce inflammation?

Sinapic acid and other phenolic compounds selectively inhibit NLRP3 inflammasome activation and target 132 inflammation-related pathways. These compounds work through PI3K-Akt and MAPK pathways, with GAPDH serving as a key node that downregulates TNF-α while upregulating anti-inflammatory IL-10.

What makes amaranth oil different from amaranth seeds nutritionally?

Amaranth oil concentrates the lipid-soluble compounds including high levels of squalene and fat-soluble vitamins, while seeds provide complete protein and water-soluble nutrients. The oil extraction process yields approximately 7-8% oil from seeds, concentrating bioactive lipid compounds up to 10-fold.

Can amaranth oil be used topically for skin conditions?

The high squalene content in amaranth oil makes it suitable for topical application to enhance skin barrier function and hydration. In vitro studies support its anti-inflammatory properties, though clinical trials specifically testing topical amaranth oil for dermatological conditions have not been completed.

Are there any antinutrients in amaranth oil that affect absorption?

Amaranth oil contains lower levels of antinutrients like phytic acid and tannins compared to whole seeds, as these compounds are primarily water-soluble and remain in the seed meal during oil extraction. However, some fat-soluble antinutrients may still be present and could potentially affect bioavailability of certain nutrients.

How much amaranth oil should I take daily for cardiovascular and skin health benefits?

Typical dosing ranges from 1–2 teaspoons (5–10 mL) of amaranth oil daily, though some studies use up to 3 teaspoons for cardiovascular support. Start with a lower dose to assess tolerance, and consult a healthcare provider to determine the optimal amount based on your individual health goals and current diet. Consistency over several weeks is generally needed to observe measurable improvements in cholesterol levels or skin elasticity.

Is amaranth oil safe to use during pregnancy and breastfeeding?

Amaranth oil is likely safe in food amounts during pregnancy and breastfeeding due to its nutritional profile and long history as a food staple, but supplemental doses should be discussed with your obstetrician first. The complete protein and essential fatty acids in amaranth can support fetal development and postpartum recovery when used appropriately. Individual medical circumstances may warrant caution, so professional guidance is recommended before adding supplements to a prenatal or nursing routine.

Does amaranth oil interact with blood pressure or cholesterol medications?

Amaranth oil may have additive effects with blood pressure and cholesterol-lowering medications due to its phytosterol and squalene content, potentially enhancing their efficacy or requiring dose adjustments. If you take statins, ACE inhibitors, or other cardiovascular drugs, inform your doctor before using amaranth oil supplements regularly. Monitor your blood pressure and lipid levels closely, as combining dietary interventions with medications requires medical oversight to prevent over-treatment.
