Health Guide
Macadamia Oil
Meet Macadamia Oil: the golden, buttery liquid often called 'the macadamia nut oil' (or sometimes 'Queen of Nuts oil'). Extracted from the nuts of the Macadamia tree native to Australia, this oil is a powerhouse of heart-healthy monounsaturated fats, specifically Omega-7 (palmitoleic acid). Unlike heavy cooking oils, it boasts a high smoke point and a light flavor. But why does it matter? It supports heart health, fights cellular inflammation, and gives your skin a radiant glow. It's a delicious, natural way to upgrade your health from the inside out.

Health Benefits & Sources
Why You Need It
- Heart Health Champion: Rich in monounsaturated fats (up to 80%) which help lower 'bad' LDL cholesterol.
- Skin & Hair Hydration: The Omega-7 fatty acids mimic your skin's natural oils, reducing dryness and irritation.
- Antioxidant Shield: Contains tocotrienols (a form of Vitamin E) that protect cells from oxidative stress.
- Blood Sugar Stability: Healthy fats slow digestion, preventing sugar spikes after meals.
Deep Dive
Macadamia oil is unique because of its high Palmitoleic Acid content. This Omega-7 fatty acid is naturally produced by the body, but levels drop as we age. By adding it to your diet, you are essentially replenishing a lipid that your cells use for communication and repair. It is also incredibly heat-stable, meaning it doesn't turn into toxic trans fats when you cook with it, unlike vegetable or seed oils.
Natural Food Sources
The best way to get these benefits is by consuming the whole nut or the cold-pressed oil. Since this is a specific nut oil, the primary source is the nut itself or extracted oil.
| Food | Amount | % DV (Daily Value) |
|---|---|---|
| Macadamia Nuts (Raw) | 1 oz (10-12 nuts) | High (Monounsaturated Fat) |
| Macadamia Oil | 1 Tablespoon | High (Palmitoleic Acid) |
| Avocado | 1 medium | Medium (Similar healthy fats) |
| Olive Oil | 1 Tablespoon | Medium (Different fat profile) |
Supplementation
While usually a culinary ingredient, Macadamia Oil is available in softgels as a dietary supplement.
- Usage: 1-2 tablespoons daily for cooking/salads, or as directed on the supplement bottle.
- Who should use it: Ideal for those on Keto/Paleo diets, or anyone looking to reduce inflammation without using fish oil.

Frequently Asked Questions
Yes! It has a very high smoke point (around 410°F/210°C), making it excellent for stir-frying and baking without breaking down into harmful compounds.
It has a mild, buttery, and slightly sweet flavor. It is much subtler than eating the nut itself and won't overpower dishes.
Yes. It is non-greasy and absorbs well. Apply a single drop to dry areas or mix with your moisturizer for extra hydration.
While safe for humans, macadamia nuts are **toxic to dogs**. Never feed your dog macadamia nuts or oil containing them.
Safety & Side Effects
Safety & Considerations
- Allergies: CRITICAL. If you have a tree nut allergy (especially peanut), avoid macadamia nuts and oil entirely. Reactions can be severe.
- Calorie Density: It is very energy-dense (about 120 calories per tablespoon). While healthy, consuming it in massive quantities without adjusting other fats can lead to weight gain.
- Interactions: Generally safe with no major drug interactions, but due to its blood-sugar stabilizing effects, monitor levels if you take insulin.
