Is this better than Omega-3?

Different job. Omega-3 is for brain, heart, and inflammation. Omega-7 is more specialized for skin and mucous membrane hydration. They complement each other.

Does it help with weight loss?

The marketing hype outpaces the science here. Some animal studies showed promise, but solid human evidence is lacking. Don't buy it for this reason.

Will it make my skin oily?

No, that's not how it works. It supports your skin's natural moisture barrier from the inside, which can actually help balance skin, not make it greasy.

What it does

Helps hydrate skin and mucous membranes from the inside out. Think dry eyes, dry mouth, and general skin health. Some early data suggests it helps with cholesterol too.

Does it work?

Maybe. 5/10. If you have persistent dryness issues and Omega-3 isn't cutting it, it's worth a shot. For general health, stick with fish oil.

Click through to the studies bar for the evidence base.

How much

Around 500mg to 1g of sea buckthorn oil daily. Make sure it's standardized for palmitoleic acid, the key Omega-7.

See the dosing guide below.

Cost

Mid-range. $35-50/month. It's a specialty oil, so it costs more than basic fish oil.

Compare formats before buying.

First 24 hours

Nothing. This isn't a stimulant. It needs weeks to build up in your system.

Some ingredients build up over weeks. Others act fast.

After weeks

After 4-8 weeks, you might notice less skin dryness and better moisture in your eyes and mouth. Cardiovascular effects are still being researched.

The compound effect of consistent dosing.

Safety

Generally safe. It can thin the blood, so check with a doctor if you're on blood thinners. Start with a low dose to see how your stomach handles it.

Check the cautions section if you have a pre-existing condition.

How it feels

A gradual increase in skin and membrane hydration. You won't 'feel' it kick in. It's more about what you don't feel anymore, like tightness or dryness.

Some ingredients you feel. Others just work in the background.

Quick answers · dose curve
Forms · food sources

What's the best source: sea buckthorn or macadamia nuts?

Sea buckthorn. It has a higher concentration of Omega-7 and a better overall fatty acid profile for supplementation.

Can I take this with my fish oil?

Yes. They target different things and are safe to take together. Just be mindful of the total oil intake if you have a sensitive stomach.

How long until I notice anything?

Be patient. It takes at least 4-8 weeks of consistent daily use to see potential benefits for skin or eye dryness.

Bottom line

1.0g is the number.

Most research uses 1.0g daily. Below 0.3g, you're probably wasting money. Above 2.0g, no extra benefit. The curve plateaus. Safe upper limit ~ 4.0g.

Macadamia Nuts

3.5oz (100g)

Reality check

Macadamia Nuts. You'd need to eat a handful of macadamia nuts daily, adding over 200 calories. The berries are extremely tart and hard to find. A supplement is more direct and practical.
