Curcumin vs Turmeric: What’s the Difference – and Why Does Bioavailability Matter?

Turmeric has become one of the most recognisable botanical ingredients in the supplement world. You will find it in powders, teas, capsules and concentrated extracts – often with very different amounts of active compounds.

But turmeric and curcumin are not the same thing, and two products that both say “turmeric” on the label can deliver very different formulations.

Another important question is bioavailability. Curcumin is naturally difficult for the body to absorb, which is why modern supplements increasingly use specialised delivery technologies.

In this guide, we explain what curcumin is, how it differs from turmeric, why absorption matters, and how Pharma Nord Curcumin with patented Longvida® technology approaches the bioavailability challenge.

What Is Turmeric?

Turmeric, botanically known as Curcuma longa, is a plant belonging to the same botanical family as ginger.

Its underground rhizome – commonly referred to as turmeric root – has been used as a spice for centuries and is responsible for the characteristic yellow-orange colour of curry powder.

The root naturally contains many different plant compounds, including a group known as:

Curcuminoids

Curcumin is the best-known member of this group.

According to Pharma Nord, turmeric root naturally contains approximately 2–5% curcumin, although the amount varies depending on growing conditions.

Turmeric vs Curcumin: Are They the Same?

No.

A simple way to understand the difference is:

This distinction becomes especially important when comparing supplements.

A capsule containing 400 mg turmeric powder is not necessarily equivalent to a capsule containing 400 mg turmeric extract, and neither figure tells you the curcuminoid content unless it is specifically declared.

What Are Curcuminoids?

Curcuminoids are naturally occurring polyphenolic compounds responsible for much of turmeric's distinctive yellow-orange colour.

Curcumin belongs to this family of compounds.

When comparing curcumin supplements, it is therefore useful to look beyond the total number of milligrams shown prominently on the front of the package and check how much curcuminoid the recommended serving actually provides.

This is particularly relevant with Pharma Nord's formulation.

One capsule contains:

400 mg Longvida® Turmeric Root Extract

providing:

100 mg Curcuminoids

The two figures should not be confused: 400 mg refers to the complete Longvida® turmeric-root extract, while 100 mg is the declared curcuminoid content.

Why Is Curcumin Bioavailability Important?

Curcumin presents an interesting formulation challenge.

According to Pharma Nord, untreated curcumin is fat-soluble and is poorly absorbed in the aqueous environment of the digestive tract.

This means that simply putting a large quantity of ordinary curcumin powder into a capsule does not automatically tell you how much curcumin becomes available to the body.

That is why the term:

Bioavailability

is so important when discussing curcumin supplements.

Bioavailability broadly refers to how much of a substance becomes available to the body after it has been consumed.

With curcumin, manufacturers have developed several formulation strategies designed to address its naturally limited absorption.

Why Do Some Curcumin Supplements Contain Black Pepper?

If you have compared turmeric supplements before, you have probably noticed that many contain:

Black Pepper Extract

or:

Piperine

Piperine is a constituent of black pepper and is frequently combined with curcumin in supplement formulations intended to increase its bioavailability.

However, it is not the only approach.

Different manufacturers use different delivery systems, including lipid-based formulations.

That is where Longvida® differs from many conventional turmeric-and-black-pepper products.

What Is Longvida® Curcumin?

Longvida® is a patented curcumin formulation developed to improve the bioavailability of curcumin.

The formulation used by Pharma Nord is based on:

Solid Lipid Curcumin Particles – SLCP

Rather than simply combining conventional curcumin extract with black pepper, the curcuminoids are incorporated into a lipid-based delivery system.

Pharma Nord describes the technology as embedding curcuminoids in small spherical lipid structures or solid lipid particles using a combination of lipids, emulsifiers and antioxidant components.

The formulation is patented in Europe under EP 1 993 365 and Longvida® is a registered trademark of Verdure Sciences.

Longvida® vs Standard Curcumin + Piperine

The distinction is mainly about the formulation strategy.

This does not mean that every piperine-containing curcumin supplement is inferior. They are simply different approaches to the same formulation challenge.

For shoppers who specifically prefer a curcumin supplement without black pepper or piperine, Longvida® offers an alternative lipid-based approach.

How Much Curcumin Is in Pharma Nord Curcumin?

Each capsule provides:

The recommended daily serving is:

1 Capsule Daily

Therefore, one capsule supplies the complete recommended daily portion.

A pack containing 50 capsules provides:

50 Daily Servings

when taken according to the manufacturer's recommendation.

Is More Curcumin Always Better?

Not necessarily.

When comparing supplements, it can be tempting to choose the product with the largest milligram number on the label.

With curcumin, however, that can be misleading.

For example, you may see one product advertising 1,000 mg of turmeric powder and another containing a smaller quantity of a specially formulated extract.

Those numbers alone cannot tell you which formulation will provide greater systemic exposure.

Important factors include:

The type of raw material

Actual curcuminoid concentration

Delivery system

Bioavailability technology

Recommended daily serving

and the quality and documentation behind the finished formulation.

This is why it makes more sense to compare the complete formulation rather than simply comparing milligrams.

Does Pharma Nord Curcumin Contain Black Pepper?

No black pepper or piperine is listed in the official formulation.

Instead, the product uses the patented Longvida® lipid-based delivery system.

The official ingredient list is:

Turmeric Root Extract (Longvida®), Humectant: Edible Fatty Acids; Maltodextrin, Hydroxypropyl Methylcellulose, Emulsifier: Lecithins (Soy); Anti-Caking Agent: Silicon Dioxide; Antioxidant: Ascorbyl Palmitate; Anti-Caking Agent: Magnesium Salts of Fatty Acids.

This makes it particularly easy to distinguish from conventional curcumin + piperine formulas.

Is Pharma Nord Curcumin Vegan?

Yes.

According to the manufacturer, the formulation contains no animal-derived ingredients and is suitable for:

Vegetarians

and:

Vegans.

The capsule shell is made from hydroxypropyl methylcellulose (HPMC) rather than gelatin.

However, the ingredient list includes soy lecithin, so people with relevant allergies should check the label carefully.

Do You Need to Take Curcumin with a Fatty Meal?

Ordinary curcumin is fat-soluble, which is one reason dietary fat is often discussed in connection with turmeric supplements.

Longvida®, however, already uses a lipid-based formulation.

Pharma Nord states that although its Curcumin product remains predominantly fat-soluble, it can also be taken between meals because of the way the curcumin is formulated.

The manufacturer's recommended use is:

Take 1 Capsule Daily

with sufficient liquid, with any meal.

Always follow the instructions on the current product packaging.

What Should You Look for When Buying a Curcumin Supplement?

The front of a supplement package rarely tells the whole story. When comparing products, check:

1. Turmeric powder or concentrated extract?
These are not interchangeable.

2. How much curcuminoid does it actually contain?
Look beyond the headline turmeric-extract number.

3. What bioavailability system is used?
For example, piperine or a lipid-based delivery technology.

4. Is the formulation patented or clinically documented?
This can make it easier to identify exactly which ingredient formulation has been studied.

5. Does it contain black pepper?
This matters particularly if you specifically want a piperine-free formulation.

6. Is it suitable for your diet?
Check capsule material and other excipients rather than assuming every botanical supplement is vegan.

Pharma Nord Curcumin Longvida® at a Glance

The manufacturer describes the product as a high-bioavailability, clinically tested and documented Longvida® curcumin formulation.

Longvida® Curcumin or Regular Turmeric – Which Makes More Sense?

The answer depends on what you are looking for.

Turmeric as a food or spice is an excellent way to incorporate the whole botanical ingredient into your diet.

A standard turmeric supplement provides turmeric in a more convenient concentrated format.

A standardised curcumin extract allows you to know more precisely how much curcuminoid you are consuming.

And a specialised formulation such as Longvida® goes one step further by addressing the naturally limited bioavailability of curcumin through a patented lipid-based delivery system.

They are therefore not simply different doses of the same product – they are different ways of consuming turmeric-derived compounds.

Final Thoughts

When choosing a curcumin supplement, the biggest number on the package is not necessarily the most useful number.

It is worth asking three questions:

How many curcuminoids does it actually contain?

How is the curcumin formulated for absorption?

What exactly am I taking each day?

Pharma Nord Curcumin provides a clear answer to all three: 400 mg patented Longvida® turmeric-root extract providing 100 mg curcuminoids per capsule, delivered through a lipid-based SLCP formulation without relying on piperine. It is also suitable for vegan and vegetarian diets.

For shoppers comparing conventional turmeric capsules, curcumin + black pepper products and more specialised bioavailability formulations, understanding these differences is far more useful than simply comparing milligrams.
