Expert opinion

“We are well aware of the role of B vitamins and of how the gut works, yet we often forget about the liver, which does an enormous amount of work every day processing everything that passes through the small intestine. In the BestNAC formula I brought together N-acetyl-L-cysteine with glucoraphanin and sulforaphane from broccoli sprouts.”

About the ingredients

N-acetyl-L-cysteine

NAC is a form of the amino acid cysteine with an acetyl group attached. Cysteine is one of the amino acids the body can make itself, and it is also found in protein-rich foods such as eggs, poultry, dairy and pulses. In BestNAC one capsule provides 450 mg of N-acetyl-L-cysteine, of which 334 mg is L-cysteine.

Broccoli sprout extract

Glucoraphanin occurs naturally in cruciferous vegetables: broccoli, kale, Brussels sprouts, rocket and cabbage. Young broccoli sprouts contain considerably more of it than the mature vegetable, which is why the extract is made from sprouts rather than from florets. The extract in BestNAC is standardised to 1% glucoraphanin and 0.5% sulforaphane, so each capsule contains 1 mg of glucoraphanin and 0.5 mg of sulforaphane.

Why standardisation matters

A plant extract without standardisation tells you the name of the plant but not how much of the active compound is inside. Standardisation means the amount is declared and repeatable from batch to batch. It is the difference between knowing what you are taking and guessing.

Get to know the active ingredients of the BestNAC supplement

N-acetyl-L-cysteine:

A form of the amino acid cysteine with an acetyl group attached to the molecule. Cysteine belongs to the amino acids the body is able to make itself, and it also occurs in protein-rich foods such as eggs, poultry, dairy products and pulses. BestNAC provides 450 mg of N-acetyl-L-cysteine per capsule, of which 334 mg is L-cysteine.

Broccoli sprout extract:

Glucoraphanin is a compound naturally present in cruciferous vegetables, and young broccoli sprouts contain considerably more of it than the mature vegetable. The extract used in BestNAC is standardised to 1% glucoraphanin and 0.5% sulforaphane, which means each capsule contains a declared and repeatable amount rather than an unspecified quantity of plant material.

Cruciferous vegetables are the natural dietary source of glucoraphanin. Broccoli, kale, Brussels sprouts, rocket and cabbage on the plate are the foundation; an extract can supplement them, not replace them.

Recommended intake: 2 capsules daily after a meal, washed down with water.

Storage: at room temperature, in a dry place, out of reach of small children. Protect from moisture and light.

Precautions: do not exceed the recommended daily serving. A balanced diet and a proper lifestyle are important for the functioning of the human body. A food supplement must not be used as a substitute for a varied diet. Do not use in case of hypersensitivity to any of the ingredients. Pregnant women and breastfeeding mothers should consult a doctor before use.

Where are BestLab dietary supplements manufactured?

BestLab supplements are manufactured in Poland, in modern plants that meet the highest quality standards. The raw materials come from various regions of the world, and we select only those that meet our strict requirements for purity, effectiveness and quality.

Have BestLab supplements been tested?

Yes. Every batch undergoes detailed testing at JS Hamilton, an independent certification centre in Poland, for purity, composition and active substance content. We use standardised raw materials only, so each capsule contains exactly the amount declared on the label.

Does BestNAC contain gluten? Can it be used by people with coeliac disease?

Our supplements are completely free from gluten, so they can be used by people with coeliac disease and by anyone avoiding gluten for other reasons. Every batch is tested for the presence of gluten and lactose.

Can BestNAC be used during pregnancy?

Only after consulting a doctor. Pregnant women should always discuss any supplement with the doctor in charge before starting.

Can BestNAC be used while breastfeeding?

As in pregnancy, the decision should be made after speaking to a doctor.

Can I open the capsule and take the powder on its own?

It is possible, although we do not recommend it as a routine. N-acetyl-L-cysteine has a distinctly sulphurous taste and smell, which most people find unpleasant. If swallowing capsules is difficult, discuss a convenient way of taking it with a specialist.

What is NAC?

NAC is the common abbreviation for N-acetyl-L-cysteine, a form of the amino acid cysteine in which an acetyl group is attached to the molecule. Cysteine itself is one of the amino acids the body can produce, and it is present in protein-rich foods.

Unfortunately, the smell of the supplement is very unpleasant (some describe such a smell as 'chemical') and I only took two capsules. I have concerns about using it, probably unfounded, but I can't bring myself to. Which is a shame, because the ingredients are great for me. I just need information about where this smell comes from.

N-Acetyl-L-Cysteine with Broccoli Sprout Extract – BestNAC

BestNAC combines N-acetyl-L-cysteine with an extract of broccoli sprouts standardised for glucoraphanin and sulforaphane.

What is in the capsule

N-acetyl-L-cysteine, usually shortened to NAC, is a form of the amino acid cysteine in which an acetyl group is attached to the molecule. In BestNAC one capsule delivers 450 mg of NAC, of which 334 mg is L-cysteine itself.

The second ingredient is an extract of broccoli sprouts, standardised to 1% glucoraphanin and 0.5% sulforaphane. Glucoraphanin is the compound naturally present in cruciferous vegetables such as broccoli, kale and Brussels sprouts; sulforaphane is what it turns into.

Why we do not promise anything here

We describe what the product contains and in what amount, and we stop there. Neither N-acetyl-L-cysteine nor glucoraphanin has an authorised health claim in the United Kingdom, so we make none. The composition, the doses and the standardisation are stated plainly and you can judge them yourself.

A balanced diet and a proper lifestyle remain what matters most. A food supplement is an addition to them, never a replacement.
