About This Product
This is the large bottle of Natural Factors NAC 1000 mg: 180 tablets, each holding a full gram of N-acetyl-L-cysteine. N-Acetyl-L-Cysteine acts as an antioxidant, by protecting against free radical damage, for the maintenance of good health in individuals under oxidative stress. At one tablet a day, the bottle covers roughly six months.
What Natural Factors NAC 1000 mg is licensed for
It is licensed for sale by Health Canada and bears NPN 80122276. The licence also lists:
- A supportive therapy in the treatment of inflammation of the respiratory system.
- Helps to relieve symptoms of chronic bronchitis.
What is inside each tablet
N-acetyl-L-cysteine, or NAC, is the amino acid L-cysteine carrying an extra acetyl group. The label calls it a free form amino acid, meaning it is supplied on its own and not bound into a protein. Cysteine is a sulphur-containing amino acid, and it is one of the three building blocks of glutathione, along with glycine and glutamic acid.
Each tablet contains 1,000 mg of N-acetyl-L-cysteine as the single medicinal ingredient. The non-medicinal ingredients hold the tablet together and coat it: microcrystalline cellulose, dicalcium phosphate dihydrate, hydroxypropylcellulose, carbohydrate gum, glycerin, silica, stearic acid and magnesium stearate.
Choosing between Natural Factors NAC products
Natural Factors makes NAC in three strengths at Vitasave. Here is how they line up:
| Product | NAC per unit | Form | Bottle sizes |
|---|---|---|---|
| NAC 1000 mg | 1,000 mg | Tablet | 180 (this one) or 90 |
| N-Acetyl-L-Cysteine 600 mg | 600 mg | Vegetarian capsule | 60 or 180 |
| N-Acetyl-L-Cysteine 500 mg | 500 mg | Vegetarian capsule | 90 |
The 90 and 180 counts of NAC 1000 mg share one tablet and one licence. The larger count simply means fewer reorders. Pick a capsule strength if you want a smaller amount per unit.
How to take it
The label dose for adults 18 and over is 1 tablet a day. Do not use it if you are taking antibiotics or nitroglycerin. If you are pregnant or breastfeeding, or have kidney stones or cystinuria, consult a health care practitioner before you start. The full directions and cautions are under How to Take.
Who it suits
Adults who already take NAC daily and want a single gram in one tablet, with a supply that lasts half a year. Anyone trying NAC for the first time may prefer the 90-tablet bottle.
