NOW Foods Glutathione 500 mg is a reduced L-glutathione supplement that many people use for antioxidant support and potential skin health. Reviews are generally mixed: some users report improved energy or skin appearance, while others see no noticeable difference. It is not FDA-approved to treat any disease, and you should talk to a healthcare professional before starting any new supplement.
What Is NOW Glutathione 500mg?
NOW Foods Glutathione 500 mg is a dietary supplement that provides 500 milligrams of reduced L-glutathione per capsule. Glutathione is a naturally occurring antioxidant made in the body from three amino acids: cysteine, glycine, and glutamic acid. It plays a role in fighting oxidative stress, supporting liver function, and potentially influencing skin health.
Oral glutathione supplements like NOW’s are popular because they are convenient and relatively inexpensive. However, absorption of oral glutathione is debated. Some research suggests that plain glutathione may be broken down in the digestive tract, while other forms like liposomal glutathione may have better bioavailability.
What Do Users Say in NOW Glutathione 500mg Reviews?
Online reviews for NOW Glutathione 500mg are mixed. Common positive themes include improved skin clarity, increased energy, and general antioxidant support. Negative reviews often mention no noticeable change, digestive discomfort, or the large capsule size.
Many users report that they chose NOW because of the brand’s reputation for quality and testing. When checking now glutathione price, you’ll find it is often more affordable than liposomal or specialty glutathione supplements. Some people compare it to a whitelight glutathione supplement, which may combine glutathione with other ingredients like vitamin C or collagen for skin support.
It’s important to remember that individual results vary widely. Glutathione supplements are not FDA-approved to treat, cure, or prevent any disease, and user anecdotes are not scientific evidence.
How Does NOW Glutathione Compare to Other Glutathione Supplements?
The glutathione supplement market includes several forms and brands. The table below compares NOW Glutathione 500mg with liposomal glutathione, whitelight glutathione, and glutathione nasal sprays.
| Product/Form | Key Features | Typical Dosage | Approximate Price Range |
|---|---|---|---|
| NOW Glutathione 500mg | Reduced L-glutathione, 500mg per capsule, vegetarian capsule | 1 capsule daily | $15–$25 for 60–120 capsules |
| Liposomal Glutathione | Glutathione encased in liposomes for potentially better absorption | 500–1000mg daily | $30–$60 for 30–60 servings |
| Whitelight Glutathione Supplement | Often combines glutathione with vitamin C, collagen, or other skin-supporting ingredients | Varies by product | $20–$50 per bottle |
| Glutathione Nasal Spray | Direct nasal delivery, bypasses digestion | 1–2 sprays per nostril daily | $25–$45 per bottle |
If you read liposomal glutathione reviews, many users report better absorption because the liposomal form protects glutathione from digestion. Terra health glutathione reviews often mention different dosages and added ingredients. Auro wellness glutathione reviews frequently discuss their unique delivery method, such as creams or patches. Glutathione nasal spray reviews describe a more direct route, but nasal sprays can irritate the nose.

The Bottom Line on NOW Glutathione 500mg Reviews
NOW Glutathione 500mg is a well-known, affordable reduced glutathione supplement. Many users appreciate the brand’s quality standards and the convenience of a 500mg capsule. However, scientific evidence for oral glutathione’s effectiveness is limited, and user reviews are mixed.
If you are looking for potentially better absorption, liposomal glutathione or other forms might be worth exploring. For skin-specific goals, a whitelight glutathione supplement or a product with added nutrients could be an option, but results are not guaranteed.
Ultimately, the best choice depends on your health goals, budget, and tolerance. Always discuss supplements with your doctor, especially if you have a medical condition or take medications.
