Glutathione products compared
| Product | Form | Capsule | Daily dose | Glutathione | Pack lasts |
|---|---|---|---|---|---|
| OstroVit Glutathione VEGE 200 mg, 90 capsules | reduced L-glutathione | vegetable (HPMC) | 1 capsule with a meal | 200 mg | 90 days |
| Swanson Glutathione 200 mg, 60 capsules | Setria, reduced L-glutathione | HPMC, brown rice flour filler | 1 capsule with water | 200 mg | 60 days |
The dose is the same, so the choice is about pack size, price per day and the ingredient list. Both products use a vegetable-type capsule shell, but check the full label if you follow a strict diet.
What glutathione is
Glutathione is a small molecule built from three amino acids: glutamic acid, cysteine and glycine. The body makes it itself. Supplements use the reduced form, often written GSH, which is the form the label here calls reduced L-glutathione. Setria is the trade name of one branded glutathione ingredient and it is listed on the Swanson label.
Reading the label
- Form: reduced L-glutathione, with the amount in milligrams per capsule.
- Daily dose: one capsule for both products.
- Fillers: maltodextrin for OstroVit, brown rice flour for Swanson.
- Allergens: OstroVit lists possible traces of milk, soy, nuts, gluten and others.
Health claims
The EU register of authorised health claims has no statement for glutathione. Under Regulation (EC) No 1924/2006 we therefore do not describe effects on the liver, skin, ageing or detox, and any page that does is going beyond what the EU allows. Our product pages give the dose, the form and the manufacturer warnings.
Before you buy
Both labels say the product is not for pregnant and breastfeeding women, and OstroVit adds that it is not for children. Do not exceed one capsule a day. If you buy several antioxidant-type supplements, see the mineral categories for selenium and zinc, and our coenzyme Q10 range, each with its own label and dose.
How to choose
Both products give 200 mg of reduced L-glutathione a day, so compare what is left: pack length, filler, capsule type and price per day. OstroVit gives 90 days from one pack and is taken with a meal. Swanson gives 60 days, is taken with water and names its Setria ingredient on the label. Take one capsule a day as printed and do not combine the two products, because that would double the dose.
Questions
When do I take glutathione?
OstroVit says one capsule a day with a meal, Swanson one capsule a day with water. Follow the label of the product you choose.

How long does a pack last?
At one capsule a day: 90 days for OstroVit, 60 days for Swanson.
