Each bottle holds 100 capsules and the serving size is one capsule. It is manufactured by Life Extension.\u003c\/p\u003e\n\n\u003cp class=\"lgcc-faq-q\" id=\"lgcc-faq-how-much-glutathione\"\u003eHow much glutathione is actually in it?\u003c\/p\u003e\n\u003cp class=\"lgcc-faq-a\"\u003e50 mg of reduced L-glutathione per capsule, as Setria®. We want to be straight about that figure because it is the most misread thing about this product. Single-ingredient glutathione capsules commonly supply 250 mg to 500 mg per capsule, so 50 mg is a small fraction of that. The human trials on oral glutathione have generally used 250 mg to 1,000 mg per day. If a higher pre-formed glutathione dose is what you are after, the NOW Foods 500 mg product linked above is the better match.\u003c\/p\u003e\n\n\u003cp class=\"lgcc-faq-q\" id=\"lgcc-faq-cysteine-vs-nac\"\u003eWhat is the difference between L-cysteine and NAC?\u003c\/p\u003e\n\u003cp class=\"lgcc-faq-a\"\u003eThey are different compounds. This product contains L-cysteine hydrochloride, the amino acid in its salt form. NAC is N-acetyl cysteine, which is L-cysteine with an acetyl group attached. Both are sulphur-containing forms of cysteine and both are used as sources of cysteine, which the body uses as a building block in synthesising its own glutathione. NAC has the longer clinical research record of the two. Neither L-cysteine nor NAC holds an authorised EU health claim.\u003c\/p\u003e\n\n\u003cp class=\"lgcc-faq-q\" id=\"lgcc-faq-vitamin-c-claims\"\u003eWhat does the vitamin C in it do?\u003c\/p\u003e\n\u003cp class=\"lgcc-faq-a\"\u003eVitamin C is the one ingredient here that holds authorised EU health claims, and at 500 mg per capsule this product is comfortably above the threshold needed to use them. Under EU Regulation 1924\/2006, vitamin C contributes to the protection of cells from oxidative stress, to the normal function of the immune system, to the reduction of tiredness and fatigue, to normal energy-yielding metabolism, to normal collagen formation for the normal function of skin, bones, cartilage, gums, teeth and blood vessels, and it increases iron absorption. Those claims relate to vitamin C, not to the glutathione or the cysteine.\u003c\/p\u003e\n\n\u003cp class=\"lgcc-faq-q\" id=\"lgcc-faq-nrv\"\u003eWhy does your vitamin C percentage differ from the US label?\u003c\/p\u003e\n\u003cp class=\"lgcc-faq-a\"\u003eBecause the reference value differs between markets. The EU Nutrient Reference Value for vitamin C is 80 mg, so 500 mg is 625% NRV. Some US listings show 833%, calculated against the older US Daily Value of 60 mg. For a product sold in Ireland the EU NRV figure is the correct one, so that is what our panel shows.\u003c\/p\u003e\n\n\u003cp class=\"lgcc-faq-q\" id=\"lgcc-faq-legal-ireland\"\u003eAre glutathione and L-cysteine supplements legal in Ireland?\u003c\/p\u003e\n\u003cp class=\"lgcc-faq-a\"\u003eYes. Both are sold in Ireland as food supplement ingredients and are regulated by the Food Safety Authority of Ireland under food supplement legislation. Neither is classified as a medicine by the HPRA and no prescription is required. Separately from legality, neither compound has an authorised EU health claim, which is why this page describes composition and does not attribute benefits to either.\u003c\/p\u003e\n\n\u003cp class=\"lgcc-faq-q\" id=\"lgcc-faq-suitability\"\u003eIs it suitable for vegetarians or vegans?\u003c\/p\u003e\n\u003cp class=\"lgcc-faq-a\"\u003eThe capsule shell is vegetable cellulose, so the shell itself contains no gelatine. We are not currently labelling the product as vegetarian or vegan, and we would rather tell you why than tag it and hope. Commercial L-cysteine is produced either by microbial fermentation or from animal keratin, and the label does not state which route was used here. The label also lists stearic acid without naming its source. We have those two questions open with Life Extension. Until we have a written answer we will not apply a vegetarian or vegan claim to this listing.\u003c\/p\u003e\n\n\u003cp class=\"lgcc-faq-q\" id=\"lgcc-faq-how-many\"\u003eHow many capsules are in a bottle and how long does it last?\u003c\/p\u003e\n\u003cp class=\"lgcc-faq-a\"\u003e100 capsules.
