NOW's L-Cysteine: No info on its source. Is it from human hair?

Posted by iHerb Customer on Jul 14, 2012 | Verified Purchase

I bought this as an alternative to NAC for liver detox and support, because it is good to pause or alternate ALL supplements. Now I discovered on Dr. Mercola & Wikipedia that 80% of it is made from hair swept up in chinese barbers. Then from duck feathers and hog hair. It can also be made from fermentation, but is 3X as expensive. Some sites also say it is a brain excitent which eventually burns out the brain if taken in high doses. On NOW's site, they offer no info on their source, but offer the absolute cheapest L-Cysteine. Anyone know of a non- hair source? I give it 3 stars until I know more. Also of concern is the general lack of details re ingredients on their labels. For instance: There are over 4 kinds of vitamin K-4. Menaquinone 4, 7,8 and 11. Only the Menaquinone 7 is of true value for humans. The others are inexpensive or synthetic forms of no true value. Now Foods has a large number of vitamin supplements that avoid telling us exactly what we are getting. And I am getting more suspicious of this company for this evasive strategy.

Something that finally seems to be working against hair loss

Posted by iHerb Customer on May 20, 2013 | Verified Purchase

I'm a female in my very early 30's and an inexplicable case of hair loss that no doctor or blood test seems to be able to detect 'medically'. Purchased NOW L-Cysteine after my dermatologist recommended it to me as a non medical solution. Seems to be working after 5 months of religious use - new hairs are sprouting all over my head.

Thanks for your feedback!

Hangover cure, huge tablet

Posted by iHerb Customer on Mar 02, 2011 | Verified Purchase

Been taking this with grape juice and thiamine(B1) the nights I go drinking and the combo is working. Last time I drank over 10 servings(I drink this much maybe 5 times a year so I don't have real tolerance) combo and went straight back to school after 7 hours of sleep as usual. The capsule is about the size of largest soft gel -capsules I've seen.

Not vegetarian

Posted by iHerb Customer on Dec 28, 2013 | Verified Purchase

I have to say I'm rather upset. The description of this product is misleading (including terms like (vegetable source) and vegetable coating,nowhere it is written that this is not suitable for vegetarians. I spent a good amount of time doing some research on the internet to find out where Now Foods L-Cysteine is derived from, after reading another review here of somebody wondering the same thing. Finally I found it on Now Food's homepage ( not under product description) but in a different section. L-Cysteine derived from Whey or Chicken Feathers. I feel defrauded, because in the way they put this product description it is not obvious at all that this is an animal based product - which by the way is fine - but being so vague and inexplicit gives me the impression that this is yet another company that most probably knowingly conceals the precise description in order to make some more bucks.

This is unbelievable product. I can`t believe how it made to look my hair. I am taking this with another product of now food Biotin, so it makes this one works even faster. My hair is growing faster and look much better. I love this product.

Thanks for your feedback!

Great product!

Posted by iHerb Customer on Aug 16, 2012 | Verified Purchase

This is a wonderful product! I have been using it for almost 6 months and after about 4 weeks I noticed an improvement with daily hair loss. I can honestly say that it has cut my hair loss by at least 50% and my hair is more abundant and the longest it has ever been (have not cut it in 31/2 months). This product has not changed the texture or diameter of my hair but hair loss, especially with hair washing, has improved beyond my expectations. I have not experienced any side effects such as the after taste that has been reported and I take it along with other antioxidants.

Thanks for your feedback!

Good Brand And Product, Works....

Posted by Read-Me-Now-Be-Happy on May 28, 2013 | Verified Purchase

Good for hair, skin, nails, scalp, connective tissue! We found that after using it for about a month we had noticeable results.

Thanks for your feedback!

It works.

Posted by JeongeunLee on Jan 25, 2011 | Verified Purchase

If you need 'brighter skin' without 'expensive brightning creams', get this one.(I`m korean) It really works.

Thanks for your feedback!
