## Questions & Answers

**Q: Is it synthetic?**
A: Who knows? It doesn't tell us what the source of the vitamin c is. Ascorbic palmitate is synthetic and I think there's another one that also is synthetic oftentimes are found in vitamin c suppliments that say they're non-gmo. Who knows? Under ingredients it says none. Apparently there are no ingredients in this. I wouldn't buy it

### ⭐⭐⭐⭐⭐ Look where the ingredients are sourced.

The company claims it tests the ingredients that come from Chyna and meets all required standards. I'm sure it's a great product but i won't use mine because the ingredients.

### ⭐⭐⭐⭐⭐ 2500mg in 1/2 teaspoon. I do endorse this product. I recommend taking less than 1/2 a serving in a single day.
*by C***Y on April 28, 2014*

This product is now recommended in a new nutrition book called It's Not the Cans: The Best Nutrient Balance for a Stronger and Healthier You This is a potent product. 1/2 teaspoon equates to 25, 100 mg tablets in a single dose. I bought this product primarily to neutralize the chlorine and chloramines in my bath water. Based on the science, 1000 mg of vitamin C will neutralize 100% of the chlorine and chloramines contained in 100 gallons of water. This equates to 10 mg of vitamin C to completely neutralize the chlorine and chloramines in 1 gallon of water. The average bathtub holds approx. 30 gallons of water when full. This means that on average, you require only 300 mg of vitamin C to neutralize the chlorine and chloramines in a full tub. Of course, when we leave room for our body we do not completely fill the tub. ==> Let us assume we place 25 gallons of water in a tub to bathe in. That means we would need to add 250 mg of vitamin C to the water to neutralize 100% of the chlorine and chloramines. That equates to 1/10 of 1/2 of 1 teaspoon of this product!!!! ==> Let's say we want to be certain because your area may use a little more chlorine and chloramines to treat the water. So we decide to double the dose. This means we would add 500 mg of vitamin C to 25 gallons of bath water. This equates to 1/5 of 1/2 teaspoon of this product!!! ==> Let's be paranoid and go 4 times the amount of C for a 25 gallon tub, which equals 1000 mg. This equates to less than 1/4 teaspoon of this product!!! According to the label there are 181 servings (1/2 teaspoon) in this container which means even at 4 times amount needed for a 25 gallon bath, we have 362 baths in each bottle (that is after rounding up to a full 1/4 teaspoon)!!!! Not only do I bathe with this product, I also add a little to a large bowl of water when I choose to wash my hair in the sink. I use a cup to scoop out water to rinse my hair. After doing this and installing a chlorine filter in my shower, my scalp has completely stopped itching!!! Please note, vitamin C may cause hair des to fade quicker. If you choose to drink this product, I strongly encourage you to stay below 1/4 teaspoon per day. Please consider that 1/4 teaspoon is still 1200 mg of supplemental C. I get my C from strawberries and pure, organic orange juice as well as via a high quality multi-vitamin (Opti-Men). Excess vitamin C intake (300 mg or more) can be a causal factor for insomnia. You do not need much to be healthy. I highly recommend bathing in this product, shaving with this product added to the water, and washing your hair and face with this product. I also recommend installing a quality, chlorine shower filter. Please note that chorine filters do NOT remove chloramines. That is okay because removing the chlorine is still great for your hair, skin, and lungs. In case I forgot to say it, BUY THIS PRODUCT. You will not be disappointed.
