Ideal for precise dosing with a pocket scale, it supports both culinary and supplement needs, making it a must-have for health-conscious professionals seeking premium quality and reliability. ## Description DosagesIt is recommended that men over the age of 18 consume 90mg of Vitamin C per day while for women over the age of 18 should consume 75mg per day. While slightly larger amounts of Vitamin C may not be harmful, usually consuming more than the needed Vitamin C will simply pass through the body without adequate processing. If very large amounts are consumed (over 2000mg) then it can actually harm the body. How much is in a teaspoon?This is a very common question. However, knowing how much is in a teaspoon is not very useful for measuring a daily dosage since a teaspoon contains over a month worth of nutritional value. A teaspoon amount is only useful for cooking recipes or when dividing the ascorbic acid into the volume of something bigger to be consumed over time (a container of water that can be measured again into smaller quantities). For direct daily intake, a pocket scale should be utilized for measuring out the milligrams (1000mg = 1g). In case you need to know how much is in a teaspoon, see the "density" paragraph below. DensityThe density of the 80 mesh ascorbic acid powder varies between 0. 9-1. 2 g/ml. There is about 5 ml in 1 US teaspoon. So there is a range of 4. 5g-6g, or 4500-6000mg of ascorbic acid per teaspoon. If you are an adult male that needs 75mg of ascorbic acid, a teaspoon results in at least 6000% of your daily needed intake. To take the proper amount, you would need to consume no more than 1. 67% of a teaspoon. This is impossible to measure and so we recommend to either mix this teaspoon into something else and divide that food up appropriately or to use a pocket scale with 0. 01g reading accuracy to measure it out. ## Features - 99+% Pure L-Ascorbic Acid, Chemical Formula: C6H8O6, A form of Vitamin C - Manufactured by A Registered Facility, Meets United States Pharmacopeia specifications, Food Grade BP2012/USP36 Bioactive, Non-GMO! - Packaged in a Heavy-Duty 5 mil/120um Light Resistant, PE/Aluminum/Nylon Resalable Bag - Flexible & Strong! - Synonyms: Vitamin C, Ascorbic, Vicodin C, Ascorbate, Ascorbutina, Catavin C, Cevex, Secorbate, 3-Keto-L-gulofuranolactone; 3-oxo-L-gulofuranolactone! - White Crystalline Powder / 80 Mesh / 177 Micron, Current Batch Expiration Date: November 2016 ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B003EE5MZC | | Best Sellers Rank | #1,024 in Vitamin C Supplements | | Date First Available | 6 September 2014 | | Is Discontinued By Manufacturer | No | | Item Model Number | asc1f | | Manufacturer | Duda Energy | | Product Dimensions | 19.56 x 15.24 x 3.56 cm; 453.59 g | ## Product Details - **Brand:** Duda Energy - **Item form:** Powder - **Diet type:** Keto - **Flavour:** Unflavored - **Product benefits:** immune_support ## Images ![L-Ascorbic Acid Powder 99.98+% Food Grade USP/BP Naturally Fermented Pure White Crystals Form of Vitamin C - Choose Size 1 lb Bag asc1f 1 - Image 1](https://m.media-amazon.com/images/I/81lE1kVNR0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality to make Pauling Vitamin C supplement *by on Reviewed in the United States 7 August 2011* I've always been a believer in Vitamin C to prevent and get rid of colds. (Of course the most effective way to not catch colds is to not touch your hands to anywhere on your face until you wash them after being around people or objects handled by people.)Earlier this year I learned it is important for the heart since it fights inflammation.I studied the online research by Linus Pauling, who won multiple nobel prizes. He is called the Father of Vitamin C. I wanted to mix up his specific formula for a liquid Vitamin C supplement using l-ascorbic acid, aluminum-free baking soda, and water.The quality of this L-ascorbic acid is good. I try to remember to take my Pauling liquid formula every day with each meal. I know it works, because I started to get the sore-throat symptoms when I was forgetting to take it. Since it is in the frig, it is a case of out of sight, out of mind. It was that bad sore throat where it feels like a gland getting very tender and sore. I immediately made a fresh batch and the symptoms were gone after a couple of doses. It works much faster than the vitamin C pills I took before.By the way, his formula is in grams. You can use a free converter on the Internet to convert grams to ounces and also a converter to convert to tablespoons. I then cut his formula in half so I mix it up fresh more often (lasts longer than a week). Tip: make it in a large bowl first before pouring in a bottle because the baking soda really foams up. Store it in a brown bottle to keep the refrigerator light out of it. Vitamin C is sensitive to light. Also, keep your L-asscorbic acid powder in a dark, sealed container. I roll the bag of L-ascorbic powder in such a way to force the air out as much as possible, then place it in a dark container. If you don't have a dark container, just wrap the bag in foil after rolling the bag.UPDATE: Apparently it is better not to go for cheaper L-ascorbic acid. After I used all of this brand, I bought one from a different company that gave me double the amount for a little less money. When it arrived, I noticed a slightly different texture, but it was packaged beautifully in foil that keeps out the light. However, after taking it every day for two months, I was exposed to a cold. Next thing I know, I had the worse cold I've had in years. Obviously, the product was inferior. So I recommend this one on Amazon because I never got a cold while using it. ### ⭐⭐⭐⭐⭐ Skincare *by on Reviewed in the United States 7 November 2025* I actually put this into my bath water. And I loved it. Topical vitamin C is so good for your skin. There are so many products for baths and face serums that advertise it, but in reality are primarily other, questionable, ingredients. Finding something that's about as close to pure as you can get in manufacturing was awesome. It dissolved very well. I put a couple tablespoons in to a full bath. I noticed a slight metallic scent but it didn't bother me at all and my skin felt very nice after a 20 minute soak. I'd like to try dissolving it into a carrier oil for my face next. ### ⭐⭐⭐⭐⭐ Good for post swimming chlorine neutralization *by on Reviewed in the United States 12 June 2016* I purchased this Acsorbic Acid to make my own post-swim chlorine neutralizer spray, because paying $6 for a 6oz bottle doesn't make any sense to me when I can just make the stuff fresh whenever I'm going to swim.The bag is kind of a pain to get rezipped, but it's great at blocking out the light, which will degrade the vitamin c over time.I use 1/8tsp in a dry 2oz spray bottle, and I take a bottle of water with me, so I can mix it up the moment I need to use it. It mixes well after about 10-15 seconds of shaking, and doesn't recrystallize after being sprayed on the hair and skin. It has done well in terms of neutralizing the chlorine, so it's not a bunk product, and it leaves no residue after rinsing. I can't say that it's a definite, but it also seemed to help take the sting out of the sunburn I got while swimming.It's a cost-effective product for external applications for sure. I don't lack vitamin c in my diet but I did try a little of this powder mixed in water, and it didn't taste like death, which is nice. Give some to the pirate in your life, if they're prone to scurvy. ## Frequently Bought Together - Duda Energy L-Ascorbic Acid Powder 99+% Food Grade USP36/BP2012 Naturally Fermented Pure White Crystals Form of Vitamin C, 1 lb. - AOZITA 4 Pack, 2 oz Dropper Bottles with 1 Funnel & 4 Labels - Essential Oils Bottles for Health, Personal Care & Beauty - 60ml Thick Dark Amber Glass Tincture Bottles with Eye Droppers, Leakproof - AOZITA Set of 4, 1 oz Eye Dropper Bottles with 1 Stainless Steel Funnels & 4 Labels - 30ml Thick Dark Amber Glass Tincture Bottles - Leakproof Essential Oils Bottle for Storage and Travel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/321102665-l-ascorbic-acid-powder-99-98-food-grade-usp-bp](https://www.desertcart.jp/products/321102665-l-ascorbic-acid-powder-99-98-food-grade-usp-bp) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-22*
