It's Just! - Vitamin C Powder, 100% Pure L-Ascorbic Acid, Food Grade, Immune Support, Homemade Cosmetics (11oz)

I bought this product based on many positive reviews, even though it was quite expensive for a vitamin C supplement. I just received it, mixed it with water, and tried it—but it tastes incredibly sour, making it undrinkable for me. It also doesn’t dissolve well in water. This has been the most expensive and unusable product I’ve ever purchased, and to make matters worse, it’s not eligible for return. Unfortunately, it's going straight to the bin

I’ve been looking for a "no-nonsense" source of C_6H_8O_6 (L-ascorbic acid) that avoids the fillers and "natural orange flavors" found in most commercial supplements. I chose the It's Just! 11oz pack because of its dual-grade versatility: it's pure enough for dietary immune support and fine enough to be used in homemade topical serums. Purity & Physical Properties • The "Tartness" Factor: Make no mistake, this is 100% pure acid. It is incredibly sour (as it should be). If you are looking for a "tasty" drink, this isn't it—but if you want a clean, bioactive dose without maltodextrin or sugar, this is the benchmark. • Granulation & Solubility: This is a fine, crystalline powder rather than large "salt-like" grains. I tested the solubility in 8oz of room-temperature water; it dissolved completely with just a few stirs, leaving no "grit" at the bottom of the glass. • Potency: Because this isn't buffered (like Sodium Ascorbate), it is highly bioavailable. Candid Peer Tip: If you have a sensitive stomach, I recommend taking this with a meal to mitigate the acidity. Skincare Versatility (DIY Serums) Many people buy this specifically for cosmetics. In my experience: • The "Grit" Test: Because the powder is so fine, it incorporates beautifully into water-based serums. It doesn't feel "scratchy" on the skin. • Freshness: Vitamin C oxidizes quickly once exposed to air and light. This 11oz bag is opaque and reseals tightly, which is vital for keeping the powder from turning yellow (oxidizing) and losing its efficacy. Pros & Cons ✅ Pros: • Total Transparency: "It's Just!" lives up to its name—no anti-caking agents or hidden ingredients. • Fine Mesh: Dissolves nearly instantly in liquids or lotions. • Huge Supply: 11oz provides roughly 311 servings at 1,000mg each. ❌ Cons: • Acidity: It is very sharp on the palate; not for those who dislike tart flavors. • Bag Seal: Like many fine powders, the "zip" track can get dusty. I recommend wiping the track with a dry cloth before sealing to ensure an airtight fit. Final Verdict If you value purity over flavoring, this is a pantry and vanity staple. Whether you’re "puckering up" for a morning immune boost or mixing a fresh batch of serum, the quality of this L-ascorbic acid is undeniable. It’s effective, pharmaceutical-grade, and remarkably cost-efficient.

Easy to use, but not too much or you could have very loose stools. I love that it is as pure as can be.

Good Vitamin C powder. I love how this is just pure Vitamin C. You only need 1/4 a teaspoon so this will last a long time. Doesn’t really have a flavor so I add it to my collagen drink every morning.

Great value for the price & size of the bag. It's much easier to buy like this than in 30 day tablets/capsules. I haven't noticed any changes (only been taking a few weeks), but it also hasn't upset my stomach, either. I will say, the flavor threw me off, but that was my fault. I was expecting an orange juice type flavor. It very much does taste like a natural orange juice, but there is zero sweetness & ALL the tart you can pack into one tiny 8oz glass! Get ready for some face puckering! It only startles you the first sip or two, but then it's alright. Absolutely going to buy more of this when I run out!

I love this vitamin C powder. I put it with my greens powder! I’ve been taking this ever since the beginning of Covid.
