What customers say
Customers appreciate the combination of magnesium and vitamin C in this product, highlighting its benefits for immunity, antioxidant properties, and ease on the stomach. Many users find it effective for improving sleep quality, reducing nerve twitching, and supporting overall health. The powder form is noted for its high quality but some find it inconvenient to dose compared to tablets. The taste is described as sour by some but manageable with extra water or mixing into drinks. There are mixed reviews on the product's convenience and taste, with a few customers preferring capsules over powder. Overall, the product is well-received for its effectiveness and quality.

Another source of vitamin.
Verified purchase
I take sodium ascorbate as my main source of vitamin C, sodium levels can get pretty high though. It’s nice to have a magnesium based vitamin C.

Doesn't mix perfectly. Usually always some clumps left over but is still very good.

I’ve been using this vitamin C for a while and I’m really happy with it. It feels gentle on my stomach compared to other vitamin C supplements. I like taking it daily to support my immunity and overall health. The quality is great and the powder mixes easily. Definitely a supplement I plan to keep in my routine.

good supplement. I really liked the effect, I feel the benefits. The ingredients in the composition are in good shape. I was pleased with the quality of the additive, and I also liked the packaging from this manufacturer. The taste and smell are neutral. I am very pleased. I advise all my friends to try this great service and try this magnesium

High quality product. The ingredients are good. It contains magnesium as well which is a great benefit. The dosage can be easily adjusted by making water solution. The solution is yellow and has some taste. The solubility is not as good as the sodium ascorbate but the magnesium content worth it.

Great for histamine sensitivity
Verified purchase
This product helps my cortisol issues and immune related issues. Benefits ppl who are sensitive to histamines. Don't really care for the taste but not a big deal. Pure ingredients and great quality and good size package for the price. Because serving size is fairly small it lasts for a long time.

Excellant and more gentle form of vitamin C
Verified purchase
Source Naturals, Magnesium Ascorbate is a great product for its value and ingredient. It offers a combination of magnesium and vitamin C that extend its benefits to the immunity system and muscle without irritating the stomach. its antioxidant properties are very effective for improving sleep quality, reducing nerve twitching, and supporting overall health. The powder form is high quality that allow you to adjust the dosage according to your health situation. The taste is unpleasant sour but can be managed by mixing into Juice. It is a better form of vitamin c with extra little Magnesium. I like it.
