A buffered form of vitamin C that combines ascorbic acid with magnesium, providing 485mg of vitamin C and 36mg of magnesium per capsule. The buffering effect of the magnesium makes this form significantly gentler on the stomach than pure ascorbic acid, which can cause digestive discomfort, acid reflux or loose stools at higher doses. This makes magnesium ascorbate the preferred choice for anyone who finds standard vitamin C supplements too harsh.

Vitamin C is essential for immune function, collagen synthesis, iron absorption, wound healing, antioxidant defence and the production of neurotransmitters including serotonin and noradrenaline. At 485mg per capsule, a single capsule provides over 600% of the NRV. The magnesium component, while modest at 36mg, provides an additional benefit as a mineral that most people do not get enough of. The vegetarian capsule shell is hydroxypropyl methylcellulose.

Take 1 capsule 1 to 3 times per day with meals.

One capsule daily provides strong maintenance coverage. For immune support during illness or periods of high demand, 2 to 3 capsules daily (970 to 1455mg vitamin C) provides a therapeutic dose. The buffered form allows these higher doses to be tolerated without the digestive discomfort that equivalent doses of pure ascorbic acid can cause.

Spreading doses throughout the day is more effective than a single large dose, as vitamin C absorption decreases at higher single doses. Taking one capsule with each meal provides steady levels throughout the day. If taking alongside iron supplements, the vitamin C enhances iron absorption, making them an effective pairing.

Magnesium: glycinate vs citrate vs malate vs threonate?

Magnesium comes in several different chemical forms when sold as a supplement, and they are not interchangeable. They absorb at different rates and have different evidence bases for specific uses. Glycinate is well tolerated and absorbed via a different gut pathway than oxide, making it the typical default for general supplementation, sleep, and anxiety. Citrate is well absorbed but has a more pronounced laxative effect at higher doses. Malate fits energy metabolism contexts. L threonate is brain penetrant for cognitive applications. A 2022 systematic review in the journal Nutrition confirms that direct head to head trials comparing forms for specific clinical outcomes remain limited.
