Medi-C Plus Medi-C Plus - Vitamin C & L-Lysine Formula w/Magnesium Ascorbate Berry Flavour, 1 kg
Medi-C Plus Vitamin C & L-Lysine Formula with Magnesium Ascorbate - Berry Flavour - Humans do not make Vitamin C like animals do, we need to supplement this essential vitamin to meet our daily needs. Vitamin C and Lysine work together to build collagen, which strengthens and holds together the coronary cells. Inadequate amounts of Vitamin C means poor collagen production. Coronary cells then fall apart just as bricks do without a good mortar. Coronary arteries, closest to the heart, receive the greatest pressure and without enough vitamin C the collagen weakens. This sets the stage for a heart attack. The work of Dr. Sydney Bush shows that vitamin C + lysine can help reverse the process.

Why people keep reordering it
Best suited to: wants high-dose vitamin c without stomach burn, building a collagen-support routine with lysine, needs a large, precise vitamin c dose without swallowing many pills.
What the research supports
One scoop mixes 2000 mg of vitamin C and 1300 mg of L-lysine into water or juice. The 1 kg tub lasts about seven months.
Vitamin C studies use 500 to 2000 mg a day; lysine studies use 1 to 3 g a day.
- Collagen formation (evidence: strong, from biochemical, human deficiency studies)
- Vitamin C activates the enzymes that link collagen strands together, and lysine supplies one of the amino acids used to build them. Together they're the raw materials and the trigger.
- Immunity (evidence: moderate, from randomized controlled trials, meta-analysis)
- Vitamin C helps white blood cells work and move to where they're needed. Regular intake at this dose has modestly shortened how long a cold lasts in some trials.
- Cold sores (evidence: mixed, from )
- Lysine may block a virus's ability to use the amino acid arginine it needs to replicate. Trials on whether that lowers cold sore frequency give inconsistent results.

Is it right for you
Worth it if
- wants high-dose vitamin C without stomach burn
- the magnesium ascorbate buffering is gentler on the gut than an equivalent dose of plain ascorbic acid.
- building a collagen-support routine with lysine
- vitamin C and lysine are both required for the body's collagen cross-linking process, and this combines both in one scoop.
- needs a large, precise vitamin C dose without swallowing many pills
- one 5 g scoop replaces what would otherwise be several capsules to reach 2000 mg.
Look elsewhere if
- just wants a basic daily vitamin C top-up
- a 500 to 1000 mg tablet or capsule of plain vitamin C is simpler and cheaper for general maintenance.this field name typo fix
- managing kidney disease or told to limit magnesium
- check with a doctor first since 210 mg of added elemental magnesium per scoop is meaningful on top of diet.
- avoids stevia or prefers unflavoured supplements
- look for a plain ascorbic acid or sodium/calcium ascorbate powder without stevia leaf.
What to expect
There is nothing to feel in the short term since vitamin C and lysine work as raw materials for ongoing collagen turnover, not as a fast-acting effect. Most people take it daily as part of a routine and would only notice a difference over weeks to months in things like wound healing or skin resilience, if at all.
How it compares
- Compared with plain ascorbic acid powder
- this product's magnesium ascorbate form is buffered, so it is easier on a sensitive stomach at the same 2000 mg dose. The tradeoff: you pay more per gram of vitamin C for that buffering, and you also take on 210 mg of added magnesium whether you need it or not.
- Compared with separate vitamin C and lysine supplements
- combining them in one scoop is more convenient and keeps the two doses matched to each other. The tradeoff: you cannot adjust the lysine and vitamin C doses independently since they are fixed in one formula.
