Medi-C Plus Medi-C Plus - Vitamin C & L-Lysine Formula w/Calcium Ascorbate Unflavoured, 600 g
Medi-C Plus Vitamin C & L-Lysine Formula with Calcium Ascorbate - Unflavoured - Vitamin C & L-Lysine formula with Calcium Ascorbate. 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: someone who wants a high-dose vitamin c powder, people who dislike swallowing multiple large capsules, vegans or vegetarians avoiding animal-derived collagen supplements.
What the research supports
One scoop mixes 2000 mg of vitamin C and 1300 mg of L-lysine into water or juice. The 600 g tub lasts about five 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 )
- 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 small rcts)
- 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
- someone who wants a high-dose vitamin C powder
- 2000 mg per scoop is a concentrated dose in a buffered calcium ascorbate form that is gentler on the stomach than plain ascorbic acid alone.
- people who dislike swallowing multiple large capsules
- a single scoop dissolved in water replaces what would otherwise be several vitamin C and lysine capsules.
- vegans or vegetarians avoiding animal-derived collagen supplements
- the formula uses calcium ascorbate and synthetic L-lysine hydrochloride with no animal ingredients.
Look elsewhere if
- anyone expecting this to reverse existing artery damage
- talk to a doctor about cardiovascular care directly, since the vitamin C and lysine collagen theory referenced here has not been established through controlled human trials.
- people already getting enough vitamin C from diet and other supplements
- a lower dose vitamin C product, such as 250 to 500 mg, avoids stacking near the 2000 mg upper intake level.
- someone on a sodium or calcium restricted diet needing a plain ascorbic acid form
- look for a straight ascorbic acid or sodium-free vitamin C product instead of this calcium-buffered blend.
What to expect
Vitamin C at this dose is absorbed within hours and used immediately in collagen-building reactions, but you will not feel anything directly since it is a structural, cumulative nutrient rather than a stimulant. Any change tied to connective tissue support happens over weeks to months of consistent daily use.
How it compares
- Compared with plain ascorbic acid vitamin C
- the calcium ascorbate portion here is buffered and less acidic, which is easier on the stomach at high doses. The tradeoff: it adds 179 mg of calcium per scoop, which matters if you are already tracking calcium intake.
- Compared with separate vitamin C and lysine capsules
- this combines both into one dissolvable powder at a fixed 2000 mg to 1300 mg ratio, simplifying dosing. The tradeoff: you cannot adjust the two doses independently, and powder format means measuring a scoop rather than swallowing a capsule.
