Medi-C Plus Medi-C Plus - Vitamin C & L-Lysine Formula w/Calcium Ascorbate Citrus Flavour, 1 kg
Medi-C Plus Vitamin C & L-Lysine Formula with Calcium Ascorbate - Citrus Flavour - Vitamin C and L-Lysine 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: people who get stomach upset from plain ascorbic acid, someone wanting a higher daily vitamin c intake without swallowing pills, people already using vitamin c and lysine together for connective tissue support.
What the research supports
One scoop gives you 2000 mg of vitamin C and 1300 mg of L-lysine, dissolved in 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.
- Collagen formation (evidence: strong, from human rct)
- Vitamin C is a required cofactor for the enzymes that stabilize collagen, and lysine is one of the amino acids collagen is built from. Together they supply both a building block and the enzyme helper that assembles it.
- Immunity (evidence: moderate, from mechanistic, human observational)
- 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
- People who get stomach upset from plain ascorbic acid
- The calcium and magnesium ascorbate here buffer the acidity compared to straight ascorbic acid powders.
- Someone wanting a higher daily vitamin C intake without swallowing pills
- One scoop dissolved in water delivers 2000 mg, replacing what would be several capsules.
- People already using vitamin C and lysine together for connective tissue support
- This combines both actives in fixed, high amounts in a single scoop instead of dosing them separately.
Look elsewhere if
- Anyone expecting this to treat or reverse a heart condition
- Work with your doctor on what actually moves it. Vitamin C and lysine at these amounts are a nutritional habit, and no powder replaces the care a diagnosis calls for.
- People on a low-sodium or fluid-restricted diet needing to limit calcium or magnesium intake
- Check with a pharmacist about the added calcium and magnesium load before using a large daily scoop of this powder.
- Someone who just wants a basic, low-dose daily vitamin C
- A plain 500 mg to 1000 mg vitamin C tablet or capsule would be simpler and cheaper for general topping up.
What to expect
There is nothing to feel directly from vitamin C or lysine in the short term; this is a nutrient-support product, not a fast-acting one. Any change in connective tissue or vascular collagen quality, if it happens, would take weeks to months of consistent daily use.
How it compares
- Compared with plain ascorbic acid powder
- The ascorbate forms here are less acidic and gentler on the stomach at high daily doses. The tradeoff: You pay more per gram of vitamin C than for plain ascorbic acid.
- Compared with separate vitamin C and lysine supplements
- This combines both in one measured scoop instead of tracking two products and two doses. The tradeoff: You can not adjust the vitamin C and lysine ratio independently since they are fixed together.
