Medi-C Plus Medi-C Plus - Vitamin C & L-Lysine Formula w/Magnesium Ascorbate, 150 vcaps
Medi-C Plus Vitamin C & L-Lysine Formula with Magnesium 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 - in convenient capsule form.

Why people keep reordering it
Best suited to: someone wanting high-dose buffered vitamin c, people specifically targeting collagen and connective tissue support, anyone already taking separate vitamin c and lysine capsules.
What the research supports
Five capsules a day deliver 2000 mg of vitamin C and 1300 mg of L-lysine. The 150-count bottle is a one-month supply.
Vitamin C studies use 500 to 2000 mg a day; lysine studies use 1 to 3 g a day.
- Collagen formation (evidence: strong, from human physiology studies, biochemical research)
- 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 )
- 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 wanting high-dose buffered vitamin C
- the magnesium ascorbate form is less acidic than plain ascorbic acid, so 2000 mg daily is easier on a sensitive stomach.
- people specifically targeting collagen and connective tissue support
- vitamin C and lysine are both required cofactors for collagen synthesis, and this pairs them at meaningful doses in one capsule.
- anyone already taking separate vitamin C and lysine capsules
- this consolidates both into a single 5-capsule daily dose instead of two separate bottles.
Look elsewhere if
- someone who just wants a basic daily vitamin C top-up
- a single 250 to 500 mg vitamin C capsule will cover general antioxidant needs without the lysine or the 5-capsule serving size.
- anyone on a sodium or mineral-restricted diet needing to track magnesium intake closely
- check with a pharmacist first, since this adds 210 mg of elemental magnesium daily on top of any other magnesium sources.
- people who dislike swallowing multiple capsules
- a single-capsule high-dose vitamin C or a powdered ascorbate would be easier to take than 5 vcaps a day.
What to expect
Vitamin C and lysine work at the level of ongoing collagen turnover, not a fast or noticeable effect. Any change in things like skin resilience or wound healing speed would show up over weeks to months of consistent daily use, not days.
How it compares
- Compared with plain ascorbic acid vitamin C
- the magnesium ascorbate portion here is buffered and gentler on the digestive tract at high doses. The tradeoff: buffered forms typically cost more per milligram of vitamin C than plain ascorbic acid.
- Compared with separate vitamin C and lysine supplements
- this combines both into one product at a fixed 400:260 mg ratio per capsule, simplifying the routine. The tradeoff: you can't adjust the vitamin C to lysine ratio independently if your needs for each differ.
