Sisu Sisu - L-Lysine 500mg, 90 vcaps
Sisu L-Lysine - A naturally occurring amino acid that has shown good results in decreasing the recurrence rate of the herpes simplex virus. L-Lysine also helps promote the absorption of calcium, collagen formation, and production of enzymes. Also used in the prevention and treatment of Osteoporosis, L-Lysine may also be helpful in the healing of bones and for the maintenance of healthy, elastic skin.

What the research supports
Each capsule is 500 mg of L-lysine, an essential amino acid the body can't make itself. The label's six-a-day empties the bottle in 15 days.
Studies use 1000 to 3000 mg of lysine a day.
- Collagen production (evidence: limited, from mechanistic, small human study)
- Lysine is a building block the enzymes need to cross-link collagen fibres together. Human trials testing whether extra lysine improves that process are small and few.
- Calcium retention (evidence: limited, from mechanistic, small human study)
- Small studies find lysine helps the gut absorb more calcium and cuts how much is lost in urine, though the trials are few and haven't been repeated at scale.
- Grain-heavy diets (evidence: moderate, from dietary intake study, nitrogen balance study)
- Cereal grains run low on lysine before any other amino acid, so diets built on bread, rice and pasta without legumes or meat can fall short of it.

Is it right for you
Worth it if
- Diets built mainly on grains
- Lysine is the limiting amino acid in wheat, rice and corn, so a grain heavy plate with few beans or animal foods runs lower in it than in any other essential amino acid.
- Wants to fine tune the amount
- 500 mg per capsule steps cleanly to 1000, 1500 or 3000 mg without measuring a powder.
- Already taking vitamin C daily
- Vitamin C dependent enzymes act directly on lysine residues during collagen assembly, so the two feed the same step rather than two unrelated ones.
Look elsewhere if
- Eats meat, fish or dairy daily
- An omnivorous diet already delivers several grams of lysine a day. Put the money toward a nutrient your food is actually short on, such as vitamin D or magnesium.
- Wants one capsule a day
- At 500 mg each this is built for multi capsule dosing. A 1000 mg lysine tablet or a bulk powder gets you to the same daily amount in far fewer swallows.
What to expect
Nothing perceptible. Lysine is a building block, not an active you feel, so the honest expectation is that you are closing an intake gap over weeks rather than noticing a daily effect.
How it compares
- Compared with bulk L-lysine powder
- Capsules are pre measured, travel without a scoop, and let you hit 1500 or 3000 mg exactly without tasting anything. The tradeoff: Powder costs a fraction as much per gram at these amounts, and 90 capsules is only about 15 days at full label directions.
