Analysis

A full gram of L-lysine gives a meaningful and focused amino-acid serving. The short ingredient list makes the product easy to evaluate and use.

Vitamin B6 is much higher than needed as a simple lysine cofactor, while chloride does not materially strengthen the main purpose. The tablet format may be large because of the amino-acid amount.

It fits users who want straightforward lysine in a smaller bottle. Value remains reasonable, though the B6 amount should be considered alongside other supplements.

Who is it for
  • Adults seeking focused lysine supplementation
  • Users who prefer a smaller bottle
Best for
  • One-gram lysine servings
  • A simple amino-acid routine

Pros

  • Provides one gram of L-lysine
  • Simple formula
  • One tablet per serving

Cons

  • Vitamin B6 is unnecessarily high
  • Tablet may be large
  • No meaningful supporting nutrients beyond B6

Warnings

  • Long-term supplemental vitamin B6 can contribute to tingling or nerve symptoms when combined with other sources.
  • Lysine may cause stomach discomfort or diarrhea in sensitive users.
  • People with significant kidney impairment should discuss high-dose amino-acid supplementation with their clinician.

Nutrient quality

83 Highest impact

Lysine is supplied in a meaningful amount in a simple formula. The high pyridoxine amount is unnecessary for delivering lysine and weakens dose balance.

.

Ingredient transparency

82 Highest impact

Every active has a clear amount and specific name, but tablet excipients are not provided. Complete non-active ingredient details are not included in the supplied label data.

.

Customer satisfaction

69 High impact

The supplied average rating is favorable. Detailed firsthand feedback is unavailable, so recurring complaints and purpose fit cannot be assessed.

.

Value for money

82 Highest impact

The straightforward formula provides a substantial lysine serving at a reasonable cost. Minimal padding supports value, though the smaller package is less efficient.

Lysine · 1000 mg

L-lysine provides a useful structural amino acid and may support iron utilization relevant to shedding. The full amount is well aligned with daily use.

The lysine salt is not specified, while added vitamin B6 is unusually high for long-term support. Daily use supplies 21.25 mg of vitamin B6, which may increase nerve-damage risk when combined with other B6 sources.

Vitamin B6 (Pyridoxine Hydrochloride) · 21.25 mg OverallScore74
D+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB- Value

The 21.25 mg amount is well targeted, but pyridoxine hydrochloride is used without a riboflavin cofactor. A single tablet makes the exact dose and form easy to use. Value is ordinary for a simple product using precursor-form vitamin B6.

Lysine · 1000 mg OverallScore70
D Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB+ Value

The 1,000 mg single-tablet dose is well aligned with daily lysine use, although the label does not identify the lysine salt or a higher-purity source. The container provides a good amount of lysine for its cost. The added 21.25 mg of vitamin B6 is a notable long-term-use consideration because this dose may be unsuitable for some users.

Chloride · 241 mg OverallScore63
F Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyA+ Value

A meaningful chloride dose may contribute to electrolyte intake. The label does not identify the chloride source, which limits confidence in its mineral form and bioavailability. A tablet format requires breakdown before the chloride can dissolve, although the low cost per serving supports strong value.

L-Lysine Advanced 1500 mg

Country Life
<p>A larger lysine amount is paired with vitamin D in a focused tablet. Compared with L-Lysine 1000 mg, its higher lysine amount may address the original’s unusually high vitamin B6 amount and weaker serving value more directly, although the immune blend is undisclosed and hair relevance remains indirect.</p>
72 Performance

Super Amino Night

Source Naturals
<p>Substantial lysine and arginine amounts give the amino-acid blend practical depth. Compared with L-Lysine 1000 mg, its clearly disclosed lysine, arginine, and ornithine may address the original’s unusually high vitamin B6 amount and weaker serving value more directly, although vitamin B6 is elevated and carnitine is only a token addition.</p>

UltraClear Renew Vanilla Flavor

Metagenics
<p>A meal-style powder supplies protein, amino acids, active folate, methylcobalamin, and magnesium. Compared with L-Lysine 1000 mg, its broad protein and micronutrient coverage may address the original’s unusually high vitamin B6 amount and weaker serving value more directly, although lysine is modest, many specialty additions are small, and the serving cost is high.</p>

L-Lysine 1000 mg

Country Life
<p>A full lysine serving gives the focused formula a clear purpose. Its lower recurring cost than L-Lysine 1000 mg supports this category, although the added pyridoxine amount is unusually high for routine use.</p>

Super Amino Night

Source Naturals
<p>Clearly disclosed lysine, arginine, and ornithine provide broad amino-acid coverage. The supplied data does not show it costing less than L-Lysine 1000 mg; it is included because fewer than three eligible lower-cost candidates are available, and the hair-health fit is indirect and vitamin B6 is elevated.</p>

Water Away with Dandelion & Potassium

ZHOU
<p>Vitamin B6 and chloride are paired with dandelion and green tea in a water-balance formula. The supplied data does not show it costing less than L-Lysine 1000 mg; it is included because fewer than three eligible lower-cost candidates are available, and it contains no lysine and the diuretic herbs may promote dehydration or electrolyte imbalance.</p>

Chewable L-Lysine 600 mg Tangy Twist Chew

Country Life
<p>A chewable format supplies a useful lysine amount with vitamin D. Compared with L-Lysine 1000 mg, its easier-to-take lysine format may justify some of the higher recurring cost, although the immune blend is hidden and the lysine amount is lower.</p>

Super Amino Night

<p>Clearly disclosed lysine, arginine, and ornithine provide broad amino-acid coverage. Compared with L-Lysine 1000 mg, its multi-amino-acid design may justify some of the higher recurring cost, although the hair-health fit is indirect and vitamin B6 is elevated.</p>
