insights Analysis
Natural Factors L-Lysine is formulated to deliver 1000mg of L-Lysine Hydrochloride per serving, utilizing two 500mg capsules. This dosage is widely recognized by nutritionists and in online reviews for its efficacy in supporting immune health, particularly in managing cold sore outbreaks, and contributing to the formation of collagen for healthy skin and hair. While Natural Factors is a reputable brand, the cost of $0.20 per serving for this dose places it at a disadvantage compared to numerous alternatives that offer comparable or higher dosages at a lower price point, impacting its competitiveness in the market. Despite this, consumers generally report positive results consistent with L-Lysine's known benefits.
- Comes from Natural Factors, a well-regarded and reputable brand in the supplement industry.
- Provides an effective dosage of 1000mg of L-Lysine per serving, which is commonly recommended for its benefits.
- Utilizes L-Lysine Hydrochloride, a widely recognized and highly absorbable form of the amino acid.
- The price of $0.20 per serving is considerably higher than many alternative L-Lysine products that offer similar or even higher dosages.
- Requires taking two capsules per serving to achieve the 1000mg dose, which might be less convenient for some users.
- While L-Lysine is generally well-tolerated, high doses may cause mild gastrointestinal discomfort such as nausea or diarrhea.
- Individuals with kidney or liver conditions should consult a healthcare professional before taking L-Lysine supplements.
- Pregnant or nursing women should seek medical advice prior to use.
