insights Analysis
Natural Factors L-Lysine 500 mg offers 500mg of L-Lysine Hydrochloride per capsule, but indicates a serving size of 2 capsules to provide a 1000mg dose. This 1000mg daily dose is highly effective for supporting immune health, promoting collagen formation for skin, and aiding in hair protein synthesis. While Natural Factors is a well-regarded brand, known for quality and purity, its price per serving of 16 cents for the 1000mg dose is notably higher than many other available L-Lysine options. This makes it a less competitive choice for budget-conscious consumers, despite its efficacy and brand reputation.
- Offers an effective 1000mg daily dose (two 500mg capsules).
- From Natural Factors, a reputable brand in the supplement industry.
- Capsule form is generally easy to consume.
- High price per serving (16 cents for 1000mg), making it less cost-effective.
- Requires two capsules for the optimal 1000mg dose, which can be less convenient.

bolt Effectiveness for goals
Lysine is commonly used to help prevent and treat cold sores, which are caused by the herpes simplex virus (HSV-1). Studies suggest it may interfere with the virus's ability to replicate, potentially by altering the balance of amino acids needed for viral growth. This action can lead to reduced frequency, severity, and healing time of outbreaks.
As an essential amino acid, Lysine is a fundamental building block for proteins in the body. It is crucial for the synthesis of collagen, which is vital for connective tissues like skin, bone, and cartilage. This role directly supports muscle repair and growth, especially after exercise.
Yes, Lysine is known to play a role in calcium absorption and retention within the body. It helps to transport calcium, making it more available for bone formation and maintenance. This property contributes to its potential benefit for overall bone health.
Some preliminary research suggests that Lysine may have an anxiolytic (anxiety-reducing) effect. Studies, particularly those involving humans under stress, indicate it might modulate stress responses and reduce cortisol levels. However, more extensive research is needed to confirm these effects.
Lysine is essential for the formation of collagen, a key protein critical for skin and connective tissue structure. Adequate Lysine levels are therefore important for the body's natural wound repair processes. It aids in tissue regeneration and strengthening of new tissue.
schedule Dosage, timing & forms
Typical dosages for L-Lysine vary based on individual needs and the intended purpose, often ranging from 500 mg to 3000 mg per day. It is common for this to be divided into multiple doses throughout the day. Always follow the specific instructions on the product label or consult with a healthcare professional for personalized advice.
L-Lysine can generally be taken with or without food. Some individuals prefer taking it on an empty stomach to potentially enhance absorption, while others take it with meals to minimize any potential digestive discomfort. It is best to follow the directions provided on your specific supplement's label.
For general health, an adult daily dose often ranges from 500 mg to 1000 mg. However, specific dosages can vary depending on individual needs and health goals. Always follow product label instructions or consult a healthcare professional for personalized guidance.
While general supplement dosages typically range up to 3 grams (3000 mg) daily, higher amounts have been explored in specific research contexts. It is important not to exceed the dosage recommended on your supplement's label or by a healthcare professional, especially for long-term use. Excessive intake could potentially lead to side effects.
L-Lysine is widely available in several forms, including capsules, tablets, and powder. Liquid forms are also available, though less common. The choice of form often depends on personal preference, convenience, and desired dosage flexibility.
health_and_safety Safety & interactions
For general use, doses of 500 mg to 3 grams per day are commonly used and often considered safe. For specific conditions like cold sore management, higher short-term doses might be used under professional guidance. Always follow product label instructions or a healthcare provider's advice.
Lysine is generally well-tolerated at recommended doses. Mild side effects may include stomach pain, diarrhea, and nausea. If severe or persistent symptoms occur, discontinue use and consult a healthcare professional.
Lysine may interact with arginine supplements, as they compete for absorption in the body. It might also potentially increase the absorption of calcium, which could be relevant for individuals taking calcium supplements or certain diuretics. Always discuss all supplements and medications with a healthcare provider.
There is insufficient reliable information about the safety of taking lysine supplements during pregnancy or breastfeeding. It is generally advised for pregnant or breastfeeding individuals to avoid lysine supplementation unless specifically recommended and monitored by a healthcare professional. Prioritize consulting a doctor before use.
Lysine may potentially increase the absorption of calcium in the body. While this might be beneficial for some, individuals with hypercalcemia or those taking high doses of calcium or vitamin D should monitor their calcium levels. Discuss this with a healthcare provider, especially if you have pre-existing conditions.
