Analysis

Natural Factors L-Carnitine 500 mg features L-Carnitine Tartrate, a well-absorbed and effective form of L-Carnitine, packaged in convenient capsules. While the 500mg dose is a good starting point for daily supplementation, it's consistent with many other products in the market. The brand, Natural Factors, is generally well-regarded for its quality control. However, with a price per serving of 29, it falls on the higher side when compared to similar L-Carnitine Tartrate products, potentially making it less competitive in terms of cost-effectiveness for long-term use.

Pros
  • Uses L-Carnitine Tartrate, a well-absorbed and effective form.
  • From Natural Factors, a brand with a good reputation for quality and natural ingredients.
  • The 500mg dosage offers flexibility for individual needs.
Cons
  • Higher price per serving (29) compared to many other 500mg L-Carnitine Tartrate supplements.
  • Only 60 servings per bottle, requiring more frequent repurchases than larger quantities.
Warnings
  • Consult with a healthcare professional if you have a history of thyroid issues or are taking thyroid medication, as L-Carnitine may affect thyroid hormone levels.
  • Mild gastrointestinal upset may occur, especially with sensitive individuals or higher doses.

Categories
L-Carnitine 75.0
As an L-Carnitine Tartrate product, it delivers the benefits expected from this form. However, its higher price point within the category reduces its comparative standing against more competitively priced alternatives.
Goals
Fitness 75.0
The L-Carnitine Tartrate form supports post-exercise recovery and may aid in reducing muscle soreness. The 500mg dose is effective for consistent daily use, though higher doses are often employed for more intense training regimens.
Weight Loss 70.0
L-Carnitine's role in fat metabolism makes it a relevant supplement for weight loss. However, its efficacy is maximized when combined with a caloric deficit and regular exercise, and the 500mg dose might be insufficient on its own for significant impact.
Heart Health 65.0
While L-Carnitine generally contributes to metabolic support beneficial for heart health, this specific form is not as targeted for cardiovascular conditions as L-Carnitine Fumarate. Its utility here is more general than specific therapeutic.
