Sure, I'd be happy to help with any questions you have about Swanson's L-Arginine & L-Ornithine supplement. What would you like to know?

The effectiveness of L-Arginine and L-Ornithine in increasing the height of adolescents is not well-established, though there are some promising aspects related to growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels.

1. Growth Hormone and IGF-1 Production: Studies indicate that L-Arginine and L-Ornithine supplementation can increase levels of GH and IGF-1 in adults and strength-trained individuals¹². GH and IGF-1 are important for stimulating growth in bones and tissues, which could theoretically contribute to height increases.

2. Dietary Arginine and Linear Growth: A study focusing on children did suggest a significant association between dietary arginine intake and growth velocity³. This suggests that adequate intake of arginine could be beneficial for normal growth patterns in children.

3. Limitations and Concerns: Despite these promising findings, the direct impact of L-Arginine and L-Ornithine supplementation on height in adolescents has not been firmly established. There's a lack of targeted studies on adolescents, and most research involves other populations or focuses on general growth hormone response⁴. Moreover, excessive supplementation can have side effects like gastrointestinal discomfort⁵.

4. Caution with Supplementation: Notably, supplementation should be approached with caution, particularly in adolescents. The use of amino acids and hormones for growth should ideally be supervised by a healthcare professional to avoid potential side effects and ensure overall nutritional balance⁶.

In conclusion, while L-Arginine and L-Ornithine have potential benefits related to growth hormone levels that might impact height, current research is insufficient to conclusively recommend these supplements specifically for increasing the height of adolescents.
