Several supplements are known to increase endorphin levels, which can help enhance mood and provide a sense of well-being:

1. Caffeine: This stimulant can increase endorphin release, improve neuromuscular function, vigilance, and alertness. It is commonly used in pre-workout supplements to enhance athletic performance¹.

2. Rhodiola rosea: This adaptogenic herb influences endorphin levels by affecting the stress-response system. It modulates neurotransmitters like serotonin and dopamine and has been shown to stimulate the synthesis, transport, and receptor activity of opioid receptors and peptides such as β-endorphins²³.

3. L-Tryptophan: As a precursor to serotonin, this amino acid can help elevate endorphin levels indirectly by boosting serotonin production, a neurotransmitter associated with feelings of well-being⁴.

These supplements may help increase endorphin levels, similar to DPA (D-Phenylalanine), though the mechanisms might vary slightly. If you're looking to purchase DPA and are having difficulty finding it, checking with local regulations or consulting a healthcare professional might provide clarity on its availability.
