Getting Back Into Rhythm: L-Tryptophan + B Vitamins for Autumn

Getting Back Into Rhythm: L-Tryptophan + B Vitamins for Autumn

ByEvan Parker

Summer in Cartagensis light, sea swims, kids running around till 10 PM. But autumn comes with a thud: school starts, rain returns, work piles up, and I’m back to my “remote + flights” rhythm. That’s when I look closer at routines, from sleep to supplements. One thing that often comes up in conversations with friends is L-tryptophan, especially paired with B vitamins.

Why It Matters

L-Tryptophan is an amino acid — the body can’t make it, but it uses it for serotonin (mood), melatonin (sleep), and even niacin (vitamin B3). In short: if your intake is low, your resilience to stress, jet lag, or gray rainy weeks can drop.

Adding vitamin B6 and B3 helps your body actually convert tryptophan into serotonin more effectively. That’s why many supplements in Spain combine them.

My Personal Caveat

I’ll say it straight: I don’t take tryptophan daily. I tried, but I don’t tolerate it well — headaches and strange dreams. That’s why I always add this warning: even though it’s “just a supplement,” talk to a doctor first. It’s not a magic pill, and it’s not for everyone.

Reviews of the Main Brands (Manufacturers)

HSN (España)
HSN is a Spanish nutrition and sports supplement company, known for relatively transparent labeling and local production in Granada. They focus on vegan capsules and often highlight “made in Spain” quality. Reviews mention that customers trust them for value-for-money and reliable customer service. Criticism: sometimes inconsistent stock availability and complaints about capsule size. Overall, strong brand image in the Spanish-speaking market.

Vegavero (Germany)
Vegavero is a German company with a clear “clean label” policy: vegan, non-GMO, no artificial additives. Many reviews highlight their eco-friendly packaging and transparency on sourcing. Customers often trust them for purity and tolerability of products. Downsides: higher price compared to Spanish local brands, and occasional reports of delayed delivery. Reputation: high in the vegan/eco-conscious community.

Vitaminalia (España)
Vitaminalia is another Spanish brand, with a strong focus on high-dose formulas and budget-friendly packs. They are often praised for cost efficiency (big bottles, good price per unit). Consumers say they are a “no-frills” brand — not much in terms of marketing polish, but reliable basics. Some reviews point out that tablets are large and not always easy to swallow. Still, Vitaminalia has become popular among people looking for straightforward supplements made in Spain.

Hivital (España)
Hivital is a younger Spanish company, positioning itself around high bioavailability and large supply bottles (often 6–8 months per pack). Reviews emphasize affordability and practical formulas with added cofactors (like B3 and B6). Negative notes include that they’re less internationally known, and packaging is sometimes considered “too generic.” Still, many users in Spain report positive experiences, especially on Amazon.
