While local Spanish pharmacies carry various magnesium supplements, they often lack the high-purity formulations found in the US. Momentous has become the gold standard, often recommended by top performance experts. However, finding it on a shelf in Madrid or Barcelona is still a challenge, leading many to search for smarter ways to source it.

Why Biohackers in Spain are Looking West

The biohacking community in Spain is growing rapidly, but the market hasn't quite caught up. Many enthusiasts find that local alternatives don't offer the same level of transparency as US brands. Momentous, in particular, has built a reputation for third-party testing that ensures you are getting exactly what is on the label. This trust factor is why many choose to buy from US ship to Spain rather than settling for what is available locally.

Furthermore, the price difference in 2026 is impossible to ignore. Even with shipping costs, the total investment for a multi-month supply often beats the inflated prices of boutique health shops in Europe.

When you factor in the lower US retail price and the lack of sales tax at the point of origin, the savings are substantial.
