What Customers Are Saying
Based on 2 reviews
Been taking this for about 6 weeks now and honestly really impressed with the results. My doctor suggested I try magnesium for the muscle cramps I was getting after workouts, and this Windmill brand has been fantastic. The 400mg dose seems to be the sweet spot - I take one with dinner and I've noticed way less muscle tension and better sleep quality. For under $10, you really can't beat the value compared to some of the pricier brands at the health food store. Shipping was super fast too, got it in like 2 days. Will definitely be reordering this one!
Excellent supplement! I switched to this from another brand that was costing me almost $20 for the same dosage. The tablets are easy to swallow and I haven't had any stomach upset like I did with my previous magnesium. I've been using it as part of my morning routine for muscle and nerve support, and I can definitely tell the difference in how relaxed my muscles feel throughout the day. Great quality at an unbeatable price point.
