Supplements can make a huge impact, but you have to give them time.

Supplements aren’t instant. Here’s how long they may actually take.

Magnesium: 3–7 days for muscles, can take up to 3 months for some mental health challenges.
Vitamin D: 4–8 weeks
Omega-3s: 4–12 weeks
B vitamins: Can be instant, but within days for many people

Timeline = consistency + the right dose + the right form.
