Absolutely, but you'll have to watch your diet a lot more than if you were at 400-600. You'll still get a bit warm at night, but nothing like a high dose. And you'll still start sweating if you drink soft drinks or eat sugars.
And PLEASE make sure you're adding a strong antioxidant blend. The stuff I use has about 5-6 really good antioxidants added right into the capsule.
