Magnesium drinks compared: TRIP, OHMG and Liquid RELAX
Which magnesium drink is best?
Magnesium drinks are sparkling cans with added magnesium, and the honest difference is dose plus what else is in the can. TRIP's calm can carries 120mg of magnesium with a small amount of Lion's Mane. OHMG magnesium water carries 100mg per 330ml can with nothing else added. Grass & Co. Liquid RELAX carries 70.5mg of magnesium per 250ml can, plus 1,000mg Reishi extract and Ashwagandha KSM-66. If you want the most magnesium per can, TRIP wins. If you want magnesium and nothing else, OHMG is the cleanest. If you want magnesium alongside a mushroom-and-adaptogen blend with an alcohol-free evening ritual, that is the Liquid RELAX pitch.

The trade-offs
Grass & Co. Liquid RELAX (70.5mg)
- Only one of the three with a mushroom extract — 1,000mg Reishi plus Ashwagandha KSM-66
- Carries the widest approved-claim set (magnesium, B6, B12)
- Built as an alcohol-free evening ritual, peach and chamomile
- Lowest magnesium dose of the three cans
- More expensive per can than magnesium water
TRIP calm can (120mg)
- Highest magnesium per can
- Pleasant, widely available
- Small mushroom dose is not stated per can
- Fewer supporting actives
OHMG magnesium water (100mg)
- Zero calories, zero sugar, nothing added but magnesium
- Three forms of magnesium (citrate, glycinate, malate)
- Cheapest way to drink your magnesium
- No botanicals or mushrooms — it is magnesium water
- Lower dose than TRIP
If you are choosing a magnesium drink purely on dose, TRIP's 120mg wins and OHMG is the cleanest zero-everything option. Liquid RELAX is the pick when you want the magnesium to come with a full evening formula — 1,000mg Reishi extract, Ashwagandha KSM-66 and B vitamins — because magnesium drinks and mushroom drinks are solving the same evening problem from different directions.
On magnesium alone, we lose: Liquid RELAX has 70.5mg per can against TRIP's 120mg and OHMG's 100mg, and a dedicated magnesium supplement beats every drink on dose per pound. Our case is the mushroom-and-adaptogen blend around the magnesium, not the magnesium itself.
