The subscription program offers refills every 2 weeks, 30 days, 45 days, 2 months, 3 months, or 4 months. This is important as protein may not be an everyday supplement need.

A subscription gives you a discount,free shipping, the option to receive your product anywhere from every one month to every six months, and the ability to adjust flavors with each order.

The sodium level is high, which works well for men who sweat a lot during training. But if your workouts stay light, this may feel like more sodium than you need. And electrolytes are definitely not going to be a daily need for most, so those 2-to-6 month subscription ranges are extra important here.

But for a steady pre-workout this subscription offers a reasonable cost. The product contains a reasonable 150 milligrams of caffeine per serving and no added sugar.

A subscription drops the price by 5 percent on the first order and 15 percent on future orders, and you can opt for deliveries every 1, 2, or 3 months. This is great for men who vary their training loads and may not be taking pre-workout every single day.

Fitness and Commerce Editor Charles Thorp, NASM did feel the benefit of better sleep and improved cognitive function when he started taking during the day. But as cautioned by the brand, there is a little drowsiness during the first few days of use.

Thorne’s Complete Biotic deliver to our gut pre-, pro-, and postbiotics (a combination of good bacteria and the food that fuels it) each week of the month. Instead of just one strain, this provides a variety—and early research suggests that a multi-strain opinion may support a more balanced microbiome.

The blend includes probiotics and prebiotics in individual packets of orange-flavored powder. Powder tends to absorb better than capsules, and the individual packets are easy to travel with. Thorp noticed better digestion when he used them on a recent trip (travel regularly plays havoc with the system).

You can save up to 20 percent by opting for a subscription. You can choose your refills to arrive every two weeks, 2 weeks, 30 days, 45 days, 2 months, 3 months, or 4 months. And though the price sits higher than basic probiotics, the multi-strain approach is a better approach worth trying if you have a testy digestive tract that hasn’t benefited from basic probiotics.

Cymbiotika takes a plant-based approach to omega-3s by using algae oil instead of fish oil. That shift lowers concern about heavy metals and oxidation, and it removes the fishy aftertaste—a huge downside to many omega-3 supplements. The blend features DHA, EPA, astaxanthin, sea buckthorn oil, and evening primrose oil—ingredients that support heart health, joint comfort, and steady cognitive function.

The liquid format absorbs better than capsule omegas, and the pump-top bottle makes dosing simple—you can take it straight from a spoon or mix it into a smoothie. The citrus-berry flavor is a bit strong but honestly, I’ll take anything over a fishy fish oil.

Subscribers save around 10% and can pause or skip any delivery, which comes every 30 days. A small downside though is that there are no options outside of that 30-day subscription range, you’ll have to use the pause or skip if you need flexibility. But for men who want a clean omega-3 source without the taste or texture of fish oil, this formula fits naturally into a daily routine.

Though you do get vitamin D from food sources like fatty fish and egg yolks, vitamin D levels tend to dwindle in the winter months as your skin makes vitamin D when it’s exposed to sunlight. Transparent Labs pairs vitamin D3 with vitamin K2 to support bone health, immune function, and calcium balance. The subscription saves about 10 percent and comes in either 15-, 30-, or 45-day cycles. The downside here though is that the bottle comes with 60 softgels with one dose being one softgel, so you’ll likely need to skip deliveries on your account to avoid excess product gathering in your pantry.

Vitamin D works best with steady use, so a predictable refill helps maintain healthy levels through the year. If you feel low on energy, get your vitamin D levels tested first, and if your physician recommends a supplement, Transparent Labs is one of our favorites.
