Sports drinks can provide adequate sodium input for a few hours of exercise, but are insufficient over longer periods. Energy bars and gels are low in sodium and should be supplemented with electrolytes. SUCCEED! BUFFER/ELECTROLYTE CAPS provide electrolytes that are commonly found in blood plasma (sodium, potassium, chloride, bicarbonate, phosphate), in the proper proportions for hours of exercise. When taken with sufficient water, they help the body maintain good hydration status, which allows performance at a high level.

They also contain a chemical buffering system that neutralizes the acids formed during heavy exercise. Neutralization of excess acid will help performance and reduce the nausea associated with exercise in the heat. Maintenance of proper electrolyte levels will reduce swelling of hands and feet after many hours of exercise, and that will reduce "hot spots" and blisters on the feet. The buffers in S! Caps also help soothe the stomach. ...See more Succeed products.

Silverton Grocery

"This place is a gem! After our sub-par experience at a local pizza place we weren't sure what to expect of the grocery, and it far exceeded every expectation in terms of both selection, service and other customers - who were all lovely!"

"I was amazed to find organic options across the board (milk, cheese, yogurt - which were all on my list), fresh fruit and even a fair beer selection! When I forgot something while at the counter they smiled when I said I would be right back and the young guys who got held up by me seemed happy to wait. Amazing. They even commented on my re-usable grocery bag - which made me stick out like a sore thumb, but they thought it was cute and a good idea, so I'm going with it! If we're ever in Silverton, we'll be back."
