Great Product

Great product! I have been taking square 1 since I originally saw gains in bulk at the Dallas Europa back in I believe 2015. I have seen the formula and labels change a few times but it has always been a great product at a great value. Love that the ingredients are from whole food and not fake lab made sources and I will continue to purchase this product as a staple because lets be real, if you are not eating 8+ servings of veggies and 5+ servings of fruits per day as an athlete/lifter then you are not getting enough micronutrients.

I’ve just started so can’t really say. But I was looking for a good vitamin and this looked like it would work. I’ve been impressed with all the other products of Gain in Bulk.

whole food vitamin & mineral
Square 1 uses whole food vitamins and patented organic minerals to guarantee your hard work creates the most results.

Start at square one and ensure that you have your body's basic needs met to get the most results out of your hard work.

Square 1 complete Vitamin and Mineral supplement for Bodybuilders
whole food vs. synthetic

Vitamins and minerals are essential to living a healthy lifestyle. A deficiency in just one essential vitamin or mineral can seriously alter your fitness progress. 

But, contrary to popular belief, not all vitamins and minerals are the same. Synthetic vitamins can damage your health and cause disease. Synthetic vitamin A can cause birth defects, liver damage, hair loss, weakness, anemia, joint pain and headaches. Synthetic vitamin D can cause kidney and cardiovascular damage, nausea, and irritability. Synthetic calcium can cause constipation and kidney stones. Synthetic vitamin B is linked to muscle weakness and severe loss of neuromotor coordination. Synthetic vitamin E is linked to toxic reactions and blocking of beneficial nutrients.

Square 1 contains 24 potent whole food vitamins and patented organic minerals. There are no synthetics present. Each dose contains 100% RDA of essential vitamins and minerals. The organic minerals are retained at the highest level and have the lowest toxicity of any mineral supplement in the world.

Square 1 Whole Food Vitamin and Mineral supplement testimonial
Hilary Shill

"Gains in Bulk Square 1 are easy to digest and absorb AND made with whole food vitamins and organic minerals. When I take these I feel AMAZING! I went without for a while and my body felt it. 😩

You work hard in the gym (when you’re not taking selfies, oh wait that’s me 😬) so you want to get maximum results, right? Missing just one vitamin or mineral can slow your progress. I LOVE Square 1 because it uses whole food vitamins and organic minerals so I know I’m putting the best in my body to get the most out of the hard work put in. Go grab some!"

Nutrition Supplement for Bodybuilders Testimonial
Nataile Eynon

"My supplements haven’t changed in pregnancy. I have done extensive research as well as gotten my doctor’s ok! ✅

I also want to say that Nutrition is the most important factor, but supplements can give you that extra edge as well as “supplement” (hence the word) nutrients that you might not be getting in your diet. The supplements I take provide muscle and strength benefits but also overall wellness for me and baby.

Square One- this is a multi vitamin but provides everything you need for a prenatal. Everything is whole food based, predigested with enzymes, and probiotics."
