We lost 107 lbs!

 What is calotren?

Calotren is a specially formulated, scientifically proven Collagen Protein/Digestive Enzyme complex that aids the body in repair and rebuilding of lean muscle with the industry's highest standard of quality ingredients. This scientific complex with patented ingredients helps your body absorb the ingredients up to 3 times higher than competitorsNumerous in vitro studies plus two separate human clinical studies have shown the superior ability of ingredients in Calotren to quickly break down protein, increase available amino acids in the blood, decrease C-reactive protein levels and decrease the large peptides associated with stomach discomfort that results from consuming protein. Click HERE for those clinical trials.   This results in higher metabolism, weight loss and side benefits that include: improved joint flexibility and less joint pain, better sleep, more natural energy, and better digestion. 

It is not a drug.  It is not a stimulant.  It is not a quick fix.  It is not a fad.  Calotren has had proven lasting results for over 20 years.

Calotren Capsules: Collagen Hydrolysate (Bovine Source), ProHydrolase (patented digestive enzyme complex)

Other Ingredients (Capsule): Gelatin, Vegetable Magnesium Stearate, and Aloe Vera Leaf (200:1 Extract). Calotren Advanced Capsules contain an exclusive digestive enzyme combination to maximize your benefits. Calotren is also available in liquid.

Calotren Liquid: Filtered Water, Collagen Hydrolysate (Gelatin Peptone), Aloe Vera, Vegetable Glycerin, Natural and Artificial Raspberry Flavor, Potassium Sorbate, Citric Acid and Sodium Benzoate.

Calotren is not intended to replace proper diet and exercise. Calorie reduction and physical activity will enhance any weight loss plan. Do not use Calotren as a meal replacement; it contains no vitamins or minerals needed by the body. These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure or prevent any disease.


Suggested UseTake four (4) Calotren Capsules at bedtime on an empty stomach (2-3 hours after your last meal) with 4-8 oz of water. If you forget or are unable to take at bedtime, take it first thing in the morning. 

Yes, you take Calotren at bedtime and then go right to sleep. 

Within the first 90 minutes of sleep, your body goes through rejuvenation, repair, and growth. Calotren works with your body's natural repair and regrowth stage, helping to support and strengthen lean muscle tissue. Strong lean muscle then assists the body in burning fats and sugars more effectively, resulting in weight loss. The high-quality collagen protein in Calotren is also frequently utilized by the body for better sleep and joint repair.

Calotren works best if you can take it right at bedtime by itself so your body can utilize it most efficiently during the first phase of restorative sleep.



How fast will I see results? It does take time and Calotren is not a "quick fix." Our PROVEN 90 day supply is where our huge 86% success rate begins. While some people do see results quickly, inch loss and pound loss is expected within 4-6 weeks of taking Calotren.  Doctors suggest 1-2 pounds of weight loss per week is safe, maintainable weight loss.*
What if I don't like it or don't see results?  Most people love it.  In fact, our return rate is less than 1%, BUT, if for whatever reason you don't, we will take care of you and do you "right." Your team of support that comes with every purchase will do all they can to help you reach your weight loss goals so you will SEE and/or FEEL results within 4-6 weeks. If you are uncertain, your personal Calotren consultant will be available to do all he/she can to help you jump-start the weight loss.  If that doesn't help, we have an awesome 45 day money back guarantee and a flexible return policy. 

What if I forget to take it? You can take it first thing the next morning and then wait 30-45 minutes to eat or drink anything.  Resume same dosage that night.  (taking it twice a day is even recommended in some cases) 

What if I can't take it at bedtime? If you cannot consistently take Calotren at bedtime, you can consistently take it first thing in the morning instead.  Wait 30-45 minutes to eat or drink anything.  It may take a little longer to see weight loss results, but we have had lots of customers throughout the years who have had success taking it this way. 

Will it keep me up at night?  No. In fact, there is science to support what so many customers tell us which is that it helps you sleep more soundly.  Some customers even report "dreaming" again which happens during the deepest stage of the sleep cycle.

I have lost 82 pounds in the last year! Calotren has changed my life completely. I used to weigh 242 pounds and I am down to 160. My goal is 135 pounds. I use to be a size 20+ and am on my way to my goal of a size 8. I have tried other diets and have lost weight but have always put it back on, or have spent tons of money on things that don't work. Calotren is the real thing and the results are awesome! I use to cry when I'd see myself in pictures and now I am loving it more and more. Thank you for making such an awesome product.

I've been with Calotren since 2012 and I went from 298 lbs to 142 lbs. I've tried several products and this is the only one that has worked. I continue to take it to maintain my weight and help with my joints. I have had several people try Calotren because of my significant weight loss. I love this product.

I got Calotren and I tried it and was amazed at how well it worked. I lost my stomach. I got into pants that I had not been into in a year and a half. I had exercised and nothing made a difference, but Calotren really worked. It's been wonderful!

I've been trying to reach my goal of 135 lbs... I've lost 27 so far. I had high blood pressure, but my blood pressure is good now. I have more energy. Also, no more restless legs at night. I love this product. I have been a long time customer; wouldn't take anything else.

I sleep so much better! I wake up at 4 a.m. ready to start my day instead of sleeping until noon. I just FEEL better. My ol'man and I are both doing this together and he came home yesterday and said his wedding ring keeps falling off. I told him mine did, too. That's pretty funny to us. He's a retired military man and when he hits 220 lbs, he gets mad at himself. His back hurts and he feels sluggish. Now he feels energetic and frisky again. THANK YOU CALOTREN!!
