The Science

Collagen protein is the essential active ingredient in Calotren.

While collagen protein provides many benefits, its role in promoting healthy lean muscle and weight loss has been known for over 30 years.

Collagen is the second most abundant substance in the body-behind water-and is equally important for all bodily functions. Unfortunately, studies have shown that after the age of 30, collagen production could decrease by 1% a year, so by age 50, the body could lose 20% of its capacity to produce collagen. This drastically decreased level of collagen results in a slower metabolism and weight gain, as well as other issues like joint pain. However, taking a supplemental dosage of a high-quality collagen protein such as Calotren® can help build healthier lean muscle, which boosts the body's metabolism naturally and promotes weight loss, as well as other side benefits.

Collagen protein also performs many other important functions in the body.

How Calotren® Works

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.

How to Take Calotren®

INSTRUCTIONS: Take 4 Calotren® capsules or one tablespoon of Calotren® liquid with a glass of water at bedtime.

Do not eat or drink anything except water or water with lemon at least 2-3 hours prior to taking Calotren®. Putting 2-3 hours between your last meal and bedtime allows the Calotren® to be more readily absorbed and to work more effectively. If you have a late night, forget, or are unable to take the Calotren®, you may take it the next day 30-45 minutes prior to breakfast on an empty stomach. Then resume your nightly regimen that same day. We do, however, recommend taking it at night if at all possible for best results. Calotren®may also be taken 30-45 minutes prior to exercise to assist with increased energy and stamina.

As with any weight loss supplement, we recommend exercise and portion control to accelerate your results. Eat a balanced diet with sensible portions during the day, and take your Calotren® at bedtime.

How long should I take Calotren®?

Most people begin seeing inch loss and/or weight loss within the first few weeks after starting Calotren®.

However, since Calotren® assists your body in losing weight naturally - without drugs or stimulants - the initial onset of benefits can vary from person to person. If you have joint pain or injuries, your body may utilize the collagen protein there first. We therefore recommend beginning with a 90-day supply of Calotren®to ensure optimum results. Because Calotren® is a supplement that is GOOD for you, you can safely take Calotren® as long as necessary or desired.
