GLP-1 Companion Supplements That Make Sense

Your supplements probably need to change if your appetite is down, your food volume is down and you're losing weight fast. Supplement stacks are typically designed for people eating normally. They are meant to be added to a healthy diet to enhance wellness. If you're on GLP-1s or are eating a restricted calorie diet then your physiology is different and your supplement routine should change too. In that case the supplements you choose should support the consequences of your reduced eating.

A lot of supplements are marketed towards people on a normal diet. So, when a person on GLP-1s is trying to lose fat, their supplements need to change too – they need to be modified for a person on a restricted diet, losing weight quickly, and trying to manage side effects. These GLP-1 companion supplements help manage the additional challenges of reduced nutrient intake while trying to lose weight quickly and can help with side effects that show up in places you wouldn't expect like your mouth.

What GLP-1 companion supplements are actually for



While some are touting supplements for GLP-1 users as a means to either

  1. Accelerate Weight Loss 
  2. Complement your Medication or
  3. Serve as a Wellness Aid 

Honestly, such supplements are merely intended to address the challenges associated with lowered Food Intake and subsequent reduced Nutrient Intake.

Instead of wondering what supplement a GLP-1 patient should take, it is better to ask the following question: When a person on GLP-1s is eating less, what are the functions that are harder to support? As stated previously, there are three categories of supplements that would be indicated for someone on GLP-1s who is eating less:

  • micronutrients,
  • supplements that support protein intake for preserving lean body mass, and
  • oral supplements for supporting the mouth through mouth and breath changes.

Surprisingly, few GLP-1 supplements are designed to address changes in the mouth as a result of reduced food intake. Because when you eat less, saliva production can drop and your mouth can become drier than usual, leading to a host of problems with your mouth and your breath. A generic multivitamin is not going to address these problems.

Why generic wellness formulas often miss the mark



A standard one-a-day is built for broad appeal. That usually means conservative dosing, crowded labels, and ingredients included because shoppers expect them, not because they fit a reduced-intake state.

A broad formula that is intended to be 'wellness' in nature contains a plethora of extras that are not likely to provide benefit when one is on a restricted calorie intake and are generally only added to the formula in order to make the label look better to the average consumer who has no idea as to what the various ingredients are for.

Next is muscle support. While it is true that additional protein in the form of a muscle supplement can help when appetite suppressed dieters maintain their lean mass during periods of rapid weight loss, this is not always easy to do. If one is feeling unwell due to their GLP-1 medication then the thought of downing a large amount of liquid to consume additional protein can be unappealing. Shaking up a large amount of protein powder with water to make a protein shake can be unappealing even when feeling 100% and thus supplements that support muscle in dieters on GLP-1s are best used by those who have determined that they cannot reliably take in sufficient amounts of protein from their foods to meet their needs. In such cases, supplements can be used to provide an extra boost of essential amino acids to support muscle maintenance. As with all supplements, there are many on the market that claim to support muscle in dieters on GLP-1s and thus it is up to each individual to do their own research and choose the supplement that best fits their individual needs.

The three supplement jobs that matter most



1. Micronutrient coverage for lower food intake



As the volume of your food intake decreases so does your potential for adequate nutrient exposure. Even the healthiest of reduced calorie diets will, from time to time, fail to provide the required amounts of certain nutrients. For this reason a targeted micronutrient formula can be a very valuable supplement for individuals on GLP-1s or on a reduced calorie diet for weight loss.

This does not mean megadosing everything. More is not automatically better. It means covering likely gaps with disclosed amounts that make sense for the context. Transparency matters here. If a label hides behind proprietary blends or vague claims, you cannot tell whether it is built for a real deficiency risk or just built to sound premium.

A good supplement to add to your weight loss arsenal is one that can be audited for quality. When a supplement has exact amounts of ingredients, in specific forms, and no mystery blends, then it can be a quality supplement for your diet.

2. Lean mass support during rapid loss



Weight loss is not necessarily equal to healthy weight loss. In order to preserve lean mass during weight loss, it is possible that supplements that support muscle can be helpful for individuals who are using GLP-1s or are following a very low calorie diet. However, these types of supplements are not meant to be a substitute for adequate amounts of protein and resistance training. They can, however, serve as an additional tool to help support muscle during times in which it is otherwise difficult to get enough high quality protein into one's diet to support muscle.

Amino acids can be useful in supporting lean mass when using GLP-1s for weight loss. This is particularly important as there is potential to lose significant amounts of muscle mass whilst losing fat mass. Amino acids will not replace resistance training or adequate intakes of protein from food but can be a useful supplement to consider for those experiencing difficulty in meeting their protein requirements due to reduced appetite or nausea and vomiting.

A couple of things to keep in mind though. This would be for people that are already trying to eat enough protein, but are struggling to consume enough protein on a day to day basis. There is no amount of supplements that can replace a well balanced diet with adequate protein, especially in the presence of regular resistance training. Also, as with everything, this is most useful for individuals that are engaging in rapid weight loss and therefore are in danger of losing significant amounts of muscle mass during the weight loss phase.

3. Oral support for mouth and breath changes



People talk about nausea and constipation. They talk less about the mouth. They should.

Reduced food intake can alter saliva production, mouth comfort and smell. This can cause dryness of mouth, a coated feeling in the mouth and bad breath. Unlike bad breath from the stomach that is usually masked with a mint, this kind of bad breath can be linked to an imbalance in the oral microbes. A simple oral probiotic may help with these kinds of oral changes and problems associated with eating less food.

The oral area may also change and cause problems, for instance dry mouth and less saliva. Some people may even experience unpleasant odor from their mouth. Such problems cannot be relieved by mint for instance. Therefore oral probiotics and other products that support the oral area specifically can be very useful additions to a GLP-1 companion stack.

How to evaluate GLP-1 companion supplements without getting sold



Vague promises on how a supplement does something are typical in this field of the dietary supplement industry because such promises are difficult to disprove by others. We on the other hand require more from a supplement!

Start with the label. If a product uses a proprietary blend then move on to the next product. If a product discloses the exact amounts of every ingredient then you can determine if the product is sensible. Also examine the rationale for each ingredient and form an opinion as to whether each ingredient has been incorporated to address a specific problem in the reduced food intake metabolic state.

Next up is the issue of manufacturing standards. This is often one of the weakest links in the world of nutritional supplements. It is all too easy to print out a clean label for a product but a lot harder to actually back it up with good manufacturing practices. In the end what you are looking for in terms of a good GLP-1 companion supplement is a disciplined approach to formulation that includes good sourcing and most importantly good quality control. If a brand's marketing speaks almost exclusively to your "lifestyle" as opposed to the specifics of the dosage of any active ingredients then there is a strong chance that said brand is not going to be able to deliver the goods.

So even when a supplement claims to be "backed by science" this doesn't necessarily mean that the product is a good fit for you. Instead it is more important to actually read the research behind a given ingredient and see if it makes sense for a person in a reduced food intake metabolic state who is worried about body composition or has issues with their oral health.

What a smart stack can look like



For many adults in active weight loss, the most rational approach is not a giant cabinet of supplements. It is a narrow stack with a job description.

To this end, many adults can be aided with a formula that contains a targeted mixture of micronutrients for those hard to get vitamins and minerals which are lacking during periods of reduced intake. An amino acid formula could also be very helpful for preserving lean body mass in cases where protein intake is inconsistent or not meeting required levels. Finally, an oral probiotic formula may help with mouth dryness, breath changes, and a coated feeling in the mouth while eating less.

More products do not equal more precision. A simple and effective supplement regimen is usually comprised of 3 targeted products, such as a micronutrient supplement, oral probiotics, and an amino acid supplement.

This is where FULM's approach comes from. The method builds for a person's metabolic situation, lists exact amounts of each component, and does not attempt to sell a general wellness product as if it were created for rapid weight loss. This is the standard that FULM works by.

What supplements cannot do



Supplements can support a constrained physiology. However, they cannot rescue a chaotic program.

A stack of supplements should complement a good plan of nutrition, not serve as a substitute for a diet that is not on track. Supplements can help to fill in nutritional gaps created by a reduction in intake but only if consumed consistently and in the correct amounts. As with any medication, there can be side effects and these can sometimes be severe. In such cases the prescribing clinician is the best person to help. A reduced diet may also require more individualized medical nutrition guidance than can be provided by a number of over the counter supplements.

Not to be confused with medication or treatment: good quality supplemental products are there to support a constrained body in terms of health, and to help it function better than it would without them.

The real standard: fit for purpose



The best GLP-1 companion supplements are NOT a bunch of fancy packaging or the most ingredients! The very best of these are support supplements made for the body during weight loss on a restricted diet! They are fit for their intended purpose!

That means covering probable nutrient gaps without filler. Supporting lean mass without pretending muscle maintenance is automatic. Addressing oral changes that many brands ignore because they are not glamorous enough for marketing copy. It also means respecting dose transparency, manufacturing quality, and the difference between a targeted formula and a generic multivitamin with a trendy headline.

Rapid weight loss is not just about losing weight, it affects many more aspects of your body than just your weight. Therefore your support products should reflect that as well. Many supplements were simply not designed for the specific metabolic state of rapid weight loss. So before purchasing a supplement ask yourself the simple question: what problem is this supplement going to solve for me.

That is the real question to be asking and will cut through a lot of the noise that is found on the web and in health food stores when it comes to the best GLP-1 companion supplements for rapid weight loss.
