Nutritional Support While Using GLP-1 Medications Like Semaglutide: What to Consider About Vitamins and Supplements

Why Consider Vitamins with Semaglutide?

GLP-1 medications like semaglutide are designed to help regulate appetite and support metabolic health by mimicking hormones that impact digestion. As a result, some people experience reduced hunger, smaller portion sizes, or less frequent meals.

These changes in eating patterns may lead to lower intake of essential nutrients over time. Additionally, slower digestion associated with GLP-1 medications may affect how certain vitamins, like B12, are absorbed in the body.

Because of these shifts, some individuals explore vitamins or supplements as a way to help maintain nutritional balance. However, the need for supplementation varies widely and should always be based on a licensed healthcare provider’s assessment of your lab results, diet, and symptoms.

Eden connects you with licensed healthcare providers who can help evaluate whether supplements such as vitamin B12, vitamin D, multivitamins, or others might be appropriate for your wellness goals. These licensed healthcare providers take a personalized approach to care, ensuring that any recommendations are safe, evidence-informed, and aligned with your overall health plan.

Commonly Considered Supplements While Using GLP-1 Medications

As your appetite and digestion adjust with GLP-1 medications like semaglutide, your daily nutrient intake may also change. Some individuals consider supplements to help support nutritional balance during this time, particularly if their diet becomes more limited.

Below are some supplements people may explore in conversation with a licensed healthcare provider. The need for supplementation should always be guided by lab testing, dietary habits, and clinical evaluation.

1. Vitamin B12

Some individuals may experience changes in how their body absorbs vitamin B12 due to slower digestion or reduced food intake while using GLP-1 medications. B12 is typically obtained through food sources like meat and dairy, and absorption can be influenced by digestive function.

A licensed provider may recommend sublingual or injectable B12 if lab testing indicates low levels or if symptoms such as fatigue are present. The appropriate form and dosage can vary depending on individual health needs.

2. Vitamin D

Vitamin D levels are commonly assessed through bloodwork and may be lower in individuals who have limited sun exposure or higher body weight. Because vitamin D is essential to many metabolic processes, a provider may suggest supplementation if your levels are below optimal.

The form (D2 vs. D3), dosage, and duration of vitamin D use should be personalized and monitored by a licensed healthcare provider.

3. Multivitamins

If GLP-1 therapy results in reduced calorie intake or dietary variety, a multivitamin may help fill nutritional gaps. Multivitamins may provide a range of micronutrients, including iron, zinc, and selenium, but not all formulations are the same.

A licensed provider can help you choose a high-quality multivitamin and ensure it doesn't overlap with other supplements or prescriptions you're taking.

4. Omega-3 Fatty Acids

Some individuals explore omega-3 supplements, such as fish oil or algae-based EPA/DHA, as part of their wellness routine, especially during dietary changes. These fatty acids are typically found in fish and play a general role in health and wellness.

If you are not consuming fish regularly, a licensed healthcare provider may help you determine if an omega-3 supplement could support your overall nutritional intake.

5. Probiotics

GLP-1 medications may impact how food moves through your digestive system. Some people consider probiotics to support regularity or comfort during these changes.

Probiotic supplements vary widely in strains and potency, so it’s important to consult a provider to identify options that may suit your needs and lifestyle.

Supplements should not be started or adjusted without speaking to a licensed healthcare provider. While they may support nutrition, they are not a replacement for medical care or a balanced diet. Eden makes it easier to connect with providers who can guide these decisions based on your personal health profile.

Supplement Timing and Quality Tips

When it comes to vitamins and supplements, timing and quality may influence how your body responds, especially when you're also using GLP-1 medications like semaglutide.

While individual needs will vary, here are some general considerations to discuss with a licensed healthcare provider:

Timing Supplements Around GLP-1 Use

Some people may choose to space out their supplements and GLP-1 medication by 1–2 hours, which may help minimize the chance of digestive overlap. This may be especially helpful with oral supplements that rely on stomach absorption. Sublingual or injectable forms, like some types of B12, may not require this consideration.

Your provider can help create a supplement schedule based on your routine, digestive response, and overall goals.

Taking Supplements with or Without Food

Fat-soluble vitamins (such as vitamins D, A, E, and K) are often best absorbed when taken with a meal that contains some dietary fat. Water-soluble vitamins like B12 or vitamin C can typically be taken on an empty stomach, although individual tolerance varies.

Your licensed healthcare provider can advise on the best time and conditions for each supplement based on its form and your digestion when appropriate.

How to Choose High-Quality Supplements

Not all supplements are created equal. Look for third-party certifications from organizations like:

• USP (U.S. Pharmacopeia)
• NSF International
• ConsumerLab

These certifications help ensure that the product contains what the label says — and is tested for purity, potency, and quality.

Avoid supplements with excessive additives, overlapping nutrients, or doses that far exceed daily recommendations, unless specifically advised by a healthcare provider.

Watch for Changes and Check In

If you notice any new or unusual symptoms after starting a supplement, including digestive changes, fatigue, or discomfort, reach out to your healthcare provider. Supplements can sometimes interact with other medications or produce side effects, even when they’re available over the counter.

The licensed healthcare providers available through the Eden platform can help monitor your supplement plan and adjust it as needed.

Considering B12 Supplementation While Using Semaglutide 

Some individuals using GLP-1 medications like semaglutide may explore vitamin B12 supplementation, particularly if they experience changes in appetite or digestion that could impact overall nutrient intake.

Because vitamin B12 is primarily absorbed in the stomach and small intestine, slower digestion and reduced dietary variety may influence how much your body gets from food alone. A licensed provider may recommend checking your B12 levels through a simple blood test if symptoms like low energy or fatigue are present, or if your diet has become more restricted.

B12 Supplement Options

If supplementation is needed, your provider may suggest:

• Oral B12, commonly in tablet or capsule form
• Sublingual B12, which dissolves under the tongue and bypasses digestion
• Injectable B12, which may be used for individuals with absorption concerns

The right form and dose depend on your specific health needs and provider guidance.

What About MIC B12 Blends?

You may see MIC B12 blends marketed as part of wellness or metabolic support programs. These formulas typically include:

• Methionine
• Inositol
• Choline

While these blends are popular in some wellness communities, the evidence supporting their effectiveness is limited and not well-established in clinical research. A licensed healthcare provider can help you determine if these supplements are appropriate for your goals or if a standard B12 option may be more suitable.
