WrenLife GLP-1 Support Multi+: Daily Nutritional Support When Appetite Is Reduced

Medications that target incretin pathways—including semaglutide, a GLP-1 receptor agonist, and tirzepatide, a dual GIP/GLP-1 receptor agonist—can reduce appetite and calorie intake and can delay gastric emptying. For many people, these effects support meaningful weight reduction. They can also make it harder to eat enough variety or nutrient-dense food, especially when nausea, vomiting, constipation, or early fullness are present.^1–3

Current expert guidance emphasizes a nutrient-dense eating pattern, adequate hydration and protein, resistance exercise, management of gastrointestinal symptoms, and supplements tailored to individual needs.¹ Importantly, the evidence does not show that every person using a GLP-1–based medication develops a vitamin or mineral deficiency. A 2026 systematic review found that only 2 of 41 randomized trials of liraglutide, semaglutide, or tirzepatide assessed or reported changes in dietary intake, highlighting how much remains unknown.⁴

Reduced Intake Is the Main Nutritional Concern—not Proven Broad Malabsorption

Semaglutide and tirzepatide can delay gastric emptying, and their prescribing information notes that this may affect the absorption of some oral medications.^2,3 That is not the same as showing broad malabsorption of vitamins and minerals. In clinical pharmacology studies, injectable semaglutide did not meaningfully change exposure to the oral medications that were evaluated.²

For most people, the more established concern is straightforward: when total food intake and dietary variety decrease, intake of some nutrients may also decrease. Individual risk depends on baseline diet, the amount and rate of weight loss, gastrointestinal symptoms, other medications, prior bariatric surgery, medical conditions, and laboratory results.

Where WrenLife GLP-1 Support Multi+ Fits

WrenLife GLP-1 Support Multi+ is a two-tablet daily multivitamin and mineral supplement designed to complement dietary intake when someone is eating less. It is not a weight-loss product, a treatment for medication side effects, or a replacement for a balanced diet or individualized medical care. The finished Multi+ formula has not itself been evaluated in a clinical trial.

What Each Two-Tablet Serving Provides

• Vitamins: vitamins A, C, D3, and E, plus thiamin, riboflavin, niacin, vitamin B6 as pyridoxal-5′-phosphate, folate as calcium L-5-methyltetrahydrofolate, vitamin B12 as methylcobalamin, biotin, and pantothenic acid.
• Minerals: calcium, phosphorus, zinc, selenium, chromium, molybdenum, and sodium.
• Specialty ingredients: Ginfort® ginger root extract (200 mg), methylsulfonylmethane or MSM (500 mg), hyaluronic acid as sodium hyaluronate (120 mg), and grape seed extract (150 mg).

The Supplement Facts panel lists 19 vitamins and minerals. Sixteen provide at least 100% of the Daily Value. Calcium provides 220 mg (17% DV), phosphorus provides 110 mg (9% DV), and sodium provides 10 mg (less than 1% DV). Multi+ does not contain iron or magnesium.

Foundational Vitamin and Mineral Support

The B vitamins in Multi+ support normal energy metabolism, while vitamin B12 supports normal red blood cell formation and nervous-system function.* Vitamin D3, calcium, and phosphorus support normal bone health.* Vitamins A, C, and E, along with zinc and selenium, support normal immune, antioxidant, and tissue functions.*

These are normal structure-and-function roles of the nutrients. They should not be interpreted to mean that taking more than the Daily Value will increase energy, prevent illness, or correct a deficiency that has not been diagnosed.

Hair, Skin, and Nails: Support, Not a Hair-Loss Treatment

Multi+ includes biotin, zinc, selenium, vitamins A, C, and E, MSM, hyaluronic acid, and grape seed extract as part of its hair, skin, and nail support profile.* However, Multi+ has not been shown to prevent or treat hair loss associated with rapid weight reduction or medication use.

Biotin deficiency can cause hair and nail changes, but true deficiency is uncommon, and the National Institutes of Health notes that evidence supporting high-dose biotin for hair, skin, or nails in otherwise healthy people is limited.⁵ Persistent or significant hair shedding deserves a clinical evaluation because protein intake, iron status, thyroid function, illness, stress, and the rate of weight loss may all matter.

Multi+ also provides 120 mg of hyaluronic acid. Randomized trials have studied oral sodium hyaluronate at this daily dose for skin hydration and other skin measures, but results apply to the specific ingredient forms tested and do not establish that the complete Multi+ formula will produce the same outcomes.⁶

Ginger and Digestive Comfort

Each serving contains 200 mg of Ginfort® ginger root extract. Ginger has been studied in several digestive settings, but studies involving pregnancy, postoperative nausea, chemotherapy, or functional dyspepsia do not prove that this product relieves gastrointestinal side effects caused by semaglutide or tirzepatide. Persistent vomiting, inability to maintain fluids, severe abdominal pain, or worsening gastrointestinal symptoms should be discussed promptly with the prescribing clinician.

What a Multivitamin Cannot Replace

A multivitamin does not provide enough protein, fiber, fluid, or calories to replace food. It also cannot replace resistance exercise, which is emphasized alongside adequate protein intake to help preserve muscle during weight reduction.¹ A food-first plan built around protein-rich foods, vegetables and fruit, whole grains or legumes as tolerated, and adequate fluids remains the foundation.

Because Multi+ is iron-free and magnesium-free, anyone who needs either nutrient should discuss food sources, laboratory testing, and an individualized supplement with a healthcare professional. Iron should not be added automatically solely because someone is using a GLP-1–based medication.

How to Take Multi+ Safely

• Take two tablets daily with a meal, or as directed by your healthcare provider.
• Do not combine Multi+ with another full multivitamin or prenatal unless your clinician has reviewed the combined totals.
• Tell your prescriber about every supplement and medication you use.
• If you are pregnant, breastfeeding, or trying to conceive, ask your clinician which prenatal or other supplement is appropriate. Multi+ is not formulated as a prenatal.

Biotin and laboratory tests: Multi+ contains 3,000 mcg of biotin (10,000% DV). Supplemental biotin can interfere with certain laboratory tests and can produce falsely high or falsely low results. Tell your clinician and laboratory personnel that you take biotin before bloodwork, and follow their instructions about whether and when to pause it.^5,7

The Bottom Line

Reduced appetite can make consistent nutrition more challenging during GLP-1–based treatment. WrenLife GLP-1 Support Multi+ offers a convenient way to supplement intake of the vitamins, minerals, and specialty ingredients listed on its label.* It works best as one part of a broader plan that includes nutrient-dense food, adequate protein and fluids, resistance exercise, and individualized medical follow-up.
