You're Eating Less on GLP-1. Your Body Still Needs Every Nutrient.

You've been doing everything right. You're losing weight. You're following the protocol. So why are you dragging yourself through the day?

On GLP-1, you might eat 1,200-1,600 calories on your most suppressed days. At those levels, hitting your recommended daily intake of B12, B6, folate, magnesium, and iron through food alone is clinically impossible. These are the exact nutrients that keep your mitochondria running and your energy production online.

When they drop, you feel it. Not as a vague tiredness, but as that specific, heavy fatigue that sleep doesn't fix and caffeine barely touches.

Bio-Avail Multi delivers methylated B12 (methylcobalamin) and methylated folate (L-5-MTHF as Quatrefolic®), the active, immediately usable forms that require no conversion in a gut that's already working differently on GLP-1.

Most multivitamins use cyanocobalamin and folic acid, cheap synthetic forms that require your body to convert them before use. When digestion is slower and absorption is altered, that conversion step matters.

Within the first one to two weeks, many people notice their energy shifting, not a jolt, but the quiet return of a baseline that felt like it had been gone for months.

"I started Bio-Avail Multi two weeks into Wegovy. The fatigue that I thought was just 'how dieting feels' started lifting by week three. I hadn't realized how depleted I was." — Maria T.

Telogen effluvium, the clinical term for the sudden, alarming hair shedding many GLP-1 users experience, is one of the most emotionally distressing side effects nobody warned you about.

It's not from the medication directly. It's from what the medication does to your nutrient levels.

Hair follicles are among the most metabolically active tissues in your body. They're also among the first to go quiet when resources run short. Rapid caloric restriction drops iron, zinc, and biotin, the three nutrients most directly linked to hair growth cycles, often within the first two to three months of GLP-1 therapy.

Your body makes a triage decision: redirect limited nutrients toward essential organs. Hair can wait.

Bio-Avail Multi provides therapeutic doses of zinc (15 mg as Albion® bisglycinate chelate, the most absorbable form), biotin (300 mcg), and a full iron-supporting nutrient profile. These are delivered in forms your gut can actually absorb even when digestion is slower than usual.

Hair shedding typically begins two to three months into GLP-1 therapy and peaks around month four to six. Starting nutritional support early matters. The goal is to keep your follicles resourced enough that they don't have to choose.

"My hairstylist noticed before I did. Three months after starting Bio-Avail Multi alongside my Mounjaro, she said, 'Something changed. You have a lot of new growth coming in.' That's when I realized the shedding had actually stopped." — Christine L.

You're already managing a GLP-1 medication, meal planning around reduced appetite, and paying attention to protein and fiber. The last thing you need is a complicated supplement regimen on top of it.

Most people on GLP-1 therapy piece together their nutritional support: a B-complex here, a vitamin D there, a magnesium glycinate before bed, maybe an iron supplement if their doctor flagged it. Four bottles. Four different schedules. No guarantee the forms are absorbable or the doses are meaningful. Bio-Avail Multi was designed to replace all of it.

Four capsules daily (two with breakfast, two with dinner) deliver:

- Methylated B vitamins (B12, folate, B6, riboflavin) in their active forms

- 3,000 IU vitamin D3 for immune, bone, and metabolic support Highly absorbable magnesium as Albion® bisglycinate chelate, not the cheap oxide form that causes GI distress

- Zinc, copper, selenium, manganese, and chromium as chelated minerals

- A full-spectrum vitamin K blend with K1, MK-4, and MK-7

- 11 phytonutrients including quercetin, resveratrol, lutein, blueberry, and elderberry

- Betaine HCl to support gastric acid production, critical when GLP-1 slows digestion

No redundancy. No gaps. No four separate bottles.

"I was taking five different supplements before I found this. Now it's two capsules twice a day and I feel better covered than I ever did with the pile." — Derek M.

Not all multivitamins are created equal. The form of each nutrient matters, especially when you're on a medication that alters how your gut processes food and absorbs what comes through.

GLP-1 medications slow gastric emptying. That changes the absorption environment for several key nutrients:

- Vitamin B12 requires gastric acid to cleave from food protein before absorption. Slowed digestion reduces this window. Bio-Avail Multi delivers methylcobalamin, the form that doesn't depend on that conversion.

- Fat-soluble vitamins (D3, K, E, A) require dietary fat in the same meal to absorb. When appetite suppression leads to erratic eating and small meals, this window becomes unreliable. Bio-Avail Multi's split-dose design is built around this.

- Magnesium oxide, found in most grocery store multis, causes GI distress and absorbs poorly. On a GLP-1, that's the last thing your gut needs. Bio-Avail Multi uses Albion® bisglycinate chelate, gentle on digestion and well-absorbed.

- Folate as folic acid requires enzyme conversion that a significant portion of the population can't complete efficiently. Bio-Avail Multi uses Quatrefolic® (L-5-MTHF), the pre-converted, immediately active form.

The American Journal of Clinical Nutrition joint advisory from four major medical societies flagged GLP-1-associated nutrient depletion as a critical unmet need in therapy management. Most prescribers aren't addressing it. This formula was designed specifically to.

"My doctor hadn't mentioned anything about nutrient depletion. When I brought up my fatigue at my next appointment, she ran labs and found I was low in B12, D, and magnesium. She asked what I was taking and said Bio-Avail Multi was exactly the right approach." — Sandra K.

Standard multivitamins were designed to hit minimum daily values on paper. They weren't designed for someone eating 30-40% fewer calories than usual, with altered digestion, who needs every nutrient to actually arrive.

Bio-Avail Multi goes further than preventing deficiency. It was formulated to support optimal function, which matters more on GLP-1 than almost any other context.

Beyond the core vitamins and minerals, it delivers:

- Betaine HCl (200 mg) to support stomach acid production. Healthy gastric acid is essential for protein digestion, B12 absorption, and mineral ionization. Slowed digestion on GLP-1 can compromise this.

- Choline (450 mg as betaine HCl and trimethylglycine) for liver function, brain health, and metabolic support. Most people are chronically low in choline regardless of diet, and GLP-1 doesn't improve that.

- 11 phytonutrients including quercetin, resveratrol, lutein, lycopene, elderberry, and broccoli sprout extract for antioxidant defense and cellular protection. Rapid metabolic change during weight loss creates oxidative stress your body needs help managing.

This isn't a "cover the bases" multi. It's formulated to support the physiological demands of the body during active GLP-1 therapy, including the cellular-level changes happening during rapid weight loss.

"I've taken a lot of multivitamins over the years. This is the first one where I actually noticed a difference. Mental clarity, energy, and my nails are growing faster than they have in years. I didn't expect all of that from a multi." — Joanna R.

When GLP-1 medications started becoming widely used, I started paying close attention to what the research was showing about nutritional consequences.

The data was clear: eating 30-40% fewer calories means getting 30-40% fewer micronutrients. And the altered digestion GLP-1 creates compounds that problem. Most people on these medications are becoming depleted in the exact nutrients that keep them feeling well, thinking clearly, and maintaining the lean mass and healthy aging that make the weight loss meaningful in the first place.

Most doctors prescribing GLP-1 medications weren't addressing this. Most multivitamins on the market weren't designed for it.

Bio-Avail Multi was originally formulated as a foundation-level nutritional supplement based on 15 years of clinical practice. What's become clear is that it's also exactly what GLP-1 users need: bioavailable forms, therapeutic doses, and comprehensive coverage for a body that's eating less but still requiring everything.

If you're on a GLP-1 medication and not supplementing with a high-quality multi, you're likely depleted in ways you can feel but haven't fully identified yet.

This is the version that works.
