What Health Benefits May I Expect?
For those managing chronic conditions, electrolyte supplements are often one of the first things a care team recommends.
  • Reduced inflammation through balanced electrolytes that don't spike blood sugar

  • Enhanced medication absorption with proper cellular hydration

  • Fatigue management from 87 trace minerals supporting energy production

  • Normal immune support from selenium, zinc, and other protective minerals

  • Digestive comfort with gentle, liquid minerals that don't irritate sensitive systems

  • Autonomic regulation supporting those with POTS, dysautonomia, and blood pressure issues

  • Reduced brain fog through optimal mineral balance for nerve function

  • Joint and muscle support from natural anti-inflammatory minerals

  • Clinically-proven hydration that maintains a 10x more positive net fluid balance than water alone
What Ingredients Does Buoy Avoid?
Buoy uses only wild-harvested, whole-food ingredients and does not add anything for taste or texture.
  • No Sugar, Sweeteners, Flavors: Sugar feeds inflammation and disrupts already-sensitive blood glucose levels. Sweeteners can trigger digestive issues, headaches, and kidney inflammation.

  • No Unnecessary Additives: Every unnecessary ingredient is another potential trigger for sensitive systems. We don't allow any additives throughout our supply chain.

  • No Major Allergens: Cross-contamination and hidden allergens can derail your entire day. Our products are free from the top 8 allergens and rigorously tested for safety.

  • No Synthetic Isolates: Lab-created vitamins often absorb poorly and can stress your liver. We use only whole-food sourced minerals, vitamins, and nutrients your body recognizes and utilizes.

  • No Food Fragments: Processed "natural" ingredients can trigger sensitivities. We use complete, unprocessed sources that work with your body's wisdom, not against it.

  • No Heat Processing: High temperatures destroy delicate nutrients and create inflammatory compounds. Our gentle processing preserves nature's healing chemistry intact.

  • No Chemical Spraying: Pesticide residues accumulate in already-burdened bodies. Our wild-sourced ingredients avoid this unnecessary chemical contamination.
What's Your Commitment Beyond The Discount?
Healthcare costs shouldn't force you to choose between medications and quality nutrition. Once verified, your 35% discount never expires, but that's just the first step in how we support the chronic illness community.
  • Donations to Chronic Illness Nonprofits:
    We donate to organizations advancing research, advocacy, and support specific to chronic illness. Your purchase directly funds the change we all need to see.

  • Employing People with Chronic Illness:
    Who better understands your needs than those living it? Our team includes people living with chronic illness who bring lived experience to every decision we make.

  • Working with Chronic Illness Creators:
    We amplify voices from the community through paid partnerships and collaborations. Representation matters, and authentic stories drive understanding.

  • Award-Winning Short Film:
    Before we spent money on an any advertisement, we invested in a short film with 4 chronic illness creators to raise awareness for the silent struggles millions of people face on a daily basis.
