Stack Almanac for vegans
AI-powered supplement guidance that understands plant-based nutrition gaps and personalises recommendations for your biology.
Plant-based diets are associated with reduced risk of heart disease, type 2 diabetes, and certain cancers. But they also create specific nutritional gaps that are difficult to fill from food alone — and generic supplement advice rarely accounts for them properly.
Stack Almanac's AI advisor knows you're vegan from your personal profile. Every recommendation, interaction check, and insight is filtered through that context. It won't suggest fish oil when algae-based omega-3 exists. It won't recommend gelatin-based capsules. It knows which gaps are critical and which are overblown.
The challenges
B12 is non-negotiable but often neglected
B12 is the only vitamin completely absent from plant foods. Deficiency develops slowly and can cause irreversible neurological damage. Many vegans either don't supplement or use inadequate forms (cyanocobalamin vs active methylcobalamin).
Omega-3 confusion: ALA is not enough
Flaxseed and chia provide ALA, but conversion to the EPA and DHA your body actually needs is under 10%. Most vegans are functionally deficient in EPA/DHA unless supplementing with algae oil specifically.
Iron absorption is harder from plants
Non-heme iron from plant sources has significantly lower bioavailability than heme iron from animal products. Phytates in grains and legumes further reduce absorption. Supplementation may be necessary, especially for women.
Creatine stores are lower without meat
Creatine is found almost exclusively in animal products. Vegans typically have 20-30% lower muscle creatine stores, affecting both physical and cognitive performance.
How Stack Almanac helps
Diet-aware recommendations
Your personal profile includes diet type. The AI advisor automatically identifies vegan-specific gaps (B12, EPA/DHA, iron, creatine, zinc, iodine) and recommends plant-compatible forms — algae omega-3, methylcobalamin B12, iron bisglycinate with vitamin C, vegan D3 from lichen.
Personal insights
Track how supplements actually affect your energy, focus, and recovery. Stack Almanac shows you which additions made a measurable difference — not what a generic article says vegans should take, but what works for you specifically.
Interaction and absorption checking
The interaction database flags absorption conflicts relevant to plant-based routines — like iron and calcium competing, or phytates blocking zinc. Stack Almanac suggests optimal scheduling to maximise absorption from each supplement.
AI advisor that understands plant-based nutrition
Ask questions like 'am I getting enough DHA from my algae oil?' or 'should I take creatine as a vegan?' and get answers grounded in your actual supplements, consistency, and outcome data — not generic advice.
Vegan-verified restock
Smart Restock tracks your supply and links to vegan-verified products when it's time to reorder. No accidentally buying gelatin capsules or products tested on animals.
Example vegan foundation stack
This is a starting point. Stack Almanac personalises timing, doses, and additions based on your personal profile, goals, and personal data.
