(7 H2s – fits the 5-8 range).

*FAQ H3s:*
1. Is it safe to take NMN and Resveratrol together?
2. How long does it take to see results from collagen supplements?
3. Can anti-aging supplements replace a healthy diet?
4. Are there specific supplements recommended for women over 50?
5. Do I need a prescription for longevity supplements?

*Schema:* Construct JSON-LD based on these FAQs.

*Banned Phrase Check:* I will scan the final output for “explore”, “shift”, “furthermore”, “moreover”, “comprehensive guide”, etc.

*Word Count Check:* I need to write substantially. I will expand on the “Why” and “How” in each section. I will describe the cellular processes in layman’s terms but with enough depth to add volume. I will discuss the nuances of bioavailability and formulation.

*Let’s start writing.*

*Self-Correction on Word Count:* 1800 words is quite long for a standard blog post renovation. I need to ensure I don’t repeat myself. I will add specific subsections within the paragraphs (without adding H3s except in the FAQ) to elaborate on study findings, specific dosages, and practical tips. I will expand the intro and the lifestyle section significantly.

*Refining H2s:* Ensure they are full questions.

*Wait, I need to check the H2 count again.* The prompt says “Exactly 5 to 8 H2 headings”. I have 7 planned. That is safe.
*Wait, I need to check the FAQ section.* “FAQ section at the end: 5 questions as H3 tags”. This is separate from the H2 count.
*Wait, I need to check the Schema.* “After the FAQ section, include a JSON-LD script block”.

*Let’s monitor the banned list closely.*
“in todays digital field” – Avoid.
“explore into” – Avoid.
“shift” – Avoid.
“its important to note” – Avoid.
“as an AI” – Avoid.
“change” – Avoid.
“in the ever-evolving” – Avoid.
“look no further” – Avoid.
“dive in” – Avoid.
“unlock the secrets” – Avoid.
“supercharge” – Avoid.
“seamlessly” – Avoid.
“cutting-edge” – Avoid.
“leverage” – Avoid.
“harness the power” – Avoid.
“navigate the complexities” – Avoid.
“comprehensive guide” – Avoid.
“Question…” – Avoid.
“FAQ…” – Avoid.
“furthermore” – Avoid.
“moreover” – Avoid.

*External Citations:* I need to link to real authoritative sites. I will use `href=”https://www.nih.gov”` or specific study URLs if I can recall them, but generic authoritative domains are safer for a renovation task unless I have specific URLs. I will use `https://www.nature.com/nataging` and `https://ods.od.nih.gov`.

*Word Count Expansion:* To hit 1800 words, I need to elaborate on each mechanism. For example, when discussing NAD+, I should explain the sirtuin pathway. When discussing Collagen, I should explain Type I vs Type III. When discussing Lifestyle, I should detail resistance training protocols.

*Let’s write.*

*Wait, one more check on H2 content:* “Each H2 section must have at least 2 paragraphs of content before the next H2”. I will ensure this strictly.

*Let’s begin.*

*(Self-Correction during drafting)*: I need to make sure I don’t accidentally use “FAQ” in the H2 or H3 text as a banned phrase context, though the prompt says “FAQ section at the end: 5 questions as H3 tags”. The banned list says “FAQ…” is banned. I should avoid using the word “FAQ” in the headings themselves. I will just use the questions as H3s. The prompt says “FAQ section at the end”, implying the section exists, but the banned list says “FAQ…”. I will avoid writing “Frequently Asked Questions” as a heading to be safe, just the H3 questions. Actually, the banned list says “FAQ…” likely meaning placeholder text like “FAQ…”. I will write full questions for H3.

*Wait, checking banned list again:* “FAQ…” is banned. I will not use the word “FAQ” in any heading. I will just have the H3 questions.

*Word Count Strategy:* I will write long, detailed paragraphs. I will break down the science thoroughly.

*Let’s go.*
